F119 is an advanced twin-rotor afterburner turbofan engine developed by Puhui Company for the fourth generation fighter of the United States, and its design objectives are: supersonic cruise capability without afterburner, unconventional maneuvering and short take-off and landing capability, stealth capability (i.e., low infrared and radar signal signature), life cost reduction by at least 25%, number of parts reduction by 40~60%, thrust-to-weight ratio increase by 20%, durability by two times, and part life extension by 50%.

As far as Yang Weiping knows, it was not until September 1983 that the US Air Force awarded both Pratt & Whitney and General Electric a 50-month 50-month contract for a $200 million each.

That is to say, the US imperialists have not yet established a project on the F119.

The new technologies adopted on the F119 mainly include: three-dimensional viscous impeller design method, integral blisk structure, high turbulence strong swirl main combustion chamber head, floating wall combustion chamber structure, high and low pressure turbine steering reversal, integral afterburner design, binary vector nozzle and third-generation double redundancy FADEC.

In addition, the third-generation single crystal turbine blade material with a temperature resistance of 1070~1100 °C, a dual-performance heat treatment turbine disk, a flame retardant titanium alloy, a high-temperature resin-based material encore casing and some static structures with ceramic matrix composites or carbon-carbon materials are also adopted.

Yang Weiping only knows these techniques but doesn't know why. However, this does not prevent him from using his great reputation in the field of global scientific research to fool experts and scholars who are inclusive and universal.

Previously, he successfully developed four engines, WS8 Kunlun, WS9 Qinling, WS10 Taihang and WS12 Taishan, and basically did his best. I want to improve on this basis. We must rely on the help of US imperialism.

For the design theory of F119, Yang Weiping still knows a little bit. However, how to develop the corresponding new materials according to these theories and make them into related parts is not within his ability.

During the development of the Y20B Global Overlord in cooperation with McDonnell Douglas, Yang Weiping worked closely with the two major engine manufacturers, Pratt & Whitney and General Motors, and successfully developed a high bypass ratio WS8B turbofan engine based on the WS8, which is the standard power engine of the Y20B Global Overlord.

With the help of Huaxia's multi-material application technology in high-thrust military turbofan engines, GM successfully achieved mass production of the F110-GE-100 engine at the end of November 1981, two years and three months ahead of the original history.

Pratt & Whitney, of course, will not work in vain, they are in the second half of the month when GM achieved mass production of the F110. The original F100-PW-100 has been upgraded and improved. Successfully developed the F100-PW-220 and achieved mass production.

It can be said that in the development of military high-thrust turbofan engines, Yang Weiping's cooperation with the United States is a win-win result that everyone is happy about. This also established his unshakable lofty position in the field of aviation power in the world.

Of course. While helping the US imperialists. The big brother of the USSR could not be left out in the cold either.

With Karenia threading the needle. Yang Weiping also pointed out the research and development direction of upgrading AL31F to AL31FN for the Rurika Design Bureau.

I have to say that in the two years that Yang Weiping has been developing the Y20B Global Overlord in Chang'an, he has conducted many comprehensive and systematic combing and summarizing of his knowledge of aviation materials, aero engines and aircraft design. Combined with the advanced technology of Europe and the United States that he did not master in his previous life. His achievements in the field of aerospace research far exceed the experience and knowledge accumulated in his last life for more than 50 years.

And he also found that his memory and thinking and calculation skills are also much stronger than in his previous life, and he feels that his brain is like a large database, and all the scientific and technological materials and literature he has seen in his previous life can be remembered clearly.

Despite this, Yang Weiping still knows very well that with his personal ability and the financial resources of Tiangong Group, he will not be able to build the F119 engine and the F22 Raptor battle motive.

In order to develop the F22 fighter, Lockheed summoned a total of 1,000 American companies to form the Raptor Development Group, and cooperated with the US Air Force for more than 10 years before the F22 was mass-produced. The cost is astronomical.

Although Yang Weiping does not know much about the internal structure of the F22, he has a comprehensive and systematic understanding of the J-20 developed by Huaxia.

It may not be possible to build a real F22 now, but it is still possible to design a verification machine with a similar appearance to the F22 on the basis of the upgraded WS10C with two WS10 Taihang engines to fool the United States.

The reason why he decided to throw these two major baits to fool the US imperialists, Yang Weiping's purpose was to use the powerful industrial base of the US imperialism to create a brand-new world-class aviation industrial base in northern Burma.

After Rams sent Sir Young's intention back to China, Pratt & Whitney and GM immediately organized an elite team to arrive in Mandalay three days later.

At this time, Yang Weiping had already started a seminar on the theoretical feasibility of the fifth-generation high-thrust military turbofan engine and the fourth-generation fighter jet at the Myitkyina 01 Aviation Base with Song Wencong, Gan Xiaohua and other young aviation power talents.

By the time the project team composed of Pratt & Whitney and General Motors arrived at Myitkyina 01 Air Base, it was already the afternoon of April 25.

