【摘要】 本文根据飞机偏离运动的特性,利用飞机非线性运动方程组的导算子矩阵研究副翼操纵时飞机闭环稳定性,获得了飞机偏离预测的新判据。通过对6架飞机偏离特性的计算,表明该判据简单有效切实可行,并且与Bihrle判据以及Weissman判据取得了较好的一致。更多还原

【Abstract】 After careful examination of the departure motion of aircraft, a new criterion for predicting departure characteristics of aircraft at high angles-of-attack is put forward in this paper, by analyzing the close-loop stability of aircraft under the control of aileron. The stability is indicated by the analysis of the operator matrix of the nonlinear aircraft dynamic equations. Computations made on six aircraft departure characteristics show that the new criterion is good and sound, and agrees well with Bihrle criterion and Weissman criterion.更多还原
