Chapter 374 Phoenix Second Test Flight
And Wang Bin naturally knows clearly that in today’s flight test subjects, there is indeed no high-altitude high-speed project, that is, there is no flight test project with an altitude of more than 10,000 meters and a speed exceeding Mach 1, so Wang Bin nodded, yes. Master Qiu said: “Master Qiu! Tell the crew to reduce their speed and altitude!”
And while Wang Bin was talking with Qiu Shi, the speed of the aircraft had reached Mach 0.98, and the altitude had reached a height of 10,000 meters, which means that the speed of the aircraft had reached Mach. At the limit of subsonic speed, with a little more force, the aircraft can break through the silver medal and reach a speed of Mach one.
However, at this time, the crew of this aircraft also obviously knew that there was no supersonic flight test program or high-altitude flight test program in today’s flight test subjects. Therefore, after reaching this speed, the Phoenix-1 No. Instead of continuing to accelerate, the aircraft’s speed and altitude were maintained at this stage. It was only when Qiu Shi ordered a reduction in altitude and speed that the crew of the aircraft lowered the aircraft’s altitude and speed.
But even so, the aircraft’s altitude was maintained at about nine kilometers, and the flight speed was maintained at about Mach 0.9.
Although the body is the first flight test of this aircraft, the various data during the flight test are very good. The data is also exceptionally stable, which makes Qiu Shi and others smiles. It is obvious that they are very satisfied with the flight performance of the aircraft at subsonic speeds.
Afterwards, everyone noticed that the speed of the aircraft began to drop again, but the altitude did not change. When the speed of the aircraft dropped to Mach 0.7, the Phoenix-1 No. 1 aircraft began to perform various actions. The flight test subjects include large-radius turns, small semi-warp turns, rapid ascending, rapid descent, minimum high-altitude flight speed, and so on.
With the progress of each item of flight subjects, until all the flight items are completed, this Phoenix No. 1 aircraft finally started to return, but both Wang Bin and Qiu Shi and others have noticed that at this time, this aircraft There is still a lot of fuel in the aircraft. According to the fuel data of this aircraft, nearly three-quarters of the fuel on the aircraft has not been consumed yet.
If you operate according to the normal flight conditions of the aircraft, the aircraft should be basically drained of fuel before landing.
However, on the way back, the Phoenix No. 1 aircraft flew over the Tiangong Science and Technology Base without any movement of oil discharge. This caused Qiu Shi and others to become nervous again.
So he asked Wang Bin: “Mr. Wang! Now the aircraft has more than three-quarters of fuel. Difficulty In your test flight subjects, did you not drain the fuel down?”
After listening to Master Qiu’s words, Wang Bin nodded and said, “Indeed! There was no fuel draining subject in this test flight. And according to our design data, our aircraft, even if it’s in With full fuel, a safe landing is possible. Even if the aircraft is full of fuel, there is no problem with the take-off and landing of the aircraft. It is just that when landing, the distance required to roll is long. Something.”
“What? There really isn’t a subject for draining fuel! Isn’t it too dangerous to land like this? After all, landing an empty plane and carrying a small part of the fuel and carrying most of the fuel for landing are completely different concepts! This is for the plane. A safe landing, but it has a very big impact! If the aircraft has a little failure, the internal fuel is definitely likely to make the aircraft irreversible!
No, Wang Bin, immediately let Zhao Feng drain the fuel inside the aircraft before landing. “Master Qiu said anxiously.
At the same time, the military personnel inside the command center were also very anxious, and they all hoped that Wang Bin would send the crew to release the fuel on the plane.
“Master Qiu! And everyone, I think even if I give the order at this time, it is too late. The plane has already begun to descend!” Wang Bin said.
But no, just when Wang Bin and others were talking, the altitude and speed of the aircraft were already very low, and the aircraft was already facing the base runway, descending rapidly, and Wang Bin and others looked towards the aircraft. At that time, the aircraft was already less than 30 meters above the ground on the runway.
Seeing this situation, neither Wang Bin nor Qiu Shi and others stopped talking, but kept their eyes fixed on the landing plane, because they knew that they must not disturb the pilot at this time. And at this point, even if they ordered the crew to put the fuel in, the crew would not have time to drain the fuel.
Fortunately, the plane landed very smoothly and smoothly, without any abnormalities, and finally landed safely on the runway.
At this time, Master Qiu and the others were obviously relieved, but immediately, he said to Wang Bin with a serious expression: “Mr. Wang! Since the plane has landed safely today, I won’t say anything anymore. However, in the future flight test process, if it is not really necessary, don’t do such a dangerous subject.”
At this time, Master Qiu could not see that the fuel landing this time was one of the flight test subjects arranged by Tiangong Technology, but Wang Bin was afraid that they would object, so in the flight test subjects, he did not pay attention to this. Project, then said.
Wang Bin nodded and said, “Master Qiu, don’t worry! We have collected the data on the plane’s fuel landing. If there are no accidents in the future, we will not conduct such subjects. For example, tomorrow’s test flight project will be There is no such item. And in the test flight operation instructions, it has been clearly stated that after the test flight, the mount must be kept at the minimum alert level before the aircraft is allowed to land.”
With the end of the test flight, the ground crew brought by Tiangong Technology and Qiu Shi immediately towed the aircraft to the aircraft’s special hangar and began to conduct intensive inspections of the aircraft’s condition.
You know, because the flight test time is relatively long, it lasts more than half an hour. At the same time, there are many subjects and the intensity of the test flight is relatively high. In addition, this aircraft will have more subjects and higher intensity tomorrow. Therefore, they must complete all inspections of the aircraft before tomorrow to ensure that the aircraft can be tested smoothly tomorrow, and to ensure that the inspections are in place. There can be no negligence, otherwise, If there is a problem tomorrow, it is absolutely unacceptable to them.
