Canteen System Assistance Notes

Zhu Dunzhong breathed a sigh of relief, but after a moment's hesitation, he couldn't help but ask, "Without the Soviet big brother this time, is the one in the tube a 'long strip' or a 'short and thick melon'?"

This time, Zhong Weilin did not answer.

He simply held his hands horizontally, stretched them out to the left and right, gestured a long distance, and then continued, "Commander Zhu, this time we must properly celebrate the comrades who have contributed so much. Completing such a large project requires not only a celebration banquet, but also allowances and vacations. Consultant Liu repeatedly reminded us that while everyone is enthusiastic and willing to keep working hard, mistakes are more likely to occur if you don't get enough rest. It's better to combine work and rest for greater efficiency..."

"Yeah yeah....""

Zhu Dunzhong finally revealed a satisfied smile. He nodded and continued to clap his hands in a formal manner.

Chapter 746: Lucheng is a nest of "technical masters"

S.G. Pererushev was a project engineer and a project designer assigned to Factory 592 by the Red Army Artillery General Directorate.

This position held a unique position within the Soviet military-industrial complex. It could be responsible for a subsystem within a large project, or it could be responsible for the overall management of a smaller project. Comrade Pererushev likely fell into the latter category—at Factory 592, he was responsible for the repair, modification, and commissioning of equipment brought into the USSR through the Lend-Lease Act. When British and American supplies were scarce, he would also repair and modify captured German tanks for his own use.

So, in short, Comrade Pererushev might not have had Comrade Morozov's ability to lead a project and pioneer a new direction, but he was definitely more than capable in terms of craftsmanship and design experience. For example, he thought the German Panzer III and Panzer IV were both terrible, but the Panzer III's gearbox was a really good design, and the Panzer IV's commander's cupola was quite good and could be copied. Furthermore, the gunner's scopes on both were excellent, while the American gunner's turrets were utterly awful, even worse than the Soviets'.

However, at the beginning of 42, he suddenly received an order from his superiors, asking him to take two assistants, form a team, and immediately go to China. China?

Oh...it turns out that the organization "sold" me.

The Nizhny Tagil-Ural Tank Plant, rapidly advancing research on a "T-34 successor tank," was short of production capacity for key materials and was forced to seek assistance from Chinese comrades. The Chinese, already struggling financially, generously offered their assistance and even participated in the tank's design. As compensation, the GAU decided to dispatch two teams of designers and engineers to China to help them modify tanks imported from Western countries.

Well, it's a good deal.

Regardless of the fact that the 592 Factory had super-hard turning tools produced in China, Comrade Pererushev himself had eaten canned red bean paste sent by Chinese comrades. It was also very reasonable for him to exchange a few years of his service to China for a round of supplies. Moreover, when the GAU staff came to convey the order "You are going to China", they could not help but envy in their eyes - the working conditions over there were obviously good.

He quickly boarded a Northern Airlines plane and headed south with BN Andronov from Factory 92 and Comrade AV Kolesnikov, who was handing over personnel from Nizhny Tagil-Ural to the Chinese side. After almost two days of flying, they soon arrived at an airport next to a large river.

"Deer City".

AV Kolesnikov handed over some information to the Chinese comrades, introduced himself and another comrade Andronov to the Chinese comrades, then had a closed-door conversation with a famous firearms designer Comrade Liu He, and then left by plane.

This must be Comrade Morozov's task... Are they planning to install new machine guns on the new tanks?

Pererushev quickly put the thought behind him. It was Chinese New Year, and he took the opportunity to take a good look at his workplace for the next few years—a coal-fired power plant (the coal was surprisingly shipped in by rail), a newly established steel mill (for unknown reasons, a large area had been fenced off when production was low, with a valley dedicated to slag dumping), and an inland port with paved roads and a coexistence of manpower and machinery.

And all this was accomplished when the entire city was still mostly made of earthenware and bullet heads could be found among the wreckage of the city walls. It was outrageous, yet strangely familiar.

Pererushev, feeling unexpectedly friendly, quickly got to work after a brief welcome. To facilitate coordination, the Chinese comrades assigned him two university-level mechanical engineering graduates and a technical translator named "Sergey" (Russian)—a person with both technical vocabulary and foreign language skills was invaluable even in the Soviet Union—to assist him in connecting with the original technical team and worker representatives at the Lucheng Vehicle Works.

He was ready to lead a group of young men to build something from scratch in a poor place.

"Oh! This is your achievement..."

It turns out that Lucheng Vehicle Factory has its own design team...

