Chapter 109: T--30

Ling Shizhe looked at Jin Yong and his secretary, didn't understand their purpose, and just said lightly: "I am a general of the party-state, and the F-4 fighter is the important weapon of the country, and I have a great responsibility." ”

At this time, the two found out that the military uniform worn by Ling Shizhe was not an ordinary military uniform, but a general's uniform of the Kuomintang/Kuomintang/Party, and the epaulettes on his shoulders were the highest rank of generals in the army.

Jin Yong knew that Ling Shizhe's father Ling Zhigao was a national/democratic/party/lieutenant/general, and his father-in-law was also a national/democratic/party/lieutenant/general, but he didn't expect that Ling Shizhe himself was also a national/democratic/party/military/official, and his military rank was higher than that of his father and father-in-law.

Looking at the general's epaulette on Ling Shizhe's shoulder, and then thinking of the various technologies introduced by Ambrera Company to American-made fighters, and combining the two unrelated things, he immediately understood that the introduction of American-made F-4 fighter technology was a political task, otherwise he would not have been awarded the rank of general.

It seems that Lao Jiang attaches great importance to this young man and the F-4 fighter project! The two said in their hearts.

If Ling Shizhe knew what they were thinking in their hearts, he would definitely be crying and laughing, there was an emphasis on him, they obviously wanted to take advantage of him, I just wanted to play avionics, and they gave me the entire plane, how could it be like this.

Li Mengyao seemed to be an interesting person, and when she understood that this was a political task, she did not continue to ask, but changed the topic and said: "I heard that President Jiang proposed the name of your new company, can you let us know what the company is called?" ”

"China Aircraft Industry Corporation", an inscription written by President Chiang himself."

Jin Yong interjected: "Can I take a look at Mr. Zhong/Zheng's Mobao?" ”

"I didn't bring it out, I put it at home, Mr. Cha is free that day, you can go to my house and slowly appreciate the president's Mobao."

"Thank you so much, Ling Qishao."

"There, it's a little thing, don't thank you." Ling Shizhe knew that Lao Jiang could write well, and after he signed the introduction contract with McDonnell Douglas, he asked someone to find out if he could ask for a pair of ink treasures from Lao Jiang, but he didn't expect Lao Jiang to write this on the spot without saying a word, and Aviation Industry Corporation of China became the name of the new company.

In Ling Shizhe's previous life, if a company wants to use China's second son, it must be a state-owned enterprise, and other enterprises, whether private enterprises or local state-owned enterprises, cannot have the word China.

With Lao Jiang's inscription, Ling Shizhe will have a talisman in the future, no matter which side will not dare to touch him, but it is not a good thing for Ling Shizhe, why? Because the responsibility is too great.

Maybe Lao Jiang saw that Ling Shizhe was not very interested in airplanes, and saw that his purpose in building airplanes was just to sell his avionics equipment, and the airplanes were just a springboard for him to sell avionics, so Lao Jiang so happily agreed to nominate him for a new company, and his purpose was self-evident, hoping that he Ling Shizhe would not patronize himself to make money, but also pay more attention to the aircraft company, and give a Chinese prefix is to hope that Ling Shizhe can focus on the overall situation of China's aviation industry and revitalize China's aviation industry.

You must know that during the Anti-Japanese War, it was because China did not have its own aviation industry, so it was bullied so hard by the Japanese army, think about the bombing of Wuhan and Chongqing, Lao Jiang has been thinking about it until now, advanced fighters have always been a piece of Lao Chiang's heart, what is the level of Taiwan/Bay aviation industry, Lao Jiang is very clear in his heart, although there is no shortage of people with lofty ideals to revitalize China Airlines, but more are a group of insatiable filthy officials, coupled with various political constraints and power disputes, Lao Chiang knew that Taiwan/Gulf's aviation industry had no hope at all, but suddenly discovered that Ling Shizhe was interested in aviation, and in addition to the God-given opportunity that the United States was willing to transfer the full set of F-4 fighter technology to Taiwan, so regardless of whether he Ling Shizhe was sincere or false, Lao Chiang had a thought, that is, to develop a second aviation industry outside the system.

"China Aircraft Industry Corporation", Ling Shizhe is not a stupid person, as soon as he received Lao Jiang's inscription, he completely understood Lao Jiang's thoughts, and lifted a stone to shoot himself in the foot! Large aircraft are so easy to do, involving many industrial fields, cutting-edge and complex technology, beyond everyone's imagination, without the cooperation of a large number of third-party industrial companies, China's aviation industry is simply a joke.

Ling Shizhe's ideal idea is that Taiwan has introduced a full set of F-4 fighter technology, Ling Shizhe is responsible for the development of avionics, and installed it on the F-4 platform, don't look at the F-4 old, but in the fully computer-controlled F-4 fighter, Ling Shizhe is confident that its combat effectiveness can completely kill the flying leopard in the 21st century, the engine alone can not be compared to the flying leopard, what kind of engine does the flying leopard use? The Spey engine of the British Rolls-Royce company, this engine is only a civilian turbofan engine, the thrust-to-weight ratio barely reached 6, and the T-30 turbofan engine used by the F--4 Ghost heavy fighter, although it is at the same technical level as Spey, but he is a typical military engine, Bisby does not know how strong it is, T--30's reliability, durability, easy maintenance and easy maintenance are also much stronger than Spey, and the thrust-to-weight ratio is much higher than Spey's 6, close to 7.

