JJ-6飞机进入和改出尾旋的操纵规律的研究(二)

THE STUDY OF CONTROL LAWS OF SPIN ENTRY AND RECOVERY FOR THE JJ-6 AIRCRAFT(2)

本文用BACTM理论配合时域动态响应研究JJ-6飞机进入和改出尾旋的操纵规律.文中所用的操纵面是副翼和升降舵。通过计算、分析,确定出可能出现尾旋的操纵区,最后探讨了进入和改出尾旋的机理.

In this paper, the control laws of spin entry and recovery are studied by the Bifurcation Analysis and Catastrophe Theory Methodology (BACTM) and are confirmed by the time history. The control surface used in the control system are an aileron and an elevator. The region occuring spin is determined by using the approach proposed in this paper. Finally, the mechanism of spin entry and recovery are explored.
