ROTARY PULSE DETONATION SYSTEM WITH AERODYNAMIC DETONATION PASSAGES FOR USE IN A GAS TURBINE ENGINE

摘要

A pulse detonation system for a gas turbine engine having a longitudinal axis extending therethrough includes a rotatable cylindrical member having a forward, an aft and an outer circumferential surface. At least one stage of circumferentially spaced detonation passages is disposed through the member. Each passage includes: a leading portion adjacent the forward surface and a trailing portion adjacent the aft surface, each having a centerline at an angle relative an axis parallel to the longitudinal axis and a middle portion having a centerline with constantly changing slope connecting the leading and trailing portions. A shaft is rotatably connected to the member and a stator is spaced relative the forward surface and a shaft portion. The stator includes at least one group of ports alignable with the leading portions as the member rotates. Detonation cycles interact with combustion gases in the passages to create torque which rotates the member.