The fake Ryrushev, who was full of revolutionary fearlessness, and Andronov, who was eating a bunch of bananas crazily, ultimately failed to use their willpower to overcome all difficulties. They soon saw the results of the Eighth Route Army technical team - a group of very young and creative guys with a scientific spirit and very unscientific, or daring to break the rules, strange ideas.

They had already achieved some results when they were in Ning Province and Guanzhong.

例如，他们将对远东方面军转交的BT-7坦克进行了改装--中国同志先前就有装备一些26和BT-5，只不过这些坦克里只有BT-7的状况还好一些了--将其引擎更换为了苏制V-2柴油引擎，并将坦克的传动系统改进到了BT-7M的水平。

This was a very good result for a fledgling design team, but they were clearly not satisfied with it. Based on the fact that "tank battles on the Chinese battlefield were actually rare, and the Japanese tanks were few and fragile", they removed the 45mm gun from the tank, modified the turret design, and installed a US-made M1 75mm howitzer, allowing it to play the role of an "artillery tank" to replace the SI-5 self-propelled artillery that had been retired due to exhaustion of motor hours.

At the same time, they also carried out a variety of modifications on the only British armored vehicle they could produce independently, the 'Big Bren': some sacrificed the 4-person crew cabin, retaining only the positive and negative driver seats, and installed an 82mm mortar or an 82mm recoilless rifle; some installed a flip rack on the rear of the vehicle and installed a 100mm mortar...

The style of these things is quite normal. After all, Pererushev had seen this kind of British car in the Soviet Union and had modified it before. But...

What the hell is this thing with a flamethrower installed in the enclosed crew cabin? What the hell is this thing with a 107mm recoilless rifle slung along the centerline of the vehicle? What the hell is this thing with a 14.5mm machine gun stuffed in it?

"Isn't that quite creative? Young man, creativity is the lifeblood of many designers. You can be without work, but you can be without creativity. Out of 100 ideas, there will always be one or two masterpieces."

BN Andronov, munching on a banana, didn't have Pererushev's "old man on the subway phone" expression at all. Instead, he gave the Eighth Route Army's young technical team a thumbs-up. "Bren is indeed a good platform, as long as you don't send her to the front lines. I think the versions equipped with anti-aircraft machine guns and 107mm cannons have their value and can be further improved..."

"The version with a flamethrower installed directly is indeed a bit too radical." He added, "But you can adjust the layout of the flamethrower and then strengthen its front armor if the suspension allows!" "No! No, no, please wait a moment, my friend."

Seeing the students' eyes light up, as they immediately pulled out their notebooks and prepared to record their knowledge, Pererushev covered his head and said, "What nonsense are you talking about? Don't exploit these poor little cars too much... What are you planning to do with so many sub-models?"

"Oh, Comrade Pererushev, the 107mm recoilless rifle version of the Big Bren is what we're planning to use to replace the 82mm recoilless rifle version. It can be used as a mobile artillery piece, providing fire support to reconnaissance units or simply as a self-propelled gun mount. The Big Bren with the 14.5mm machine gun can be used for air defense... ahem, actually, it's mainly because the troops have discovered that the mere presence of the 14.5mm machine gun on the battlefield will cause the Japanese to surrender..."

The leading Chinese guy immediately replied, "As for the flamethrower version, we plan to use it as equipment for chemical defense troops. You know, the Japanese fascists are very brutal, and they might use chemical weapons against our soldiers..." "Okay! That's no problem, but! Isn't the most important and urgent thing right now to transform and refurbish larger tanks?"

S.G. Pererushev, who finally made the style of Lucheng Vehicle Plant more normal, finally started the formal project.

I have to say that, apart from sometimes not being able to keep up with the ideas, these Chinese guys have very good hands-on skills.

They first completed the replacement of some of the "Valentin" tanks with Soviet 45mm tank guns.

Design work was carried out, and tanks that did not have time to modify their artillery were equipped with "improvised high-explosive shells" modified from Bofors anti-aircraft gun warheads.

The Eighth Route Army's designers also devised a simple gun mount to make use of the remaining power of the British 2-pounder guns. It was said that some of the Nationalist government's armies in the south were still lacking anti-tank firepower, and these guns would have no trouble finding buyers. With Valentine's modification plan finalized and transferred to the factory for construction, the Lucheng design team began to improve and adjust the Eighth Route Army's newly received M3-Stuart and M3-Grant guns.

