摘要
飞机在大气中飞行时,会受到复杂的大气紊流的影响,其中以风切变最为普遍。文章分别对有风切变影响和无风切变影响下飞行的飞机建立纵向运动方程,并根据小扰动线性理论,针对低空定常平飞,分析了各自的纵向运动模态特性,为飞机飞行控制研究提供一定的理论依据。
The aircraft will be affected by the complicated atmospheric disturbance, and the windshear is the most prevalent. In this paper, the equation of longitudinal motion under windshear and non-windshear was established. Based on the small disturbance linearization theory, aiming at low altitude steady flight, the characteristic of each mode was analyzed. Then it provided several academic bases on the research of flight control.
