摘要： A tailpipe for a gas turbine engine has a cylindrical portion and lobed portion. The lobed portion extends a length X and has a plurality of circumferentially disposed peaks and valleys. Over at least the first 30 percent of length X, the radius of the each valley is greater than the radius of each peak and is greater than 10% of the equivalent diameter DE. Also, the effective flow area at the end of the lobed portion is greater that the effective flow area at its beginning. The cylindrical portion includes a straight portion and a canted portion.

摘要： The present invention provides a means for inducing (educting) a “passive” secondary flow stream using an exhaust eductor system including a primary exhaust nozzle designed to transport an active flow stream and a plurality of tabs extending from a rear perimeter of the primary exhaust nozzle. Each of the tabs is designed to be bent at an angle in relation to the primary exhaust nozzle. An exhaust mixing duct is positioned around the primary exhaust nozzle that is designed to transport a passive flow stream to the active flow stream where the plurality of tabs create a streamwise vorticity to enhance the mixing of the active flow stream and the passive flow stream.

摘要： A compact turbine engine exhaust gas noise suppressor has a housing having a first chamber, a second chamber having an outlet and communicating with the first chamber through a transfer passage, and a third chamber communicating with the first chamber through a perforated dividing wall and having a resonant sound attenuator positioned therein. A sound absorbing member is positioned in the second chamber to create therein a serpentine flow path extending between the transfer passage and the outlet. The exhaust gas noise is attenuated by flowing the exhaust gas into the first chamber through a duct into which ambient cooling air is educted, and then forcing the exhaust gas outwardly through the serpentine flow path.

摘要： An inlet door assembly for reducing air pressure loss and enhancing performance of an auxiliary power unit (APU) contained within an aircraft housing is provided. The inlet door assembly includes a duct and a diffuser. The duct, which is configured to be movably coupled to an aircraft and to move between open and closed positions, has a flow passage extending therethrough. Air external to the aircraft flows through the duct while it is in the open position, but not while it is in the closed position. The diffuser is coupled to the duct and configured to move therewith. The diffuser has a passage extending therethrough that is in fluid communication with the duct flow passage, and is configured to diffuse the air that flows therethrough.

摘要： A radial inflow particle separator includes a pair of axially and radially spaced curvilinear walls cooperatively defining a circumferential flow path leading radially inwardly and axially to an engine. Preferably, the particle separator is employed with a turbine engine which is operated at times in an environment laden with dust and particulate matter. Such an environment is typically encountered by a turbine engine of a helicopter, or off-road vehicle. The particle separator provides dust and particulate control features including aero-inertial, particle trajectory, particle boundary-rebound, and scavenge flow tailoring to achieve a dust and particulate separation efficiency as good as or better than the best conventional axial-flow particle separators. This particle separation effectiveness is achieved in a radial inflow particle separator which is smaller and lighter in weight than axial flow devices, and which packages advantageously with the essential structures of a turbine engine.

摘要： An auxiliary power unit (APU) compartment air inlet system seals, via one or more inlet doors driven by a single actuator, an APU compartment, and isolates the APU inlet and cooling system inlets from each other. The system includes either one or two inlet doors, depending on the number of ram air inlets formed in the APU compartment. In either instance, however, a single actuator is used to move the inlet door(s) between open and closed positions.
