ESTIMATION OF THE MAXIMUM POSSIBLE PRESSURE IN AN OXYGEN-HYDROGEN ENGINE,

Abstract

An analytical method is presented for estimating approximately the maximum possible pressure in an engine chamber using a closed system with a turbopump drive. Hydrogen, which is heated in the chamber cooling circuit, is used as the working medium. Calculations indicate that at the actual efficiency of the pumps and the turbine, it is difficult to achieve a pressure higher than 40-50 ata in the engine system. This limitation is mainly due to the low hydrogen heating temperature values (200-270K) in the cooling circuit. (Author)
