"What, it means that we will be equipped with Mi-17 helicopters in large quantities in the future, not in small batches like we are now. I said that you had served in the Black Hawk helicopter unit in the southwest before, and you should know the goods, and you also went to the last time you inspected the Mi-17, and you came back and said that the Mi-17 aircraft is not as good as the Black Hawk, now how are you?"

The one who originally led Yang Hui and his party over, after explaining the situation to the director in charge of equipment procurement, obviously caused a great shock.

And Yang Hui only knew at this time that this person had actually served in the Black Hawk helicopter unit, and even before that, he supported the Black Hawk and didn't look down on the Mi 17, why did he change his hexagram this time, this is so interesting, and now he is more and more interested.

And then, it was the moment to witness the miracle: "Although the Black Hawk helicopter has excellent performance, I do not deny this in the slightest, but the technical content of this helicopter is too high, and it is unrealistic for us to imitate such an aircraft in a short period of time, and coupled with the blockade of the United States, we can't even buy it with money." So I can only turn to the purchase of Mi-17, indeed, the performance of this helicopter is not as good as the Black Hawk in many places, but it also has a lot of quite good points, first of all, the procurement, use cost, and then the large size of the warehouse, which are much stronger than the Black Hawk. ”

Listening to these words, Yang Hui was quite supportive on the side, at least this one was fair and just when he looked at the Mi-17 and Black Hawk aircraft, so just looking at this diǎn, I knew that this time it strongly recommended the localization of the Mi-17, it must have been well thought out.

And then, the director of the equipment procurement department, who was still a little surprised, also came to the spirit: "Continue, what you said is quite reasonable, Mi 17 is indeed still a little excellent, but isn't its lack of diǎn also very obvious?" If we bring in this helicopter, it means that we will have to endure these annoying shortcomings for decades to come, how do you think this diǎn can be done? ”

What are the missing diǎn of m17? This is simply a lot, this aircraft itself is a combination of contradictions, and the advantages and disadvantages are completely two extremes.

"I understand that the lack of diǎn in the Mi-17 is too much, and there are indeed a lot of battle losses in the Afghan battlefield, but can't these be improved? As long as we put ∞dǐng∞diǎn∞ small ∞ say, .⌒os_. As long as we are willing to put forward improvement requirements, I believe that the localized Mi-17 will be more suitable for our national conditions. ”

As he was talking, he kicked Yang Hui here, and his intention was naturally obvious. And how AVIC Southwest can fulfill these requirements, and whether it can solve the inherent lack of diǎn in the Mi-17, this can only look at Yang Hui's table below.

After reacting, Yang Hui actually heard that he was going to introduce and localize Mi-17, and he had already begun to rectify the inherent defects of Mi-17 in a targeted manner, and put forward his own improvement plan.

"Do you have pen and paper? I need paper and pen. ”

"Yes, you sit here and I'll draw any ideas, and we'll all take a look."

As he spoke, he gave up his seat and let Yang Hui sit down and play to his heart's content, and what Yang Hui's improvement plan was, no one knows at present, and he can only see what the three views drawn by this guy look like.

As time passed, the office was silent, and only Chief Zhu was on the side carefully looking at what kind of plan Yang Hui was drawing, how it looked like a big change from the Mi-17 helicopter, no matter which side of the three views looked at, it was a little different from the Mi-17.

But I have to admit that the helicopter sketch on this drawing has a strong shadow of the Mi-17 helicopter plane, so this is indeed the improvement plan of the Mi-17, but this should be regarded as a big change, when the last stroke falls, it means that Yang Hui's plan is also on the paper.

When you put up the drawings and show them to everyone, you take a deep breath. As far as such an improvement plan is concerned, it can definitely be regarded as the improvement of J-7 to the level of J-74, which is a proper magic reform plan. However, if you can compare the J-7 and the J-74, you can know that this magic Mi-17 scheme must be a model that comprehensively makes up for the shortcomings of the Mi-17.

"For this solution, I call it Mi-17 for the time being, and it is also the one that I can think of now that is most in line with our capabilities."

Although this plan was launched by Russia in the new century, with the current capability of AVIC Southwest, as long as the Mi-17 was introduced and initially digested, it could be done in the 90s.

The first is to start from the door of the aircraft, directly pull out the Mi 1715 similar to the Black Hawk slide switch door design, change the previous unilateral small door knock appearance, plus the fuselage has been criticized behind the clamshell door to improve the springboard door.

After such an improvement, this aircraft has been greatly improved in combat efficiency, and the efficiency of personnel has been qualitatively improved, which is not inferior to the Black Hawk helicopter, and even the rear cabin springboard design directly makes the Mi-17 have airborne capability, which is essentially different from the Black Hawk's rope drop, but such a design needs to change the structural design of the body, which can already be regarded as a great improvement plan.

However, how could Yang Hui's improvement plan be so diǎn, and how could the subsequent Mi-175 iconic dolphin head be without? Not only can it play an excellent rectification role, but it can also be equipped with a large number of airborne equipment, such as weather radar, terrain radar, and even infrared radar.

Only after equipping the airborne radar system with a complete airborne radar system can the helicopter fly at night is possible, otherwise with the flight altitude of the helicopter, it will also be a night flight, and you will not even think about it.

"Yes, this has the meaning of diǎn, so the Mi-17 helicopter has been improved, but it can make up for many of the previous defects, but I see that the entire power system here seems to have been improved by you in the top view, tell me why!"

Top view, this is a heavy improvement made by Yang Hui on the Mi-17 helicopter, of course, it is also a necessary improvement, otherwise the size of the -2200 engine that was previously approved by AVIC Southwest cannot be interchangeable with the size of the B-117 turboshaft engine, and the size gap between the two engines is too big.

"If we want to complete the complete localization of the Mi-17, we can't ignore the problem of domestic power, and AVIC Southwest has a 2200 horsepower turboshaft engine, which is just right here. However, after comparison, we think that the engine deceleration device is more suitable to be placed on the side of the engine, which is completely different from the B-117 engine deceleration device used by the Mi-17 is installed directly above the engine, as for the layout of the deceleration device of these two engines, I believe everyone knows, so I don't need to be verbose.
