One Dimensional Internal Ballistics Simulation of Solid Rocket Motor
An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...

متن کاملScale Effects on Solid Rocket Combustion Instability Behaviour
The ability to understand and predict the expected internal behaviour of a given solid-propellant rocket motor under transient conditions is important. Research towards predicting and quantifying undesirable transient axial combustion instability symptoms necessitates a comprehensive numerical model for internal ballistic simulation under dynamic flow and combustion conditions. A numerical mode...
متن کاملEarly Detection of Solid Rocket Motor Case - Breach Failure ∗
This paper describes work on early detection of space launch vehicle failures that could lead to loss of control during ascent. The particular focus is on the Solid Rocket Motor (SRM) comprising First Stage of the Crew Launch Vehicle (CLV). Some of the most important failure modes leading to loss of vehicle control are caused by hot gases ejected from the SRM combustion chamber through a case b...
