In the design of solid propellant rocket motors (SRMs), ignition transient is a strongly unsteady phenomenon including steep pressure variations, convective heat transfer process coupled with combustion chamber internal fluid dynamics. Thus, the above-mentioned phenomenon, due to its complexity has an effective impact on the design process in terms of statistical variability regarding SRM performance. For this reason, a low time-consuming code should be used in order to provide a wide spectrum of statistical performance sensitivity. This paper is intended to provide a simplified physical model to predict the ignition transient phase. The above-mentioned techniques are developed and tested on ROBOOST (Rocket BOOst Simulation Tool) which is a ballistic simulator developed at the Laboratory of Propulsion and Mechanics of the University of Bologna in collaboration with AVIO S.p.a. Simulations results are carried out and discussed.

Abstract

In the design of solid propellant rocket motors (SRMs), ignition transient is a strongly unsteady phenomenon including steep pressure variations, convective heat transfer process coupled with combustion chamber internal fluid dynamics. Thus, the above-mentioned phenomenon, due to its complexity has an effective impact on the design process in terms of statistical variability regarding SRM performance. For this reason, a low time-consuming code should be used in order to provide a wide spectrum of statistical performance sensitivity. This paper is intended to provide a simplified physical model to predict the ignition transient phase. The above-mentioned techniques are developed and tested on ROBOOST (Rocket BOOst Simulation Tool) which is a ballistic simulator developed at the Laboratory of Propulsion and Mechanics of the University of Bologna in collaboration with AVIO S.p.a. Simulations results are carried out and discussed.
