Integrated propulsion plant with at least a ramjet and a scramjet operational mode

摘要

The engine is configured such that it is capable of operating either as a ramjet or as a supersonic combustion ramjet, (scramjet). The engine has a main motor system with an air intake (3), a fuel injection chamber (5), a combustion chamber (8) and an exhaust nozzle (4). It incorporates a storage system (10) for air deflected from the main flow (F) in the ramjet mode, and a second combustion system (11) for burning a proportion of the fuel with the stored air in the scramjet mode. The storage system has an air cooler and liquefier (12) in the form of a heat exchanger cooled by the engine's fuel or an auxiliary fluid, and a tank (R2) for storing it. The second combustion system has an auxiliary combustion chamber (14) and exhaust nozzle (15).
