"Yang Shao, our Director Zheng has put a lot of thought into it, and it has been a few all-nighters in the past few days, and the processing technology in our workshop has been continuously optimized and improved. ”

Kang Jianlong said to Yang Jie at this time.

After the processing of this batch of parts, the processing technology will be improved in combination with these problems, so that after the trial production and processing of three or five batches of parts, the process will be more and more perfect, more and more mature, and the processing quality of the parts will be better and better.

Over the past two years, Yonghan Aviation Power Technology Co., Ltd. has established this set of strict procedures at the beginning, and these rules have been formulated by Wang Yonglin.

Wang Yonglin has worked in Rolls-Royce for more than 20 years, and Rolls-Royce's incomparably meticulous work style has deeply penetrated into his bones, especially the company's production of high-end products such as aero engines, a little negligence will cause a major disaster, Yang Jie also fully supported him to formulate a variety of management rules that are almost strict and meticulously implemented.

These strict processes also ensure that the quality standards of the products produced by the company are very high, and the company's first batch of casing processing can reach such a degree, which also proves that the company's management and process flow are very effective.

This is what makes Yang Jie very happy.

The next day, Yang Jie also accompanied He Yongqing to visit and inspect the high-altitude platform experimental base of Yonghan Aviation Power Technology Company in Yongzhou.

Before arriving at the experimental base, a huge roar from the high-altitude test bench could be heard at this time, and various high-altitude experiments were being carried out at the same time in the two experimental cabins suspended in mid-air.

Zhou Zhenchao also introduced to Yang Jie and He Yongqing in detail the content of the two experimental cabins being experimented, and one experimental cabin was conducting an engine breathing test.

Another experimental chamber is conducting simulated high and low temperature start-up and altitude start-up tests.

There are many test items for the high-altitude platform, and at least six or more engines must be consumed after the complete test project, and the cumulative test time is more than 2,000 hours.

Only through a variety of complicated tests can the real performance and some defects of Hengshan aero engine be tested, and the performance of the engine can be continuously improved through subsequent modifications.

He Yongqing was also shocked to see such a large experimental base, so many people in the experimental base eat, drink, and Lazar, plus the non-stop experiment, which consumes a lot of funds every year, is a veritable gold-swallowing beast, and fortunately, this Yang Shao is too profitable, and he doesn't need to use the financial resources of his company to support this matter, and his personal funds can completely promote these things in accordance with the established goals.

A few days later, Yang Jie appeared at a test flight base in the south.

This test flight base has been carrying out test flights of many types of helicopters, and this time he was also invited by the military to participate in the test flight of Wuzhi 10 again.

After rushing to the test flight base, Yang Jie also met with several military bigwigs such as Zhang Haiping and Liu Jianqing.

Liu Jianqing has retired this year, but he is still concerned about the second test flight of Wuzhishi, and he also came here on purpose.

"Old Liu, are you okay?" asked Yang Jie with concern.

"I'm in good health. ”

Liu Jianqing looked at Yang Jie with a smile and said, "I heard that you have made a big move on the aero engine again?"

"All of this would not have been possible without the full support of the Chiefs. Yang Jie said with a smile.

Zhang Haiping said with a smile: "Comrade Xiao Yang, our military is now eagerly looking forward to your company being able to provide more advanced equipment for the military!"

This military boss has now taken over Liu Lao's position, he has met Yang Jie a few times before, and he has also made a lot of efforts in the matter of Huaxing Group Company entering the military supplier.

"Yes, I personally and the company will fully support the construction and development of national defense. Yang Jie nodded.

Zhang Haiping then asked Yu Feng, chairman of the board of directors of Changhe Aviation Group Company, and Du Changhai, chief designer of Wuzhishi, about the preparations for the test flight.

"Did the prototype of Wuzhi 10 make a forced landing last time?" asked Zhang Haiping.

"Vice Chairman Zhang, we have found out that the cause of the accident was the leakage of the cooling oil circuit control valve processed by Jinxing Machinery Factory, which caused the tail rotor motor to lose power due to high temperature. ”

Yu Feng said: "We have replaced the control valve of the cooling oil and it has been rigorously tested. ”

Yang Jie knew that in a test flight more than two months ago, when the two test pilots carried out the helicopter extreme rotor load test flight, the Wuzhi ten tail rotors lost power, the control was very difficult, and the altitude dropped rapidly, and the two test pilots relied on superb technology and extraordinary courage to drive the helicopter to avoid a number of residential areas in just a few minutes, and successfully forced to land in the rice field 20 kilometers away from the airport, holding the scientific research results.

Zhang Haiping looked at Chen Zhengfeng, the political commissar of the test flight team, and asked, "Are you sure about the test flight again?"

"Please rest assured that our test flight team is very confident in the performance of this helicopter, and will ensure that the maximum potential of this helicopter will be tapped and a large number of test flight data and flight outlines will be provided for the manufacturer's good combat troops. ”

Chen Zhengfeng puffed out his chest and said loudly: "Chief, the preparations are ready, and the test pilots are also ready." Test flights are ready for now. ”

"Test flight begins!"

Zhang Haiping, Yang Jie and others also came to the outside of the test flight site.

Not far away, a brand-new black-painted helicopter gunship parked in the helicopter hangar was slowly dragged out of the hangar by a tractor.

In everyone's eyes, the tractor dragged the helicopter slowly to the designated area, and then the tractor slowly left.

The volume of the gunship quietly parked in the distance is twice as large as the volume in Yang Jie's memory in his previous life, the nose part is hung with a spherical photoelectric pod, and a large black dome is on top of the rotor, which is very similar to the longbow millimeter-wave radome of the Apache gunship, and the whole is full of a sense of science and technology.

The radome on the head of the armed helicopter is the MIMO radar developed and produced by Huaxing Group, which is fundamentally different from the Apache Longbow millimeter-wave radar in the United States.

Over the years, Huaxing Communication Equipment Co., Ltd. has recruited a large number of communication experts to work the theoretical research and engineering technology of adaptive antennas, and has obtained a large number of technical patents in this regard, which are also used in their own antenna products.

In fact, as early as the end of the 70s of the last century, the integrated pulse and aperture radar developed by the French National Aerospace Research Agency and Thomson Company adopted the multi-input and multiple-output technology scheme of MIMO radar, and was verified on the experimental system.

This technical scheme adopts the transmitting antenna design of the radar with orthogonal waveform and sparse circular array, and transmits orthogonal frequency coded signals in all directions through each array element, so as to realize the omnidirectional irradiation of each antenna unit to space, and carries out relevant reception with the target echo through a direct wave at the receiving end, so as to realize the comprehensive pulse processing of the transmitted signal to form a coherent receiving and transmitting beam.

This kind of radar has the characteristics of high angular measurement accuracy, strong clutter suppression ability, high Doppler frequency resolution, high data rate, strong anti-jamming ability, and strong multi-target and multi-target tracking ability, but this kind of radar has a large amount of calculation, is not suitable for single-target tracking, and the waveform studied at that time is sensitive to Doppler frequency, which is not conducive to high-speed target detection.

Limited to the technical conditions at that time, this technology was only used as a technical reserve, and the progress was very slow.

However, after Yang Jie was reborn, he put forward this technical scheme, convened a large number of communication experts to study this technology, studied a large number of waveforms and phase coding, one-dimensional linear arrays and two-dimensional plane arrays, and personally wrote waveform coding algorithms and signal processing algorithms.

At this stage, Huaxing Communication Equipment Co., Ltd. is world-class in MIMO antenna radar technology, and is at the forefront of engineering technology implementation, and is used in its own company's communication equipment products, and is now shipping in large quantities.
