Although I also thought about changing the Z-8 helicopter in advance, it was still a little surprising at this time, and it was not until a week after the Army Aviation proposed to change the Z-8 to the Z-8, and it was really after seeing that all the characters of the three armed forces had arrived, which was considered to be settled down in my heart.

It seems that the country still has no intention of giving up the Zhiba, which has just improved, which is great news for AVIC Southwest, which at least means that Zhiba is still possible to reach a height that the previous plane did not reach after working hard.

It just so happens that now is the time to give a plan: "Regarding the major reform of Zhiba, we have been studying it for many years, and now we finally have a feasible plan, please take a look, leaders." ”

The projector hits the light and shadow on the screen,A helicopter that is so similar to the straight 8 also appeared in front of everyone's eyes,Although the shadow of the straight 8 can still be seen in the appearance,But the discerning person did see the shadow of the -101 helicopter from the inside。

With such a plan, Yang Hui dares to guarantee that he has never seen it in the previous face, when has Zhi 8 ever had such an improvement plan?

"Seeing this improvement plan for each straight 8, you don't feel familiar, as if you have seen it somewhere, right? Don't think about it, this Z-8 improved helicopter is a lot of reference to the design of the -101 multi-purpose helicopter, which is a scheme formed after long-term demonstration, and has been substantially improved compared with the previous Z-8. ”-

The 101 helicopter, as a multi-purpose helicopter with a maximum take-off weight of 15 tons jointly developed by Europe, was still in the midst of intense flight test work in 92 years, but it was also in a state of imminent service, but it was far from the requirements of the domestic army.

"What we need is not a helicopter with a maximum take-off weight of 15 tons like -101, but a multi-purpose helicopter with a maximum take-off weight of 12 tons, and the height of the fuselage must be reduced again, and it must reach a height of about 5.5 meters, only in this way can it meet the requirements of the army's new generation of destroyers."

5.5 meters, what kind of concept is this? Not to mention anything else, at least before that, the maximum height of the Super Wasp helicopter reached 6.6 meters, and this means that (8) ♀dǐng (8) ♀diǎn (8) ♀ small (8) ♀ said, .23.os_ (); With the current Straight 8 Demon modification, it is necessary to reduce the height of the fuselage by at least 1 meter on the basis of the original, is it possible to achieve such a requirement?

The answer is: Of course it is still possible, otherwise how can this be said to be a magic change.

The Z-8 project can be regarded as more than ten years in the 602 Institute, and the 602 Institute has not tried to reduce this guy's height, and this magic reform plan is definitely to go on this knife, otherwise it will not be easy to get on the warship in the future.

I have long had a design idea, and of course the answer is simple and pleasant: "We actually know that the straight 8 has the ability to take off and land on the water, which is the ability that many helicopters have, but the design time of the straight 8 is very early, and a lot of indicators have been given up for the take-off and landing on the water, and the special ship type bottom not only brings the disadvantage of high manufacturing costs, but also increases a lot of dead weight, but practice has proved that this design is not much needed now, so we choose to remove this huge ship bottom." ”

Removing the bottom of the boat type brought by the straight 8 from the French mother's womb is indeed a good idea, and it is also the route taken by the previous face when it developed from the straight 8 to the straight 18, so this design did not surprise Yang Hui, and the army also agreed with such an improvement, and even the navy felt that this ship bottom was unnecessary.

"Go on, removing the bottom of the boat can indeed reduce the weight of the aircraft, and even reduce the height of the plane, but this is still far from enough, you still need to use other methods to control the height of the helicopter."

In order to control the height of zhì Zhi 8, the navy is also heartbroken, but I just don't know if the new plan can meet the requirements, and even Yang Hui is not very clear at this time. But it doesn't matter, believing in the abilities of the technicians is the most basic quality you need to be a leader.

As for whether or not the predetermined design targets can be achieved in the end, this is actually not too important, as long as you are willing. Just like the British Navy, can't you also move a big guy like the -101 to a Type 45 destroyer? You know, it's just a guy about the same tonnage as Republic 052/.

But Yang Hui was obviously overthinking, and the next improvement plan directly pointed to the height control plan of the aircraft: "We want to straighten the bottom of the original 8 ship, which means that the original chassis part of the fuselage structure must be redesigned; Similarly, in order to meet the needs of personnel to get up and down quickly, it is also necessary to place large side sliding doors on the left and right sides, which leads us to redesign the fuselage structure on both sides. With such an improvement plan, we can completely control the height of the fuselage when redesigning, and 5.5 meters is not a problem at all. ”

The stage is called a fierce one,This is simply the lower body of the straight 8 completely redesigned,If such an improvement can't be called a magic change,Then I really don't know what the magic change is,The only problem is such an improvement plan,The amount of work will be relatively large,Time、Resources will cost a lot。

However, this is also obviously underestimating the determination of the three armed forces to change the magic to the straight 8, the army and the air force are interested in the large side sliding doors on both sides, while the navy is interested in the control of the height of the fuselage.

The three parties almost said in unison: "Okay, this plan is feasible." ”

Later, it is the improvement plan of the radar system of the Z-8, which is relatively simple: "The Z-8 was originally designed, and there were not many places to install radar, but since we redesigned the lower part of the fuselage of the Z-8, we naturally had to add a dolphin head, which can be used to place many radar equipment." If we want, we can even design the landing gear to be retractable, and that's fine. ”

After all, it is a redesign of the lower body of the aircraft, and many of the original shortcomings of the Z-8 can be effectively improved, even the power system.

From the 8th to the 90s, it was still not able to achieve 100% full localization, partly because the engine has not been completely copied, although the Super Wasp uses the Turbo 3 series engine in the 50s, but the situation is still the same, the reason is that the imitation of this engine is unknown, and there is no supporting design and research institute of the Lanxiang aero engine manufacturing plant nearby.

"In terms of power system, the straight 8 uses a turboshaft 6 engine, this engine is not only huge in size, but also has high fuel consumption, and the performance is completely backward in all aspects, so it is very necessary for us to use a new engine to replace it, so we chose the -2200 engine that has been pre-researched by AVIC Southwest. This engine was developed from the core of our S-4 turbofan engine, and is technically mature and reliable, and is expected to be developed within four years. (To be continued.) )
