Chapter 2462

Lu Lao's ideas were more advanced than one. When Qin Guan thought about these ideas, another explosive idea of Lu Lao immediately opened Qin Guan's eyes.

"The last thing to report is about the project of our stealth version of the J-11 fighter. We hope to approve it to enter the army in small quantities."

"Isn't it already in service?" Qin Guan asked. What kind of anti-ship missile did he want to use.

"It's not the j-11-b, but the real stealth aircraft. At present, it has no official military number. We hope we can call it j-11-c or J-15," Lu said.

Their stealth aircraft was the first to be built. When Mr. Song was still angry about the control system of the duck fighter, the fighter in their hands had taken off. Because it was originally improved on the basis of the J-11, it made rapid progress, but it was eventually dragged down by the problem of the engine.

Qin Guan's advice is to continue to test fly, accumulate experience, wait for the engine to mature, and then put into service in large quantities. Lu Lao and his team began to use the technology of this aircraft to improve the existing fighters and form a partially stealth J-11B fighter. Now, this fighter has been in service in large quantities, but the real fourth generation aircraft, Still in the test flight.

Of course, Mr. Lu is unwilling. After studying for so long, he can't finalize the design, and the cauliflower is cold. Therefore, now, Mr. Lu finally spoke out his voice while taking advantage of the arrival of Qin Guan. Should our plane also be in service? When will it be delayed? Get up early in the morning and catch an evening episode.

Song Lao's fighter planes have long been given a j-20 number. His own side has only the internal number of the factory, but there is no number given by the army. In contrast, Lu Lao prefers to be called J-15.

The j-11-c shows that it is a modification based on the J-11, while the J-15 is a real new aircraft. Of course, they hope to use this number to show that this aircraft is brand new.

As for Mr. Song's j-20, this number is really nondescript. The fighter number of the air force is empty from j-14 to the rear. It comes up to j-20. In this case, ours can also be called j-30. Well, j-30 doesn't sound good. It's simply j-31, which is bigger than you.

Qin Guan was stunned. He didn't worry about naming. These are small things. Of course, since it's good to call jian-15 as a naval carrier aircraft, Qin Guan was wondering why they were in such a hurry to join the service.

"Its technology has been used in the current J-11B. If it does not meet the requirements of the fourth generation aircraft, it seems inappropriate to rush into the service of the new J-11B. The progress in engine development is too slow. Otherwise, we can go into service on a small scale."

The main reason is that the progress of the Tenth Five-Year Plan of turbofans has been delayed. So far, it has not been finalized. Of course, Qin Guan's requirements can not be too high. In ten years, it has been very difficult to spray the second-generation turbofans to the third-generation turbofans in China. The steps are big and it is easy to pull eggs. This kind of aircraft engine can't be anxious. There is no shortcut to take.

If the current turbofan 10 is used as its engine, it is also possible. The problem is that this way does not open enough gap with the J-11B. It is unreasonable to rashly put this aircraft into service for the sake of its little stealth advantage.

Unless you use a new engine, but it's impossible to think about it.

"No, we use a new engine." Lu said, "this engine can meet our requirements in thrust. Although the thrust weight ratio is a little low, it has made the aircraft have all the features of the fourth generation aircraft, and the vectoring nozzle has been assembled in place. Therefore, we hope you can approve it."

Qin Guan was even more confused: "the new engine? Is it a turbofan?"

"No, Mr. Qin, it's r79 engine." Mr. Lu said, "do you remember this engine? It's the engine for the VTOL fighter?"

R79, VTOL? Yes, there was one. At that time, Qin Guan was involved. After the maritime conflict, Qin Guan also realized some advantages of VTOL fighters and decided to do it. At that time, he went to Jacques Design Bureau and pointed out the way of lift fan. At the same time, he also asked President Gu to assist them in research and development, which became an international cooperation project, At that time, Xiong didn't have any extra funds, and Xiong people admired his own technology, so the project team was established. Later, Qin Guan didn't pay attention to it. After all, in his plan, this was only a starting point. When Xiong was divided, he could bring all the people of the whole project to Han for R & D in Han.

Now, it's not that time, so Qin Guan didn't pay much attention, but when he heard what Lu Lao said about r79, he immediately remembered: "you mean, put the r79 engine into our plane?"

The previous projects did not plan to be put into service because the thrust of the engine was not enough. Only 120 kn thrust could not meet the needs of this fourth generation aircraft. Although some basic actions could be done, there was still a great difference in the actual needs. It was necessary to have more than 150 kn thrust to give full play to the performance of this aircraft, Service is valuable.

If there is no gap with the current J-11B, what is the use of service?

R79 engine is such an engine. Its intermediate thrust is close to 11 tons, and the afterburner thrust reaches 15 tons, which means that even without afterburner, this engine is almost the same as the afterburner thrust of turbofan 10. Supersonic cruise and super engine need such strong thrust.

Of course, this kind of engine is still far from the actual needs. The reliability life is put aside. That is to say, the most important thrust weight ratio is only about 7, so the self weight of the engine is very large. Now it is the general pulled out of the shorty. With this kind of engine, Lu decided after studying for a long time. The matching of the air inlet has been done, Waiting for Qin Guan to make a decision.

"This engine was originally hydraulically controlled, but at the suggestion of Lao Gu, it has been changed to full-fledged digital electronic control. We have comprehensive technical data and it is easy to get it. If we get on this engine, we can also update avionics to achieve the integration of flying fire and propulsion. When the engine developed by ourselves is not progressing well, we can use r first It's not the best way for the troops to study the combat mode of this aircraft in advance. We don't need more. Even if Mr. Wang produces ten or twenty aircraft and equips the experimental troops in small quantities, we are satisfied. "
