Back to the Republic of China to be a editor

"Minister Tang, we have tested that the reliability of 50 and a half is even better than that of the original SKS." The manager said, "The composition of the steel used in 50 and a half is exactly the same as that of the Soviet SKS. In terms of manufacturing process, we have carefully adjusted the tolerance of each part. The standards, assembly process, and quality inspection specifications all use the standards set by Jianxin, which are said to be stricter than the Soviet arsenal."

Tang Hua nodded, "Very good. Now the production of 50 and a half, the main problem is the output. You started production on June 6, so far, how many pieces can the monthly output reach?"

Manager: "The 50-and-a-half production line now has a daily output of 400, and a monthly output of about [-]. According to the expansion plan of the General Administration of Ordnance Industry, the expansion of our workshop workers is already in progress, and the expansion of the production capacity of gun barrels has been completed. Other key parts The supporting capacity expansion plan is also underway.”

"The new goal is to achieve a monthly production of 50. The workshop workers are divided into two groups, half-old and half-new. Novices must be familiarized with the technology as soon as possible. During the expansion period, the manufacturing quality of [-] and a half cannot be reduced. The barrel is the main part and the It is right to pay attention to the difficulty of processing, but to double the production capacity, all parts must be considered, and even the production capacity of wooden pallets must be closely watched, and the chain cannot be lost because of small things.”

After watching the 50 and a half production line, Tang Hua continued to look at the production line of the 50-type squad machine gun.

The Type 50 class machine gun is the RPD light machine gun of the Soviet Union. This light machine gun was designed as a prototype in 1943. It was the first firearm to use 7.62X39 bullets, earlier than SKS.However, the Soviet Union probably disliked the lack of power of this kind of machine gun using intermediate rifle ammunition. After a few years of storage, the AK-47 began to produce equipment after mass production, but it was replaced by the RPK light machine gun, which is the same gun family as the AK-47. . RPD was equipped in the Soviet army for a short time, but in other countries, especially China, the Type 56 squad machine gun has been used for a long time.

Dalian Jianxin Company began to imitate RPD after getting the technical information, and now it has started mass production, only one month later than 50 and a half.

Flight 50 uses 100 rounds of ammunition to feed the chain drum, which probably has the best firepower continuity among the squad machine guns of this era. At this time, the U.S. military is still using BAR with 20 rounds of magazines.The first disadvantage is that there are only bursts and no single shots-Tang Hua pondered and waited for time to improve and improve.The second is that it is troublesome to refill the chain drum.But it is a bit troublesome to develop a real drum like the 81-type squad machine gun, and even the ammunition system on the gun has to be changed.

The output of 50 and 50 flights is basically synchronized, maintaining a ratio of 9:1.

Tang Hua began to mentally calculate the equipment of the Northeast Frontier Army.Now the Northeast Frontier Defense Army has 4 armies, each with more than 4 troops.But not an army needs more than 4 semi-automatic rifles. When the 38th Army entered North Korea to participate in the war, the entire army was equipped with 7000 rifles/carbines and more than 700 American-made carbines, plus submachine guns, light and heavy machine guns and short guns, and the entire army had about 50 guns.Because many arms and positions do not need to be equipped with guns. For example, the howitzer squad does not have guns, because they are basically useless.You give them a 38 and a half, he still thinks it is heavy.The cooking squad is also... well, the cooking squad of the [-]th Army may be equipped with guns.

往多了算，给每个军配1万支50半、1000支50班机，肯定是够用的。到10月1日，大连建新可以生产5万支50半，足够装备5个军。到12月1日是9万支——按我军入朝的速度，12月1日就有点赶不上了。

Tang Hua made up his mind to stop the production/repair lines of 38 and 99 rifles immediately, and then expand the production capacity to 3 per month.

The problems of rifles and squad machine guns have been solved, and submachine guns must be used for the time being until AK-47 arrives.But this is enough to make our army's team weapons comparable to those of the US military, and they are lighter, more flexible, and have stronger firepower.

Just benchmarking is not enough, Tang Hua needs an overwhelming weapon to use the asymmetry of technology to gain an advantage.

This weapon...is the new concept project that Tang Hua wants to give to the army.

Chapter 53, the second of the three great artifacts!

"Is this the super bazooka? America's most powerful individual anti-tank weapon?"

Build a new company anti-tank weapons branch.Tang Hua picked up a large steel pipe with a length of more than 1.5 meters and weighed it. The empty tube without rockets weighs 6.5 kilograms, which is heavy enough.He raised the steel pipe and took a look at his shoulder, shook his head, and threw the bazooka away.

"This American weapon is not very good."

Now, there are two mainstream individual anti-tank weapons.One is the German "Iron Fist" and the Soviet imitation RPG-1, and the improved version RPG-2 of the imitation (just started to develop).One is the "Bazooka" series and imitations.

