Abstract : This report summarizes the main accomplishments of a three-year research program supported under AFOSR Grant No. F49620-93-1-0177. The main objective of this program was to investigate active suppression of detrimental combustion instabilities in chemical rockets by a controlled, secondary, combustion process. The program consisted of parallel theoretical and experimental efforts; the former developed the theoretical foundation of the investigated control approach and the latter developed a small scale, actively controlled, gas rocket setup that was used to guide the development of the investigated active control system and demonstrate its effectiveness.
