Flying Leopard fighter test pilot crashed at the expense of Yujin Wang

Xiangtan News Online October 27 (Xiangtan Evening News reporter Wu Hui) in Shaanxi Air Show, driving Flying Leopard fighter test pilot crashed at the expense of the Chinese test pilot Yujin Wang hospital Yazi is Xiangtan. October 26, Yujin Wang Peng Yuguang high school students made contact with us, their eyes Yujin Wang recalled.

Yujin Wang and Peng Yuguang Xiangtan City is the third high school class of 127 students. In Peng Yuguang eyes, high school age not in school Yujin Wang a high profile, and everyone on his right, then people kind, generous, very open field of vision.

in secondary school, Yujin Wang’s idea a bit different, Peng Yuguang said that he likes to play video games, play the best fighting aircraft was a popular game. To play the game, he is often late for class or leave early, but even so, his academic performance has been excellent, always among the top few in class.

1991 years, Yujin Wang and his students into the third year, this year, Yujin Wang and another student cadet success. Therefore, the next period to the third year, was assigned to science and engineering classes Yujin Wang has rarely come to the school class.

cadet success, ten years time, assiduously Yujin Wang became an Air Force test pilot test group. March 12 and April 9, Yujin Wang on two new machines in different situations to test air parking. His calm and precise 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. Higher-level units and aircraft development experts for his successful handling of the air two highly special situation, saying he made important contributions to the development of models.

performances after the accident, news quickly spread, where students have been linked, for students in the group has organized a brief ceremony, a black screen, as Yujin Wang silence. Many users also reprinted Yujin Wang deal with two air parking posts, expressed condolences for his sacrifice.

more line between two blue warriors – two successful test pilot Yujin Wang air handling special situations documentary

aircraft engine air flight safety stop is the “enemy “If air starting is unsuccessful, the pilot and aircraft would cause great risk. Especially for single aircraft, an air-parking for every pilot who is “death in the face.” Even in the ideal situation for an empty slip planes landing at the airport, because parking can not adjust the status of the aircraft throttle, the aircraft is too low will fall on the runway visual, the visual out of the runway is too high, no matter what kind of cases are fatal ! The flight landed as part of the most complex, will have a normal error, not to mention the parking state. Therefore, the disposal of air parking is not only driving skills of the pilot test, but is a severe psychological test pilots.

single parking, air adventure to save the “Eagle”

aircraft quickly jumped to 11,000 meters of altitude, in this area, the sky showing the most moving the blue, particularly quiet, especially purity. Yujin Wang driving as free as the eagle flying aircraft, the fuselage under the layers of clouds, row upon row. 12:35, just to level the aircraft, flying at Mach 0.85, suddenly, the aircraft engine like thunder uttered the “Baoxiang.” Immediately, the engine speed, temperature indicators instantly fell, the plane quickly thrust down, unable to maintain altitude. Yujin Wang at this time of the first reaction is “stop the engine!” His heart “Ko Deng a bit.” As a single plane, air force once lost, the situation will be very dangerous. Transport aircraft such as the large aircraft have greater glide ratio, glide without power also depend on the time for disposal, and such aircraft as the Higher Education 9 In such cases, the aircraft will become a rapid fall of the “lump of iron.” .

as an experienced test pilot, Yujin Wang clear: At this point the aircraft from the airport there are more than 80 km, according to the glide ratio calculation is impossible to go back. The situation is more complex, since this is a new machine has not been finalized, aircraft design is not perfect, the disposal of the test pilot caused a lot of negative factors. At this time in the cockpit of the “stop”, “off”, “hydraulic pressure” and other red, yellow warning lights are all flashing glare of light, and Voice Alarm Systems “mezzo” also continue to use ” gentle “tone and” flat “tone that he prompted various systems malfunctioned. But this time, the light source and the sound feels especially forced Yujin Wang’s “harsh and strident.” They not only spread the test pilot of energy, even serious interference to contact him and the ground commander. Now, he can only rely on himself.

