在飞行中的

Armstrong August 5, 1930 Wa Pake was born in Ohio in the United States reached the city of his childhood learning seriously, when the ideal is to grow the pilot, 14-year-old began to receive flight training, 16-year-old pilot certificate to obtain ,1949-1952, he became the Navy The youngest pilots. Armstrong in July 1953 expiry of the service backward Pardew Aviation University of Technology, after graduating from Edwards Air Force Base in any test pilot, later took part in the X-15 rocket plane's flight plan had been 6 flight, highest altitude reached 60,000 meters. In September 1962, a rigorous selection process, Armstrong became the first civilian from the pilot in the selection of one of the 2 astronauts, space industry and from forged a bond.

The Airport Security in the work of the Airport so that he is the head of the bird pest problems because of Zhangjiajie Airport is located in the mountains, birds at the airport, air space flight in particular, the safety of aircraft flying will be very much affected, and the bird work for the Airport Security Field Services team that is a major problem, how can we solve this problem to ensure flight safety?

而机场保障部工作中最让他头痛就是机场的鸟害问题，由于张家界机场位于山区，鸟类在机场空域飞行特别多，对飞机的安全飞行是有很大影响的，而驱鸟工作对于机场保障部场务队来说就是一大难题，如何才能解决这个难题保证飞行安全呢？

First, the angular velocity function and maneuver load for certain maneuver flight (including hover, dive-hike and these two combined) are set up. The simulation results of the vibration of double-disk rotor system with cantilever supported on rigid bearings show that rotor would be apparently deformed under maneuver load. Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related.

Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related. Then, SFDs are introduced into typical Jeffcott rotor system. The whole system will be statically displaced in maneuver flight and the nonsynchronous components of oil force appear in the response of rotor system.
