PS: The dismount of the flying leopard mentioned in the previous chapter is due to a variety of reasons, but this dismount is for better development in the future, and the new flying leopard will come out again, and it will be a new pneumatic when the time comes. The problem of the flying leopard is aerodynamics, which is personally admitted by the chief designer of the flying leopard, and is regarded as the biggest failure of the flying leopard, so it is better to get off the horse now.

Is there a problem with the idea of the Air Force, there is a KC130 from the United States that has passed the water before the interview, so naturally it stands to reason that there is no problem in changing the Y-8 to a tanker aircraft itself. So the platform used at the beginning of the tanker project in the previous life was Yunba, but why was Yunba eliminated in the end?

Because of a very simple problem, the Yun-8 aircraft is a transport aircraft, it is a turboprop-powered transport aircraft, the turbo slurry power is fuel-efficient, but it also makes the speed of the Yun-8 quite slow.

If it is a jet with good low-speed performance, there is no problem with the Y-8 tanker, but the biggest problem is that the low-speed performance of the J-8 in the republic's tanker is a scum.

This is also why the tanker aircraft was replaced with the H-6 platform in the last life, instead of insisting on the Yun-8 platform, and because the old guy J-8 was dragging its feet.

However, the current Air Force has not yet realized this problem, blindly seeing the benefits of the KC130, and imagining the excellent performance of the Yun-8 after it was changed to a tanker.

As for the problem of Yunba, it can be said that no one knows about it at this time, but Yang Hui knows about this big problem.

"Commander Zhang, I think there is a big problem in the design of the Yunba as a tanker, which makes it impossible for us to use the Yunba as a tanker. There's not even a way to fix this. ”

I don't know what this person sitting in the back does, but I heard that Yunba has a big problem with making a refueling machine, and there is no way to solve it. This is a bit surprising.

But then I thought that I used Yunba as a fuel dispenser platform, which has been studied for several years, how could there be problems, and when I was about to ask Yang Hui what the problem was, I couldn't sit still while sitting next to me and was responsible for the pre-research of the refueling machine project.

"Don't talk nonsense, you little comrade, this project. We have been arguing back and forth for two years, how can there be a problem, you have to pay attention to what you say. Don't go through your brain. ”

Without brains, Yang Hui is interested in this researcher who has not found a problem after two years of research, and he wants to see what this researcher has been studying for two years.

"Whether I said anything nonsense or not, naturally I understood immediately. Now I'd like to ask. The reason why you have been researching for so long to make the Yun-8 a tanker platform is to see the great success of the KC130 in the United States? ”

This is a surprise, I didn't expect this child to know KC130, a rare refueling machine, you must know that this refueling machine was originally produced less, and the appearance rate was low.

This researcher himself only knew about this tanker because he was engaged in a tanker, could it be that this kid really saw what was wrong, insider? There was some doubt in his heart, but this did not prevent this from fighting back.

"So what? The KC130 in the United States is the best proof of this. This is the same level of aircraft as our Y-8, and even the layout is the same. Of course, we should learn from foreign advanced experience in the development of refueling machines. ”

Learn from best practices? Is this advanced experience really that good to learn from?

"Learn from foreign advanced experience? Since that's the case, then there is a precedent for Bang Six to do refueling? The Soviet Tu-16 has a tanker model, and there are quite a few pieces of equipment, why do they use the Tu-16 as a platform instead of the An-12 as a tanker platform, have you studied it, the Soviets are not stupid at all? ”

Although it is not good to talk about the Soviet Union at this time, there is still no big problem when it comes to talking about technical issues.

Yang Hui's series of questions were indeed quite difficult to ask, and the entire conference room was stumped by Yang Hui's question, and it was really difficult to understand what the Soviets thought back then.

In particular, the Air Force originally supported the use of the Y-8, but at this time it also began to be a little skeptical, and in the argument for choosing the tanker platform, hundreds of pages of research materials did not seem to mention the problem that Yang Hui said, although the relationship with the Soviet Union is not good now, but the research and demonstration of the tanker aircraft. The Soviet tanker aircraft that have not been studied is indeed a loophole.

