Abstract

A one-dimentional performance analysis code has been developed at eh Laboratoire de Combustion et de Detonique to predict the thrust in the thermally choked ram accelerator propulsion mode. This code includes the real gas effect in steady calculations and incorporates the following equations of state: ideal gas, Boltzman, Percus-Yevick (PY) and Becker-Kistiakowsky-Wilson (BKW). The code was validated against key experimental data from representative experiments at the University of Washngton 38-mm-bore facility. The predicted thrust and valicity agree well with experimental measurements. The present paper provides details about the algorithm of the calculation in the thermally choked propulsion mode.
