摘要
针对动态偏离敏感参数(CnβDYN)和侧向操纵偏离参数(LCDP)无法预测飞行器在大侧滑角飞行条件下偏离失稳特性的不足,推导建立了大攻角、大侧滑角条件的飞行器动态偏离判据和操纵偏离判据,指出该判据包含了飞行器的所有飞行状态,能够更精确的反映系统的静稳定性需求,可作为一种通用的预测偏离失稳的判据,并对某再入飞行器应用新偏离稳定判据,进行了偏离稳定性分析。
The dynamic departure susceptibility parameter（ C_nβDYN） and lateral control departure parameter （LCDP） are less accurate in predicting departure susceptibility with the condition of large_angle of sideslip. A new type of all stated departure susceptibility criteria with the condition of largeangle of attack and large_angle of sideslip is presented, which is considered as the generalized departure prediction indicator. Regarding the more detail of flight states included, the more accuracy of static stability is showed for the complete system. Also the new departure susceptibility criteria is applied in the analysis of re-entry aerocrafi departure susceptibility.
