An Aeroelastician's Perspective of Wind Tunnel and Flight Experiences with Active Control of Structural Response and Stability

摘要

Active controls technology is assessed based on a review of most of the wind-tunnel and flight tests and actual applications of active control concepts since the late sixties. The distinction is made between so-called 'rigid-body' active control functions and those that involve significant modification of structural elastic response or stability. Both areas are reviewed although the focus is on the latter area. The basic goals and major results of the various studies or applications are summarized, and the anticipated use of active controls on current and near-future research and demonstration aircraft is discussed. Some of the 'holes' remaining in the feasbility/benefits demonstration of active controls technology are examined.