The Eighth Route Army soldiers had considered removing all the American 37mm guns from the two M3 tanks and replacing them with Soviet 45mm guns, but ultimately abandoned the plan due to the sheer volume of American tanks being delivered and the sheer workload and expense of completing the modifications. Under Pererushev's leadership, the design team began tinkering with the American M3-Grant tanks.

"Young Chinese comrades, don't be afraid of difficulties! I once presided over the improvement of the 'SG-122' assault gun in the Soviet Union, converting Nazi Germany's Type 3 tank into a Soviet-made 122mm gun!" At this time, the experienced project chief engineer S.G. Pererushev played the role of the backbone of the team. He encouraged the Eighth Route Army technicians who were first exposed to such a tonnage "heavy tank" and said, "The chassis and suspension of the Grant tank are better than the Type 3 tank. The Grant in China still uses the high-powered version with a diesel engine, so we

-It will definitely succeed!"

Under the leadership of two Soviet experts, the Eighth Route Army was divided into two experimental groups and carried out their work in full swing.

At the Lucheng Vehicle Plant, which was still in the state of "construction and production at the same time", under the command of Pererushev, several American-made M3 Grants gradually became "naked" from complete, and then became complete again from "naked".

Although the completed Grant lost the 37mm M5 anti-tank gun and 75mm M3 howitzer, and gained a 122mm cannon with a large sheath, it looked a bit out of place, but the front armor covered with "leek boxes" exuded a reassuring sense of heaviness.

1942 was a fleeting time. As the year drew to a close, the Eighth Route Army's first "greatly modified tank"—an M30 122mm howitzer and electric high-powered anti-tank—was launched.

The tank has a low-profile design, and the fixed fighting compartment has been restructured and the front armor of the tank has been rearranged.

The "Lant-122 assault gun" has finally entered the stage of "modification completed and full vehicle testing".

The tanks were rumbling around in circles on the test track. Looking at the fruits of his labor this year and the Eighth Route Army soldiers standing ready with their repair tools, he

S.G. Pererushev felt a genuine joy.

I've finally made some progress...

He should have been in a good mood—if at this moment, the loud-mouthed Comrade BN Andronov had not led another group of cheering Chinese technicians to the other end of the test field, driving a "Stuart with four 107mm recoilless rifles on top," a "Stuart with a 107mm rocket launcher on its back," and an "M3 half-track carrier with twin 14.5mm machine guns..."

It's even better.

Chapter 747: New air force detected approaching

(Update)

"Cola, this is Chips 02, already eyeing Leba. Over."

"Cola received. French Fries 02, maintain visual tracking and fly safely. French Fries 02, keep breathing evenly." "French Fries 02 understands - these pants are a bit tight."

Two Corsair R fighters painted in desert camouflage climbed to altitude and caught up with a twin-engine bomber numbered "8T" - this bomber was painted in brown, green and gray Soviet camouflage, but it also had the "red star and Chinese characters" logo of the Eighth Route Army Air Force painted on it to cover up the fact, and the blue and white stripes of the Chinese Air Force identification stripes painted on the vertical rudder - this was a rare Ye-2 bomber.

Following it was another Ye-2 of the same type, and the two aircraft were cruising steadily at an altitude of 3000 meters.

The pilot, codenamed "French Fries 02," felt his legs. His new flight pants were stiff and uncomfortable from being inflated. Considering today's mission was to accompany and escort the pilot, he fumbled around on his left hand side and lowered a valve marked "compensation ratio." He felt the air in his pants weaken considerably, and his legs suddenly felt lighter.

He immediately breathed a sigh of relief and felt a lot more relaxed.

The warm air jets from the engines were very comfortable, and the elevated seats and bubble-shaped cockpit provided a view that was almost luxurious. The pilot gently moved the joystick and moved with his wingman toward the two "Ye 2s". He then gently shook his wings to show his goodwill.

Then, Chinese with a Maoist accent came over the radio.

"Hala Shao, this is China's Dawalishi. This is Leba 07, nice to meet you." "Hala Shao, Leba 07, this is French Fries 02, I wish our experiment goes well."

Unfortunately, up to this point, the Eighth Route Army's aviation corps, or rather, its air force, has not been able to rely entirely on domestically produced aircraft. Therefore, in the context of World War II, the use of aircraft from various countries was unavoidable.

The Hurricanes that first accompanied the Eighth Route Army have basically been retired, with only a small number of relatively good ones still serving on the second line. The "Wildcats" purchased in 1941 are also beginning to show some signs of fatigue. Now, the "Pirates" that entered China in 1942 are taking on the main responsibility of the Eighth Route Army's air control mission.

