飞机大迎角飞行稳定性判据分析

 1.引言 随着高机动性飞机的发展,大迎角飞行稳定性日益线引起人们的关注,并各自根据特定的条件作了相应的简化,提出了并种简化适用的大迎角飞行稳定性判据,如急滚机动的Phillips准则、方向发散的动方向稳定性参数m_(y·dyn)~β、横向操纵偏离参数LCDP、以及预测偏离的

FLIGHT STABILITY CRITERIA ANALYSIS OF AIRCRAFT AT HIGH ANGLES-OF-ATTACK

A new synthetic flight stability criterion of aircraft at high angles-of-attack isdeveloped in thispaper by analyzing the operator matrix of 5 degrce-of-freedom motion equations of aircraft after a brief introduction and interpretation of several simplified criteria concerned with the flight stability of aircraft, such as dynamic directional stability parameter mBy.dyn.departure predicting criterion Phillips parameter LCDP which is closely involved with the stability of aireraft at high angle-of att ack .The new eritrion synthesizes all the above simplified criteria, and reveals the relationships among them.
