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 کاملResearch of Double Mode Ultrasonic Testing in Multi-layered Adhesive Structure of the Solid Rocket Motor
In inspecting steel-rubber multi-layered structure, shielding of steel layer and intense attenuation of rubber layer result in ultrasonic echo from the interfaces of the deep layers being very weak. In order to overcome the difficulty, the double mode testing method is put forward. This method synthesizes the characteristics of transverse wave and Lamb wave testing. In the double modetesting tr...
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...