Because of the intervention of Liu Helian, the "communist tycoon", the joint venture with Ford, Tottenham Aviation, replaced the "Brewster Company" that had historically manufactured the Corsair, and began to produce land-based versions of the Corsair fighter for the Eighth Route Army and the US Marine Corps.

These Corsairs, renamed FR-1s after Stout-Stout Aviation, were different from the F41-1s produced by Chanceworth. Instead, they were more like the FG-1s produced by Goodyear. They featured a cutting-edge blister canopy and anti-roll bars, and optional extended footrests to accommodate the pilot's vision and height.

At the same time, considering that these aircraft do not need to take off and operate on aircraft carriers, and do not need to conserve fresh water, the folding mechanism on the inverted seagull wings and the tail landing hook were removed to reduce weight; the 20-horsepower R-280O engine was also equipped with a water injection device, which can provide the aircraft with 250 horsepower emergency power for 10 minutes.

After these aircraft were packed and shipped to Xinjiang Province, China, the Shihezi Aircraft Factory, which had already completed the production of the Il-4, assembled and debugged them before flying them back to the border region. Here, these FR-1 Corsairs underwent some modifications with Chinese characteristics.

Compared to the original version, the eight-route version of the FR-1-CN fighter is equipped with a cockpit floor made of flame-retardant material in the spacious aircraft cockpit, and the compressor, gas cylinders and control mechanisms are installed in the space under the floor. Compared with the original "sodium peroxide regeneration board", this device can provide safer oxygen-enriched air for the cabin and inflate the pilot's rubber tube anti-G pants when performing high-G maneuvers, providing an additional load resistance of approximately 1.5G.

So, apart from not being able to board ships, in a sense, the "pirates" of the Eighth Route Army are more useful than those of the US Navy.

Of course, given the Americans' consistent financial resources under the Lend-Lease Act, throughout 1942, in addition to purchasing and leasing Mitchell bombers, Hudson patrol planes, SBD attack planes, F-5 reconnaissance planes, and PBY seaplanes to form the Sino-American Air Force, the Eighth Route Army also inexplicably received over 70 TBD-1A torpedo planes from the Americans.

This is an American TBD torpedo bomber retired from an aircraft carrier, which was converted by the Dodge Osborne Earl Company into an aircraft that can operate in any water area longer than 300 meters and can carry more than 80N kg of payload. The reason for sending it to the Eighth Route Army was that they complained at a coordination meeting that they lacked a bomber suitable for use in river networks, which meant that the battle group facing the south was short of ground support aircraft.

While the United States was purchasing and sending large amounts of arms through the Lend-Lease Act, the Soviet Union did not stop its aviation exports to the liberated areas.

Although the 116 and 1153 aircraft originally equipped with the Eighth Route Army had basically been relegated to the background, with the 1941 "Statement of the Chinese and Soviet Peoples on Mutual Cooperation in the International Anti-Fascist War" and the subsequent "Sino-Soviet Peoples' Wartime Cooperation Plan", the liberated areas, as the safe rear base for the Soviet Union's large-scale industrial migration, also took over the transfer of many Soviet industrial and mining research institutes.

Among them, in addition to the Shihezi Aircraft Factory in Xinjiang Province, which is helping the Eighth Route Army assemble and modify Corsair, Mitchell and other aircraft, there is also the Guanzhong Liyang Aircraft City, which has basically taken shape and started production. This includes the aircraft design team headed by designer Comrade Nikolay Polikarpov and the "teaching group" headed by Vladimir Mikhailovich Myasishchev.

These two experts, each capable of leading a design team, not only personally taught the students sent by the Eighth Route Army, but also contributed many achievements to the Eighth Route Army.

Among these achievements, the most brilliant one must be the TK-3 fighter-bomber, which was developed from the ITP long-range escort fighter. Following testing in mid-1942, this aircraft has undergone further drag reduction and improvements, reaching the current limit of its capabilities:

It can now fly at low altitudes of 696 kilometers per hour (without a secondary boost) and 663 kilometers per hour (with a secondary boost at high altitude). In interception mode with half fuel and no fuel, it achieves a sea level climb rate of 27.2 meters per second (without a secondary boost at low altitude) and 23.2 meters per second (with a secondary boost at high altitude). It has a maximum payload capacity of 2.1 tons (at short-range fuel) and a range of 1975 kilometers when carrying a large auxiliary fuel tank. New Era, New Shareholders - Chapter 263 https://kdocs.cn/l/cncaGCrHYhAD

The first batch of eight low-altitude prototypes have been sent to the Soviet Army for trial, while the other eight medium- and high-altitude versions have been sent to Shanxi Province for testing, and all have received praise in their areas of expertise.

