The older generation of scientific researchers who are idle in the imperial capital are actually big bulls, most of them are disembarked because of the project at hand, but they are high-end talents, and the country can't just leave it alone.

Transferring these talents to the major ministries and commissions of the imperial capital as consultants and engaging in some foreign academic exchanges, in general, is to spend a small amount of money to support these industry bulls.

The overall decline in national scientific research funding can also be understood by most of the older generation who understand things, including Chief Engineer Wu Daguan, who retired to the second line, although he did not participate in the development of specific models, but also studied the engine research and development process and national standards.

Engaged in theoretical work, the main thing is to explore and improve the soft power of the aero engine industry, usually in terms of time is very abundant, when receiving Wang Zhengguo father and son, the whole person is very energetic.

"Spey 202 engine, if you do have relevant plans, and the 430 factory is unwilling to cooperate, there must be no way, I have only been there for less than three years, and then after the project was launched, I was directly transferred back to the imperial capital, and the influence over there is not great. ”

For the 430 factory, Chief Master Wu didn't have much to say, and the big leaders in the ministry didn't have a clear attitude, so he didn't make sense to come forward.

However, seeing that Lao Wang, who was transferred to the ministry for the elderly like himself, still hasn't given up, and still has the ambition to start all over again.

Unconsciously, he still gave some suggestions: "As for the TF-41 engine you said, I know this, Rolls-Royce has a relevant plan, I was still in charge of Spey bench test in Rolls-Royce at that time, and I have also seen this model, do you confirm the idea of fighting it?"

The TF-41 afterburner model was proposed when the F-14 was renewed, and the time was almost the same as when the Spey 202 was introduced in China, and the two projects themselves have a great correlation, and it is not surprising that Chief Engineer Wu knows.

Since it is certain that he intends to take the TF-41 route, and he also wants to fight the idea of Chief Wu Daguan, the current situation is the best.

"Chief Engineer Wu, since we know the TF-41 engine, it would be great, we now need a high-thrust turbofan engine, and it must be with afterburner, so we have taken a fancy to this Spey overhauled engine, do you think it is necessary for us to introduce it?"

What is called is it necessary When Wang Zhengguo said this, he had already made a decision in his heart, but he just made a gesture in order to fool this experienced old engineer.

Fortunately, Chief Engineer Wu, the older generation, ate this set, and when he heard that he was going to prepare for the introduction of the TF-41 engine, he knew it: "Of course, this engine is the one with the largest thrust in the entire Spey family, and now the ministry is already preparing to talk to Luo Luo about buying TF-41 design materials, even if you don't talk about it, this time Luo Luo will come to the imperial capital, and the ministry will also talk about it." ”

Blinded, this time Wang Zhengguo he was blinded again, and the ministry also has a plan to introduce TF-41?

No, if the ministry really introduced this engine, then what is the reason why the last face to be localized is the 9-ton Spey 202, after all, the model with greater thrust can be more popular!

Wang Zhengguo was very surprised, and Lao Wang was also not exempt from vulgarity, so this time it was not Wang Zhengguo's turn to speak: "It means that China is preparing to introduce the TF-41 engine as a high-thrust military turbofan, and intends to use it as the power system of the new Jelder?"

Good guys, TF-41 belongs to the second generation of half-thrust turbofans, once this thing comes to China, it will be fine!

It's a pity that the situation doesn't seem to be as simple as imagined: "No, this time it's to buy a TF-41 without afterburner, as a technical reference for the gas turbine of Plant 430, and now the Spey 202 at hand in Plant 430 is changing to a gas turbine, and the power cannot exceed 10M, but the Spey gas turbine changed by the British can reach 14M, mainly because the British changed it on the basis of TF-41, not Spey 202." ”

Understood, this is a complete understanding of the situation, if it is really calculated like this, the 430 factory should indeed have the confidence now, and it can decisively refuse Wang Zhengguo's cooperation intention before, because people have not lost the trust of the army, and do you not see that the army and the Ministry of Aviation are still preparing to continue to burn money?

At this time, I remembered the turbofan 9B engine that was rumored to be designed for the J-7B after 2000, with an afterburner thrust of up to 11 tons, which may be supported by TF-41 technology, which is really interesting.

As for why the last Spey gas turbine was dismounted, it has something to do with the fact that this engine has a power of less than 10M, after all, if it is really this power, it is completely unable to meet the needs of domestic 052 series destroyers.

"Chief Engineer Wu means that this time China intends to purchase TF-41 technology to provide reference for Spey gas turbines, rather than developing a high-thrust turbofan on this basis?"

Chief Engineer Wu, who has been working as an aero engine technology consultant in the imperial capital, has participated in the whole process of TF-41 data purchase evaluation, and naturally has a clear understanding of this project.

He has been very sure: "No, the domestic purchase of TF-41 related information is only as a supplement to the Spey 202 project, in order to use it as a reference for Spey Airlines, and there is no plan to use it to develop military high-thrust turbofans, you must know that this thing is essentially a Spey modification." ”

The new J-1 engine that is required in China highlights the volley performance, and how to change the TF-41 engine at high altitude and high speed born from Spey, which is finally a very ordinary data, has suffered a loss on the Spey project before, and there is no reason to do it again.

But then again, the high-altitude performance of the engine is average, which may have an impact on volley operations, but for the South African program, this is simply made in heaven, which can guarantee ultra-low fuel consumption and high thrust, which is enough!

Needless to say, the father and son both understand that this time is really an opportunity, the TF-41 project must be obtained, if there is this thing, what else do you need 202, the gap between the two is too big.

"Lao Wu, you should also know that I recently have a military fighter project in cooperation with foreign countries, and now I can say very clearly that this project requires a high-thrust turbofan engine, and the positioning of the model does not need to consider the interception mission, mainly to highlight the medium and low altitude subsonic multi-purpose, do you know what this means?"

If that's the case, it's not that you can't resurrect Spey, anyway, you have to buy the TF-41 engine, it's better to contact Britain directly, and get the afterburner model they designed for the F-14 before, which will definitely meet the needs, and I believe it won't cost much. ”

In the final analysis, TF-41 is developed on the basis of Spey, and many technologies have been introduced through the previous Spey 202 project.

Wang Zhengguo had a new idea at this time, and said: "Before, the 430 factory said that they were busy doing the refueling of Spey Airlines, and there must be not enough manpower, I mean, the ministry should be able to hand over this high-thrust turbofan engine to our Shudu side to do it ourselves, right?"
