Test pilot in January to save the two new aircraft: the adventurer called to do science
air force one pilot Yujin Wang
an Air Force flight test groups a large group of test pilots Yujin Wang on April 9 and March 12, two new machines at two different situations encountered on the air parking, his calm, precision operation, not only to overcome the risk, keep the two new aircraft type, but also the successful handling of the Air Force’s first “comprehensive failure resulting in transfer times cut oil empty stop” significant danger. Superiors and experts in aircraft research and development unit successfully disposed of two air he spoke highly of special circumstances, said he made important contributions to model development. This time we spoke with him, hear his views on the flight and understanding of risk.
test is not just a “silly bold”, but rather “scientific adventurer”
test for most people feel very mysterious, And that test is the need for “bold and stupid” type of test pilots to take risks, in fact, this is a misunderstanding of the work test. After a plane designed in full accordance with the designer’s vision is almost not meet the requirements, it is the law: good design and manufacture of prototype test – identify problems – improved design – to test – to find more problems – until all issues are resolved – to determine the performance of qualified, safe and reliable delivery of forces shaping the state. Although the designers through rigorous calculation and design, and through ground testing (wind tunnel, such as hair testing, etc.) to verify the data mode, but often the actual situation with the air of complex least bit of difference, huge mistakes, especially the flight envelope left and right borders. For example: In the structural strength of the “flutter” big table speed test (generally more than 1400 km/h), due to pressure of great speed, once the cause divergence of the “flutter”, less than a second aircraft disintegration may occur, Therefore, in the right circles close to the calculated, often using 30 or even 10 km/hour speed moving forward test point, the end point of each experiment confirmed that no divergence analysis of data trends and other dangers, then the next test point. There are many such examples, such as the engine test bench test to go through the factory – a large assembly of multiple aircraft in flight – in the twin-engine aircraft on the assembly test – finally to be assembled on a single plane flight. Test pilot training, too, you first need to experience some flight test pilot theory training – to get twin-engine aircraft on the flight test experience – after landing stop training after passing the final of the single plane air start test, which requires a scientific system and test flight procedures. Air Force Commander Xu pointed out my mission in the inspection, test pilot should do a “scientific adventurer.” My understanding is the first to have a scientific spirit and scientific method, “silly bold” will only make the aircraft and the pilots into a dangerous situation, and scientific adventure to the premise of ensuring the safety performance of the aircraft and explore the limits.
You experienced many air parking was nervous?
tension, especially in unexpected stop. After stopping the engine, the human heart and mind are fast running, which is a normal physiological response of the emergency, but if you over-react and can not control their emotions on the bad, not as high-speed operation of the CPU cooling measures will be wrong, even Blue Screen of Death, like the human brain, if not “cool” like some people would describe the same confusion, and even a few seconds to several minutes of blank, can not handle any information at that time. Therefore, when the first major special conditions should be “cool”, and then find the key point that the event “the principal contradiction.” After stopping the engine warning lights would all voice and seriously interfere with the pilot’s focus, and therefore need the usual preparation and accumulation (including psychological technology), for example, nine events in higher education, I came in after stopping the reaction The first is putting down a high growth rate of disposal of this critical point, the first to create a good driving conditions, then determine and disposal. Otherwise, the natural response time is still slow, the engine rotation speed will be lower down faster, the air is not conducive to starting the next step, if the driving conditions are poor leading to a car is not successful, will lose more height, into a more dangerous state .
Code in accordance with the provisions of the driver, after stopping height of less than 2000 meters away from the machine should be well prepared and made a forced landing in the March 12 estimate of the disposal of the special circumstances do not slip back when you thought the field jump it?
disposal, while in fact it has been well prepared to jump when you can not save. But the test pilot as a last resort will not easily choose parachuting, skydiving is not only because the abandoned machine would lose a twelve billion of aircraft, more important data may be supposed, or even unable to find a cause and effect model fate. As a test pilot, we know that “The greater the power, the greater the responsibility,” as long as there is the possibility of a trace will do their best to save the aircraft, the preservation of data.
Please talk about your personal resume and flight test experience
Yujin Wang, an Air Force pilot, joined the army in August 1991, 93 years to participate in the flight, the current A total of about 2,500 flight hours, 2002, transferred to a test group to participate in research and test work. Completed higher education in nine, JH 7A, J10, J11 models such as the identification of 10 test flights stereotypes can be said that in 2009 the National Day military parade on the flight all the models are out of my mission, and which I have to fly all aircraft over, I our country proud of the progress of the aviation industry, more accountable for their test flight is part of this team in a proud!
