Super Weapon Swap System

Hearing the other party's words, Qin Guan smiled: "Mr. Gerhard, we said this topic before. If you need it, we can export it to you after our research and development is completed, but if you want to develop it with us, please show your sincerity."

How do we know you're not here to cheat us of our development experience in stealth aircraft?

In international cooperation, everyone gets what they need. What if you deceive yourself by taking out all the technologies wishful thinking?

"Mr. Qin, of course we have technology, but we want to hear about the general changes you have made on this stealth aircraft, so that we can announce our plan to you," Gerhard said.

Qin Guan smiled: "well, let's first say, Tu Lao, you introduce them."

Hearing Qin Guan's words, Gerhard looked happy. At this time, Tu Lao took out a drawing from his briefcase. "This is the general drawing of the stealth improvement of our j-14."

Everyone was immediately pleased that this design drawing was the first stage of fighter design. If you get the design drawing, you can also get a lot of inspiration.

"To make the fighter stealth, the main thing is to reduce the radar reflection area," said tu. "we start with the nose and use the diamond nose, which is a compromise between the dual needs of aerodynamics and stealth."

In this era, the stealth aircraft that can be developed are polyhedral. It can be said that everything is for the purpose of stealth, and the ability of air combat is zero, while the Han country has begun to take into account the mobility of air combat.

"All interfaces are serrated, the cockpit cover is gold-plated, and the air inlet is S-shaped, which can avoid the exposure of the engine fan at the tail, which is one of the largest sources of radiation."

"On the rear fuselage, we use a double vertical tail with side tilt. The control of this vertical tail is particularly complex, so we must use telex operation in this direction to control it. After these upgrades, the cost of the fighter will certainly soar, but the combat effectiveness will definitely rise to a higher level."

Tu Lao almost followed the script. He just got this drawing from Qin Guan recently. For Tu Lao, when he got this aircraft, he was really very excited. Now, the visionary aircraft designers have begun to notice the great impact of invisibility on future air operations.

"Wait, you don't use a built-in bomb bay?" Gerhard asked.

If you want to be invisible, an important plan is to build a bomb cabin, so as to reduce the radar echo. After all, missiles and pylons are also a great source of radar wave reflection.

"No, if we improve it to the built-in bomb cabin, our fighter needs to be greatly improved." Tu said: "we are a light aircraft, and there is no space for built-in ammunition. If we want to change it, the body will have to be enlarged a lot, which is equivalent to redesign. The engine power will not be enough, and we have to find a new engine. In short, such a change is not worth the loss."

"Then the stealth performance will not be good."

"We adopt the belly semi buried design. On the pylon of the wing, we also use the modified pylon to reduce the reflected radar wave as much as possible." Tu Lao continued: "this is a compromise. After all, if it is launched from the bomb cabin, the complexity of the system will increase greatly."

It is not easy to launch the missile from the capsule. It requires a complex ejection mechanism to eject the missile. When eagle was engaged in F22 fighter, it was successfully developed after many failures.

It can be said that it is easy to modify the shape of the aircraft, but it will greatly increase the difficulty to change the structure.

"In this case, the invisibility can't reach a perfect level," Gerhard said. Obviously, the design of Han country is somewhat perfunctory.

"It depends on the design goal of our fighter," Qin Guan said "If we pay full attention to stealth capability, we can ignore others at all. In this case, we can focus all our attention on stealth and reach a good level. However, as a fighter, it should take into account the air combat capability. Even if we design complex missile compartments, missile launch of missile compartments and missile launch of pylons, it should be at least a few seconds later In an air battle, these few seconds may matter. "

Qin Guan was right about that. When the missile was launched from the pylon, it would fly out. If the belly bomb compartment was opened, the missile could be launched. The missile could not be ignited until it flew out. The steps were cumbersome and increased uncertainty.

In a few seconds, the other party may launch first.

"Moreover, by adopting this design, we have greatly reduced the probability of being found. If the previous j-14 fighter could be found 60 kilometers away, it may only be found 10 kilometers now. Ten kilometers is a visual distance. Our fighter won't always move in the dark. During the day, these ten kilometers are nothing ? "Qin Guan said so, and the other party nodded. Indeed, Qin Guan's analysis is reasonable.

"Well, we're finished. Please also introduce your progress in stealth fighters."

"OK, I hope you keep it a secret. We come to seek cooperation with you in good faith," Gerhard said. "In our country, a project called firefly is being launched."

Qin Guan was immediately delighted. These Hans were really sincere. Did they say their confidential items?

On second thought, it's nothing. After all, we also introduced our stealth aircraft project. Although the other party has approved the project, their aviation industry is incomplete over the years. It's too difficult for them to develop a fighter independently. It would be much better if they developed it jointly with the Han country.

"Our design belongs to a stealth fighter with polyhedron shape, but it is very different from your design idea. This aircraft will be an air control fighter focusing on medium-range interception ability, which uses excellent frontal stealth ability to attack enemy non stealth fighters outside sight distance."

The other party didn't lie. He introduced the other party's project and provided you with a design sketch. From this figure, this aircraft adopts tailless delta wing, single vertical tail and abdominal intake layout. Its cockpit and front fuselage are perfectly integrated. Although it is not exactly the same as the F-117, its design index is actually higher than the F-117.

According to the information disclosed later, the RCS (radar reflection cross-sectional area) of "firefly" is twice lower than that of F-117.

Listening to Gerhard's words, Qin Guan said, "that is to say, the fighter you designed is like an ancient Archer, who puts arrows from a distance?"

Harold nodded.
