November 15, at the 11th Dubai International Airshow, a new generation of China’s own R & D L15 advanced trainer aircraft made an excellent flight performance, causing a strong reaction. This is the L15 following the 2008 Zhuhai air show to air show again in the form of public appearances, but also the first time in foreign countries L15 for flight performances, and became the only one of China’s aviation industry in-kind exhibition of aircraft.
14:48 local time, from two Chinese super test pilot Mr Yeung, ZOU Jian-guo driving L15 advanced trainer aircraft to accelerate the pace of take-off roll to the ground from the ground and began to show in a foreign-made models of higher education to performance.
First, going through a horizontal “8″ fly. Aircraft from the ground, direct access to up turns to adjust the position, and began the next horizontal “8″ flight to demonstrate their excellent vertical mobility. Suddenly, L15 height has risen sharply and the aircraft rose to peak altitude of about 900 meters, and then roll out a 180-degree inverted dive changed to accelerate the decline in aircraft dropped a beautiful arc and change to re-enter up gesture, the following will be in the opposite direction to complete the next horizontal “8″ moves the second half.
Subsequently, the aircraft straight and level flight at about 200 kmh-pass field, showing a good low-speed flight characteristics. Thereafter, L15 smooth completion of a full two weeks in a row roll-pass field flying, inverted pass field, rolling a 180-degree turn to inverted flight, vertical rise in motor as well as in reduced vertical height of 200 meters after the increase in flight demonstrations.
L15 advanced trainer aircraft circled low from time to time, sometimes suddenly straight, in the vertical flight, L15 as if the train has already left pierce straight into the sky, reaching an altitude of 900 meters, fully demonstrate its superior vertical mobility. Last L15 landing a small airline based flight show a perfect curtain call. The audience responded with warm applause to celebrate L15 advanced trainer wonderful success of the flight performance.
The flight performances also fully demonstrated the excellent L15 vertical mobility, horizontal mobility, high angle of attack characteristics and low-speed flight characteristics and so on, tens of thousands of spectators from around the world witnessed the L15 machine Excellence grace of higher education, and Dubai air show flight performances added touch of beautiful scenery.
L15 flight performances came in the United States F-16 aircraft, after performances, behind in Italy before the M346 advanced trainer aircraft, which is in this Air Show to compete directly with the L15 an advanced trainer aircraft. Since then, the world’s most advanced F-22 aircraft flight demonstrations. L15 is the mainstream media to become the current Dubai Airshow Air Show, one of the three stars, they are the U.S. F-22, Europe’s “Typhoon (Typhoon)” China’s L15.
L15 advanced trainer aircraft for the Air Industrial Hongdu independently developed a new generation of advanced jet trainer, a successful maiden flight in March 2006, 2008 and 2009, respectively, to achieve 03 and 05 prototype first flight. Participated in the Dubai Air Show, the L15 advanced trainer for advanced trainer (AJT) state test prototype, equipped with an AI-222K-25 non-afterburning turbofan engine. After hundreds of sorties were flown to adjust flight tests, AJT state theory of the flight envelope has reached the boundary, the system works normal and stable, and has been transferred to flight test phase of the design identified. At present, the aircraft industry Hongdu are actively engaged in fighting L15 induction training (LIFT) the state trial work, the status of aircraft will be equipped with AI-222K-25F afterburning turbofan engines, to further enhance the L15 motor characteristics.
L15 advanced trainer aircraft in order to ensure the smooth progress of the Dubai air show performances, as early as the beginning of the Industrial Air division will be organized in defense aircraft industry Hongdu other units to actively start the preparatory work of exhibitors, from the air show profiles, transitions route to ground maintenance, technical support, pilot training and other aspects to develop a detailed program. In October, L15 off a new round of flight height, according to the Dubai air show air show program, completed in China in more than 20 flight drills, constantly optimize the flight parameters during the flight to ensure that each action is done precisely in place to so that flight profile can be both a very strong view of the safety requirements to meet the airshow scene. In addition, the transitions in Dubai for the mission requirements of the transition function test flight, the aircraft successfully laid a solid foundation for participating.
It is learned, L15 flight test stage in the research and actively participated in major exhibitions at home and abroad. 2008 Zhuhai Airshow, L15 for the first time in an open air show in the form of a new appearance, and flying 13 sorties a row, becoming the Zhuhai Airshow, one of the most dazzling star. Subsequently in this year’s model and flight simulator in the form of participation in the Paris Air Show, Moscow, exhibitions and so on, causing a strong reaction.
