To be honest, it would have been a bit mysterious to complete the -2200 engine in four years, but since they have made up their minds to mobilize a scientific research and design team from the Ivchenko Design Bureau to participate in the project, it seems that four years is not impossible.

This time, when it comes to the magic reform plan of the straight 8, it also involves the improvement of the engine, and the entire three armies are the second monk who is confused, when did this come out of a -2200 engine, but it sounds like it is quite high-end.

Looking at each other, it's hard for anyone to say what's going on this time, but it's still very interesting to choose to continue to listen to what else to say below.

Chief engineer Shen of the Z-8 aircraft project on the stage continued: "According to the original design scheme, the Z-8 uses three 1500 horsepower turboshaft 6 engines, with a total power of 4500 horsepower. But with the newly designed -2200 engine, it will be a single 2200 hp engine, so with two you can reach 4400 hp, but we need to overhaul the powertrain. ”

With the development of time, the turboshaft engine in the early 50s is a little too old after all, although the turboshaft engine is not as fast as the turbofan start, but more than 30 years have passed, after all, it is still the Yangtze River back wave to push the front wave, which is the inevitable result of history.

Although it is only a cursory introduction about the -2200 engine, such an engine still arouses many ideas, and various voices have: "What engine are you talking about?" It seems that the army didn't know about this project before, right? ”

Although the army is very interested in the engine, it is obvious that Chief Shen does not intend to say more about this engine, which is due to the fact that Chief Shen himself does not know much about this engine, and according to the arrangement, after he reports the plan, there is also an arrangement for the 608 Institute to introduce this engine.

After comprehensive consideration: "Regarding the problem of the engine, there will be a special introduction of the 608 Institute later, I won't say much here, or continue to talk about the direct 8 modification in the power system, which is also very necessary." ”

Replace another slide and wait until the curtain clearly shows ♀the dǐng♀diǎn♀ ♀ novel, .2≧3.⊕os_ (); After the information, what everyone saw was what the power system of the new Z-8 looked like.

"The new powertrain is already very compact compared to the previous three turboshaft 6 engines, at least halved. The length of the turboshaft 6 engine of 2 meters is really huge, and it is still equipped with three engines, such a design is too backward, and the dǐng part of the entire helicopter fuselage is covered with engines and fairings, which brings strict aerodynamic drag and extra weight to the Z-8. The new power system chose to install two -2200 engines with a length of 1.5 meters, and we can effectively cut at least 500 weight, which is very necessary for a helicopter. ”

After all, the turboshaft 6 engine is too old, even older than the B-117 turboshaft engine, and the backward technology will inevitably be eliminated by history.

And now the military also seems to see what kind of project this magic reform is 8, which at least 50% of its design has to be re-demolished, and at the same time, people have to start thinking about whether this project is really necessary to support, the first thing to consider is the financial pressure, and the military spending over the years is really very tight.

Anyway, it's still Haihua: "The plan to improve the Z-8 looks more promising, but you yourself should also know how much risk this project needs to take, redesign at least 50% of the original design, which will cost hundreds of millions of dollars, and it must be more than this, the -2200 engine just mentioned is also still in the design, I think this project will definitely cost a lot of money, I have reason to believe that this entire project to be completed, at least 300 to 400 million yuan will be needed, That's right? ”

The Navy is roughly estimated at 300 to 400 million yuan, but this is far from enough, and the money can only be used for the research and development of the -2200 engine, the reason is that the current United Aero Engine Company is more and more in-depth research in the field of engines, and the clearer the understanding, the more understanding of how much testing is needed for the development of an engine, how much fuel is drunk, and how many prototypes are manufactured, which is very different from the early imitation of engines.

Of course, the turboshaft engine is small in power and cannot be compared with the turbofan engine, but it will not be low in terms of technical content, so the -2200 will also burn a lot of money.

"To say that the 300 million to 400 million is definitely not enough, to complete the improvement of the straight 8, we expect that it will take about 600 million yuan to be enough, but if the army is willing to contribute 400 million, the rest of the funds we can find a way to solve by ourselves, this is the approximate number we get after estimating, it includes the research and development costs of the engine."

600 million yuan, at this time, is still a considerable figure for the army, and even the development cost allocated to the J-18 before is only 500 million. Of course, that is because Southwest Science and Industry is willing to bear part of the R & D funds, and has not included the R & D costs of the engine.

But at this time, the Air Force is fully supporting the entire No. 10 project, and at the same time preparing to introduce the follow-up Su-27, and some of the support for the J-18, can still get the remaining money?

As for the Navy, there are also many projects in the current naval support, the J-18 is first of all a project that is enough to burn money, and the Navy of this plane also vigorously supports the large early warning aircraft project, as well as the new 7,000-ton missile destroyer.

In this case, can the above two branches of the military still come up with money? Anyway, Yang Hui won't believe it, just looking at the big black faces of the navy and the air force, I'm afraid that these two sides are going to retreat. Kindness! That's right, it should be like this.

The Navy has no money, and the Air Force has no extra funds to spend on the Zhiba Demon Reform Project this time, so this time it will depend on the arrogance of the big brother of the Army. I wonder if the Army will be able to provide enough funds for the project this time?

This should be regarded as the first time that AVIC Southwest has dealt with the army in an equipment scientific research project, which is really exciting!

That is, all of a sudden, the people in the entire conference room saw the army aviation coming here, and the first thing was the air force: "I think, your army aviation doesn't seem to have a large-scale military equipment research and development project in support, right?" The straight 9 is directly imported and manufactured, and it shouldn't have cost much money to make some small improvements now, so "

Feeling as if he was being stared at by something, the army aviation side was covered in a cold sweat, and after looking at the air force, he used his spare eyes to glance at the navy side again, and now it was okay, and at a glance, he saw that the navy's eyes widened, and it was obviously also (to be continued.) )
