There are more than 30 people in the Fengyun No. 4 team, the leader is Professor Wang Qingquan, and there is also an optical designer, a mechanical designer, and the team members are relatively young. Eight] Eight] Reading] Book, .2√3.¢o

After joining the company, the R&D team redesigned on the original basis, which is also the first time that China Satellite Communications Corporation has developed a large meteorological satellite in geosynchronous orbit, with a design weight of more than five tons and an estimated orbit of 36,000 kilometers.

After the technical team led by Professor Wang Qingquan joined, it was also redesigned on the original four-ton weight prototype, and many R&D technology centers at home and abroad under Huaxing Group Company undertook R&D tasks.

The number of R&D personnel of Huaxing Group exceeds 170,000, accounting for 60% of the company's employees, and it has a large number of R&D technology centers at home and abroad, so it can get a lot of technical support from overseas, which is much more flexible than the closed R&D system adopted by Aerospace Group.

The core instrument and equipment of Fengyun No. 4 is the multi-channel scanning imaging radiometer, and Huaxing Group Company undertakes the core component of this set of instruments and equipment - dual scanning mirrors combined with three-reflection optical system and gaze focal plane array detector.

During the imaging of this system, the east-west and north-south scanning mirrors perform linear scanning and step scanning respectively, reflecting the radiation from the earthscape to the main optical system, and splitting the incident radiation into visible light band, near-infrared band, infrared band, and ultraviolet light band through the relay optical system.

At the same time, the image processing software and hardware of this system are naturally undertaken by Huaxing Group Company, after all, Huaxing Group has very strong technical strength in this regard.

The camera is very delicate, the focal length is slightly not adjusted a little bit then it will be out of focus, the photo will be blurred, the working environment of the Fengyun-4 satellite is very harsh, the temperature difference is very large, all kinds of materials are thermal expansion and contraction, in such a large temperature range after the camera has long been out of focus, I don't know where to go. 】八】八】Read] book, .@.∞o

In order to solve this problem, Chinese people built an air-conditioned room for the instrument before, and used their superb temperature control technology to control the instrument at a temperature condition that is almost constant.

This time, Huaxing Group also used the materials and technologies on aero engines and rocket engines, and also created a constant temperature working environment for this set of equipment.

In addition, the Norwegian subsidiary of Huaxing Group also provides high-precision gyroscope and anti-shake technology.

This set of thermal radiometer in 36,000 kilometers away to take pictures, stability is the first, if the camera deviates by one arc minute, the earth is deviated by ten kilometers, so Huaxing Group to develop a set of dynamic compensation technology for this system, but also involves a large number of engineering and technical problems.

Song Xinyang saw that many of the components that had been developed were being tested a lot, and everything was going according to the plan in an orderly manner, and he nodded frequently.

Yang Jie originally wanted to stay in Yanjing for a few more days, but Huake Aviation Technology Company had a bào zhà during the development of air-to-air missiles, fortunately the test bench had protection and isolation measures and did not hurt anyone, but the engine test bench was burned down.

Hearing the news, he had to take a plane overnight.

A warplane is just a platform. It needs to have matching weapons and equipment to make the performance of the fighter play, otherwise, the fighter is useless.

The Jian-H-9 fighter delivered by the Hongdu Group Company to the country of rest is equipped with the Thunderbolt-12 air-to-air missile, which is a state-of-the-art air-to-air missile successfully developed by the rabbit country only last year, and an over-the-horizon air-to-air missile developed for the Rabbit Air Force and the Baba Yang Air Force.

However, now the production capacity of this air-to-air missile is insufficient, and priority must be given to meeting the domestic and Baba Yang air forces, and the air force of the rest country is aiming at the Tianlong 12 medium-range air-to-air missile independently developed by Huake Aviation Technology Company.

The rest of the country is very satisfied with the Tianlong 10 short-range combat missile of Huake Aviation Technology Company, but the range of this missile is only 30 kilometers, and the rest of the country is used to the immortal bird long-range air-to-air missile of country A, and they also hope that Huake Aviation Technology Company can develop a long-range air-to-air missile with a range of more than 100 kilometers to replace the immortal bird, and it is very happy to give research and development funds and pay a part of the deposit in advance.

However, the solid rocket engine is the technical shortcoming of Huake Aviation Technology Company, and the biggest technical problem this time is to appear on this.

The missile research and development department of Huake Aviation Technology Co., Ltd. is very powerful in the missile body including the servo, warhead and engine, as well as the front missile body and guidance system including the seeker, fuze, control rudder and power supply, but at this time it is stuck on the solid rocket engine.

Early the next morning, Yang Jie came to the solid rocket engine combustion laboratory building of Huake Aviation Technology Company.

The laboratory in this building has more than a dozen laboratories such as X-ray diagnostic research room, flow field diagnosis research laboratory, solid-liquid rocket engine test bench, high-precision small test bench, special fuel research laboratory, etc., and there are more than a dozen sets of experimental research and measurement and control systems, these equipment also cost tens of millions, and also hired more than 20 technicians, several doctors, and the others are basically graduate students.

At this time, the burned engine test bench laboratory was in a mess, and the technicians were cleaning it up, and the chief designer Geng Baochang, who was in charge of the solid rocket engine, was also ashamed: "Yang Shao, this accident is my dereliction of duty......

"Has the cause of the accident been found?" asked Yang Jie.

"We did an investigation overnight and found that the flexible baffle of the engine carbonized faster than designed, causing a blockage of the engine nozzle, causing the internal temperature of the combustion chamber to be too high, and as a result, it caused the bào zhà ......"

Geng Baochang, an engine designer in his forties, said that this was recruited by Huaxing Group from the Air-to-Air Missile Research Institute under the First Aviation Group Company, and he had also participated in the research and development and design of the Thunderbolt-12 and several other Thunderbolt series, and also had rich experience in this regard, and the Tianlong 10 air-to-air missile was his work.

However, Huake Aviation Technology Co., Ltd. wants to develop supporting missiles for stealth fighters and bombers, so it must develop smaller missiles, but the kinetic energy of missiles needs to be improved, so Geng Baochang has led the technical team to develop high-energy solid rocket engines in the past two years, and the result is that the engine bào zhà happened.

Yang Jie looked at Chen Haitong, the chief engineer of the propellant temporarily transferred from Zhongyuan Precision Machinery Company, and said: "How is it, how is the new fuel formula of the solid engine burning?"

Chen Haitong has rich experience in propellant propellants, and this time the solid rocket engine team encountered technical difficulties in the fuel formula, so Yang Jie transferred Chen Haitong and several technicians to work with the technical team to carry out technical research. 11
