The experiments conducted were designed for studying the factors promoting combustion pressure oscillations in rocket motors burning either premixed or unmixed gaseous propellants. Inves tigations were conducted for determining the effects of combustion chamber geometry, the chemical differences in the propellants, and also the effects of several injection variables. Auxiliary studies were conducted regarding the effects of baffles located in the combustion chambers, and the applicability of linear theories to combustion instability phenomena. Author
