Abstract
A unique seal for a wave rotor disk engine is disclosed herein. The seal is operable for sealing a region between a rotor and a rotor casing. The seal is spring loaded and will engage with the tip of the rotor to reduce pressure loss within the wave rotor disk engine.
Claims9
A method comprising:
- injecting an air/fuel mixture into a hub region of a rotating rotor in a wave rotor disk engine;
- compressing and combusting the air/fuel mixture within a plurality of combustion channels formed between adjacent radial vanes of the rotor;
- sealing combustion exhaust working fluid flow between a rotor tip of the rotating rotor with a movable seal member proximate a seal region of a rotor case;
- flowing pressurized combustion working fluid through a rotor exit region of the rotor case;
- and
- wherein the sealing includes continuously engaging the movable seal member by passively biasing towards the rotor tip during all operation of the wave rotor engine.