Yujin Wang quickly stabilize their emotions, in a very short period of time thinking about the disposal methods for air first start, and create favorable conditions for the air start. He first putting down a high growth rate of 8000 m the following air starting a high success rate, as the aircraft speed control table 450 km/hour, and has been maintained to 7000 m height. He then concentrate on operating the aircraft at the same time, repeated silently in the hearts of the air start-up procedure. He knows, at this time does not allow him any misuse, because once the mistake, it will cause the engine “rich oil over-temperature”, etc., so the aircraft can not start properly, the engine temperature is increased, but the speed is not rise. This will not only damage the engine, but also to re-start, will add more uncertainty, it is important to lose valuable height.

the best starting time arrived, he did not hesitate to call Kai air starter switches, eyes firmly fixed on the tachometer. Finally, the table began to slowly increase speed, the engine also issued a “huh” sound of the starting rotation, the air starts again from the success! Yujin Wang at this time is still not the effect, he then gently push the throttle operation is very important to slow parking spaces, and finally maintained at 85% throttle the amount of control.

stable state in the plane, Yujin Wang immediately get in touch again with the commander. The accuracy of the ground command system command guidance, he continued descent control the airplane, at 12:48 landed safely at the airport runway. Later, the aircraft manufacturer design your Air Xuwen Jian, deputy chief engineer to hang Yujin Wang’s hand, said excitedly: “You are disposed of properly, to save our plane.” Experts in the issue after the parties conducted a comprehensive analysis, put forward: the problem occurs due to sudden failure of aircraft systems accidentally, accurate and timely and effective disposal of test pilots, not only effectively resolve the risk, also found a part of aircraft design in the presence of defects, aircraft-related system improvements to provide the direct basis for the development of models made an important contribution.

Higher Education 9 China’s aviation development and production of a new generation of enterprise self-financing advanced trainer, once the airplane air start unsuccessful, the consequences would be disastrous. In fact, in the event of a major danger, he could choose a variety of ways and means of disposal, the test pilot for the safest way is to abandon aircraft parachute. However, “The greater the power, the greater the responsibility.” As Yujin Wang said: “Any one test pilots as a last resort, will not abandon aircraft parachute, because once a billion dollars was supposed to not only the equipment, are more likely to be a model of fate!” This awareness has long been become a strong sense of responsibility, each feature in the blood which the Air Force test pilot.

on the air in less than a month before the stop, Yujin Wang has also experienced a more “dangerous” air special circumstances.

startling 900 seconds, the new machine suffered a chain danger

3 12 afternoon, Yujin Wang according to flight plan, the state machine of a new type of class Ι risk subjects the second test flight vehicles flutter. 15:22, departure before the completion of the final examination, Yujin Wang airplane roll, afterburner, vacated, warplanes such as the cosine of an arrow piercing the blue sky, and instantly disappeared in the vast sky.

15 At 1133 hours the aircraft climb to 5000 meters high, the table at this time the aircraft speed of 500 km/hour. At Yujin Wang manipulate the process to level the aircraft, aircraft engine speed suddenly dropped automatically from 85% to 80%. At the same time, appeared on the cockpit screen display “engine parameter adjustment T4 channel failure” of the display, the engine “start” indicator light begins to flash. After about 10 seconds, as the sudden arrival of these failures, as suddenly disappeared. Yujin Wang rule of thumb, the engine may be a problem, he immediately reported to the ground while commanders, while test subjects to stop the action, flying U-turn back to field.

in the back field during the same failure like a “ghost” as many times, and getting worse. In the next 10 minutes, the engine turned up more than 30 consecutive automatic cutting cutting oil when the engine oil after a serious speed below 70% was lower than the height of the slow speed, causing the engine continued to issue over-temperature alarm and 7 times its own air start, start slow speed up to speed after a few seconds and then automatically cut the oil, so keep the cycle. This is a chain danger, but also the Air Force and flight in the history of China’s first “comprehensive failure resulting in transfer times cut oil empty stop,” the major air special situations. As new equipment, either Air Force or flight departments are not related to the experience and methods of disposal. In other words, drivers and aircraft are uncertain, test pilot in order to keep the aircraft to rely on their guts and skill to challenge the real “death,” alone in the huge risks in life to explore and unlock the door to decipher the password.

