ABSTRACT:
A hydrogen fueled jet engine for hypersonic aircraft. The compressor of the jet engine is driven directly by a dual-acting rotary piston engine. Heated, high pressure hydrogen is delivered to the rotary piston engine for expansion therein. The crankshaft of the rotary piston engine is attached directly to the air compressor of the jet engine. The power from the expanding hydrogen drives the air compressor of the jet engine. After the hydrogen is expanded to produce power, the hydrogen is burned as fuel.
