Super Weapon Swap System

Other designers present were also very excited. Yes, they recognized that they were applying the pneumatic layout of Eagle people's F22!

Of course, a simple application does not play a great role. After all, aircraft design is too simple if it can be imitated by looking at a shape. All countries will make it. There is no specific data. Even if the curvature of a radian is different, it will bring great changes in performance, and even greatly reduce the stealth ability. The whole shape is carefully calculated.

This is also the reason why Qin Guan was able to let the people of Xiong country come together for a meeting. Even if they wanted to copy, they couldn't copy. The shape of their own side here is to apply the eagle country. They go back to apply the eagle country, which is the same. As long as they don't give them the core data, it's enough.

"Mr. Qin, this shape looks very good!" Mr. Gu sighed.

In fact, they have also demonstrated what kind of shape to adopt. Of course, they also want to adopt the advanced layout. However, whether it is the J-15 or the j-20, it is not suitable for the layout of vertical takeoff and landing fighters. After all, these layouts are double engines, and there is no place to put lift engines. They are forced to be helpless. They can only catch up with the duck and get on the shelf, Apply Jacques 141. If you don't take the next step, you're afraid you can't go on in the future.

Although President Qin said it at that time, they didn't care. Now look, what President Qin said is F22. If President Qin made it clear to them at that time, they might really practice it instead of doing it on Jacques 141.

"Yes, this shape was designed by imitating the F-22 fighter of the eagle people." Qin Guan admitted directly and explained why he took it out so quickly.

The state of Han doesn't mind being said to be plagiarized. The Shanzhai ability of the state of Han is the most powerful. Besides, their appearance is the best. Why should I find another way?

"OK, let's look at the second one." Qin Guan clicked the mouse and switched to the second one. The first one is the three views and the second one is the structure diagram.

The lines are quite perfect and exquisite. You can see the things inside. Of course, the most important thing we pay attention to is the placement of the engine. This aspect is very similar to Jacques 141. In fact, the vertical take-off and landing of the F-35 is originally based on Jacques 141. Of course, there are similar layout schemes.

The rear part is the main engine and the front part is the lift engine. The bomb compartment is arranged in the middle of the two, which also leads to the compression of the space of the bomb compartment. When arranging some large precision guided bombs, they may not be able to put down, but can only be plug-in. However, this is also a necessary choice.

Compared with the change of Jacques 141, there are two more exhaust pipes on the inner side of the wing, which lead out the air flow from the compressor of the main engine and exhaust downward at this part. In this way, we can more accurately control various take-off postures, which is like the control mode of harrier fighter. It can be said that we integrate various means.

"President Qin, this layout is quite good." dongdukov couldn't help praising: "The air introduction of the engine's compressor is just at the center of gravity, which can facilitate control, especially in the process of vertical take-off to horizontal flight, it can also provide a certain lift. It's a good idea. Just in this case, we have to change the engine again. I'm afraid our engine doesn't have this ability."

For a long time, the r79 engine of xiongguo has been used to support it, but now Tumanski Design Bureau has no intention to improve this engine, because there is no future, no funding, and the engine can not adapt without change. After all, the engine will always be the main factor determining the success or failure of a fighter R & D.

"We have our own engine," Qin Guan said. "Our turbofan-15 will be matched accordingly. This engine has a higher thrust weight ratio and is more suitable for VTOL fighters."

The r-79 is only powerful and has a large self weight. The thrust weight ratio is only about 56. The level of the second generation engine and our own turbofan-15 has reached the top level of the third generation engine.

"Mr. Qin, in this design drawing, I see that our lift fan is almost close to the pilot, which means that there is no space behind the pilot. I'm afraid we can't even put down the hydraulic mechanism in the cockpit." Mr. Gu asked again.

If you want to take off and land vertically, the jet air flow must be balanced. The Harrier's method is to put the engine in the center, the Jacques 38's method is to place it front and rear, and the rear and front work together, and the thrust center is just placed on the center of gravity.

Because the engine is at the back, the lift fan in front should be as front as possible. Only in this way can it balance front and rear. When it reaches the position of the cockpit, it is already at the front.

So, what about the cockpit mechanism?

The cockpit needs to have a turnover mechanism. The cockpit cover should be opened and locked at high altitude. At the same time, it should be thrown away when parachuting is needed.

Now, almost all cockpit covers are opened backward, and all kinds of devices are deployed behind the cockpit. Now if you want to do this, there is no space for the cockpit cover.

"The cockpit cover opens forward, just like the MIG 21," Qin Guan said.

The problem is solved in one sentence. Turn it over and open the cockpit cover forward.

That's what MiG-21 did in those days, but it was definitely not because there was not enough space in the back, but because it felt that if it was opened forward, the cockpit cover would stand up and give the pilot a shelter. After all, MiG-21 was the first aircraft that could fly to Mach 2. It was a difficult problem to shoot and escape at high speed. The Mach 2 airflow blew over, which was like a knife, It may cut the pilot's skin, and the cockpit cover can be protected by blocking in front of the pilot.

Unfortunately, this is just an idea. Due to the backward technology, there are multiple insurances on it. It is not easy to unlock all these insurances. The failure rate of MIG 21 ejection escape is very high, which is also called a living coffin. In the later stage, all of them are replaced with a backward opening structure.

Now it's different. The technology is developing very fast. What couldn't be mature before can be mature now. The F-35 has also become the only fighter to flip the cockpit cover forward. It is very different from others. In fact, it is easier for pilots to enter the cockpit after turning forward.

"These are secondary. The most important thing for this aircraft is not aerodynamics, stealth or avionics. The most important thing is flight control." Qin Guan said seriously.

Of course, these are important, but they can be solved. In terms of our current ability, it is not a big deal, but flight control is different.
