The next day, Yang Jie came to the missile production assembly workshop. (3) ≠ eight (3) ≠ eight (3) ≠ reading (3) ≠ book, .↗.o●

In the seeker production workshop, Yang Jie also saw the assembled tandem guidance head, with an infrared seeker in front and a small phased array radar in the back.

The IR seeker is mounted on a ring frame that can be adjusted to change the viewing angle of the IR detector.

In fact, Huaxing Group is also developing a micromechanical field of view selector that uses electronic control.

The IR seeker does not need to swing to add greater vision, but this technology is not yet mature.

The W-band phased array radar seeker developed by Huaxing Group is very compact, and it also makes a lot of space for the missile to install infrared detectors, and this phased array has about 700 small transceivers, which can track multiple targets and enhance the ability to carry out self-defense jamming against targets.

Liang Sihong, who is in charge of missile design, is a disciple of Academician Tang Jiyuan, the top rocket control technology in China, and a genius who came out of the junior class of the Chinese Academy of Sciences.

Thirty-six-year-old Liang Sihong was at the age of full energy at this time, and he was also constantly explaining to Yang Jie about missile technology at this time.

Seeing that so many devices were gathered together, Yang Jie opened his mouth and asked: "Is there a problem with the electromagnetic compatibility between these electronic instruments, and how to solve the problem of heat dissipation?"

The advanced active radar guidance system will produce a very large amount of heat because of the internal electronic components and power supply, and the outside will also produce heat, and the heat of the missile guidance cabin must be dissipated through the heat dissipation hole, and so many instruments and equipment and various electromagnetic signals, if the electromagnetic compatibility design is not good, many instruments can not work when they are turned on. ∈ 8∈8∈ read ∈ books, .≦.o≧

"In terms of electromagnetic compatibility, we have also done a lot of design, and we have also carried out various tests in various strong electromagnetic interference environments, and the results are still very good. ”

Liang Sihong paused and said: "The problem of heat dissipation is also the use of liquid nitrogen cooling, directly around the electronic components around several circles of stainless steel pipes filled with liquid nitrogen, in the test room, the infrared and phased array radar guidance system has been maintained at a temperature of more than ten degrees, in such a temperature situation, the computing speed of the entire guidance system can be maintained to the maximum." ”

Yang Jie carefully looked at the refrigeration pipelines distributed in the instruments and equipment, and nodded, many of Eagle Sauce's active radar guidance also use liquid nitrogen for heat dissipation.

The missile is on the launch frame of the fighter, because of the speed of the fighter, it will also rub with the air to generate heat, the heat dissipation system has to work when the fighter takes off, and the speed of this missile design exceeds Mach 4, the temperature of the shell of the missile will be higher, in order to avoid damage to the sophisticated electronic system inside, the use of liquid nitrogen cooling means is very ideal.

Because it is a dual seeker, the missile must be equipped with a high-performance data processor, intelligent chips, and micro fuel cells, and the heat emitted is not large, but the inside of the missile is a sealed environment, and if heat dissipation cannot be carried out, the internal electronic system will eventually be damaged at high temperatures.

The use of liquid nitrogen cooling method also solves this thorny problem.

Liang Sihong's design idea is to develop "strapdown" hardware and reduce moving parts to reduce size and improve reliability, while developing multi-mode seeker technology to enhance immunity to interference, and individual detector technologies to complement each other and improve performance.

When the missile is launched, active guidance can be used, and if it is interfered with in the operating frequency range, the passive mode of guiding the interference source can be used in the middle section, and the infrared guidance mode can be used in the terminal section.

Yang Jie nodded: "The company's focus at this stage is on the technology that can be used for air-to-air missiles, because air-to-air missiles have the most stringent requirements for the size and weight of the seeker, and these technologies can then be amplified and easily applied to other missiles." ”

Of course, the missile research and development department of Huake Aviation Technology Company will not only develop air-to-air missiles and air-to-ground missiles, Yang Jie naturally wants to expand these technologies to other countries, even if the military does not allocate research and development funds to the company, it will not be affected at all, and Yang Jie is not short of these money.

The development of these missiles was aimed at overseas markets, and it has already made a name for itself in two wars, leaving the impression that the company is a high-tech enterprise in the eyes of people all over the world.

The profits of the arms business have always been very high, and now Huake Aviation Technology Company has opened the UAV market, and the Eagle and Rainbow series UAVs have received more than 80 orders this year, and the revenue of the flight platform alone is 600 million US dollars, and the various precision-guided zhà dàn and missiles carried by the UAV are consumables, which are more profitable, and it is also a long-term stable meal ticket for the company.

The cost of UAVs of Huake Aviation Technology Co., Ltd. ranges from the highest-end Eagle UAV of 10 million to the cheapest Rainbow 3 UAV of more than 4 million US dollars, because the cost control is very effective, and the profit of the UAV can reach 40%.

Now more than 10 countries have placed orders for at least 200 aircraft to Huake Aviation Technology Company, and there are many domestic orders, and now the production line of Huake Aviation Technology Company has begun to produce at full capacity.

In fact, this profit is not high, in the previous life, Eagle Sauce was the blackest in selling weapons, and other countries purchased Patriot 3 missile systems, a total of four battalions, and the contract amount reached 10.5 billion US dollars, which is an extremely high price.

In the end, the official contract amount was halved to $4.5 billion, and the contract amount for Eagle Sauce to provide four battalions of Patriot 3 missiles to another country was reduced to $3.2 billion.

The purchase of the same size - four Patriot 3 missile battalions, this price from 10.5 billion dollars to 3.2 billion dollars, a drop of more than 7 percent!

This shows how black-hearted Eagle Sauce is in selling weapons, and how profitable anti-aircraft missiles are.

One of the most popular products in the international arms market is air defense missiles, and the number of Hongqi series seekers provided by Huake Aviation Technology Company to the Aerospace Group Corporation is also growing, and Yang Jie is naturally tempted by this market.

Yang Jie then also saw the two Immortal Bird long-range missiles provided by Anxiguo to Huake Aviation Technology Company, one of which was a heavy air-to-air missile with a length of four meters was also dismantled into parts.

The engine design department led by Geng Baochang also analyzed the solid fuel of this air-to-air missile, and Chen Haitong was also inspired to improve the solid fuel formula, and the performance was 40 percent higher than that of the engine of the immortal bird. 11