With Yang Weiping's work style, of course, he will not pay attention to seniority according to seniority. He made full use of his authority and prestige in the field of Huaxia aviation power research, and basically got all the aviation power talents who he knew about and were still very young, and all of them were brought to Northern Burma.

Aviation experts such as Song Wencong and Gan Xiaohua are still in their twenties and less than thirty, and no one in China pays attention to them at all. That is, Yang Weiping knew their development potential and summoned them all to his scientific research team.

In order to fool the American aviation power experts, Yang Weiping seized the time to draw out the three views, renderings, and aerodynamic layout drawings of the fourth-generation stealth fighter he named the F22 Eagle Falcon, and marked the specific relevant parameters.

When the project team jointly composed of Pratt & Whitney and GM saw the new concept fighter designed by Sir Yang Da, they couldn't help but be deeply impressed by the imagination of the Chinese people.

F-22 "Eagle Falcon" fighter, the total length of the fuselage is 22 meters, the wingspan is 16.7 meters, the height is 5.05 meters, the maximum take-off weight is 31 tons, the range is 4000 kilometers, the maximum speed is Mach 2.2, it can maintain 1.6 times the speed of sound cruise, the fuselage is made of 35% carbon fiber composite materials, and a large number of titanium alloys and composite materials are used.

The weapon loading uses a built-in weapon compartment, which can greatly reduce the external wind resistance, and the material is carefully designed with aerodynamic forces, so the F22 Eagle Falcon has a very strong climbing ability in theory, with a design maximum vertical climb rate of 360 meters per second and an instantaneous hovering angle rate of 30 degrees per second.

The F-22 has a twin-tail, twin-engine, single-seat layout. The vertical tail slopes outwards 27 degrees, just on the edge of the general stealth design. The air intakes on both sides of the wing are installed under the wing's leading edge extension (edge wing), and like the nozzle, they are both designed to suppress infrared radiation, and the main wing and horizontal stabilizer adopt the same sweep angle and trailing edge sweep angle, both of which are trapezoidal planar shapes with small aspect ratios, and the blister-shaped cockpit canopy protrudes from the upper part of the front fuselage, and all weapons are hidden in four internal bomb bays.

The structure is designed as a comprehensive aerodynamic shape with a high trapezoidal wing and an integrated tail in the horizontal plane, including vertical tails with rudder that are widely separated from each other and inclined outward, and the horizontal stabilizer is arranged directly adjacent to the wing.

According to the design standards, the design of the fighter with a small reflective shape, radio wave absorbing materials, and the use of radio-electronic countermeasures equipment and low-radiation airborne radio-electronic equipment to equip fighters with a minimum radar reflective surface of about 0.005-0.01 square meters is designed. In the body plan, 12% of the proportion of thermo-processed plastics, 10% man-made fiber polymer composites. On the mass production machine, the proportion of composite materials used in the plan accounts for 35% of the whole machine.

The diamond-shaped section engine intake ducts under the wings on both sides are non-adjustable, and the cold wall intakes of the engine compressor are S-shaped channels. The engine has a two-dimensional vector nozzle with fixed sidewalls and an adjustable nozzle cross-sectional area, as well as movable upper and lower adjustment plates that can pitch at an angle of ± 20 degrees to deflect the direction of thrust.

Undoubtedly, this design scheme has aroused great interest among American aviation experts.

After repeated discussions, a conclusion was finally reached that whether it is Huaxia's WS10C, GM's F110-GE-100, or Pratt & Whitney's F100-PW-220, its maximum thrust and afterburner thrust cannot achieve the design power of allowing the F22 Eagle Falcon to cruise at 1.6 times the speed of sound and 2.2 times the speed of sound.

As a result, Yang Weiping took out the F119 design theory he sorted out in a timely manner, pointing out a correct research and development path for aviation power experts in China and the United States.

After throwing this extremely attractive topic to the aviation power experts of China and the United States, Sir Yang irresponsibly returned to the shopkeeper. The reason is very simple, he wants to go back to the capital of Huaxia to get married, and if he has any questions, he can call him.

At the same time that a large number of advanced aviation power manufacturing equipment from the United States were moved into the 01 aviation base, Yang Weiping boarded his Tiangong-1 private plane and flew directly north from Myitkyina military airport to the capital of China.

According to Yang Weiping's original intention, he wanted to give Qiu Fang a wedding first and then return to China to marry Ye Xiaoqiao, but Qiu Fang persuaded him and told him that she didn't care about this kind of formality. In addition, Qiu Fang also told him that he and Ye Xiaoqiao had held a grand engagement ceremony that attracted worldwide attention, if he married her first and then married Ye Xiaoqiao, where would the face of the Ye family be?

If the Ye family is offended to death, his foundation in Huaxia may be fundamentally shaken in the future. Because, Chinese people have always been the most face-conscious. For the sake of face, sometimes a lot of things can be given up.

The main thing is that Thu Phuong is now the director of the FBI of the Democratic Federal Republic of North Burma. This identity is extremely sensitive to the top management of Huaxia.

With a deep sense of guilt, Yang Weiping obeyed Qiu Fang's arrangement and embarked on a voyage back to China. (To be continued......)
