在结冰条件下飞行时,飞机的升力下降,临界攻角减小,阻力增大,使得其飞行性能下降。本文根据适航规章CCAR 23 R3的条款内容及相关咨询通告的要求,研究了某单发涡桨轻型公务机在已知结冰条件下的基本飞行性能试飞科目。研究结果对该类型飞机的研制具有一定的参考意义。 When flying under icing conditions, the aircraft’s lift drops, its critical angle of attack decreases, its drag increases, and its flight performance declines. In this paper, according to the provisions of Airworthiness Regulations CCAR 23 R3 and the requirements of the relevant advisory circular, the basic flight performance test subjects of a single turboprop light business jet under known icing conditions are studied. The research results have certain reference meaning for the development of this type of aircraft.