Moreover, the T-30 engine has a typical future engine design idea in the United States on the engine, which has a significant production value for China's future engine design, and in the history of the development of aero engines in the United States, the T-30 engine, American engineers have tested the modular manufacturing mode for the first time.

The first prerequisite for the design of a modern fighter 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.

There are no suitable engine models for the individual series. It will inevitably have a fatal impact on the design and equipment of fighter jets, resulting in an incomplete and ineffective tactical system for the entire Air Force.

This. In later generations, the various deficiencies of our army's air force are undoubtedly the best examples.

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

The high-thrust military turbofan engine is the engine with the highest thrust level and the most difficult development technology among all military aviation engines, and 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.

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

The T-30 series engine is the first time that the United States has carried out modularization, generalization, and serialization of the experimental product on the engine, and do not think that the F-101 engine of the B-1 bomber is the first time to adopt this design, in fact, the T-30 series engine has already been tested in this regard long before it.

Although T-30 is an experimental product, it was born to shock the entire aviation community in the United States, and then the United States carefully examined the advantages and disadvantages of the T-30 series of engines, before formally establishing the technology and design standards of modern aero engines, and is on the basis of the core engine to develop a series of power models such as large thrust, medium thrust, small thrust, high ducted civil engine, turboshaft, turbo pulp, gas turbine, etc., this development model is the most efficient, the lowest cost development model.

The structure of the T-30 turbofan engine is completely different from the structure of the previous turbojet engine, and the T-30, like the British Spey, belongs to the first generation of turbofan engines.

The previous engines were turbojet engines, using the 1--1--0 support mode, that is, the ball bearing in front of the high-pressure compressor, and the rear fulcrum was located in front of the high-pressure turbine, that is, the high-pressure turbine was cantilever supported, and the load of the bearing was transmitted through the combustion chamber casing.

This design not only makes the engine bearing frame a large number, but also the high-pressure turbine due to the small shaft diameter of the bearing and the turbine disc is cantilever supported, which brings difficulties to the rotordynamic design, the earlier turbojet engine and Spey and the Soviet Union's Al-31 series engine are this support structure mode.

The T-30 is different, it uses GE's new 1--0--1 support method, that is, the rear fulcrum of the rotor is located behind the high-pressure turbine, and an intermediate bearing is used, that is, the outer ring of the bearing is fixed on the high-pressure rotor, and the inner ring is fixed on the low-pressure rotor.

This layout can not only reduce the load-bearing frame, but also the shaft diameter of the high-pressure turbine shaft can be made large, which increases the rigidity of the rotor, and its disadvantage is that the lubrication and sealing of the intermediate bearing are more complicated.

The famous F-119 and F-120 variable-cycle engines used in later generations are used in this structure, and even the J-2000 mid-thrust engine used in the EF-2000 Typhoon fighter is also used in this structure, and the improvement space of the 1--0--1 structure engine is much larger than that of the 1--1-0 structure.

From the above various comparisons, we can see that the T-30 turbofan engine is many times better than Spey.

This engine is so excellent that for a while, the new carrier-based fighter F-14 of the US military also replaced the F100-PW-100 with the T-30 engine as standard equipment, and it was not completely replaced until the F-110 engine was put into service.

Ling Shizhe never thought that the United States would transfer this excellent engine technology to China without reservation, although it is the Kuomintang/Kuomintang/Party, but in any case, it is the only two opportunities for China to get the advanced engine technology of the West, the first opportunity is naturally Spey, this technology was obtained by the mainland, and the second is T--30, which is now obtained by him Ling Shizhe.

However, Ling Shizhe didn't understand one thing, why in his previous life, Tai/Wan didn't get the technology of the T--30 engine? It was he who knew from Li Chunlai that the United States had proposed it to Taiwan/Bay, but Taiwan/Bay looked down on it and did not ask for it, after all, his performance in the Vietnam War was really poor, and he was completely pressed and beaten by the Soviet Union's MiG-21 light aircraft! In addition to the fact that there are not as many planes as in the United States, and the range is not as large as that of the United States, the F-4 was simply completely abused by the MiG-21.

Or is it simply that in his previous life, this kind of thing never happened at all, so Taiwan/Bay can't get the technology of T--30? But in this time and space, because his existence of Ling Shizhe changed history, so this happened?

What kind of situation is it, Ling Shizhe didn't figure it out, when he saw Jin Yong today, he wanted to ask Jin Yong if he knew it, after all, he was engaged in the media, and all kinds of news were very well-informed, if even he didn't know, then Ling Shizhe didn't know it.
