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.

Pressure and density of a gaseous mixture are increased in the process of introducing the gaseous mixture into the combustor of an air-breathing pulse detonation engine employing atmospheric oxygen as an oxidizer. The exit valve 20 able to be opened and closed is provided at the outlet of the combustor 15, an air cooler 12 is provided in the exit of the intake, and density is increased by exchange of heat of the air received at the intake with a coolant in the air cooler 12. Furthermore, by closing the exit valve 20 provided in the outlet of the combustor during the process of loading the gaseous mixture, transition to the detonation process is possible without expansion of the high-pressure high density air obtained by ram-compression at the intake.
200	MULTITUBE VALVELESS PULSE DETONATION ENGINE	PCT/CA2011/050362	2011-06-15	WO2011156923A2	2011-12-22	GOTTFRIED, Kristjan; JUAN, Alejandro
Disclosed herein is a valveless multitube pulse detonation engine including: a plurality of detonation tubes, wherein each detonation tube comprises an independent discharge outlet, and the plurality of detonation tubes interconnected at a common air/fuel mixture intake port. In the disclosed engine, an air and fuel mixture is detonated in the detonation tubes simultaneously, and the common air/fuel mixture intake port minimizes back-pressure caused by detonating the air/fuel mixture by directing multiple reverse shock waves into one another and effectively using the back-pressures as reacting surfaces for one another and effectively reducing the effect of back flowing shock waves moving towards upstream. The detonation tubes may be non-linear, and may have independent discharges. The independent discharges may be coupled to an adapter nozzle terminating in a combined exhaust outlet.
