Abstract

The objective of this research was to experimentally study the capability of adaptive material plate actuators to alleviate buffet loads. This investigation involved a single degree-of-freedom wind-tunnel model consisting of a rigid surface and a flexible mount system which permitted only plunge translation. Actuators made of piezoelectric material and affixed to the mount system provided the actuation mechanism for this system. Command signals, applied to the piezoelectric actuators, exerted control over the damping of the system. The closed-loop response, on average, was 32 percent below the open-loop strain response.
