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 کاملStudies on the Internal Ballistics of Composite Solid Rocket Propellants Incorporating Nano-Structured Catalysts
This paper deals with the analysis of burn rate using various catalysts of Iron Oxide and determining which gives the higher burn rate with low pressure variation. The Ammonium Perchlorate (AP) was obtained and ground into fine powder with the particle size ranging from 63 to 125 μm. The propellant strands were prepared with proportions by mixing AP with the binder (Hydroxyl Terminated Polybuta...
متن کاملFlow-Structural Interaction in Solid Rocket Motors
This article reviews and summarizes recent work on flow-structural interaction in solid motors. This interaction is important because it can lead to rocket motor failure. In the first part of the document, an idealized model of the failure mechanism is developed to illustrate in simple terms how such an event can occur. In the second part of this article recently published numerical modeling wo...
متن کاملAcoustic-Mean Flow Interaction in Solid Propellant Rocket Motors
There are several sources for pressure oscillations in solid propellant rocket motors. Oscillatory flow field is one of them. Free shear layers in motor flow field cause vortex shedding. End edges of propellant grains and baffle edge in two-segmented motors are samples of such zones. These vortices move from their forming points and strike the field walls. The kinetic energy of vortices change ...
