Bao Zixuan is very familiar with the basic data of the F404-GE-400 engine. In less than a minute, the basic parameters of the engine are configured.

At this time, old William said with a smile: "My junior is really amazing, and I am more familiar with this engine than I am."

I knew what old William was thinking, so I didn't pay much attention. From the expression on old William's face, you can tell that the old boy is very uncomfortable. Heiyun Group will be guarded against in the future cooperation process, and internal self-examination will inevitably be carried out.

The GM F404-GE-400 is a very high-quality engine, but it is only for the third-generation machine. After installing the fourth-generation machine, the power output is obviously insufficient.

After Bao Zixuan operated a few times, a runway appeared on the screen, and the plane that had just been designed was already parked on it. It is very similar to the video games of later generations, but people who have seen this now feel very novel.

At this time, the two Dickinson sisters were staring at the screen, and the shock brought by the computer today was too great. No wonder Black Cloud products can be sold all over the world, and the performance is too powerful. It feels like watching a sci-fi movie, and even some sci-fi movies dare not act like this.

An enter key, the plane begins to taxi, and then takes off.

At this time, old William didn't know what to say. The gap between McDonnell Douglas and Heiyun was at least five years. If you don't catch up, there may be no chance for cooperation in the future.

The lack of thrust of the F404-GE-400 engine begins to manifest, and supersonic speed can only be achieved when the afterburner is turned on. The supersonic cruise, which cannot meet the design requirements at all, must know that the aircraft cannot maintain the afterburner state for a long time.

At this time, fighter jets can only cruise at subsonic speed, that is, cruise at subsonic speed at the highest efficiency. To go supersonic, you have to inject extra fuel at the engine's outlet. The increase in thrust is called afterburner, and the combustion chamber that injects fuel is called afterburner. Turning on afterburner can make the aircraft gain great kinetic energy in a short period of time, improving the speed and maneuverability of the aircraft; however, turning on afterburner is very fuel-consuming. Even modern fighter jets have only enough fuel if the afterburner is fully turned on. It lasts for a few minutes, so the pilot will turn on the afterburner only during the minutes of the air battle.

Seeing the soaring values on the screen, Bao Zixuan said with a smile: "There are still many problems with the thrust of the F404-GE-400 engine, and supersonic cruise cannot be achieved at present. However, the overall performance is not bad. It seems that we need a more powerful engine. A powerful engine."

Hearing that he was dissatisfied with the engine of McDonnell Douglas, old William didn't know what to say. When it comes to seeing what tricks this kid can play, I have gained a lot of knowledge today.

Bao Zixuan: "We need a dual-rotor afterburner turbofan engine with a thrust-to-weight ratio of 9:1, which means that the thrust must reach at least 100 kN. After the after combustion chamber is opened, the thrust must reach at least 160 kN. Binary thrust vectoring nozzles must also be used, so the engine should be able to meet the design requirements.

Old William was dumbfounded by Bao Zixuan, is there such an advanced engine on the market today! However, you can't look at this kid in the eyes of ordinary people, he can always make some unexpected feats.

Later generations of military fans must know that the engine that Bao Zixuan mentioned; that is the Pratt & Whitney F-119 engine on the famous F-22 Raptor fighter.

The Pratt & Whitney F119 is an afterburner turbofan engine developed by Pratt & Whitney for the Lockheed Martin F-22 Raptor. The 35,000-pound (160 kN) thrust engine was designed for supersonic flight (supercruise) without the use of afterburners. Compared with ordinary fourth-generation military aircraft engines, the F119 can output 22% more thrust with 40% fewer parts [1], and can carry out sustained supersonic cruise at a speed of Mach 1.72. The F119 engine nozzle also uses thrust vectoring technology. The nozzle can be deflected by 20 longitudinally, giving the F-22 better maneuverability.

Rolls-Royce, Pratt & Whitney, and General Motors are the world's three major aviation engine giants. Whether it is Boeing, Airbus, military aircraft giants including Dassault, Lockheed Martin, etc., the engines are basically provided by these three companies.

