Closed circuit rocket motor has exhaust from pump turbines fed through injector into expansion nozzle of rocket motor

摘要

The closed circuit rocket motor has the propergol feed pumps driven by turbines with closed circuit operation. The exhaust from the turbines is fed to an inlet for parallel flow to the expansion nozzle (3) with the main exhaust. The inlet has an injection nozzle (2) with a connection for the turbine gases into the expansion section of the nozzle. An inlet turbine (1) is mechanically connected to the injector.
