Abstract: An exhaust eductor system includes a primary exhaust nozzle configured to transport an active flow stream; and a mixing duct at least partially surrounding the primary exhaust nozzle and configured to transport a passive flow stream that is entrained by mixing with the active flow stream from the primary exhaust nozzle. The mixing duct has an interior, and a baffle on the interior of the mixing duct is configured to prevent the mixed flow streams from exiting the mixing duct.

Abstract: An inertial inlet particle separator system for a vehicle engine includes an inertial inlet particle separator and an adjustment mechanism. The separator includes a fluid inlet coupled to a scavenge channel and to a clean channel such that a first amount of fluid passing through the fluid inlet enters the scavenge channel and a second amount of fluid passing through the fluid inlet enters the clean channel. The scavenge channel is defined by a first wall and a splitter, and the clean channel is defined by a second wall and the splitter. The splitter and the second wall are stationary with respect to each other. The adjustment mechanism is coupled to the inertial inlet particle separator and configured to adjust a size of the scavenge channel. Although not necessarily, the adjustment mechanism may also be coupled to the scavenge fan speed.

Abstract: A gas turbine engine (10) incorporates a particle trap (46) that forms an entrapment region (73) in a plenum (24) which extends from within the combustor (18) to the inlet (32) of a radial-inflow turbine (52, 54). The engine (10) is thereby adapted to entrap particles that originate downstream from the compressor (14) and are otherwise propelled by combustion gas (22) into the turbine (52, 54). Carbonaceous particles that are dislodged from the inner wall (50) of the combustor (18) are incinerated within the entrapment region (73) during operation of the engine (10).
