Experimental and theoretical research on aeroelastic stability and response problems has been carried out this past year in several areas. A major portion of the research centered around an investigation on the stability of thin cylindrical shell structures subjected to a subsonic compressible flow environment. Other studies were concerned with the active suppression of interfering lifting surface flutter phenomenon and the active control of rapid transit system response for improving ride quality. Studies were also conducted on the suppression of stall and stall flutter phenomenon. A brief description of this research is presented herein.
