Chapter 210 (1/2)

Wang Bin, general Qiu, chief engineer Lin and others soon came to the tower of the base. After all, it was a manned test flight. With the naked eye alone, the range they could see was very limited. Even with a telescope, the range they could see was very limited.

However, according to the subjects of the test flight, the test flight not only needs to test various ordinary actions, but also needs to test the maximum speed and maximum height.

After all, according to the original data of Qiye, that is, the data before replacing the engine.

Its maximum speed can also reach Mach 2.0, and its maximum height can reach an altitude of 20000 meters.

So what they want to test is whether the seventh master can meet higher requirements in terms of maximum speed and maximum height after installing a new engine.

As for whether the seventh master can support the fuselage at such a high speed and height, whether general Qiu or chief engineer Lin of the base are not worried about this. After all, they know very well about the seventh master.

What's more, the seventh master, who is preparing for a test flight, is not an ordinary seventh master. Many of its key parts have been specially treated, so the strength of this seventh master's body is definitely much stronger than that of an ordinary seventh master.

”Take off!” as the command came from the tower, Zhao Feng immediately gently pushed the operating lever. Under the action of the engine, the aircraft began to slide slowly towards the front, and the speed began to accelerate gradually. With the acceleration of the speed and meeting the take-off requirements of the seventh master, Zhao Feng immediately pulled up the operating lever, and the seventh master left the ground at once, And almost at an angle of 45 degrees, he rushed into the air. Even at this upward takeoff angle, the seventh master not only didn't slow down, but also accelerated.

Obviously, after the new engine is installed, the power of the seventh master is stronger. If the old engine is replaced, when taking off, don't say the angle of 45 degrees. Even if it is 30 degrees, the seventh master can't basically do it, let alone increase the speed of the seventh master during the flight at this angle.

Wang Bin and others on the ground are also very excited. After all, they took off successfully and took off at a large angle, which means that their engine is definitely a qualified engine.

Professor poke and others also looked a little excited. After all, Professor poke made the greatest efforts in the R & D process of this engine.

Although the drawings of this engine are provided by Wang Bin, Professor Zhang is responsible for the modification, manufacturing and commissioning of this engine. Only Professor Zhang knows how much effort and hardships he has made during this period.

At this time, all the people in the air force base, including general Qiu, the pilots without tasks, and the ground crew, all looked at the seventh master in the air.

Compared with Wang Bin, they are the people who know the seventh master best. Now the seventh master takes off at such a large angle, which makes them look forward to the engine on the seventh master even more.

When the seven masters flew to a certain height, Wang Bin picked up a telescope to watch the seven masters in the air doing all kinds of actions.

I saw the seven masters in the air sometimes turn with a large radius, sometimes turn with a small radius, sometimes dive, and sometimes snake maneuver in the air. It can be said that these movements made by the seven masters in the sky are no worse than those made by the national performance team, but because there is only one plane, the effect is not as spectacular as those performance teams.

Soon, all the low altitude flight test action subjects were completed one by one. At this time, the aircraft reached the subject of low altitude high-speed flight test stage.

”Report to the tower that the aircraft is in good condition and the engine is normal. Apply for low altitude and high-speed flight test.” Zhao Feng's voice came from the horn on the tower command console.

”You can fly at low altitude and high speed!” after hearing Zhao Feng's words, the commander of the tower looked at general Qiu and saw that he ordered you to fly at low altitude and high speed, so he ordered.
