Chapter 2898

This kind of high thrust turbofan engine is a huge difficulty in aeroengines. Only the most technologically advanced countries can build it. Now, in addition to the eagle country, there is only the Han country.

Moreover, the engine of the Han country is obviously very mature. This medium-sized fighter can be driven by such an engine alone.

"Yes, its cost is quite high, which is one of the reasons for the high price of this aircraft." Qin Guan said: "moreover, the R & D cost of this engine is not included in the R & D cost. Otherwise, it is possible to double the cost."

The R & D cost of this aircraft in the Han country is only $3 billion, which is quite cheap. The world can't believe it. It's just a fraction of the eagle country. Now Qin Guan has said that an important reason is that it doesn't include the R & D cost of the engine.

In other words, the profits of the engines on this aircraft are exclusively owned by the Han state. The thrust to weight ratio is 10, and the maximum thrust is more than 150 kn. One is equivalent to two ordinary aircraft. Of course, it is extremely valuable.

This also reflects the industrial strength of the Han country, which has reached the peak of the world.

"However, after all, the power of an engine is not enough, and the maximum speed of the aircraft is not high," lafar said.

The plane was bulky enough, and there was only one engine, so its maximum speed could not reach Mach 2. Facing lafar's exclamation, Qin Guan just smiled faintly: "you want to be fast. It's good to say, do you want MIG 25? I'll get you some back."

The relationship between the Davidians and the state of Xiong is not good. After all, the state of Xiong has always supported the countries around the state of David. Therefore, although the state of Xiong collapsed, the Davidians can only watch the benefits and can't take a share. The state of Han is different. Now Qin Guan really doesn't talk big. If they need it, Qin Guan can really get it over.

MIG 25, Mach 3, you want it?

Of course not. What's the use of this kind of plane?

When everyone sighed, there was another roar in the distance. The aircraft with similar shape actually came back. When they saw the sign on the nose, they knew that this one was different from the one just now. Moreover, when they approached, they could find that the speed of the aircraft suddenly slowed down. Then, an opening appeared on the back of the aircraft.

Lift engine! The plane has completed its test flight and plans to land here!

The Davidians looked at it with envy. After the aircraft approached, the speed became slower and slower. According to the normal flight, the aircraft had fallen down at this speed, because the wing lift of the aircraft was not enough, but it didn't matter to the aircraft, because the tail nozzle of the engine began to deflect downward and the lift fan began to operate, The lift lost by the wing is all provided by the power system. In this way, it continues to maintain a stable attitude and slowly approaches the apron.

When the aircraft reached over the apron, the speed of the aircraft gradually decreased to zero. Then, the fighter began to adjust its attitude and rotate slightly around the axis. Then, the aircraft began to land slowly. The whole action was done at one go, showing the pilot's high flying level.

The most challenging stage of VTOL fighter is the take-off and landing stage. This requires careful control by their pilots, just like a harrier fighter. When landing, the pilot's heartbeat can exceed 100, and it's heartbeat every time.

"The pilot's skill is very good. It seems that he can be so skilled only after hundreds of take-off and landing." lafar sighed. Now it's all test pilots who come to fly. It must be the result of quite superb technology and long-time operation.

At this time, Lao Sun said, "pilot, almost no operation."

"How could this be possible?" Rafael couldn't believe his ears when he heard Lao sun's words.

"The whole process is controlled by the computer itself." Lao Sun said, "we have a complete set of perfect take-off and landing processes, which can meet the landing under various circumstances. Of course, as a backup, the pilot had better have the same operation ability to prevent accidents."

"Computer control?" lafar sighed. "How powerful should the computer performance be?"

"It's probably equivalent to the performance of our Hanxin 3 chip," Lao Sun said.

If you want to land automatically, you need to write a lot of programs. Therefore, the performance of the flight control computer must be powerful. However, military chips can't be compared with civilian chips. The military should consider the need of anti electromagnetic pulse and carry out various reinforcement. In terms of performance, it's good to reach half of that of civilian chips.

The problem is that the civilian chips in the Han Dynasty are also very abnormal. They can reach the level of Hanxin 3, which is almost equivalent to the level of mainstream civilian chips in other countries in the world. Only chips with this performance can complete this automatic take-off and landing program control.

Relying on advanced electronic systems, Han successfully promoted the progress of the whole industry, especially in the national defense industry. Rafael's heart was extremely shocked.

At this time, the roar of the engine is louder, especially the lift fan, which relies on high speed to provide sufficient thrust. Therefore, the sound is louder than the roar of high-speed turbine, just like the sound from the sharpest whistle has expanded a hundred times, and everyone feels that their eardrums have been broken.

Then the sound disappeared.

The landing process was over. The test pilot's cockpit cover turned forward. The test pilot came out, stepped down the gangway and said to sun, "today's test flight subject has been completed."

When the man spoke, his tone was very strange. Moreover, looking at his tall figure, lafar and others were very strange. Until the man took off his helmet, they saw the man's golden flat head and were surprised: "who is this man?"

"He is our foreign aid pilot." Lao Sun said with a smile.

Xiong Guoren!

No wonder the Han people are making such a rapid progress. It turns out that they have absorbed a large number of Xiong people. This plane has a large number of Jacques descent. It seems that this test pilot is also from the Jacques design bureau?

They guessed right. The fighter plane made such rapid progress. Of course, it was inseparable from the yaklev Design Bureau. Qin Guan almost moved the whole design bureau. Naturally, there were also pilots from their design bureau.

For those people, it's great to live here. They are used to it. Even many people can communicate in simple Chinese, such as the pilot.

Lafar and glasa both looked surprised. At this time, they were surprised by the roar in the distance.

A large aircraft with variable swept wings is preparing to land. The huge rectangular air inlets on both sides of the aircraft are so conspicuous. Is this aircraft the most proud tu-22m bomber in bear country?
