摘　　要：本文研究了以不同质量流的动量理论导出的动力入流的[L]阵,以此计算了旋翼操纵导数,从计算与实测的比较中得到研究[L]阵的简单方法。Different L matrices in dynamic inflow model are derived from momentum theory accounting for different mass folw. The in- fluence of defferent L matrices in ground res- onance is reviewed. Rotor control deriva- tives are calculated accounting for dynamic inflow with different L matrices. It is indi- cated that comparison analysis of the meas- ured and the predicted data of rotor con- trol derivatives is a simple method to investigate the influence of different L matrices.
