Virtual prototyping of solid propellant rockets

cerns in rocket motor design because of the enormous cost of typical payloads and, in the case of the Space Shuttle and other manned vehicles, for the crew’s safety. In the spring of 1999, for example, a series of three consecutive launch failures collectively cost more than US$3.5 billion. The most notorious launch failure, of course, was the tragic loss of the Space Shuttle Challenger and its...

Integrated Simulation of Solid Propellant Rockets

This paper presents an overview of research activities at the Center for Simulation of Advanced Rockets (CSAR) at the University of Illinois at Urbana-Champaign. CSAR is one of five university-based research centers funded by the U. S. Department of Energy as part of the Accelerated Strategic Computing Initiative (ASCI). The purpose of ASCI is to advance the state of the art in computational si...

Green Propellant: A Study

The present study focuses simply on propellants which are environment friendly i.e. Green propellants. In Propulsion Systems, there are two ingredients burned together which are fuel & oxidizer and the resultant energy is used to propel the system. In composite solid rocket propellants, Ammonium perchlorate (AP) is being used extensively which has its own disadvantages i.e. HCl release during i...

Acoustic-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 ...
