Abstract : An integral closed loop stability model for liquid propellant rocket engines is presented. The basics of the analytical approach, which leads to a set of integral equations to be solved successively, essentially following Picard's method, are discussed. The aspects of the stability problem which have been studied using the approach are reviewed. There include combustion distribution, acoustic absorber effects, nonlinear wave propagation effects, injector face baffles, and velocity and pressure sensitive combustion responses. The types of stability predictions possible with the approach are discussed and some typical results of calculations exemplifying them are given.
