Chapter 199 (2/2)
”Mr. Wang! The speed of Tiangong 001 is Mach 2.12, the aircraft speed is good, the internal vibration is good, and the internal structure is good! Everything is normal.” when the speed of the aircraft reached the limit, Jia Jie immediately reported the situation of the aircraft.
”Start the test of turning and other actions at the limit speed, and record the data changes inside the aircraft!” after listening to Jia Jie's report, Wang Bin nodded.
However, after listening to Wang Bin's words, Jia Jie did not immediately execute Wang Bin's orders, but asked Wang Bin: ”Mr. Wang, do you really want to operate like this? After all, this is a turn at the extreme speed of Mach 2.1. When turning at this speed, the aircraft has to bear extraordinary load and the internal structure has to bear strong pressure. Once the turning process exceeds the limit that the internal structure can bear, the aircraft is likely to disintegrate on the spot Yes. ”
”Yes! Mr. Wang, it seems that this UAV of Tiangong technology is only the first flight test this time! I don't think it's necessary. After all, there are opportunities for such action test in the future!” chief engineer Lin also said.
To tell the truth, for chief engineer Lin, Wang Bin's first flight test of Tiangong technology was too rough. How could an aircraft make such rough actions when it was the first flight test? Let alone the turning beyond the limit speed he just issued, even if it was the limit speed test they had conducted before, if it was in accordance with the normal flight test conditions, it would be necessary It will not be carried out until the aircraft has carried out many test flights, not to mention turning at the limit speed. After all, the loss of the aircraft is very huge. Even if you are not careful, it may lead to the disintegration of the aircraft and the complete failure of the test flight.
However, Wang Bin doesn't care about their worries. After all, for Tiangong technology, although the cost of this UAV is nearly ten million, because the cost of the engine alone is as high as five or six million. If scientific research funds are added, the price will be higher, but it's nothing for Tiangong technology. For Wang Bin, Now the most important thing is to collect all the data of the aircraft.
So he ordered Jia Jie: ”according to what I did, even in the process of test flight, the plane really broke down or disintegrated. It's a big deal to build another one. We can afford to lose. What's more, I have confidence in our Tiangong 001 UAV.”
After listening to Wang Bin's words, Jia Jie didn't say anything. After all, who called Wang Bin the boss of Tiangong technology! What's more, it's also true that Wang Bin said. For his current Tiangong technology, even if there is a problem with this aircraft, it's a big deal to build another one. The most important thing is that they have obtained the data they want to obtain.
After listening to Wang Bin's words, chief engineer Lin shook his head and said nothing more. After all, this is just a UAV, and no one is flying the plane. If someone is flying the plane, chief engineer Lin will not let it carry out such a rough test flight, and the UAV is different. The big deal is to lose a UAV. As long as the data is obtained, They can build another UAV at any time with Tiangong technology.
Then, Jia Jie operated the UAV and carried out a series of turning actions. These actions include large radius turning, small radius turning and turning in all directions. Until nearly half an hour of test flight, Jia Jie reported to Wang Binhui: ”Mr. Wang, the aircraft is about to run out of fuel. Would you like to return?”
”Yes, but when we return, we have to carry out the final subject test, that is, the test of this UAV under five fuel conditions.
Jia Jie now turns off the aircraft's fuel output system and turns on the electric drive to return.
”Yes! Mr. Wang!” then he turned off the personnel output of the aircraft and turned on the electric drive system of the aircraft.
With Jia Jie's operation, the roar of the originally roaring aircraft suddenly disappeared, which made everyone present except Wang Bin, Jia Jie and chief engineer Lin very confused. They thought whether the UAV test flight failed this time.
Of course, it's not that after the UAV is changed to electric drive, the UAV Engine has no sound. In fact, after the UAV is changed to electric drive, the UAV Engine continues to make a huge roar, but the sound is much lower than that when it is driven by fuel. However, even so, in fact, it can be heard on Wang Bin's side The roar of.
