Testing of an active smart material system for buffet load alleviation

摘要

This paper details the design, fabrication, and ground-testing of a full-scale prototype Buffet Load Alleviation system for the F/A-18, with an emphasis on ground-test results. ^The system controls vibrations using piezoelectric strain actuators and active feedback control. ^In the tests, attenuation of greater than 50 percent of the rms buffet response was demonstrated using two channels of control. ^(Author)
