Chapter 668 (2/2)

Hearing the German old man speak, the two dare not hesitate. Andrepov immediately replied, ”commander in chief, at present, everything is normal and the flight attitude is good. The electronic equipment works normally and the fuel consumption is normal. ”

Hearing this, there was another cheering inside the tower. Fortunately, everyone knew the control and soon entered the working state again.

Frank Horton: ”good, now it can rise to 15000 meters; Keep the situation informed. ”

Andrepov pulled up the plane and climbed to an altitude of 15000 meters. Most civil aircraft cannot reach this altitude at all, so the requirements for engines are higher.

The higher the height, the thinner the air, and the higher the working efficiency of the engine. At present, it seems that the heiyun turbofan 2 engine is fully qualified and even exceeds the design performance in some aspects.

Relying on the powerful climbing performance of the engine, the plane soon reached an altitude of 15000 meters. Zhao Jun began to check various data, which is the highest altitude of today's test flight; The boss is right below. Success means appreciation and salary increase. Failure is hard to say.

Andrepov tested the thrust of the engine to reach this altitude and saw the engine power value. The experienced pilot felt that even if the engine rose to 25000 meters, there was no problem. It seems that the aircraft still has a lot of room to improve.

This aircraft is based on German design, but everyone knows it. The real core technology comes from baozixuan, a young and disgraceful boss.

Suddenly, the plane shook, which was not just felt by the pilot; Even the staff on the ground detected it. Seeing the nervous state of the staff, baozixuan didn't speak, just watching the data on the big screen.

At this time, we should choose to believe, not give them pressure.

The ground computer quickly calculates the cause of jitter through the data sent by the sensor. There is a problem with the counterweight ratio between the front and front passengers. Although the values are not different, there will still be some hidden dangers.

It's easy to know the result. Frank Horton hurried to return the plane. The purpose of the first test flight has been achieved. The aircraft does have some small problems to be solved, and safety is the first.

Andre boff didn't dare to lift up, so he quickly adjusted his flight attitude and flew towards Tianshui. At this time, the ground staff began to get nervous again. The most dangerous time in the flight process is take-off and landing, and the risk factor of landing is higher. However, we can't help. They can only do a good job in the detection data. The rest depends on the specific operation of the pilot.

The wing area of HH-01 is very large, which makes the landing very smooth. However, the flat fuselage also has a trouble, that is, it has little air resistance. It can't provide higher resistance when landing. Fortunately, this problem has been considered in the design. There is not only a parachute, but also the engine will push back, otherwise a bad plane can't stop.

They landed according to the operation process, and the plane stopped quickly. The ground crew began to pick up the pilot, and the engineer began to test all parts of the aircraft.

When andrepov and Zhao Jun got off the plane, they were greeted with warm applause and flowers. This is the rule, which is common in air forces all over the world.

Bao Zixuan smiled and said, ”how do you feel, two warriors.”

Andre boff smiled and said, ”the performance of the aircraft is very strong, even beyond imagination. This is definitely the best plane in the world, and there is no one. ”

Zhao Jun also smiled and said, ”the performance of airborne electronic equipment is very powerful, so I have nothing to do.”

Although this is a joke, it also shows that HH-01 aircraft meets the design requirements in disguise. The next step is to continuously improve and perfect, so as to meet the service requirements.

Steamed stuffed bun Xuan didn't say much. Now he needs to establish authority for Frank Horton; If you want to announce anything, you can wait until the celebration banquet.

Looking at the data reports, Frank Horton was very excited. He really succeeded. He finished what his uncle and father didn't do. I believe the two spirits in heaven can rest in peace.
