Chapter 913

Baozixuan is very familiar with the basic data of f404-ge-400 engine. The basic engine parameters were configured in less than one minute.

At this time, old William said with a smile: "my younger brother is really powerful. He is more familiar with this engine than I am."

He knew what old William thought, so he didn't care much. Look at old William's expression. The old boy is very uncomfortable. It will prevent the black cloud group in the future cooperation process, and will inevitably carry out internal self-examination.

GM f404-ge-400 is a very high-quality engine, but it is only for the third generation. After installing the fourth generation machine, the power output is obviously insufficient.

Baozixuan operated several times, a runway appeared on the screen, and the newly designed plane had stopped on it. It is very similar to the video games of later generations, but people now feel very novel when they have seen this.

At this time, the Dickinson sisters are staring at the screen. Today, the computer has brought them too much shock. No wonder black cloud products can sell well all over the world, and the performance is too powerful. I feel like watching science fiction movies. Even some science fiction movies dare not do so.

With an enter key, the plane starts taxiing and then takes off.

At this time, old William didn't know what to say. The gap between McDonnell Douglas and black cloud was at least five years. If you don't catch up, you may not even have cooperation opportunities in the future.

The insufficient thrust of f404-ge-400 engine begins to manifest. Supersonic speed can be achieved only when afterburner is turned on. Supersonic cruise that can't meet the design requirements at all. You know, the aircraft can't maintain afterburner for a long time.

At this time, fighters can only cruise at subsonic speed, that is, at the highest efficiency. To supersonic, additional fuel must be injected at the outlet of the engine. Increasing the thrust is called afterburner, and the combustion chamber with additional fuel injection is called afterburner. Opening the afterburner can enable the aircraft to obtain great kinetic energy in a short time and improve the speed and maneuverability of the aircraft; However, if the afterburner is turned on, it consumes a lot of fuel. Even a modern fighter, if the afterburner is fully turned on, its fuel can only last for a few minutes. Therefore, only within a few minutes of air combat will the pilot turn on the afterburner.

Seeing the soaring values on the screen, baozixuan smiled and said: "there are still many problems with the thrust of f404-ge-400 engine. At present, supersonic cruise cannot be realized. But the overall performance is good. It seems that we need a stronger engine. "

Hearing that he was dissatisfied with the engine of McDonnell Douglas's fist products, old William didn't know what to say. I want to see what tricks this boy can play. I've gained a lot of knowledge today.

Bao Zixuan: "we need a double rotor afterburner turbofan engine with a thrust to weight ratio of 9:1, that is, the thrust must reach at least 100 kn. After the rear combustion chamber is opened, the thrust must reach at least 160 kn. Moreover, the binary thrust vectoring nozzle must be adopted, so that the engine should be able to meet the design requirements. "

Old William was bewildered by baozixuan. Is there such an advanced engine on the market! But you can't look at the boy with ordinary eyes. He can always do some unexpected feats.

Future military fans must know that baozixuan said the engine; That is the Pratt & Whitney f-119 engine on the famous F-22 Raptor.

Pratt Whitney F119 is an afterburner turbofan engine developed by Pratt Whitney for Lockheed Martin F-22 Raptor. This 35000 pound (160 KN) engine is designed for supersonic flight (supersonic cruise) without afterburner. Compared with the ordinary fourth generation military aircraft engine, F119 can output 22% more thrust [1] when the number of parts is 40%, and can carry out continuous supersonic cruise at Mach 1.72. The F119 engine nozzle also uses thrust vector technology. The nozzle can deflect ± 20 ° in the longitudinal direction, bringing better mobility to the F-22.

RORO, Pratt & Whitney and general motors are the three major aviation engine giants in the world. Whether Boeing, Airbus, Dassault, Lockheed Martin and other military aircraft giants, the engines are basically provided by these three companies.

Baozixuan is very familiar with Pratt Whitney and general motors, not to mention such an advanced engine. You know, this is the world's first engine installed on the fourth generation fighter, which is revolutionary.