Yujin Wang reported to the commander at the same time, the rapid decline in the height of the aircraft. As the aircraft away from the field and 40 kilometers, he plans to do a rush at the alternate airport prepared. But his worst fears or lack of occurrence of the aircraft has thrust! In the ensuing years, the maintenance of aircraft survival “rate” is his best glide ratio to get. Aircraft to glide the way to 400 km/hour speed of the table slide the hard ground 30 km distance from the field, but the height of the aircraft at this time only 2,000 meters, the height can not slip back to the field! The alternate runway is shorter, not suitable for landing. How to do?

when danger occurs, remain calm is a good test pilot of the first quality, the only fearless risk, clear-headed, in order to make the right judgments, to choose the most effective method. The regiment had arranged Yujin Wang carried out similar models in the air start special flight, he had done dozens of air starter, air stop flight landing and other subjects, and thus accumulated a wealth of experience, he built more confidence in handling dangerous .

at the moment, he took a deep breath, the brain is the same as high-speed operation of the computer, in front of all the phenomena of a comprehensive analysis to determine. He will break the focus on the engine, the engine speed increased after starting the stage, his first tentative soft fuel door, observe the reaction plane, while closely watching the fast-changing variety of instruments and data, he would like to front of ever-changing variety of information to master status and trends of the aircraft. Ten seconds later, a miracle occurred a short time the engine speed increased to 90%. He seized this rare opportunity to immediately fly the airplane to climb to 3000 meters height. Yujin Wang a little sigh of relief, he was a valuable opportunity to take advantage of this fleeting, as the aircraft gained height of 1,000 meters, then “high” is the life! Suddenly, the engine again cut oil … …

Yujin Wang found that the aircraft away from the field has less than 20 km is a combination of a variety of factors to determine the use of the existing height can slip back to the field. He is also clear that this decision will make him no escape route, or even encounter more complex, but he was determined to bold a try. The reason why he made this decision, not only is he fearless risk, more is necessary to the safety of aircraft back to his strong sense of responsibility! For a new machine and the fate of a model, even if only one in a million could, he would be one hundred percent effort.

aircraft in the downturn, Yujin Wang side of the report commanders, while preparing for the parking landing landing. He first checked the hydraulic system, no fear at all sure, he put down the landing gear in advance, so that all focus on aircraft operation. He was forced to land routes in strict accordance with the height, speed down, and the use of speed brakes, etc. from time to time to amend the aircraft’s speed and position. The ground commander, deputy head of the Li Ji W is transferred out of his emergency landing of all aircraft flights, and prompts him to directly manipulate the head landing aircraft to reduce the gliding distance and residence time of air, landing as soon as possible. At this point, the engine is still repeatedly cutting oil, alarm, deceleration, start, more than to be in the air every second, will increase a risk.

500 meters, 300 meters, 100 meters … aircraft from the runway getting closer, getting lower and lower height, the hearts of the people on the ground have been continuously put up. Fire engines, ambulances already vigilant at the airport on time one seconds ticked past. 15:48, close to the horizon plane finally landed safely in a beautiful gesture. Danger to the successful return from the market place, before and after 15 minutes, a full 900 seconds of time. Among them, every second tremendous risk. He succeeded! Yujin Wang strong in his faith, fearless spirit and excellent technology to create another miracle in Chinese aviation history.

dangerous situation occurs, leaders at all levels are very concerned about, is traveling outside of China Flight Test Institute president Liu repeatedly phoned voters to understand the situation, the test pilot for sympathy. Military leadership requires careful investigation cause of the malfunction, the engine of the same type of survey, follow-up to ensure flight safety. Formed by the investigation team to identify the parties, the danger is due to sum transfer (engine integrated regulator) T4 channel failure due. Investigation team of experts agreed that: the very correct disposal of special situations, especially test pilot to detect and decisively back field, shorten endurance. Subsequently found, then the engine has less pressure oxygen to 1/3, if the field does not return in time is likely to lead eventually not be able to start the engine. Investigation group also put forward: the test pilot to determine the danger is very accurate, comprehensive tune the engine as the core component, there may be short-term recovery in case of power off test pilot is not the temerity, or engine surge, anti-ice and for oil conditioning system will not work, and will lead to other problems, the air in case of accident, with unforeseeable consequences. Members try to save the plane to fly, to save the model.
