Investigation of LF combustion instability is conducted where mechanism of instability is lag of burning-rate response to pressure disturbances near propellant surface due to temperature gradient just below surface and its interaction with lag in exhausting chamber due to nozzle flow; burning-rate and pressure perturbations are related through closed-loop feedback system analysis; expressions are derived for 2 transfer functions, and instability criterion is developed by application of Cauchy's theorem, resulting in correlation of critical pressure for given propellant and chamber characteristic length.
