Abstract:

This work produced new and better tools for predicting delivered nozzle performance for very high area ratio liquid propellant rocket engines. The motivation for this work is the current interest in space propulsion systems and the high impact that delivered performance has on system design. Design margins can be significantly reduced if the accuracy and reliability of predictive procedures is improved. Two computer programs were developed under this effort. The first of these programs was an extension to the JANNAF standard TDKBLM code. The second code, called VIPER, was a Parabolized Navier-Stokes solver with finite rate chemistry. An experimental plan to validate the predictive capabilities of the two codes was also formulated. Comparison of both TDKBLM and VIPER to available data shows excellent agreement.
