Abstract:

This paper proposes an improved Angelino method and an improved “Parabola plus Cubic” curve method to design the solidpropellant axial plug nozzle on the assumption of constant velocity drag coefficient for two-phase flow. The performances of the two-phase plug nozzles designed by the improved methods are computed.