The commander of the Air Force looked at the refueling aircraft demonstration group that could not speak on the side, and he was angry, it was simply a bunch of rice buckets, and it was not good to conduct a technical demonstration, and it was too disappointing to hand over anything to these people in the future.

It's one thing to be disappointed, now let's listen to the reason of this little comrade: "Oh, what this little comrade said is quite reasonable, we are willing to listen to your opinions, and we will listen to them when you say it. ”

It is not only the commander of the Air Force who has such an idea, but also the commander of the Navy, Commander Liu, and the chief designer of the Xianyang Institute, who are interested.

The audience looked at Yang Hui, this time it was out of the limelight, Yang Hui didn't plan to make more detours at this time, there was no need to fight with the one just now.

"It's a simple question, whether it's Yunba or KC130, they all have a big problem: it's too slow. There is no problem in supporting low-speed aircraft refueling, helicopters, low-speed bombers, and attack aircraft with good low-speed performance are no problem, but there is no way to refuel second-generation aircraft that pay attention to high-altitude and high-speed aircraft in the air. ”

The research and development of military equipment must conform to the domestic situation, and the current use of the Y-8 as a refueling machine is completely inconsistent with domestic needs.

"If the maximum speed of the tanker is not as fast as the minimum controllable flight speed of the tanker, what is the use, our J-8 low-speed performance I believe that the leaders of the army know better than me."

Finally, when it comes to the problem of the Yun-8, it is also the problem of the KC130, which is quite serious in the republic. Of course, there is no such problem in the United States, and the United States refuels high-speed aircraft in the air with large jet-powered aircraft such as KC135 and KC10.

The status of KC130 in the United States is to use low-speed aircraft for air refueling, the most used is to use helicopters for air refueling, the flight speed of the helicopter is too slow, and KC130 must be used for refueling, which is the reason why this immobile air tanker has been in service until the new century, and even crashed one in Pakistan in 2000.

KC130 is a very successful tanker, but this success is based on the success of a very strict division of labor, if the Republic sees the success of the KC130, and intends to learn from the KC130, it will naturally be unadaptable, the Republic does not have a few helicopters, and there is no need for this thing at all.

The most suitable refueling aircraft platform can only be the H-6 bomber, only the H-6 bomber can achieve air refueling for the second-generation aircraft such as the J-8, when the Air Force of the Republic of China understood this, it had wasted a lot of manpower and material resources on the Yun-8 refueling aircraft project, and now Yang Hui encountered it must not allow this problem to happen again.

The leaders of the army understood this problem after thinking about it carefully, and the low-speed propeller transport aircraft is used to make tankers for second-generation fighters with poor low-speed performance, and they are afraid to think about it.

Thinking of this, the bigwigs of the Air Force did not have the courage to give a fierce look to the group of people who were responsible for the pre-research of the tanker project, which means that you waste will wait first, and then settle accounts with you after the meeting.

Since Yunba doesn't work, let's find another way, isn't there still a bombardment platform here? When the Air Force withdrew from the H-7 project, it is indeed time to compensate the Xianyang Design Institute.

After thinking about it, the organizational language, as it should be, I can't see the slightest appearance of supporting Yunba to make a tanker.

"I think what the Navy said is very reasonable, we should give the dismounted H-7 a compensation, so it is feasible to use the H-6 as a tanker platform, the experience of the Soviet Union in front of us still have to learn from it, Tu-16 is not all changed to a tanker, I think this plan is feasible. It's just that this fuel load is a bit low, which is a small flaw. ”

Just now, the two factions were still fighting, and now they are set up together to protect the H-6 as a refueling aircraft platform, which is really a living tragicomedy, and of course we should be more grateful to the Air Force for its spirit of correcting when it knows its mistakes.

At this time, when it came to the problem of insufficient fuel load, Yang Hui felt that he needed to mention the old thing again, and it seemed that there was a plan to change the H-6 to four engines, and maybe it could be put forward again.

"Perhaps, we can change the H-6, the fuel is not good because the engine is too fuel-intensive, plus the load is not much, two engines are not good, just add two more engines, make four engines" (to be continued......)
