Abstract:

Local accelerations and airframe loading due to both rigid body and structural dynamics concern pilots and designers of aircraft. Gust response adversely effects system mission effectiveness by degrading structural fatigue life, crew and passenger comfort, handling qualities, and weapon delivery accuracy. Aircraft trends and developments that have precipitated this problem area are discussed. Various control system philosophies and techniques, both active and passive, that have been proposed and investigated as a means for controlling structural dynamic response are discussed. The use of suitably located, sized, and phased control force inputs can greatly increase the closed-loop damping ratios of the lower frequency structural modes, alleviating the above problems. Such structural dynamic response control systems must be compatible with other sub-systems such as terrain following and rigid body stability augmentation. Author