"Iron Fist" is not actually a rocket launcher. Strictly speaking, it is a low-pressure recoilless gun that fires front-loaded super-caliber shells.Pull the trigger, "bang", a projectile flew out in a wide arc.As a momentum balance, the barrel ejects many powdery counterweights backwards.Due to the gratifying muzzle velocity, the effective range of the "Iron Fist" is not much farther than that of the grenade, and the RPG-1 has limited improvement.

The Bazooka and Super Bazooka are serious anti-tank rocket launchers.The launcher is a long steel pipe. The rocket is inserted through the butt of the steel pipe. When the trigger is pulled, the rocket shoots fire backwards. When the rocket moves to the front of the pipe and before it flies out of the steel pipe, the propellant burns out and the rocket stops. .This is necessary. If the rocket ejects the tube and the engine is still breathing, the shooter may become a roast pig.

In order to allow the rocket to accelerate a little longer, the tube of the "Super Bazooka" is so long that it must be disassembled into two sections for two soldiers to carry, otherwise it cannot be carried on the march.If the soldiers carrying the two steel pipes lose each other during the battle, one of them is killed, or his ankle is sprained and left behind, the bazooka will be useless.

Even with a tube of 1.5 meters, the initial velocity of the rocket launched by the "Super Bazooka" is only average, and the effective range is 200 meters. The regulations require that it is best to fire when the tank is within 100 meters.

Tang Hua knew that in the 21st century, the genre of "bazooka" won and became the main form of individual bazooka.But that is based on high-thrust super-speeding combustion engines and solid propellants of nanotechnology. Where can I find these black technologies now.

"I know that you have already started imitating the super bazooka after you got it, and the efficiency is very high." Tang Hua said, "Now, according to the new equipment plan of the General Administration of Ordnance Industry and the Logistics Department of the Military Commission, the technology of individual anti-tank weapons Tactical indicators put forward higher requirements and need to be redeveloped. Of course, your work is also fruitful, which can be regarded as technical preparations for the development of new individual anti-tank weapons. Secretary Li, what is the imitation of the super bazooka now? Have the parts been self-made?"

"The launching tube of the rocket launcher can already be manufactured," said Li Zhuping, secretary of the anti-tank weapon branch factory. "The solid propellant powder of the rocket motor has been imitated successfully. A batch of experimental products have been produced, and they are planning to conduct armor penetration tests."

"First, find a master who manufactures 57 recoilless guns to join the design team, preferably someone who is familiar with recoilless gun propellants; second, all members of the bazooka imitation team join the new design team, and the team leader is Xie Guangxuan. If we need to add some new manpower, engineers and master craftsmen will do.”

During the meeting the next day, in addition to the super bazooka yesterday, the long table in front of Tang Hua also had an "iron fist" and a big iron pipe with a length and diameter similar to the super bazooka.

"This is the German Iron Fist. It is launched without recoil. The initial velocity of the projectile is about 40 meters per second, and the range is very short."

"This is a Type 90 [-]mm paratrooper anti-tank rocket launcher made in Japan. It is a trial production model found in Shenyang." Tang Hua said, "In fact, it is a relative of this super bazooka. But now I am interested in it rockets."

Tang Hua picked up a Japanese anti-tank rocket.Strictly speaking, this is called a turbo spin-stabilized rocket. There are six inclined jet holes arranged evenly along the circumference at the tail. After ignition, it can not only propel the rocket forward, but also generate spin.

"The current bazooka is too bulky and heavy, and it is not suitable for infantry to carry, especially our infantry who mainly march on foot. Therefore, we cannot directly imitate the super bazooka. We need to reorganize the design team and re-edit the plan."

"Let me set a general direction first. The new rocket launcher should adopt a low-pressure recoilless-rocket engine hybrid scheme. The rocket is fired out of the chamber in the form of a recoilless gun. After flying out of a safe distance, the engine is ignited and the rocket is fired again. Accelerate to achieve a longer range. The rocket engine refers to the four-type rocket launcher, using multi-nozzle spin. The launch tube is not a non-pressurized structure like a rocket launcher, nor is it a relatively high chamber pressure like a recoilless gun, but it has to withstand A relatively low chamber pressure. Mr. Xie, you come to design a detailed rocket layout plan."

"If the rocket adopts the iron fist-style super-caliber mode, the arrow-shaped missile, the stability of the rocket's flight is the key," said Xie Guangxuan, the leader of the design team, "I will come up with a layout plan within three days."

"The design team and the recoilless gun master, please calculate the required tube wall thickness as soon as possible." Tang Hua added, "The diameter of the launch tube does not need to be 89 mm, it should be set at 40 mm."

Under the dispatch of Secretary Li, the anti-tank weapons branch immediately started to ping-pong-pong.

