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 Quasi-Steady Solid Rocket Internal Ballistic Behaviour
The ability to predict with some accuracy a given solid rocket motor’s performance before undertaking one or several costly experimental test firings is important. On the numerical prediction side, as various component models evolve, their incorporation into an overall internal ballistics simulation program allows for new motor firing simulations to take place, which in turn allows for updated ...
متن کاملHigh-pressure Burning Rate Studies of Solid Rocket Propellants
Increased rocket motor performance is a major driver in the development of solid rocket propellant formulations for chemical propulsion systems. The use of increased operating pressure is an option to improve performance potentially without the cost of reformulation. A technique has been developed to obtain burning rate data across a range of pressures from ambient to 345 MPa. The technique com...
متن کاملبررسی و شبیه سازی اثرات شتاب چرخشی و طولی بر بالستیک داخلی راکت سوخت جامد
In this study, effects of longitudinal and rotational accelerations on the Internal Ballistic Solid Propellant Rocket are investigated. First, a quasi one-dimensional flow is considered to drive governing equations. By assuming semi- permanent flow and neglecting heat transfer through the walls, at each time increment the governing equations are integrated along the length of motor. Then, using...