In the Soviet Union, this aircraft was welcomed by the Red Navy for its excellent vertical maneuverability, sturdy fuselage structure and ample range. In comparative tests, it defeated fighters including the Mig-3, YaK-9U, and L 5. Only in close combat was it defeated by a La-5Fn special aircraft that was equipped with Chinese-made aviation aluminum skin and alloy steel frame.

The Soviets believed the MiG-3 was suitable for North Sea escort missions, radar-guided interception, and long-range raids. They believed it should leverage its speed and vertical maneuverability to avoid close-range combat and expose its roll rate disadvantage. After deliberations by the Council of Ministers, the Soviets decided to produce the MiG-3 at the Moscow Aircraft Plant No. 1.

In China, this long-range aircraft was equipped with rocket pods and aerial bombs by the Eighth Route Army and used as a hunting bomber to search for Japanese heavy artillery on the move on the North China Plain. During the first few flights of the test squadron, the pilots of the Eighth Route Army were lucky enough to find the last Type 7 305mm artillery that was stealthily maneuvering along the railway, and successfully sent it to Kudanzaka to meet its predecessors.

Similar to the Soviet Union, the Eighth Route Army decided to produce this type of aircraft in the aircraft city of Liyang and use it as a fighter-bomber.

In addition, the subsystem and process teams led by Myasishchev are more responsible for teaching and talent training.

They not only helped the Eighth Route Army resolve the process issues of American engines but also successfully entered the field of aerodynamics. Under Myasishchev's guidance, the Eighth Route Army trainees gradually began to gain a basic understanding of aircraft aerodynamic design, gradually gaining a quantitative understanding of the advantages and disadvantages, trade-offs, and shortcomings of existing aircraft aerodynamic designs.

As homework for these aviation cadets, Myasishchev assigned them a task - to use the existing "Twin Wasp D" engine to design a transport aircraft suitable for China.

Of course, in the process of cooperating with the Eighth Route Army, which was far different from the historical Eighth Route Army, each partner also received some additional "return gifts".

Not only did the Americans gain access to the air bases in Xilin Gol and Shandong Province, enabling them to bomb Japan more smoothly, they also secured a promise from the Eighth Route Army that it would launch a major offensive within six months. This ensured that the Japanese army would not mobilize too many forces into the then-volatile Melanesia (called Outer Southeast Asia by Japan)—this way, President Roosevelt could peacefully implement the "Europe first, Asia later" strategy and concentrate on seizing US interests on the battlefields of Europe and North Africa.

The Soviets gained a secure rear area, a socialist fraternal party that finally saw its investment pay off. The logistical supplies and high-value-added industrial products sent back from China in the form of return tonnage became the "logistics of the Soviet logistics," gradually accumulating the "quantitative changes" in the Red Army's battlefield situation. These supplies continuously offset the accounts of aid to China, and even showed signs of gradually surpassing and creating a "debt."

In view of some "specially supplied equipment" that was in line with the background of the times but exceeded the Soviet technological level, Stalin and the Soviet Council of Ministers not only sent a young expert named Agyip Mikhailovich Lyulka, who was stationed in Chelyabinsk, in the second half of 1942 to share some equipment design drawings with the Eighth Route Army, but also sent a 32-plane "Ye 2" bomber regiment to the liberated areas.

According to the communication with the Chinese side, the 2nd Regiment of the Ye Army will undergo training and modification for about six months until they fully master the use and maintenance of the new weapons and equipment. In return, they can serve as volunteer air force and participate in tactical bombing missions designated by the Chinese Communist Party.

"Cola-Cola, Leba 07 reporting in, equipment inspection complete, airdrop preparations complete, please give instructions."

"Leba 07, this is Coke. Ready to begin the test. French Fries 02, French Fries 04, please maintain visual contact, maintain a safe distance, and complete the recording mission." "French Fries 02/04, received!"

"Okay, Chinese Davarish, aimers ready, machine gunners ready—fire!"

Accompanied by mixed radio signals from China and Russia, the Ye-2 bomber code-named Leba 07 jumped upward, and two bombs, which were modified and transformed from 50-kilogram low-drag bombs, broke away from its centerline hanging point one after another with sharp gyro acceleration sounds.