Of course, there is no need for Tang Hua to keep an eye on it all the time. When the design enters the next stage, Tang Hua can go and see if the design team has gone astray.

Xie Guangxuan is the designer of the Type 51 90mm rocket launcher, so it is most suitable for him to do it himself.As an early cross-border leader in the military industry system of the Republic, Xie Guangxuan can produce surprising works no matter what model he makes. (He switched jobs after designing the Type 51 rocket launcher, and his second work was the Long March [-] launch vehicle.)

……

Tang Hua still needs to dial another factory.

On the edge of Dalian Jianxin Company's factory area, close to the suburban forest, there are several small red factory buildings and a large golden workshop.

There lived an old man with a white beard.Grandpa can build bazookas.

Zhong Lin, who participated in the labor movement in 1923, experienced the May 1925th massacre in 1926. In 918, he worked as a mechanic in the Northeast Arsenal and experienced 1947 in person.After returning to the customs, he worked as an engineer at the Hanyang Gunpowder Factory and experienced the fall of Wuhan.Later, he sought a job in the Chongqing Military Industry Administration and experienced the Chongqing bombing. In 1948, he came to the base area. In 102, he set up a rocket technology room in the North China Arsenal, and made the first 1949mm multiple rocket launcher in the workshop. In [-], when the North China military factory was adjusted, Zhong Lin brought his rocket launcher technology room to Dalian and became a branch of Jianxin Company.

Seeing Tang Hua, Mr. Zhong started talking about the treasures in his factory.

"This A3 rocket launcher was short of materials when I was making it in North China, and many parts were of poor quality. The conditions in Dalian are much better. The range of the rockets made before was 5000 meters, and now it is more than 500 meters."

"The directional pipes are now cut out with foreign machine tools in Dalian, which are much more accurate than those made before..."

Mr. Zhong has even grander plans.The machines of Jianxin Company are good, the steel is good, and the gunpowder is also good.Now Mr. Zhong is thinking that the bazooka also needs to be replaced with a shotgun.A bigger guy is being designed, a 152mm caliber heavy rocket launcher, with a much higher power and range.It is that this thing may not be able to move the horse, it must be a vehicle-mounted rocket launcher.

"Mr. Zhong, Mr. Zhong," Tang Hua interrupted Mr. Zhong's eloquent blueprint description, and handed over the document, "The General Administration of Ordnance Industry has issued a new plan for the rocket launcher. You have a new development task, but it is not 152 mm. Heavy rocket launcher..."

The 152mm rocket launcher planned by Mr. Zhong is probably an enhanced version of the Katyusha. Its range is similar to that of the 132mm Katyusha, and it is more powerful.

But if the War to Resist US Aggression and Aid Korea starts, the Soviet Union will definitely increase its assistance. Not only the 122 and 152 howitzers negotiated before, but also Katyusha will also be sent over.

The production capacity of the domestic military industry is still insufficient. If you can ask the big brother of the Soviet Union to ask for something, if it is not particularly high-tech, then it is best to ask for it first.

The planning of the General Administration of Ordnance Industry is only one page, and the research and development tasks are also one page.After reading these two pages, Mr. Zhong looked up at Tang Hua.

"Develop a lightweight multiple rocket launcher with a caliber of 100 to 110 mm? Is it still my A3 rocket launcher?"

The 102mm rocket launcher developed by Mr. Zhong is called the A3 type in the factory, and the 50-type rocket launcher is generally called the Type [-] rocket launcher in the army.It was used in the War to Resist U.S. Aggression and Aid Korea. After a large number of Katyusha arrived, it was transferred to Vietnam to fight the French.

"Mr. Zhong, the level of motorization of our army is very low, and there are many mountains and hills in the territory, which is not suitable for the deployment of heavy mechanized troops." Tang Hua explained, "Therefore, there is an urgent need to develop a mule-horse-drawn, It is a lightweight multiple rocket launcher suitable for use in mountains. Moreover, this kind of rocket launcher can be used by regular troops, even guerrillas.”

Tang Hua drew a sketch on paper with a pencil and a ruler.

"First of all, for the new rocket launcher, the length of the rocket is appropriately shortened, and the length of the directional tube is also appropriately shortened. Second, the tail of the rocket is canceled. Third, the rotation of the engine 6 nozzle is deflected to maintain the flight stability of the rocket."

Mr. Zhong could understand Tang Hua's schematic diagram and asked, "Why did you cancel the fins? The fins are the lightest solution to keep the rocket stable."

"Yes, yes, the deflection of the 6 nozzles of the engine will reduce the thrust vector of the rocket to the front by 10% under the same thrust, and the performance gain brought by the cancellation of the empennage to the rocket is not enough to make up for this 10% loss. Tang Hua said, "However, this allows rockets to be launched in an emergency without rocket mounts or directional tubes and ensures high hit accuracy."
