The role played by the large air force in modern warfare is becoming more and more important.

Air supremacy is a prerequisite for an asymmetric war.

If China's Jian-7, Jian-6, and Qiang-5 were not as backward as they are now, the Chinese Xia Air Force would not have been able to rely on the bravery of "fighting bayonets in the air" and exchanged their blood and sacrifice for a decisive victory in the Battle of Nanding.

If our Jian-7, Jian-6, and Qiang-5 could surpass the Soviet Union's MiG-29, MiG-25, MiG-23, MiG-21, and Su-25, it would be impossible for our army mechanized units to inflict such heavy casualties in the Battle of Nanding.

Although the Battle of Nanding was fought, our army killed a total of 52,178 Annam monkeys, slightly and seriously wounded 268426, and captured countless prisoners. More than 200 T72, T62, T55 and other tank fighting vehicles of different models were captured, as well as a large number of AKM assault rifles, PKM heavy machine guns, SVD sniper rifles and other light and heavy weapons (excluding the Hongtong Gorge ambush), but no matter how big the fruits of victory, they could not restore the more than 2,000 heroic souls of our officers and men who were bloodstained in southern Xinjiang.

This is the price of backwardness!

If you fall behind, you can only be beaten!

Yang Weiping reminded himself in his heart all the time.

In the design of modern fighters, Yang Weiping is well aware that the first premise is to determine the thrust level, thrust curve characteristics and thrust-to-weight ratio of the engine. Because the comprehensive performance of the engine determines the design concept and performance purpose of the fighter.

The development, equipment, and performance indicators of military aircraft engines have a direct bearing on the national security and territorial integrity of a sovereign country.

The absence of suitable engine models of various series will inevitably have a fatal impact on the design and equipment of fighter aircraft, resulting in an incomplete and inefficient tactical system of the entire Air Force.

In the "Great Air Battle of Nanding," the various deficiencies of our army's air force are undoubtedly the best example of this.

And an excellent aero engine with advanced performance and reliability. It has the magic power to turn a fighter into magic.

The high-thrust military turbofan engine is the highest thrust level among all military aviation engines, and the development technology is the most difficult. At the same time, it is also the most core engine in the development of the spectrum.

High-thrust military turbofans have a direct impact on the development, equipment, and performance of twin-engine heavy fighters and single-engine medium fighters. This has a bearing on the formation of the Air Force's key tactical strengths, such as the struggle for air supremacy, medium-range interception, and long-range precision strikes.

The large-bypass ratio turbofan engine, which is improved on the basis of high-thrust military turbofan, is usually the preferred power for strategic bombers, strategic transport aircraft, and large civil airliners.

Chang'an City, the capital of Longxi Province, is the first aviation industry group in China. The location of the Engine Research Center.

256 top scientific research experts in aviation power, machinery and materials from different aircraft engine factories such as Shenfei, Hafei, Chengfei, Xifei, Guifei, Nanfei and Shangfei are concentrating on tackling key problems with the first engine core engine in China.

For the research of China's first engine core engine, Yang Weiping summarized many deficiencies and shortcomings in the development process of China's Taihang, Kunlun and Qinling engines in the previous life. At the same time, it provided multiple samples of AL31F, TF42 and F100 three foreign advanced turbofan engines for the core engine research group, which made the research team basically not take detours in the design and development process, and the efficiency was naturally extremely high.

Coupled with the substantial improvement of China's current aero-engine materials and precision machining capabilities, with the hard work and innovative spirit of the Chinese people in this era, and under the correct guidance and guidance of Yang University scientists, it would be a miracle in the world if this could not be achieved.

In the case of nothing. China's aviation research workers have independently developed the WS6 verification prototype on the basis of the AL21 turbojet engine of the Soviet Union and the Spey 202K turbofan of the British Rolls-Royce Company.

Nowadays, whether it is in technology, capital, manpower, materials, precision machine tools, high-precision machine tools, etc., there have been exponentially doubled. The first core machine named WS6 by Director Yang has started a number of pre-research and verification projects such as component verification, rotor verification, full-platform engine verification and durability verification.

Yang Weiping, wearing a laboratory white coat, is standing in front of a large computer display screen, looking at the ever-changing data and curves on the screen.

This set of large-scale computer-controlled aero engine ground bench test system, designed by Yang Weiping himself, is the most advanced engine ground test platform in Huaxia.

The engine placed on the test bench is hoisted and connected to the signal conditioning circuit through the sensor and level translation circuit, and then connected to the computer through the data acquisition device.

