US 2014/0338348 A1 · ROTARY PULSE DETONATION ENGINE

Abstract

This invention relates to devices for discharging high pressure exhaust, and in particular to pulse detonation engines. More specifically, the invention describes a rotary pulse detonation engine having a rotary valve system. The rotary valve includes a generally-triangular rotor having rotor tips within a rotor chamber having trochoid inner end surfaces and side surfaces. The rotor defines three working chambers defined by the rotor tips contacting the rotor surfaces. In operation, the rotor tips move in a circumferential direction around the rotor chamber as the rotor spins. During operation, each of the working chambers will sequentially pass through an intake interval, compression interval, expansion interval, and an exhaust interval to create and detonate compressed fuel air mixtures for effective release to an exhaust chamber and nozzle thereby creating a pulsed detonation sequence.

Dependent claims

A pulse detonation engine comprising:

a rotor operatively contained within an oval chamber, the rotor having at least three rotor tips and a corresponding number of rotor surfaces between each rotor tip, the rotor rotatable within the oval chamber such that each rotor tip is engaged with the oval chamber as the rotor rotates within the oval chamber;
wherein the rotor tips and rotor surfaces define at least three progressing chambers within the oval chamber;
an eccentric lobe on a shaft operatively engaged with the rotor for biasing the rotor tips against the oval chamber;
a fixed gear on the oval chamber for engagement with a corresponding inner gear on the rotor for defining the rotation path of the rotor within the oval chamber;
a fuel injection system operatively connected to the oval chamber;
an oxidizer inlet system adjacent the fuel injection system within the oval chamber;
an ignition system within the oval chamber;
and
an exhaust port;
wherein as the rotor is rotated within the oval chamber, fuel and air are successively mixed, compressed and detonated wherein the resulting detonation force is ejected from the exhaust port.
