Abstract
A positive displacement rotary motion device including in one example a pulse detonation device. Also; an indexing system for a rotor assembly where in one example the indexing system regulates the rotational location of drive rotors. In one example the rotors are configured to rotate about a shaft.
Claims18
A pulse detonation device comprising:
- a detonation region,
- a mixing chamber in fluid communication with an air transfer line that provides preheated air from a heat transfer system, wherein the heat transfer system provides an air conduit for air to transfer around the detonation region, extracting heat therefrom,
- the mixing chamber configured to receive preheated air from the air transfer line that are in communication with the heat transfer system, the mixing chamber further in communication with a fuel injector,
- a diffuser configured to receive a fuel air mixture from the mixing chamber,
- the detonation region downstream from the diffuser, where the detonation region is configured with a detonation location that provides sufficient activation energy to detonate the fuel air mixture therein,
- whereby expanding gas of the detonated fuel air mixture travels down the detonation region to an exit location.
