Abstract : The longitudinal mode of combustion pressure oscillations in a rocket moto was investigated. A premixed gaseous type rocket motor was utilized for this work. Experimental findings showed no change in oscillations when the heat transfer characteristics of the injector were varied. Any mechanism for longitudinal oscillations in a premixed gaseous rocket motor based on an oscillatory heat transfer to the injector is inadequate. (Author)
