"How is the industrial production process of AT-20 high-energy explosives with GN-4 main oxidizer progressing?"

Yang Jie is concerned about whether this high-energy propellant can be successfully industrialized, and if it cannot be mass-produced, then it will be in vain.

After all, such a thing has not been done, and Da Mao has used ADN propellant in the engines of some air-to-air missiles, SS-24 missiles and Topol intercontinental missiles.

Due to the poor stability of ADN, in the 70s and 80s of the 20th century, there were four major explosions in the former Soviet Union in the process of developing ADN, so it is unknown what the performance will be.

Before Geng Baochang developed this solid propellant, the domestic research and development in this area also lasted for more than 20 years, and he has accumulated a lot of experience in this area.

"Thanks to Chief Engineer Chen, he has designed a unique industrial production route for synthetic AT-4 propellant, which has been tested and proved to be able to achieve large-scale production. ”

Geng Baochang said with great joy: "We are confident that in a relatively short period of time, we will reduce the production cost of AT-4 high-energy explosives to about 1,000 yuan per kilogram, so that the army can afford to buy and use it." ”

Since the components of AT-4 high-energy explosives can be introduced into various solid propellants, the energy level, specific impulse and combustion rate of these propellants can be greatly increased, and the range and speed of various strategic and tactical solid missiles can be increased without increasing weight, which is of extremely high strategic significance to China.

And because the molecular structure of this high-energy explosive does not contain chlorine, there will be no secondary smoke caused by hydrochloric acid smoke in the combustion products, so it presents a small characteristic signal, which also meets the requirements of Yang Shao's proposal to develop the next generation of stealth missiles. ”

Geng Baochang said excitedly.

Yang Jie's eyes also showed ecstasy.

In the afternoon, Yang Jie also specially inspected the production line for the production of AT-4 high-energy explosives, and when he saw the technicians taking out the cylindrical earthy yellow medicine column from the drying oven with anti-static gloves, he also carefully observed.

These high-energy explosives are very dangerous items, and technicians can clearly see whether there are air bubbles inside the column on the screen when they inspect the pharmaceutical equipment.

After the test is completed, the technician has to weigh it, put it in a sealed bag to remove the air, and put it into a special box, which is surrounded by cushion protection pads.

Yang Jie then also came to the workshop where the solid rocket engine was cast, and he also saw several solid rocket engines that had been poured, all of which were solid engines used in long-range air defense missiles.

At this time, the technician is controlling the pneumatic manipulator arm to extend into the cavity of the medicine column to finish the inside.

The mechanical arm is equipped with a camera and a strong illuminator, and the movements of the mechanical arm can be clearly seen.

With this set of pneumatic engraving equipment, the work efficiency of the medical face shaping department has also been greatly improved.

The next day, Yang Jie also came to the factory where the solid rocket engine was tested on the ground in a remote valley.

On the solid rocket engine test platform frame, this new solid rocket engine is fixed to the frame at this time.

As the technicians in the monitoring room pressed the ignition button, the solid rocket engine ignited, and the tail nozzle emitted a strong fire, but the smoke that obviously came out was much smaller than the previous smoke.

At this time, the detection equipment also shows the image of the combustion inside the rocket engine, and also shows the specific parameters such as temperature and pressure inside the solid rocket engine.

Geng Baochang stared at these parameter changes at this time.

"Yang Shao, this solid engine has met our design goals!"

Geng Baochang said excitedly to Yang Jie.

When the engine stopped working, there was warm applause in the monitoring room.

Yang Jie also happily shook hands with Geng Baochang and others, and said again and again: "Good job, good job!"

Although the solid rocket engine still needs to accept vibration, high temperature and low temperature experiments, a lot of work is still needed, at least after many ground hot car tests, and new problems may be encountered in the middle, but this solid rocket engine successfully completed the ground hot car test for the first time, which also made Geng Baochang and others happy.

Ground hot test is one of the two major nodes in the development of solid rocket engine models, when the focus is on the correctness and rationality of the engine technical scheme, as well as whether the materials used and the manufacturability are up to standard, and whether they are reliable in the simulated natural environment.

After the successful completion of the ground hot test node, it will soon enter the next major node - flight demonstration test.

The next link focuses on assessing the performance of the entire engine flight, testing the working performance of the solid rocket engine under real natural environmental conditions, such as different air pressures at high and low altitudes.

It will take at least more than a year for the whole process to go smoothly, and it will be much longer if there are engineering problems in the middle.

However, since the introduction of digital prototype simulation test platform technology, the entire missile design, production and manufacturing and even flight tests have been simulated and tested.

Huaxing Group Co., Ltd. has mastered a large amount of data in the development of aircraft, aero engines and a large number of wind tunnel tests, which will naturally not lie there to sleep, but are used by the simulation software department of Huaxing Group to establish a highly accurate atmospheric environment simulation test software, which is very close to the data obtained by the software simulation test and the actual test.

This also means that the flight test time of Sinoking Aviation Technology will be greatly reduced.

If it were other software vendors, they would not be able to get so much data, because these large enterprises are separated from each other, and even if they cooperate, they can only get part of the data.

This is also the real reason why the simulation test software developed by the simulation software department of Huaxing Group will be so accurate.

It is also the reason for the high accuracy of simulation testing software, and now the entire Huaxing Group is benefiting from this, the original R & D cost of the largest real test has been greatly reduced, R & D costs have also been reduced, R & D technicians are mainly focused on design, production and manufacturing, and the profit margin of the entire group company has also been significantly improved.
