摘要： An air intake structure for a nacelle of an aircraft is disclosed having an air intake lip with a U-shaped section open towards the rear, an acoustic panel that extends the air intake lip towards the rear and on an inner side, an outer panel extending the air intake lip towards the rear and on an outer side, and a rear strengthening frame fixed between the outer panel and the acoustic panel, where the rear strengthening frame partly defines an inner volume that is immediately in front of the rear strengthening frame. The air intake structure comprises an impact absorber element positioned in the inner volume and the impact absorber element assumes the form of a structure that is deformable during an impact and that is at least partially filled with a fluid. The impact absorber element is a flexible shroud filled with a pressurized gas.

摘要： A debris deflector for a jet engine. The debris deflector includes a housing having a base and a nose, wherein the housing tapers radially inwardly from the base towards the nose, such that the nose can deflect debris away from the housing. The housing includes a flexible shroud that extends between the base and the nose, such that the housing can selectively move between a collapsed position and an extended position, such that a linear distance between the nose and the base is less when in the collapsed position. A fastener is disposed on the base to removably secure the housing to a jet engine cowling. The debris deflector is useful for deflecting debris, such as wildlife or small aircraft, away from the jet engine during flight.

摘要： An air-inlet duct includes an outer wall, an inner wall, and a splitter. The splitter cooperates with the outer wall and the inner wall to establish a particle separator which separates particles entrained in an inlet flow moving through the air-inlet duct to provide a clean flow of air to a compressor section of a gas turbine engine.

摘要： An air supply plenum for an engine, the plenum being disposed upstream of an air intake of the engine, the air intake being provided in a casing of the engine. The air supply plenum includes a first lateral wall and a second lateral wall which together form a conduit in which an air flow flows as the engine functions. Each lateral wall includes a step which forms a transverse recess relative to the direction of the air flow in the air supply plenum, such that an aerodynamic separation occurs in the step when the engine is operating.

摘要： An inlet air filtration unit for a gas turbine includes an inlet filter house having an upstream surface through which air is ingested. A plurality of weather hoods is secured to the upstream surface. A wave-generating system is installed on or proximate to the plurality of weather hoods, the wave-generating system emitting waves that deter pests from the inlet filter house. A method of deterring pests from entering an inlet filter house of an inlet air filtration system is also provided. The method includes: installing a wave-generating system proximate to or on a weather hood on an upstream surface of the inlet filter house; and energizing the wave-generating system to produce energy waves across the upstream surface of the inlet filter house.

摘要： An inlet for a turbofan engine, including an inlet wall surrounding an inlet flow path. The inlet wall extends axially from an upstream end to a downstream end adjacent the fan. The inlet wall has a shape defining a plurality of teeth circumferentially spaced around the inlet. The teeth extend axially and project radially inwardly toward the central longitudinal axis. A central portion of the inlet flow path has a cross-sectional dimension measured diametrically between opposed teeth, the cross-sectional dimension varying along the axial direction. The central portion defines a geometric throat at a minimum value of the cross-sectional dimension. The inlet wall is shaped so that the geometric throat is axially spaced from the upstream end and the downstream end. A gas turbine engine and a method of shielding tips of fan blades from impact by an object having a predetermined minimum dimension are also discussed.

摘要： An inlet frame and a method of additively manufacturing the same are provided. The inlet frame includes a forward annular body spaced apart from a rear annular body to define an inlet passageway in fluid communication with a compressor inlet. The inlet frame may define integral wash manifolds and discharge ports for directing a flow of wash fluid directly through the compressor inlet. In addition, inlet frame may define one or more integral annular heating plenums in fluid communication with a hot air source for heating regions of the inlet frame that are prone to icing conditions.
