Chapter 1043

The climb rate of the fighter is also an important indicator. The higher the climb rate of the fighter, the faster it can get up. Whether it is a long-range interception or a sudden sneak attack on the airport, it is a very important indicator.

Mr. Lu said that his side would never cheat. This made Mr. Gu sound ugly and said, "Mr. Lu, you're wrong to say that. What's cheating? There are preconditions for the climb rate test. If you want to simulate the actual combat, then hang up the missile test, hang up the thunderbolt-11 and thunderbolt-8, add the auxiliary fuel tank, and then test."

Aren't you provocative? Let's talk about it.

Lu Lao didn't complain, but looked at J-11 with expectant eyes: "you must not humiliate us."

His eyes were like looking at his own children.

The progress of J-11 is quite fast.

The mapping of the airframe was completed last year. If it was only mapping, there was still a big gap in their own imitation. At this time, President Qin gave great help. I don't know where to get a batch of J-11 technical data. Relying on these data, their imitation progress was developing rapidly.

In particular, there are those test data. After understanding them, you can modify them on the original basis. For example, the tail engine of J-11 is replaced with your own Spey modified engine, which needs to be re matched. If you don't have these data, I don't know how long it will take to complete it.

Now, that's a familiar road.

They were fighting here. Suddenly, a voice came from behind: "our progress is not slow. The whole machine will come out so soon?"

Qin Guan has come. He just got off the helicopter and came straight here. It was a joy to see the brand-new J-11.

How do you think it's brand new? Look at the skin, of course.

The skin of the J-11 fighter has not been painted yet. It is the color of aluminum alloy. Of course, it is just in the factory state.

There are not half rivets on the skin. All of them are countersunk rivets. The appearance is quite smooth. Looking at the aircraft, Qin Guan felt a burst of joy. After this period of efforts, his side can finally imitate the male cat fighter. In the future, this aircraft will become more and more and become the main equipment of the Navy and air force.

When Qin Guan said this, they were both delighted. Old Chen hurried to meet him: "President Qin, our plane has come out. Have a look."

Old Chen looks like a primary school student who has scored 100 points and goes home to see his parents with his test paper. He looks at Qin Guan. For old Chen, Qin Guan is really like his parents. Qin Guan is the one who promotes the J-11 project.

Qin Guan nodded, "did we make this plane ourselves?"

Hearing Qin Guan's words, old Chen nodded: "yes, the main parts of the body are made by ourselves, including the most important wing box and rotating shaft of variable swept wing. Only this landing gear, our existing metal strength is not enough, so we use the accessories of Grumman company."

Whether the body can be made by itself is related to whether the aircraft can be really mass produced. It is like a sabbath of future generations. It can only tear down east walls to make up for west walls and maintain the male cat fleet by means of organ donation. Naturally, the number of fighters is getting smaller and smaller.

Most of the airframe is made of aluminum alloy and a few are made of titanium alloy. These are all made by ourselves. Only this landing gear is a difficulty.

Qin Guan understood the reason.

Because the male cat fighter was designed as a carrier based aircraft. When the carrier based aircraft landed, the impact force was very strong, so the landing gear should be stronger.

It can be said that when a land-based fighter is changed into a carrier based fighter, it needs to increase its weight by about 10%. Two important parts are the folding wing structure and the enhanced landing gear.

Old Chen imitated this aircraft and tried to be exactly the same. The avionics equipment and engine have been solved. On the body, the strength of the landing gear is too strong, and his side can't imitate it.

There won't be too many problems. After all, Han will not have an aircraft carrier for the time being. Before there is no aircraft carrier, Han's J-11 fighters will be deployed on land, and it's no problem to use the landing gear of the first strength.

However, Mr. Lu said so. After all, there are still defects. Mr. Gu on one side also came up: "it's not completely independently developed. Lao Lu, you're lame. Look at our fighters, but they are completely independently developed."

After hearing what Mr. Gu said, Mr. Lu didn't intend to interface, but Mr. Gu said in front of Mr. Qin that it was bad after all. Therefore, Mr. Lu also refuted: "are you independently developed? What about your engine? One of the three major parts is purchased."

Hearing Lu Lao's words, President Gu blushed and stopped talking, but Qin Guan was interested: "what? The J-8 used a foreign engine?"

"Yes, it's the rb199 engine," said Lu. "Their fighters use foreign engines, but foreign engines are really good."

Even Mr. Lu lamented that when the J-8 2 was replaced with the rb199, its performance immediately went up to a higher level.

What is the biggest disadvantage of j-8-2?

The use of two engines has greatly improved the power performance of the fighter, but at the same time, the fuel consumption has also greatly increased. When Qin Guan refuted, he said that the j-8-2 has a short empty time and a small operational radius.

Now, the backward turbojet engine is replaced by an advanced turbofan engine, and the performance of J-8 2 immediately rises. Just to say a little, the afterburner thrust of turbojet 13 is 64 kn, while the afterburner thrust of rb199 engine is as high as 75 kn!

In this way, the thrust weight ratio of the j-8-2 has been greatly improved, and the maneuverability has undergone earth shaking changes. Now the climb rate is compared with the engine. Although 6601 Institute has always said that the j-8-2 is a heavy aircraft, it is actually a real medium-sized aircraft. After the replacement, it is even more powerful.

Qin Guan remembered that when Niu Guoren came to promote rb199, he didn't care about it. He didn't expect that Gu Zong and they took the initiative to contact and started this version.

In addition to the power improvement, because the fuel consumption rate is greatly reduced, the operation radius is almost doubled, which is the advantage brought by the turbofan engine.

Hearing this, Qin Guan also became interested and said, "OK, actually changed the engine? Let's take a look at J-8 2 first."

In the past, Qin Guan was not interested in jian-8-2. Now he heard that Qin Guan was first interested in his own fighter. President Gu was even more happy. He immediately took Qin Guan with him and went straight to his own fighter.
