Lateral-directional stability analysis and control for the symmetry plane Aircrafts

摘要

This paper is concerned with the problem of the divergent oscillation with aileron-only maneuvering control. By investigating the movement process and physical characteristics, the phenomenon of the divergent oscillation with the normal use of aileron is particular discussed, and a new additional prediction criterion is achieved from theoretical derivation. The merit of the proposed prediction criterion lies in it further improves the accurate of the closed-loop stability criterion, which provides the basis for the design of the aerodynamic configuration and control system. Finally, some state points along the flying track of an aircraft are provided to illustrate the accuracy of the prediction criterion.
