The normal first flight is not to get the landing gear to avoid problems. The aircraft is more like a normal production line. The pilot has just pulled it up, the pilot has recovered the landing gear, and then continues to climb to the sky. Although it is a single fighter, there is no mounting and the climb of the fighter is awesome.

"Mr. Qin, I just saw something special in the nose?" said an air force general of Shengjie country.

"That is our passive detection system, which can also provide all kinds of data for launching missiles without turning on the radar," Qin Guan said.

Since it is a stealth aircraft, there must be something unique to the stealth aircraft. Now, the main means of detecting the target is radar, but the airborne radar will be detected by the other party when it is turned on. Therefore, if there is a passive detection device, it is obviously a better choice.

In fact, there is this kind of photoelectric aiming system on the male cat fighter. The Han country obtained this kind of device on their third generation aircraft from the Xiong country. Combined, it soon saved its own new generation of photoelectric aiming system. This is a comprehensive passive device, including infrared and optical imaging devices, with high sensitivity, which can enable pilots to detect and lock targets more effectively.

In the future air combat, fighters do not need to turn on the radar. With the support of the data link of the early warning aircraft, they fly to the target, observe the target with their own passive system, and then turn on the radar briefly, launch missiles, shoot down the target, and then come back. All these are carried out quietly.

This small component also shows the advanced technology of the Han country. Everyone looks at it with an appreciative expression. The fighters of the Han country have roared away from their vision and flew into the sky.

They looked at the tail of the body, the front and top of the hot tail nozzle, and the two vertical tails looked so eye-catching, which was also a sign of the stealth aircraft!

"I'm afraid its vertical tail must also be controlled by telex?" at this time, general Jamal reacted and asked Qin Guan.

In the past, lightning fighters only used telex in the pitch direction and mechanical hydraulic control in other directions, which can save the most cost. It can also give the fighter's navigation equipment the ability to automatically attack the target and then pull it up.

Now, the shape of the vertical tail has changed.

It is normal for the vertical vertical tail to deflect the rudder surface at the tail to push the air flow and drive the fighter to turn. However, now, after the vertical tail tilts, the rudder surface deflects and the blowing air flow is inclined, and the deflection angles of the rudder surfaces on both sides cannot be the same. These cannot be controlled by hydraulic pressure. You must send a telex.

Moreover, if the fighter wants to turn, it depends not only on the rudder at the tail, but also on the rudder surface at the trailing edge of the wing to drive the wing to deflect, so it can provide sufficient centripetal force to complete the steering. Therefore, when the pilot turns, he uses the pull rod to pedal the rudder and operate together.

Now, since telex operation is also used in the vertical tail, the control of the wing must also be telex control, that is, it is upgraded from single axis to three-axis telex control, which will increase the cost.

"Yes, general, you are really an expert. This kind of fighter can only be controlled by digital telex with three axes and four redundancy," Qin Guan said.

Therefore, in terms of control, it will certainly increase the cost. General Jamal secretly thought that the performance of this aircraft is advanced, but the cost will certainly increase. So, is it cost-effective?

When the fighter plane made its first flight, it didn't fly smoothly. After it got on, there was a roll. There was a cheering from the test pilot on the radio: "this plane is great. It's better than the original mobility!"

The double vertical tail reduces the overall height of the fighter and makes the steering of the fighter more agile. In addition, the use of digital telex control makes the response of the aircraft more sensitive. It can be said that this kind of aircraft is absolutely a king in light aircraft!

The voice of the test pilot echoed in his ears. Then, he made several maneuvers in the sky. It can be seen that people on the ground are itching. Although this kind of aircraft has just begun trial production, it is already a mature model. After all, it still has the foundation of the previous lightning fighter.

The fighter plane flew in the air for half an hour before it finally landed. When the plane had just stopped, the people had already rushed over. Qin Guan had said that they would not be allowed to visit until the fighter plane came down.

As soon as the ground crew put up the ladder, lieutenant general murendez was the first to climb up. He was also a pilot and flew over F16. He shouldn't be so anxious. However, when he saw the fighter in front of him, he couldn't control his surprise and joy. He climbed up and looked at the cockpit inside, which was even more surprised.

There are no mechanical instruments in the cockpit. In the whole cockpit, there are only three flat displays. All data are displayed in these three displays. Together with the head up display in front, it forms a layout of one flat and three bottom. This is the most modern glass cockpit, which is much better than their F16!

Lieutenant general mullundez stepped into the cockpit. When he held the operating lever, he found that this fighter was more suitable for his body. The body size of the people in lazhou oil country was similar to that of the Han country. F16 was prepared for tall Western pilots. When they flew, they always felt that the cockpit was too big. Now, the cockpit was just right. The positions of various operating levers and so on, Are quite good.

"Yes, it's really good. How much is this plane?" lieutenant general mulendez asked. When he was in the holy country, he had seen the lightning fighter. The plane in front of him was obviously better than the lightning fighter.

He fell in love at a glance. They don't need money. As long as they like it, they can buy it back!

"Well, we're still developing it for the time being." Qin Guan said, "you should know that the test flight may last for a long time. We can't sell the problematic fighters directly. When the test flight is over and officially sold abroad, there may be inflation during this period, so we really can't say much money now."

Sell it now? Of course not. It's necessary to lift the other party's appetite. Moreover, Qin Guan is talking about the actual situation. After all, in recent years, inflation has been very serious in the world. Now place orders and wait until delivery, the original price may not be enough, even the cost. It's a loss to do business.

Lieutenant general mulendez could only shake his head helplessly and was very moved to see this aircraft, but now, they can only buy the most common lightning first and wait until the R & D of this fighter is completed.