It was another operation. The plane taxied and took off at one go.

After replacing the engine, the performance of the aircraft is not improved at all, at least it can meet the requirements of supersonic cruise. Of course, all this exists in theory and can only stay on the computer.

The increase of engine thrust has brought qualitative changes to the aircraft. At least old William is very satisfied.

After flying around, baozixuan said with a smile: "we can basically meet the requirements. We can also change to a more advanced engine to see the results."

Hearing that the engine had to be replaced, the Dickinsons just felt funny. But old William had a dream feeling that this engine was not good enough. As far as he knows, there is no similar engine on the market, at least not in the United States.

It's hard to say whether there is black cloud, but aeroengine R & D needs a process. Although heiyun has the super genius of baozixuan, it has no solid foundation. It is difficult to develop a military high thrust engine.

But since the boy dares to mention it, let's take it as a joke. At most, it is just a few strings of data in the computer without really investing money in research.

Bao Zixuan: "first of all, the engine will adopt the design of three rotor afterburner turbofan, which can improve the engine efficiency; This makes the thrust weight ratio reach an amazing 11:1. The engine thrust must reach at least 122 kn, and the thrust after opening the afterburner is 190 kn. "

Then he began to implant data, and old William didn't know what to say. The boy is really arrogant. He has never heard of an engine with a thrust weight ratio of more than 10.

With the new engine, the aircraft's maneuverability has indeed been significantly improved. It only takes 600 meters to make the plane take off, which is a terrible number and of great practical significance.

The plane showed all kinds of difficult movements in the air. All the movements were clean and beautiful at one go.

If we really develop and issue such fighters, we will not worry about orders, even in your military. The Soviets are nearby. No amount of money is as important as security.

Baozixuan finally leaked a satisfied smile, and he had a firm idea in his heart that he must develop this engine.

Bao Zixuan: "although this aircraft has been designed, there are still many unsatisfactory places. And the ownership is not clear. After all, it was jointly designed by the two of us. Now senior William can watch me destroy all the documents, which is good for everyone. "

Hearing that baozixuan was going to destroy the design manuscript, old William wanted to stand up and beat someone. What do you mean, such a good plane should destroy the design drawings.

Old William: "it's our joint research and development. Of course, the results belong to our two families. Don't worry, I just want my share. As for who can develop it first and serve in the end, it depends on their abilities. "

You can't let baozixuan destroy such an excellent fighter. If you can get the design manuscript and technical parameters; McDonnell Douglas can save at least two years and $300-500 million in R & D funds.

And who would believe that it was destroying the design manuscript. The computer belongs to baozixuan. I'm afraid there are few people in the world who have higher computer attainments than him. After all, they are the winners of the prize.

Besides, even if it is destroyed, it has no impact on baozixuan. He was controlling all the designs just now, and he was just watching. Even the technical parameters have not been fully understood. It's best to look at them.

Steamed stuffed bun Xuan has the ability to never forget, which is not a secret in the world. What's more, it's a product designed by yourself. It's clear that you don't want McDonnell Douglas to get the design drawings!

McDonnell Douglas has developed this fighter in previous generations, and it is returned to them. But giving it to him in this way is obviously not the purpose of Bao Shoufu.

Bao Zixuan: "it's reasonable to say that the senior student has said this, and both sides should keep one copy of the drawing. But this is unfair to heiyun. I don't know what the seniors think. "

Seeing the drunken little MacDonald, old William said solemnly, "McDonnell Douglas will transfer its R & D and production experience of F-18 aircraft to the black cloud. It depends on how much you can understand."

Old William knew that people would not be satisfied if the conditions were too low. And in terms of money, I'm afraid no one in the world can be more than him. It's better to give some benefits.

It has long been seen that the black cloud group will certainly enter the research and development of fighter aircraft. The F-18 fighter is definitely not weak. I believe baozixuan will be satisfied.
