Super Weapon Exchange System

Old Lu's thoughts were ahead of the other. Just as Qin Guan was thinking about these ideas, another explosive thought of Lu Lao made Qin Guan's eyes widened immediately.

"The last item to be reported is about our stealth version of the J-11 fighter. We hope to approve it to enter the army in small batches."

"Isn't it already in service?" Qin Guan asked, what kind of anti-ship missile he still wanted to use.

"It's not the J-11B, but the real stealth machine. Right now, it doesn't have an official military serial number. We hope to call it J-11C, or J-15 or something like that." .

Their stealth machine was the first to be built. When Mr. Song and the others were still annoyed by the control system of the duck fighter, the fighter in their hands had already taken off, because it was originally improved on the basis of the J-11. Yes, so the progress was rapid, but in the end it was dragged down by the engine problem.

Qin Guan’s advice is to continue to test flight, accumulate experience, and wait for the final engine to mature, and then put into production and service in large quantities, while Mr. Lu and the others began to use the technology of this aircraft to improve the existing fighters and form Partially stealthy J-11B fighter planes, and now, this kind of fighter plane has been in a large number of service, but the real sense of the fourth-generation fighter plane is still in the test flight.

Of course, Mr. Lu was not reconciled anymore. After studying for so long, he couldn't finalize the shape. The day lily was cold. Therefore, now that Mr. Lu took advantage of Qin Guan's arrival, he finally said his aspirations. Our plane should also be in service. Right? When will it be delayed? Woke up early, and then rushed for a late episode.

Lao Song and their fighters were given a J-20 serial number very early. As for their own, they only have the internal serial number of the factory, and there is no serial number given by the army. In contrast, Lao Lu prefers to be called the J-15. .

The F-11C indicates that it is a redesign on the basis of the F-11, while the F-15 is a real new aircraft. Of course, they hope to use this number to show that this aircraft is brand new.

As for Song Lao and their J-20, this number is really nondescript. Air Force fighter numbers, from J-14 to the back, are all empty, and they come up as J-20. In this case, ours can still be called J Thirty, well, F-30 doesn't sound good, it's simply called F31, which is bigger than you.

Qin Guan was taken aback. He did not struggle with the issue of naming. These are trivial matters. Of course, since it is a good name to be called the J-15 as a navy carrier aircraft, Qin Guan is wondering why they are so eager to enter the service. .

"Its technology, we have already used it on the current J-11B. If it does not meet the requirements of the fourth-generation aircraft, it seems that something is wrong with the introduction of the new JJ. The development of the engine is too slow. Otherwise, we can enter the service on a small scale."

The main reason is that the progress of the turbofan 15 has been delayed. Up to now, it has not been finalized. Of course, Qin Guan's requirements cannot be too high. In ten years, it has been very difficult for China to go from the second generation turbojet to the third generation turbofan. , The steps are too big, it is easy to get the eggs, this kind of aero engine, you can't worry, there is no shortcut.

If the current turbofan 10 is used as its engine, it is also possible. The problem is that this method does not open enough gaps with the F-11B. For the slightest stealth advantage, I rushed into it. This kind of aircraft is irrational.

Unless you are using a new engine, it's impossible to think about it.

"No, we are using a new engine." Lu Lao said: "This engine can already meet our requirements in terms of thrust. Although the thrust-to-weight ratio is somewhat low, the aircraft has all four generations of aircraft. Feature, the vector nozzle has also been assembled in place, so we hope you can approve it."

Qin Guan was even more confused: "The new engine? Is it a turbofan 15?"

"No, President Qin, it's the R79 engine." Lu Lao said, "Do you remember this engine? Is it the engine for the vertical take-off and landing fighter?"

R79, vertical take-off and landing? Yes, there was such a model. At that time, Qin Guan intervened. After the maritime conflict, Qin Guan also realized some of the advantages of vertical take-off and landing fighters and decided to do it. At that time, he went to the Jacques Design Bureau. It pointed out the way for the lift fan, and at the same time, asked Mr. Gu to assist in the research and development together, which became an international cooperation project. Anyway, Xiong Guo had no extra funds at the time, and Xiong Guoren's own technology envied him, so the project team It was established. Later, Qin Guan didn’t pay attention. After all, in his plan, this was just a starting point. When the country of Xiong was split, he could bring all the people of the whole project to Han country. Han Guo is engaged in research and development.

Now, it’s not that time yet, so Qin Guan didn’t pay much attention, but now he heard what Lu Lao said about R79, he suddenly remembered: "You mean, this aircraft for us, stuffed into R79. The engine goes?"

The previous project did not intend to serve, because the thrust of the engine was not enough, with only 120 kN thrust, which could not meet the needs of this fourth-generation aircraft. Although it can also do some basic actions, it still meets the actual needs. There is a big difference, and it must have a thrust of more than 150 kilonewtons before the performance of this kind of aircraft can be brought into play, and it has value in service.

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

The R79 engine is such an engine. Its intermediate thrust is close to eleven tons, and the afterburner thrust reaches 15 tons, which means that even if the engine does not use afterburner, it will The turbofan ten's afterburner thrust is almost the same. Supersonic cruise and super maneuverability require such powerful thrust.

Of course, this kind of engine is still far from the actual needs. Put aside the reliability and life, the most important thrust-to-weight ratio is only about 7, so the weight of the engine is very large. General, the use of this kind of engine was determined by Mr. Lu after a long time of research. The matching of the air intake was completed, and he waited for Qin Guan's decision.

"This engine was originally hydraulically controlled, but it has been changed to full-power digital electronic control under the advice of Gu and them. We have comprehensive technical information and it is easy to take it. If you use this engine, then We can also update the avionics to reach the level of integration of flying fire and propulsion. In the case of the unfavorable progress of the engine developed by our own, we first use R79 as an emergency and give it to the army. It also allows the army to study the combat method of this aircraft in advance Isn’t this the best? Don’t need too much. Even if we produce ten or twenty aircraft and equip the experimental units in small batches, we are still satisfied.”