Bao Zixuan is very familiar with Pratt & Whitney and GM, not to mention such an advanced engine. You must know that this is the world's first engine installed on a fourth-generation fighter, which is revolutionary.

It was another operation, and the plane taxied and took off in one go.

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

The increase in engine thrust has brought qualitative changes to the aircraft, at least Old William looked very satisfied.

After returning from the flight, Bao Zixuan said with a smile, "It basically meets the requirements. We can also replace it with a more advanced engine and see how it turns out."

The Dickinson sisters were just amused when they heard that the engine was going to be replaced. But old William had a feeling of dreaming that this engine was not good enough. As far as he knows, there is no such engine on the market, at least not in the United States.

It's hard to say whether Black Cloud is there, but the development of aero-engines requires a process. Although Heiyun has the super genius of Bao Zixuan, but without a solid foundation, it is difficult to develop a military high-thrust engine.

But since this kid dares to bring it up, let's take it as a joke. At most, it is just a few strings of data in the computer, and there is no need to invest money to conduct research.

Bao Zixuan: "First of all, the engine will be designed with a three-rotor afterburner turbofan, which can improve the engine efficiency and make the thrust-weight ratio reach an astonishing 11:1. The thrust of the engine must reach at least 122 kN, and after the afterburner is turned on, the thrust is 190 kN. ."

After he finished speaking, he started to implant data, and old William didn't know what to say. This kid is really arrogant, he has never even heard of an engine with a thrust-to-weight ratio of more than 10.

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

The plane showed a variety of difficult movements in the air, and all the movements were clean and beautiful, in one go.

If such a fighter is really developed, it will definitely not worry about orders, even in your military. The Soviets were on the side, and no amount of money was as important as security.

Bao Zixuan finally revealed a satisfied smile, and he had a firm idea in his heart that this engine must be developed.

Bao Zixuan: "Although this plane has been designed, there are still many things that are not satisfactory. And the ownership is not clear. After all, it was designed by the two of us. Now Senior William can watch me destroy all documents, so that Good to everyone."

Hearing that Bao Zixuan was going to destroy the design document, Old William wanted to stand up and beat someone. What do you mean, such a good plane needs to destroy the design drawings.

Old William: "It was jointly developed by the two of us. Of course, the results belong to both of us. Don't worry, I only need my share. As for who can develop it first, and serve it according to their abilities."

Bao Zixuan can't be allowed to destroy such an excellent fighter. If the design documents and technical parameters can be obtained; McDonnell Douglas can save at least two years, and at the same time, it will save 300-500 million US dollars in research and development funds.

And it is said to destroy the design manuscript, who would believe it. The computer belongs to Bao Zixuan, and there are probably few people in the world with higher computer attainments. After all, they are the recipients of the prize.

Besides, even if it was destroyed, it would have no effect on Bao Zixuan at all. He was controlling all the designs just now, and he was just watching from the sidelines. Even the technical parameters have not been fully understood, UU reading www. uukanshu. com to see at most probably.

It is no secret in the world that Bao Zixuan has an unforgettable ability. What's more, it's a product designed by hand. It's clear that you don't want McDonnell Douglas to get the design drawings!

In the previous life, this fighter was developed by McDonnell Douglas, and it was returned to the original owner when it was handed over to them. But giving it to him like this is obviously not the purpose of the richest man.

Bao Zixuan: "It stands to reason that the senior has already said this, and both parties should keep a copy of the drawings. But this is unfair to Heiyun. I don't know what the senior thinks."

Seeing the drunk little MacDonald, Old William said with a serious expression: "McDonnell Douglas will pass on the research and development and production experience of the F-18 aircraft to Heiyun, and it is up to you to understand how much you can understand. already."

Old William understood that if the conditions were too low, people would definitely not be satisfied. And in terms of money, I am afraid that no one in the world can have more than him, so it is better to give some benefits.

It has long been seen that the Black Cloud Group will definitely enter the research and development of fighter jets. The F-18 fighter is definitely not weak, I believe Bao Zixuan will be satisfied.
