Pulse Mode Performance Model.

Abstract : Development of a computerized pulse mode performance model is described, consisting of three distinct technical phases: model formulation, model programming, and model evaluation. The model was formulated and coded for digital computer solution to accurately simulate pulse mode performance operation of liquid bipropellant attitude control engines. The model consists of three primary subprograms that are fully integrated. Sample output data from the computer model are presented and discussed. Model evaluation consisted of conducting many computer runs (modifying the model as required) that simulated the performance of two rocket engines for which performance parameters and characteristics were known from hot-fire tests.
