Two principal objectives were attained 1 Investigation in depth of certain operating characteristics of the T-burner and 2 Development of a preliminary theory of L instability, treating it as self-excited oscillatory combustion and correlating the nonacoustic instability of a class of PBAAAP propellants by means of the theory. The work consisted largely of early stages of developing a new type of T-burner for studying acoustic instability cylindrical, side-vented chamber burning premixed gases introduced through a permeable frit in one end and of formulating a more general version of the theory of nonacoustic instability. Two problems, are under continuing study, to determine the acoustic admittance of the frit and to minimize chamber-coupled pressure and composition transients in the gas feed system. Author
