1959: Carrying the achievement system, she rolled

64 September

The scorching sun baked the earth. On the test range, a mighty and majestic tank stood in the middle. Even the wall was demolished for this test.

Director Liu thought that instead of letting others knock him down, it would be better for him to take the initiative.

There were several people inside and outside the new tank, doing the final inspection.

The people who came to watch the test launch today included not only people from the entire institute, but also people from the National Defense Science and Technology Commission and the military region.

Therefore, there cannot be any mistakes in today's test launch. The research started in early June 62 and has lasted for more than two years.

It can be said that the research institute is burning money every day. If it fails to produce anything serious, being embarrassed is a small matter. It is they who feel guilty towards the country!

Even the chef in the cafeteria threw away his big spatula and stood outside the crowd, looking forward to it.

The chef at this time seemed to be a little thinner than in the previous two years. A chef who deals with food every day not only did not gain weight, but became thinner instead.

The reason is obvious. The hard work is one thing, but he also leaves all the profitable things to others.

The hot weather caused beads of sweat to appear on everyone's forehead.

But no one had the time to pay attention to it. At most, they would wipe the sweat off their eyes when it flowed into their eyes.

In addition to the chief designer Du Yimeng, the person in charge of each laboratory is also responsible for the final inspection.

From the day the new tank was formed, they never stopped testing, finding problems and then solving them.

For example, because artillery shells were too heavy, in order to reduce the physical burden and save time loading shells, they developed an automatic loader to replace manual loading of shells.

The initial design inspiration came from the magazine of a firearm. The projectile and cartridge were placed together in the training trough and then loaded into the barrel together.

The firing rate is as high as 9 rounds per minute, which does save physical strength and time, but problems also arise.

Because this loading mechanism is too complicated, it is also prone to malfunction and damage.

After repeated tests, the ammunition has now been changed to split-pack ammunition, which means that the projectiles and the charge are placed on the upper and lower discs respectively.

However, the main gun's rate of fire also dropped from 9 rounds per minute to 6-8 rounds per minute. No one was unhappy about this; solving the problem was the most important thing.

At first, they changed the rifled gun into a smoothbore gun. After the improvement was successful, the caliber of the smoothbore gun was 115 mm. In the end, they found that the firepower still did not meet their requirements.

The idea was rejected directly, and a new 125mm smoothbore gun was developed. This type of gun has a relatively long barrel, a single-piece structure, and a horizontal wedge sliding breech block.

There is a cylindrical exhaust device in the center of the turret, and four sections of light metal sheath are also installed on the outside of the turret.

This can extend the life of the barrel.

The front part of the vehicle body adopts a composite armor structure, which is the composite protective armor made by using the physical properties of ceramics discussed by Du Yimeng and Qiao Gong.

The tank's body is welded with armored steel plates. There is a V-shaped bulge in the center of the front upper armor plate of the body, with three horizontal ribs installed in it, so that the bulge can act as a wave-breaking plate.

It can improve the stability and safety of the tank when wading and crossing puddles, and protect the tank crew from the effects of dust and waves.

Especially when the water level is deep, it can prevent water from entering the vehicle body, thereby protecting the tank's engine and electronic equipment from damage.

Its design is inspired by river embankments. As the saying goes, technology comes from life.

Since their new tanks are designed to prepare for future nuclear battlefields, they installed a lead-containing radiation-proof lining on the inner wall of the crew compartment to protect the safety of the crew.

The turret is equivalent to a mobile fortress, so its frontal hit rate is very high. To reduce its hit rate, they designed it into an oval shape with a disc-shaped top view.

As a result, its height is much shorter than that of the Type 59 tank's turret. A smaller target means its survivability is higher.

The Type 59 tank uses a fixed-shaft gearbox with five forward gears and one reverse gear.

The transmission system of the new tank is a mechanical planetary gearbox with 7 forward gears and 1 reverse gear, and uses a hydraulic control system.

It uses a dual-flow transmission and a new track, a torsion bar suspension system, and a hydro-pneumatic suspension device on three pairs of road wheels.

It can enable the new tank to travel more smoothly on rugged terrain, increase its maximum speed in off-road conditions, and enhance its capabilities while moving.

After Du Yimeng and other responsible persons finished the inspection, everyone looked at the new tank with burning eyes. This was what they had been working for for more than two years.

It can be said that day and night, their minds are all on the new tanks.

Take Du Yimeng for example. When other laboratories encounter problems, they come to her and she is responsible for solving them because she is the chief designer.

Not only that, she developed the entire fire control system herself, and when she encountered problems, she had to solve them herself because no one else could help her.

Fortunately, Fang Bao is also a filial son. Knowing that she is busy with work, she stopped breastfeeding and only fed her baby with formula when she was six months old.

The person they should thank the most should be Captain Hao. When the couple was busy, it was Captain Hao, the super dad, who helped take care of the children.

"The inspection is complete. Why are you still standing here? Get out of here! I'm going to conduct a test firing." Wan Ping stuck his head out of the tank and urged.

He was the one who trial-produced the ammunition and tested it, and there was nothing wrong with it.

As for the two operators inside, he simply ignored them.

After Du Yimeng tricked him during the rocket launcher test, he never wanted to test launch with her again.

That's why he pushed her out without hesitation, because she was the chief designer and needed to be outside to take charge of the overall situation.

Qin Chulong looked at Wan Ping with disgust, then turned and left, while the others glared at him fiercely.

Just now they all wanted to stay and test-fire it themselves, but he refused to listen, no matter what they said openly or secretly, he just refused to do it!

They can't use tough measures because they still have to save face, unlike him, who is shameless.

Without any delay, they turned around and headed to the target location where they still had to record data.

"Get ready..." the operator holding the command flag shouted at the top of his lungs.

I don’t know if it’s because he was shouting splits, but everyone could hear the trembling in his voice.

Everyone subconsciously held their breath, stood on high alert, and fixed their eyes on the new tank.

"Fire..." With the operator holding the command flag, a grenade was ejected from the gun of the new tank, and the grenade with flames shot into the distance.
