Chapter 199 (1/2)

At the same time, Wang Bin can also clearly see in his telescope that the speed of the UAV at this time has obviously increased a lot, and soon formed a special cloud in the middle of the aircraft when the aircraft broke through the sound barrier.

However, as the speed of the aircraft continued to increase, these special clouds began to disappear.

Just then! Jia Jie said, ”the UAV has broken through the sound barrier, with a speed of Mach 1.1.”

”Continue to speed up until you reach the maximum speed!” Wang Bin said busily.

”Yes!” then, Jia Jie adjusted the public output column of the UAV to the maximum.

As the engine horsepower of the UAV reaches the maximum, soon, the speed of the UAV also reaches the design maximum speed.

However, the UAV is still accelerating at this time. Although it has reached the design maximum speed, it does not mean that the maximum speed of the aircraft can only reach this speed. After all, the design maximum speed is under the condition of full oil and full load, that is, the ultimate takeoff weight of the aircraft, 16.3 tons.

Now the UAV is neither full of oil nor loaded with anything, and even all kinds of air to ground search radars are not installed. Now the whole aircraft adds up to only 67 tons, so naturally its speed will be higher.

Soon, the speed of the aircraft broke through Mach 1.6 and reached Mach 1.7, but the speed of the aircraft is still increasing rapidly.

”Mr. Wang! The speed of the UAV has reached Mach 1.7 and is still accelerating! Do you want to stop accelerating?” when the plane reached Mach 1.7, Jia Jie asked Wang Bin with some worry.

After all, the maximum speed of this aircraft at the time of design is only Mach 1.6! Now the speed of the plane has exceeded Mach 1.7, so he is worried that the collective structure of the plane can't stand it.

However, Wang Bin's answer forced him to continue to accelerate the plane.

”No, keep accelerating. Since it's a test flight, we have to measure the ultimate speed of the UAV.” although Wang Bin knows Jia Jie's concerns, he still orders Jia Jie to continue accelerating.

Although Wang Bin himself was worried that the collective structure of the aircraft would not stand at such a speed, it was obvious that Wang Bin's worry was superfluous. Shortly after he gave the order, the speed of the UAV broke through the limit again and reached Mach 1.9.

At this time, the speed of the UAV still did not reach the limit output by the aircraft engine and continued to accelerate until the speed of the UAV passing through No. 001 reached Mach 2.06. Finally, the speed of the UAV stopped at the level of Mach 2.12.
