Perspectives in aeroelasticity.

Based on selected topics, the paper is broadly aimed to indicate achievements of the past decade, the state of the art, and trends in aeroelasticity. Topics selected for this end include: brief orientation into the history of the subject, roles of active controls and the concept of aerodynamic energy in load alleviation and in flutter suppression, computerized aeroelastic analysis, aeroelastic effects in stability, aeroelastic optimization, the use of composites, recent applications of lifting surface theory to interfering surfaces and control surfaces, transonic flow considerations, and some problems related to the space shuttle.
