"Yang Shao, we have done more than 500 experiments, and finally fixed the formula of this high-energy propellant, and now we are about to experiment with the shape of the chamber of several medicine columns designed to select the most suitable cavity shape for combustion speed. ”

Chen Haitong said.

The combustion mode and structure of a solid rocket are no different from the principle of bullet propellant and artillery propellant, if there is any difference, the energy of solid rocket fuel is higher, and to continue to burn steadily for several hundred seconds, the design of the shape of the internal cavity of the cartridge is extremely particular.

Chen Haitong has led the R&D team to develop high-energy bullet propellants in recent years, and has also undertaken the development of rocket propellants.

Like the formula and processing technology of solid rocket propellant are the embodiment of the strength of military affairs, these formulas and processes are the secret technology of the bottom of the box of various countries, in this regard, the eagle sauce technology and technology is the best, the production of Trident 2D5 missile, with only a length of 13 meters can bring eight warheads to hit targets tens of thousands of kilometers away, and countries such as Da Mao and Rabbit to achieve this level of missiles will have to increase the length to more than 15 meters,.

Whether it is a small air-to-air missile or a large intercontinental missile, Eagle Sauce can make the solid engine the lightest and shortest, which is its high level of high-energy propellant.

After organizing the technical team led by Geng Baochang, Huake Aviation Science and Technology Corporation also redesigned the solid-fuel engine, and Chen Haitong's technical team also became a technical consultant.

Chen Haitong has become the top expert in the research and development of propellants, and under his leadership, the technical team has to conduct experiments at least twice a day to find out the formula and process of rocket solid fuel.

An hour later, Yang Jie also saw the combustion of the medicine column installed in the container in the combustion chamber laboratory of the experimental building - infrared high-speed camera, piezoelectric transmission test system, terahertz imaging radar and other equipment At this time, the internal combustion of the medicine column was captured and presented on the screen, and the temperature, pressure and other parameters inside the combustion chamber were completely recorded.

"Yang Shao, the combustion chamber in the shape of this inner cavity is obviously much better than the inner cavity of several other shapes. ”

Chen Haitong said to Yang Jie.

Yang Jie nodded, and then said, "Take me to the fuel production line to have a look." ”

Then everyone accompanied Yang Jie to this solid rocket propellant production plant on the outskirts of the city.

The factory is located in a hilly valley, surrounded by security fences, barbed wire, and watchtowers, and is guarded by armed police.

Inside, there are warning signs calling for protective overalls, gloves and respirators.

Entering the workshop for pouring thick concrete, this workshop is a solid fuel mixing workshop, the workshop is neatly placed for mixing fuel components, its multiple rotating blades are placed in a very particular position, the sides of the blades will not come into contact with the mixture, obviously to avoid the risk of friction and sparks.

At the same time, there are also impassable mixing vessel equipment in the workshop, surrounded by heating and stirring agitators, and there are chutes on it, which can be filled with impassable items.

The mixing ratio and processing flow of these solid fuels, as well as the process parameters, are the secrets of Sinoking Aviation Technology.

This mixing process is very dangerous, so the whole workshop is treated with anti-static treatment, and different equipment is isolated from each other.

On the façade of another building, the mixed fuel is poured into the rocket engine casing, which is made of carbon fiber lightweight hollow tubes and lined with insulation, and these jelly-like mixtures are gradually poured into the rocket casing, while the middle of the engine casing is placed in a casting pit with a designed mandrel mold in the center.

This pouring process is naturally very particular, the temperature control during pouring, the control of the amount of mixture pouring and so on are to be explored one by one, otherwise there are bubbles in the pouring must shovel down the fuel again, and the fuel shovel down is also a very dangerous thing.

Because pouring pays attention to the principle of pouring, the extra solid fuel must also be shaped after pouring and curing.

The technology of plastic surface shaping of rocket solid fuel engines is a difficult problem all over the world and cannot be completely replaced by machines.

The strength of the technician's knife depends entirely on the judgment of the workers themselves, and the accuracy of the medicine directly determines whether the missile can achieve a precise range in the predetermined orbit, because the previous fuel particles are relatively coarse and the toughness is also large.

Moreover, solid rocket propellant is toxic, and it is an extremely dangerous type of work to shape solid fuel, and Huake Aviation Technology Company has also hired several solid rocket propellant carvers at a heavy cost, and these technicians are recruited from the aerospace corporation.

Compared with the solid-fuel rocket engine developed by Yihang Group, the fuel developed by Huake Aviation Technology Co., Ltd. uses the chemical growth method, and the metal fuel in it is ionized and adsorbed in the micron-level microsphere, so the particles are very uniform and the combustion is very uniform, and the rocket engine shell uses carbon fiber composite materials, so the difficulty of shaping is not too great.

And Yang Jie also acquired the German Festo production pneumatic products manufacturing company, this company has also been developing pneumatic bionic manipulator product technology, Yang Jie will acquire this company is also for his own company to produce a variety of pneumatic machinery and equipment, but also for Huake Aviation Technology Company to develop pneumatic manipulators to help carvers more efficient completion of solid fuel shaping work.

In the afternoon, Yang Jie also convened a meeting of the company's management.

"No one can guarantee 100 percent that a new solid-fuel rocket will have an accident, and I hope that everyone will find out the real cause from this accident and solve it. ”

Yang Jie looked at Geng Baochang: "When will this engine be tested?"

"Yang Shao, we are testing a new flexible baffle material, which has met our design goals, and the engine will be tested on the engine test bench again next week. ”

Geng Baochang said.

"Okay, I'm here for this time, and I must complete the target test of this missile as soon as possible, after all, the rest of the country is waiting for it in a hurry. ”

Yang Jie said.

"Yes, Yang Shao, we will definitely deliver the engine of this missile engine on time. ”

Geng Baochang said with a firm face.
