Reborn in Hong Kong: The Tycoon Grows Up

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

At this time, old William said with a smile: "Junior is really amazing. He is actually more familiar with this engine than me."

He knew what Old William was thinking, so he didn't particularly care. You can tell from old William's expression that the old boy feels very uncomfortable. We will guard against the Heiyun Group during future cooperation and will inevitably launch an internal self-examination.

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

Bao Zixuan made a few operations, and a runway appeared on the screen, and the plane he had just designed was parked on it. It is very similar to the video games of later generations, but people today feel very strange when they have seen this.

At this time, the two Dickinson sisters were staring at the screen. The shock that the computer brought to them today was too great. No wonder Heiyun products are selling well all over the world, their performance is so powerful. It feels like watching a science fiction movie, and even some science fiction movies dare not act like this.

With the press of the 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 we don’t catch up, we may not even have the chance to cooperate in the future.

The insufficient thrust of the F404-GE-400 engine begins to show. Supersonic speeds can only be achieved when afterburning is turned on. Supersonic cruise cannot meet the design requirements at all. You must know that the aircraft cannot maintain the afterburner state for a long time.

At this time, fighter jets can only cruise at subsonic speeds, which is subsonic cruise at the highest efficiency. To go supersonic, additional fuel must be injected at the exhaust port of the engine. The increase in thrust is called afterburning, and the combustion chamber that injects additional fuel is called an afterburner. Turning on afterburner can enable the aircraft to gain great kinetic energy in a short period of time, improving the speed and maneuverability of the aircraft; however, turning on afterburner consumes a lot of fuel. Even a modern fighter jet will only have enough fuel if the afterburner is fully turned on. It lasts for several minutes, so the pilot will only turn on the afterburner during a few minutes of air combat.

Seeing the soaring values ​​on the screen, Bao Zixuan said with a smile: "The F404-GE-400 engine still has many problems with its thrust, and it is currently unable to achieve supersonic cruise. However, the overall performance is not bad. It seems that we need a more powerful engine." Powerful engine.”

Old William didn't know what to say when he heard that he was dissatisfied with the engine of McDonnell Douglas' flagship product. It's time to see what tricks this kid can do, and I've gained a lot of knowledge today.

Bao Zixuan: "We need a dual-rotor afterburning turbofan engine with a thrust-to-weight ratio of 9:1, which means the thrust must reach at least 100 kilonewtons. After the after-combustion chamber is opened, the thrust must reach at least 160 kilonewtons. And 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 currently on the market? But you can't look at this kid with ordinary people's eyes. He can always do some unexpected feats.

Future military fans must know that the engine Bao Zixuan is talking about is the Pratt \u0026 Whitney F-119 engine on the famous F-22 Raptor fighter jet.

The Pratt \u0026 Whitney F119 is an afterburning turbofan engine developed by Pratt \u0026 Whitney for the Lockheed Martin F-22 Raptor. This engine, with a thrust of 35,000 pounds (160 kilonewtons), is designed for supersonic flight (supersonic cruise) without using the afterburner. Compared with ordinary fourth-generation military aircraft engines, the F119 can output 22% more thrust with 40% fewer parts [1], and can perform sustained supersonic cruise at a speed of Mach 1.72. The F119 engine nozzle also uses thrust vectoring technology. The nozzle can deflect ±20° longitudinally, giving the F-22 better maneuverability.

Rolls-Royce, Pratt \u0026 Whitney, and General Motors are the three major aerospace engine giants in the world. Whether it is Boeing, Airbus, Dassault, Lockheed Martin and other military aircraft giants, engines are basically provided by these three companies.

Bao Zixuan is very familiar with Pratt \u0026 Whitney and General Motors, not to mention such an advanced engine. It is the first engine in the world to be installed on a fourth-generation fighter aircraft, which is of revolutionary significance.

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

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

The increase in engine thrust has brought qualitative changes to the aircraft. At least Old William was very satisfied with it.

After returning from the flight, Bao Zixuan said with a smile: "It can basically meet the requirements. We can also replace it with an engine with more advanced performance and see what the result is."

When they heard that the engine needed to be replaced, the two Dickinson sisters were just amused. But old William felt like he was dreaming, this engine was not good enough. As far as he knew, there was no similar engine on the market, at least not in the United States.

It’s hard to say whether Black Cloud exists, but aero-engine development requires a process. Although Heiyun has the super genius Bao Zixuan, 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 treat it as a joke. At most, it's just a few strings of data in a computer, and there's no need to invest real money in research.

Bao Zixuan: "First of all, the engine will adopt a three-rotor afterburning turbofan design, which can improve the engine efficiency; making the thrust-to-weight ratio reach an astonishing 11:1. The engine thrust must reach at least 122 kN, and the thrust will be 190 kN after turning on the afterburner .”

After saying that, he started to implant data, and old William didn't know what to say. This guy is really a bit arrogant. He has never seen or even heard of an engine with a thrust-to-weight ratio of over 10.

After installing the new engine, the aircraft's maneuverability has indeed been significantly improved. It only takes 600 meters for the plane to take off. This is a terrifying number and has great practical significance.

The aircraft performed various difficult movements in the air, all of which were clean and beautiful and completed in one go.

If such a fighter jet is really developed, there will definitely be no worries about orders, and even your military will pay for it. The Soviets were right around the corner, and no amount of money was as important as safety.

Bao Zixuan finally smiled with satisfaction, and 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 things that are unsatisfactory. And the ownership is not clear. After all, it was a joint design between the two of us. Now Senior William can watch me destroy all the documents, so Good for everyone.”

Hearing that Bao Zixuan wanted to destroy the design manuscript, Old William wanted to stand up and hit him. What do you mean, such a good aircraft, the design drawings are destroyed.

Old William: "It was jointly developed by the two of us, and of course the result belongs to both of us. Don't worry, I only want my share. As for who can develop it first in the end, and serve it in service, it depends on their abilities."

We can't let Bao Zixuan destroy such an excellent fighter jet. If we can get the design documents and technical parameters, McDonnell Douglas can save at least two years and at the same time save 300-500 million US dollars in research and development funds.

And who would believe it if he said it was destroying the design manuscript? The computer belongs to Bao Zixuan. There are probably few people in the world who are better at computers than him. After all, he is a prize winner.

Besides, so what if it was destroyed, it would have no impact 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 are not fully understood yet, I can only take a rough look at them.

It is no secret in the world that Bao Zixuan has a photographic memory. What's more, it's a product designed by one's own hands, so it's clear that you don't want McDonnell Douglas to get the design drawings!

In the previous life, McDonnell Douglas had developed this fighter jet, and if it was handed over to them, it would be returned to its original owner. But just giving it to him like this is obviously not the purpose of Bao richest man.

Bao Zixuan: "It stands to reason that since the senior has already spoken, 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 and unconscious young McDonald, Old William said with a serious expression: "McDonnell Douglas will pass on its research and development and production experience of the F-18 aircraft to Heiyun. It's up to you how much you can understand. ”

Old William understood that if the conditions were too low, people would definitely be dissatisfied. And in terms of money, I'm afraid no one in the world can make more money than him, so it's better to give him some benefits.

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