RPA: Design Tool for Liquid Rocket Engine Analysis

RPA (Rocket Propulsion Analysis) is a design tool for the performance prediction of the liquidpropellant rocket engines. RPA is written in Java and can be used under any operating system that has installed Java Runtime Environment (e.g. Mac OS ® X, Sun SolarisTM, MS WindowsTM, any Linux etc). The tool can be used either as a standalone GUI application or as an object-oriented library. This docu...

The Blacklight Rocket Engine

Executive Summary This report summarizes the final project results for the period of May 1, 2002 through November 30, 2002 for the NIAC CP 01-02 Phase I study, "The BlackLight Rocket Engine". The objective of the Phase I study was to assess the potential of low pressure, mixed gas hydrogen plasmas (i.e. the BlackLight Process) toward the development of high performance space propulsion systems.

SMORE Phase 2: An Upgrade in Valve Systems & Startup Procedure for A Small Methanol Oxygen Liquid Rocket Engine

Nonlinear theory of combustion stability in liquid rocket engine based on chemistry dynamics

Detailed models of combustion instability based on chemistry dynamics are developed. The results show that large activation energy goes against the combustion stability. The heat transfer coefficient between the wall and the combust gas is an important bifurcation parameter for the combustion instability. The acoustics modes of the chamber are in competition and cooperation with each other for ...

Engine-Level Simulation of Liquid Rocket Combustion Instabilities Transcritical Combustion Simulations in Single Injector Configurations

Detailed understanding of turbulent combustion in liquid rocket engines (LRE) requires an ability to predict the coupling between the transient features, acoustics, vortex/shear layer dynamics and the unsteady combustion heat release. Conventional and ad hoc models that mimic or match one set of conditions but fail in another test case cannot be used for reliable predictions. This paper present...
