This kind of high-thrust turbofan engine is a huge difficulty for aero engines. Only the most technologically advanced countries can build it. Now, apart from the Eagle Country, there is only Han.

Moreover, this engine of Han Guo is obviously very mature. This medium-sized fighter can be propelled by just such an engine.

"Yes, its cost is quite high, which is also one of the reasons for the high price of this kind of aircraft." Qin Guan said: "Moreover, in the research and development expenses, the research and development expenses of this engine are not included. Twice is possible."

The research and development cost of this aircraft of Han State is only 3 billion, which is quite cheap, which makes the whole world unable to believe that it is only a fraction of Eagle State. Now Qin Guan has said that an important reason is that it does not include the engine. Research and development expenses.

In other words, the profit of the engine on this aircraft is exclusively owned by Han. The engine has a thrust-to-weight ratio of 10, and the maximum thrust exceeds 150 kN, which is equivalent to that of an ordinary aircraft. Two sets are of course extremely valuable.

This also shows that Han's industrial strength has reached the peak of this world.

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

The original shape of the airplane is bloated enough, plus only one engine, so its maximum speed cannot reach Mach 2. Facing Rafael’s sigh, Qin Guan just smiled faintly: “You want It's fast, easy to say, do you want a MiG-25? I'll get you some back."

The relationship between the Davidians and the bear country is not good. After all, the bear country has always supported the countries surrounding the country. Therefore, although the bear country collapsed, the Davidians can only watch the benefits and cannot divide it. A piece of pie, and Han is different. Now Qin Guan really doesn't speak big words. If they need it, Qin Guan can really get it.

MiG 25, Mach 3 fighter, would you like it?

Of course not. What is the use of this kind of airplane?

Just as everyone sighed, there was another roar in the distance. The aircraft with a similar shape actually came back. When they looked at the markings on the nose, they knew that this one was different from the one just now, and, When we got closer, we could find that the speed of the plane suddenly slowed down, and then an opening appeared on the back of the plane.

Lift engine! This plane has completed the test flight and plans to land here!

The Davidians watched enviously. After the plane approached, the speed became slower and slower. According to the normal flight, the plane has fallen down at this speed because the plane's wing lift is not enough, but For this aircraft, it doesn’t matter, because the tail nozzle of the engine has begun to deflect downwards, and the lift fan has also started to run. The lift lost by the wings is all provided by the power system, so that it continues to maintain a stable attitude. , Slowly approaching the apron.

When it reached the sky above the tarmac, the speed of the aircraft gradually decreased to zero, and then the fighter began to adjust its attitude again, and turned a little around the axis, and then the aircraft began to slowly land. The whole action was completed in one go, showing the pilot's extremely high flying standard.

The most challenging aspect of a vertical take-off and landing fighter is the take-off and landing stage. This requires careful manipulation by their pilots, just like a Sea Harrier fighter. When landing, the pilot's heartbeat can exceed one hundred, and every time they play, they are heartbeats.

"The pilot's skills are really good. It seems that it takes hundreds of takeoffs and landings to be so proficient." Rafael sighed. Test pilots have come to fly now, and it must be the result of quite superb technology and long-term operation.

At this moment, Lao Sun said: "Pilot, almost no operation."

"How is this 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 take-off and landing procedures that can meet landings in various situations. Of course, as a backup, the pilots should have the same Operation ability to prevent accidents."

"Computer control?" Rafael sighed: "In this case, how powerful is the computer performance?"

"Probably equivalent to the performance of our Hanxin No. 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 strong. However, military chips are definitely not comparable to civilian chips. Military applications must take into account the need for electromagnetic pulse protection. With various reinforcements, performance can reach half of civilian use.

The problem is that Han's civilian chips are also very abnormal. It can reach the level of civilian 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 be completed. This kind of automatic take-off and landing program control.

Relying on advanced electronic systems, Han has successfully promoted the progress of the entire industry, especially in the defense industry, which is even more so perverted. 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 enough thrust, so this sound is louder than the roar of a high-speed turbine, like the sharpest The sound from the whistle has expanded a hundred times, and everyone feels that their eardrums have been broken.

Then, the sound disappeared.

The landing process is over. The test pilot's canopy turned forward. The test pilot came out from inside, stepped down the gangway, and said to Lao Sun: "Today's test flight has been completed."

When this man spoke, his tone was very strange, and when he saw his figure a little tall, Rafael and others were very strange. They didn't see this man's golden flat head until he took off his helmet. Suddenly I was surprised: "This person is?"

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

Bear countryman!

It's no wonder that the Han people are progressing so fast. It turns out that they have absorbed a large number of Xiong people. This aircraft has a large number of Jacques blood. It seems that this test pilot is also from the Jacques Design Bureau?

They guessed it was right. This fighter was progressing so quickly, of course, it was inseparable from the Yakleev Design Bureau. Qin Guan moved almost the entire design bureau, and naturally there were pilots from their design bureau.

For those people, it's no better to live here. They are all used to it, and many people can even communicate in simple Chinese, such as this pilot.

Rafael and Graça both had surprised eyes. At this moment, the roar in the distance surprised them again.

A large aircraft with variable swept wings is preparing for landing. The huge rectangular air inlets on both sides of the aircraft are so conspicuous. This aircraft is the most proud of Xiong Guo Tu-22M Bomber right?
