Real-time Impact Control of a Solid Rocket Motor Stage during Launcher Ascent
Unlike a liquid propellant stage which allows stopping the thrust at any time during the flight, when a solid rocket motor is used on a Launcher upper stage, the impact zone can be very large due to the atmospheric and propulsive dispersions on the current stage and the previous stages. In this case a stage impact control is required. In this study, an active impact control strategy is presente...
متن کاملOne 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 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 ...

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...