The computer mainly performs real-time performance calculations and real-time recording of test data, and displays data and curve oscilloscopes.

The test data is recorded in real time, mainly all the data sets generated by the simulation of the test process, which are displayed by the computer, and then the performance of each state is recorded, and the most common is the printout.

The system can measure 40 status and alarm signals at the same time, 54 numerical parameters, and the measurement error is less than 0.25%. At the same time, 52 engine performance parameters are calculated (converted) in real time, and whether the engine performance is qualified is judged.

All parameters can be displayed on the computer screen, and the key parameters can be oscilloscoped. A variety of display modes are used for different engine working states, and a variety of sampling frequencies such as 4 times per second, 2 times per second, 1 time per second, and 0.5 times per second can be selected, and it has the function of test simulation.

Ye Xiaoqiao also put on a white coat, standing behind Yang Weiping like a little nurse on duty, looking at the constantly beating and changing data information on the large computer display screen in front of her, she really felt very bored, but seeing Yang Weiping's preoccupied demeanor, as if these boring data were more attractive than her, it was so dedicated, so serious, and the faint excitement in her eyes was more excited than every time she made out with her.

This WS6 core aircraft is based on Yang Weiping's requirements for a twin-engine double-heavy fighter whose comprehensive performance should be on par with the F14 heavy fighter of the US Navy and Navy, as well as nine other military aircraft that cannot have combat functions.

In the selection of materials, the WS6 core machine adopts a large number of aerospace materials developed by China, such as ceramic matrix composites, carbon/carbon composites, high-temperature titanium alloys, intermetallic compounds, porous laminates, single crystal alloy blades, powder metallurgy discs, etc.

In terms of technology, the application of grazing blade technology, large and small blade technology, casting superalloy, blade casting forging, vacuum smelting technology, directional solidification and single crystal alloy and other first-class advanced technology in the current world. On the basis of the original WS6 turbofan engine, a great technical breakthrough has been made in the three core components of high-pressure compressor, combustion chamber and turbine.

Yang Weiping is indeed very excited and excited at this moment. He really didn't expect that in more than half a year, these China's aviation power experts in the engine research center drove China's first engine core engine.

The data displayed on the computer screen have fully reached the technical level of the third-generation core machine abroad.

The air flow rate is 35.5KG/S, the compression ratio is 11, the 10-stage axial flow compressor, the pre-turbine temperature is 1652K, the maximum diameter is 610MM, the thrust is 2455daN, the thrust-to-weight ratio is 7.8, the speed is 13450r/s, and the running time is 792 hours, 48 minutes, 31 seconds, 32 seconds, and 33 seconds......

With these data, it can already be determined that this WS6-H1 core machine can already be listed as a mature core machine.

The main way to serialize an aero engine is to change the main cycle parameters of the engine, such as pressure ratio, bypass ratio, air flow, turbine inlet temperature, etc., by changing the diameter and stage of the fan or low-pressure compressor and the cooling technology or material of the turbine under the condition that the basic geometric parameters of a mature core engine remain unchanged, so as to obtain engines with different performance and use.

By equipping the same core machine with different "low-pressure components such as fans, low-pressure turbines, afterburner and other related systems", it is possible to develop a series of engines covering a certain thrust (power) range with low risk. In order to meet the power needs of aircraft for different purposes, so as to achieve the multi-purpose goal of the core aircraft.

The development of a series of engines using multi-purpose core aircraft has always been highly valued by the developed countries of Western aviation, and has become the main technical way for the development of engine series.

Now, Huaxia's aero engine finally has a third-generation core aircraft!

"Very good! Chief Engineer Wang, in my opinion, this core machine can pass the test and be finalized!" Yang Weiping rubbed his palms vigorously and said happily: "We have taken a solid first step on the road of serialized development of China's aero engines! I must ask the party Central Committee, the Central Military Commission, and all of you for credit!"

"Director Yang, without you, there would be no WS6-H1 core machine!" Wang Chun, the former head of the WS6 project team standing on Yang Weiping's side, looked at Yang Weiping with admiration and said: "With this computer-controlled test platform, we can find many problems in the development process in time and anywhere, and then correct them." Director Yang, if you really want to say that you should be the first to take credit!"

"One fence with three stakes, one hero with three gangs. Wang Gong, if it weren't for you Huaxia Airlines people who have struggled for my country's aviation industry all my life, even if I Yang Weiping had the ability, I would not be able to get this WS6-H1 core aircraft out in such a short time. Yang Weiping said: "This is the crystallization of the collective wisdom and innovation of all 256 scientific research workers in the core machine project team! )
