Wang Bin, General Qiu, Chief Engineer Lin and others soon arrived at the base's tower. After all, this was a piloted test flight. With the naked eye, the range of visibility was very limited, even using a telescope. The scope of its seeing is also very limited.

However, according to the subjects of the flight test, this test flight not only requires a test flight of ordinary various actions, but also a test of maximum speed and maximum altitude.

After all, according to Qiye's original data, that is, the data before the engine was replaced.

Its maximum speed can also reach about 2.0 Mach, and the maximum altitude can reach an altitude of 20,000 meters.

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

As for whether Qi Ye's fuselage can support life at such a speed and such a height, whether it is General Qiu of the base or General Lin, etc., are not worried about this. After all, they are very concerned about Qi Ye. Of understanding.

What's more, this Qiye, which is preparing for a test flight, is not an ordinary Qiye. Many of its key parts have been specially treated. Therefore, the strength of the body and fuselage of this Qiye is definitely better than that of ordinary Qiye. Master is a lot stronger.

"Take off!" Following the command from the tower, Zhao Feng immediately pushed the control lever gently. Under the action of the engine, the aircraft began to glide forward slowly, and the speed began to increase gradually, as the speed increased. , And when Qi Ye's take-off requirement was reached, Zhao Feng immediately pulled up the control stick, and Qi Ye immediately left the ground and rushed into the air at an angle of almost 45 degrees, even at such an upward take-off angle. At this time, Qi Ye not only did not slow down, but was still accelerating.

Obviously, after the new engine is installed, Qi Ye's power is stronger at this time. If it is replaced with an old engine, not to mention the 45-degree angle when taking off, even if it is a 30-degree angle. The master basically couldn't do it, let alone, the speed of the seventh master was still increasing during the flight at this angle.

Wang Bin and others on the ground were also very excited. After all, the takeoff was successful and the takeoff was still from a large angle. This means that their engine is definitely a qualified engine.

Professor Poke and the others also looked a little excited. After all, Professor Poke made the greatest effort during the development of this engine.

Although the drawings of this engine were provided by Wang Bin, Professor Piao was solely responsible for the modification, manufacture, and test run of this engine. Only Professor Piao knew how much effort and hardship he had put in during the period.

At this time, everyone in the entire air base, including General Qiu, pilots without missions, and ground crews, all looked at the Qi Ye in the air.

Compared to Wang Bin and the others, they are the people who know this Qiye best, and now the Qiye takes off from such a big angle, which makes them look forward to the engine on the Qiye even more. .

When the Qi Ye flew to a certain height, Wang Bin picked up the telescope and watched the Qi Ye doing various actions in the sky.

I saw the Seven Masters in the air turning sometimes with a large radius, sometimes changing to a small radius, sometimes doing a dive, and sometimes doing a serpentine maneuver in the air. It can be said that the seven masters in the sky made these movements. It's no worse than the action done by the national performance team, but because there is only one aircraft, the effect is not as spectacular as those of the performance team.

Soon, all the low-altitude flight test subjects were completed one by one. At this time, the aircraft entered the low-altitude and high-speed flight test phase of subjects.

"Report to the tower, the aircraft is in good condition, and everything is in order for the engine to apply for a low-altitude and high-speed flight test." Zhao Feng's voice came from the horn on the tower's command podium.

"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 low altitude and high speed flight, so he ordered.

Following the command of the tower, I saw a stronger engine sound coming from the direction of Qiye in the air, and Qiye also changed his flying attitude, into a level flight attitude of flying eastward, and the plane's Speed ​​is also increasing rapidly.

Not long after, Zhao Feng's voice came from the tower's horn again: “Report to the tower that the aircraft has broken the sound barrier. The current speed of the aircraft is Mach 1.2 and the aircraft is still accelerating.”

"Mach 1.23!"

"Mach 1.28!"

"Mach 1.45!"

"The aircraft has reached Mach 1.7, in good condition, and the engine is very powerful." Soon, the aircraft reached a speed of Mach 1.7! You know this is the speed at low altitude!

However, after the Qiye reached this speed, the tower ordered Zhao Feng to increase the flight altitude and conduct a test flight at the maximum altitude and maximum speed. Now the aircraft's speed at low altitude has reached Mach 1.7, which is very high at low altitude. Dangerous, if you are not careful, there is a high possibility of plane crashes and deaths. For the sake of safety, the low-altitude test ends here.

Compared with the test data and aircraft, Zhao Feng's life is more important as an excellent Chinese pilot. As for the maximum speed test at low altitude, Wang Bin and the others can put it on other aircraft, such as drones for testing.

Within a few minutes, Zhao Feng reported to the tower. At this time, he had reached an altitude of 15,000 meters, and the altitude was still rising. At the same time, the speed of the plane was slightly higher than before, reaching Mach 1.8. .

"Continue to raise your altitude until the limit that the aircraft can raise. In terms of flight speed, continue to increase speed." The tower continued to command immediately.

"Understand!" Zhao Feng's answer came from the horn~www.mtlnovel.com~ At the same time, the radar on the tower side also showed the height and speed of the Qiye that Zhao Feng was driving at this time.

16,000 meters, 17,000 meters... 20,000 meters, and soon the altitude of the plane has already exceeded the highest altitude Qiye could reach, and Qiye's ascent speed is still very high at this time. Fast, did not slow down because the altitude has exceeded the original limit.

At the same time, the speed of the aircraft, as the altitude increases, the air becomes thinner and the drag becomes smaller, and becomes faster, and soon exceeds the limit of Mach two, which is the original limit of the original Qi Ye, and is still increasing rapidly.

After all, the original engine of Qi Ye has a maximum thrust of less than five tons. Even if the afterburner is turned on, its maximum thrust is less than six tons.

And the engine installed by the Qi Ye! Its maximum unpowered thrust has reached fifteen tons! But Qiye's original engine has three times the thrust!

This is still the case without afterburner. If the afterburner is applied, it will definitely exceed 16 tons, so this Qiye can continue to increase the height and speed after breaking the original speed and height limit.
