Zhang Haiping saw the electric lift fan surrounded by the huge receiver in front of him, with a diameter of one meter and a height of more than two meters.

He also deliberately climbed the ladder to carefully check the structure inside, this set of lift fans is intake from above, and there are compressors and high-power motors in it, which is quite complicated.

"How much lift can this set of lift fans provide?"

Shen Jianhong asked.

"The lift fan can provide nine and a half tons of thrust, and a servo system inside can deflect the jet forward and backward. ”

Wang Yonglin opened his mouth and said.

"Ah, how much thrust can you reach?"

Zhang Kelong asked in surprise.

"We have optimized the fan, compressor and motor technology to achieve such a high thrust with high intake and exhaust efficiency, combined with a high rotational speed. ”

Wang Yonglin said.

"It's a pretty power-hungry device, isn't it?"

Zhang Haiping asked.

"We use state-of-the-art power technology, using gallium nitride power amplifiers, which allow this high-power motor to work very efficiently, and our high-performance generator and battery system can meet the needs of the motor without overheating. ”

Wang Yonglin said.

Although it is easy to say, to achieve this extent, it is the technical strength that Huaxing Group has accumulated for so many years by continuously throwing money, people and equipment in these aspects for so many years.

Subsequently, everyone also saw several core prototypes of full-scale adaptive variable cycle engines developed by Yonghan Aviation Technology Company.

In fact, behind such a core prototype is the technical achievements of Yonghan Aviation Technology Co., Ltd., which has consumed dozens of engines and several years and tens of thousands of hours of continuous technical testing and verification.

Before the introduction of the digital prototype platform, Yonghan Aviation Technology Company really continued to use one prototype and one after another to carry out experiments to "burn out", which obtained a large amount of experimental data.

After the introduction of the digital prototype platform, the speed of designing the engine compresses the entire process, but it still consumes a lot of engines.

Then everyone also came to an experimental platform dedicated to testing this set of tail nozzles, in the monitoring room, you can see this set of vector nozzles in the simulated high temperature and high pressure flame flow constantly carry out various actions, like this test to continue to test and verify more than 1,000 hours, in order to ensure that this set of vector nozzle mechanism can work for a long time, to ensure that there will be no air leakage, resulting in fire and combustion.

Da Mao's Yak 141 equipped with a vertical take-off and landing engine in an aircraft carrier landing test flight, a prototype during the landing process was due to a problem with the flame of the engine during the landing process, which caused the fighter to catch fire, which also led to the project being shelved, and then because of Da Mao's economic difficulties, it never continued to develop.

For this type of fighter with VTOL capability, it is very suitable for landing on aircraft carriers and airfield runways where there is very short or no airfield runway, especially on light aircraft carriers.

Traditional aircraft carriers require a lot of manpower and financial resources to build, use, repair and maintain, and it is impossible for ordinary aircraft to complete just simple take-off and landing. If it is a sliding jump take-off, then the reasoning of the fighter itself must be large enough, if it is a catapult take-off, then the landing gear and keel of the fighter must be strong enough, in addition, there is also a blocking cable when landing, and the carrier-based aircraft also needs to be hooked when landing, and if it cannot be hung, it must be re-flown again. Whether it is for ships, fighters, and pilots, they need excellent strength.

However, vertical take-off and landing fighters can break this deadlock, and for some countries that do not have the ability to build large ships or aircraft carriers, light aircraft carriers equipped with this fighter have strong attack capabilities.

There is a famous saying in the aviation world that as long as the engine is good, bricks can fly. The reason why the aircraft can fly is undoubtedly all dependent on the engine, Yonghan Aviation Technology Co., Ltd. has caught up with the performance of the second-generation core aircraft through more than ten years of fierce pursuit, and has caught up with the level of the Eagle Sauce F119 aero engine, especially the temperature of the combustion chamber of the engine is higher than that of the Eagle Sauce engine, and it also has an advantage in terms of thrust.

This is mainly due to the fact that Huaxing Group has found a group of top material experts, and has also cultivated a group of technical teams, especially the calculation model established by Liu Fuping for the design of alloy materials has been done very accurately with the help of many scientists, and it is also the technology of artificial intelligence neural network, which can accurately predict the performance of a variety of materials designed, and realize the optimization of aging process and the control of material properties.

In fact, F119 is a more conventional design in the structural design, emphasizing simplicity and robustness, and trying to use mature technology to avoid high development risks and reduce manufacturing costs, in addition to the third generation of dual-redundant full-authority digital engine control system (FADEC), the system has self-testing, fault tolerance, fault diagnosis and processing capabilities, which further improves the reliability of the engine, and can determine the best parameters of the engine according to the integration of the aircraft drive system.

However, Yonghan Aviation Technology Co., Ltd. has made a great breakthrough in superalloy materials, so the temperature of the combustion chamber has been increased to more than 1800 degrees, and all the key components of the core aircraft have to be redesigned.

In order to make the engine reliable, we can only continue to carry out various experiments, work overtime, basically all year round, and develop the second-generation core machine according to the schedule.

The goal of Yonghan Aviation Technology Co., Ltd. is to keep an eye on the two aviation giants of Eagle Sauce, the goal is very high and the difficulty is very great, but these hard bones are gnawed down by the company's technical team one by one.

Over the past ten years, Yonghang Aviation Technology Co., Ltd. has squeezed into the first echelon in the aero engine business, the number of various engines produced every year in recent years has shown a continuous growth trend, last year the engine sold more than 1,500 units, the revenue of the engine business alone is more than 9 billion US dollars, if you add a variety of avionics and other businesses, the entire revenue has exceeded more than 14 billion US dollars.

Although Yonghan Aviation Technology Company does not make much money compared to other subsidiaries of Huaxing Group, the profits are still very considerable, and the income is very stable.

Because of the joint research and development of large transport aircraft and passenger aircraft by Damao and Zhonghua Fokker, many domestic airlines in Damao have also begun to purchase F150 passenger aircraft, and the number of F150 purchased by CIS countries is also increasing.

Yonghan Aviation Technology also has a large number of engine orders, and through large orders, the company is creating the conditions for sustained long-term revenue and earnings growth.

The engines ordered today are likely to still generate service revenue for the company two decades later, maintaining strong revenue and earnings growth.

Now Yonghan Aviation Technology Company no longer needs Yang Jie to invest a lot of money as before, and now this company can support the development of the company through itself, and also bring a steady stream of funds for Yang Jie himself.

However, Yang Jie still uses the money to invest in research and development, such as the vertical take-off and landing engine system is one of the projects.

It is this kind of high-intensity research and development that Yonghan Aviation Technology Co., Ltd. is making very fast progress on this project.