Immediately, it unfolded its two aluminum wings in the air and, with the help of its cross-shaped tail, quickly adjusted its position. Then, the two barrel-shaped structures at the tail began to emit long columns of smoke, propelling this dull creature at a steady descent rate and trajectory towards the distant target.

"Extended-range glide remote-controlled bomb, 18th launch test, begins!"

Su Kong's Thoughts (Part 1)

Mikhail, commander of the 141st Bomber Regiment of the Soviet Volunteer Air Force

Draft Manual for the Y5AK-500 Powered Gliding Guided Missile

Based on the results of joint training conducted by our unit with comrades from the Communist Party of China, as well as the translation of Chinese materials, we believe that it is entirely possible to launch V5Ak-5OO bombs from a Yer-2 bomber and conduct combat operations. We believe that the V5Ak-500 bomb is a powerful weapon. Through the sophisticated electromechanical logic design of our Chinese comrades, it can achieve combat efficiency far exceeding that of traditional bombers and has many unique applications. However, the Yer-500 bomb is also a sophisticated and complex weapon, with many fragile electronic components, requiring meticulous care.

Now, I will list the experiences we have summarized as follows:

1. The VBAk-500 is a glide bomb powered by a power engine. Its range is affected by the altitude, speed, and fuel load of the carrier aircraft. For example, the range of the Yer-2 bomber ranges from 5 to 20 kilometers. Therefore, to ensure a clear target, pre-combat reconnaissance of the intended target and the creation of a mission map are essential.

2. The V5Ai-5O0 bomb has a gyroscope and mercury column automatic trim function, which can withstand a certain degree of crosswind. However, to ensure the maximum effectiveness of the precious bomb, we recommend that detailed weather observations must be carried out before the operation, and bombing operations should only be carried out when the wind speed is below level 6 and visibility is good. At the same time, bombs should be dropped against the wind whenever possible. More @book@groupcom7751-11838

3. The V5Akt-500 bomb should normally be dropped from an altitude of 30 meters to 600 meters. When not remotely guided, it is dropped at an altitude of 300 meters and, over a 15-kilometer flight, will have a natural dispersion pattern of an ellipse with a minor axis of 250 meters and a major axis of 400 meters. Dropping at a higher altitude will extend the range but increase the dispersion area. We recommend that glide bomb attacks primarily target Nazi railroad bridges, train marshaling yards, marching trains, or logistics hubs.

4. Chinese comrades have prepared 18 remote control frequency bands for the V5At-5O0 bomb. After testing, four of them have the risk of mutual interference. Therefore, they recommend that in a 20-kilometer-wide combat airspace, it is best not to have 14 bombs in remote control mode.

However, thanks to the innovation of Sergeant Reznov of the 3rd Squadron of the 2nd Brigade, we have developed a new tactic of "simultaneous release and remote control." By ensuring that the two bombs are released from the carrier aircraft within a time interval of less than one second, two bombs can be remotely controlled using a single frequency band. Therefore, if the gunners and front gunners responsible for bomb remote control are fully trained, the number of controlled bombs in the combat airspace can be doubled.

5. The Y5AK-500 bomb can be remotely controlled in the left, right, front and back directions.

Before launch, the bombardier should set the base descent rate based on the aircraft's intended release altitude. If the bomb is being carried externally, the base descent rate should be set on the ground. This is done by turning the No. 9 and No. 8 limit screws on the cross-tail section. These two limit screws are interlocked and have scales. Before launch, check that the scales indicated by the two screws are synchronized; otherwise, the bomb will crash soon after release.

After launch, the remote control operator should maintain visual contact with the target and maintain the left and right remote-controlled warheads aligned with the target. Remote control movements should be gentle and steady, and large movements should be avoided. The sight will calculate the bomb's altitude based on the base descent rate, and the escort fighter pilot can also provide the bomb's altitude. However, to ensure accuracy, we recommend that the remote control operator refrain from adjusting the bomb's elevation angle unless there are special circumstances.

After launch, the carrier aircraft should continue to fly alongside the bomb, maintaining a straight line to facilitate remote control by the operator until the bomb impacts the target. However, if there are air defense positions near the target, the carrier aircraft may be damaged or hit. After repeated testing and discussions with Chinese colleagues, we believe that after the aimer can visually identify the target and confirm that the bomb will impact the target area approximately 6-8 kilometers at the current descent rate, the remote control can be removed and the aircraft can be turned away.

At this point, the expected dispersion of the bomb is an elliptical area with a short axis of 100 meters and a long axis of 200-250 meters. The final drop speed can reach 600-650 kilometers per hour.
