Active flutter suppression, which is a part of the group of flight vehicle technologies known as active controls, is an important contributor to the effective solution of aeroelastic instability problems when they pop up late in the development of a new aircraft or, if used from the start of the design process, it is a key element in multidisciplinary design optimization that could lead to Cited by: North Atlantic Treaty Organization Advisory Group for Aerospace Research and Development Structures and Materials Panel Active control systems for load alleviation, flutter suppression and ride control by Impact of acoustic loads on aircraft structures = Impact des solicitations acoustiques sur les structures d'aéronefs by Specialists. Examples are gust load alleviation or active flutter suppression concepts, where control surfaces are actively deflected to counteract loads or create unsteady aerodynamic damping--to I. forces. One reason why these systems did not become common practice, is the insufficient static aeroelastic. Gust load alleviation has become an integral part of aircraft design to significantly decrease the impact of atmospheric turbulence on aircraft loads, handling qualities and also passenger comfort.

In one embodiment, the controlled plate-like structure is an adaptive lifting surface, which is controlled for maneuver enhancement, flutter and vibration suppression and gust and load alleviation.
