Nonsteady propellant combustion and chamber flow behavior, particularly as they relate to combustion stability and aluminized propellant combustion are being studied. The first part of the study is centered around the modulated throat rocket motor which is being developed to investigate the dynamic responses of high performance rocket motors in which externally excited longitudinal pressure and velocity waves produce coupling with propellant combustion processes. Transfer functions between the measured head-end and nozzle-end pressures produce gain and phase information in the vicinity of the first 3 harmonics.
