    摘要: An hydraulically-pivotable inlet ramp with box-like shaped cross-section for supplying air into engines of supersonic or hypersonic airplanes. The inlet ramp, comprised of a plurality of relatively movable elements, can be adjusted into a number of different positions to optimize air flow under various mach conditions, as well as control a boundary air layer inlet.

    摘要: A mixed compression inlet having a forward ramp, an aft ramp, and a slot therebetween is disclosed. The aft ramp is coupled to the inlet to permit both fore-aft movement and rotational movement. The geometric throat of the inlet is located at the leading edge of the aft ramp. The slot opens into a plenum chamber. A vent permits air to exit from the plenum chamber. The pressure in the plenum chamber is maintained approximately equal to the pressure on the aft portion of the forward ramp. A servocontroller receiving input from pressure sensors of the forward ramp and in the plenum chamber controls the position of a vent door to ensure that the proper pressure is maintained within the plenum chamber.

    摘要: A construction is provided to aerodynamically affect a jet engine nacelle in its intake lip area primarily by forming and pivotally arranging flaps on a radially outer circumferential sector of the intake lip such that from a first extreme position, in which they are adapted to a cruise lip geometry, they can be moved into a second extreme position, in which they radially expand the outer contour of the intake lip while providing and exposing air blowoff ducts with their rear side, said ducts terminating at the outer wall of the nacelle at essentially a tangent therewith. Further air injection flaps are also provided in certain embodiments for forming air injection ducts through the intake lip walls during certain engine operating conditions.

    摘要: A two-dimensional, unidirectional oblique air impact diffuser is used as an air inlet for a gas turbine jet engine for aircraft. The air inlet includes an upper rigid air inlet ramp and an air inlet bottom spaced below the ramp. An air scoop lip is pivotally attached to the air inlet bottom so that it can be pivoted from a standard setting point downwardly away from the air inlet ramp and also from the standard setting point toward the ramp. The pivotal displacement of the air scoop lip is a function of the aircraft angle of attack and the flight Mach number. The angular displacement of the air scoop lip from the standard setting point increases downwardly as the aircraft angle of attack increases and decreases as the Mach number increases.

    摘要: A variable geometry inlet system is provided for a subsonic/supersonic gas turbine engine wherein a secondary inlet airflow is selectively ejected into a primary inlet airflow in order to augment the overall mass airflow to the engine and increase inlet pressure recovery. A plurality of foils are cooperatively disposed in rotatable connection with respect to a nacelle in order to modulate the secondary inlet airflow and match the velocity of the secondary airstream to that of the primary airstream thus reducing the mixing loss which would otherwise occur if the two streams commingled at different velocities. The primary and secondary inlet airstreams may also be maintained at a sufficiently high velocity to reduce the forward propagation of engine generated noise. The foils may also be rotated to define an outlet whereby a portion of the primary inlet airflow may be ejected overboard during supersonic operation to reduce aerodynamic drag as might otherwise result from a malfunctioning engine.

    摘要: A series of inlet fences or spoilers carried on the nacelle of an aircraft turbine engine which are used to selectively divert streamlines which would otherwise become detached at the inlet lip. This selectively variable air-inlet geometry provides for minimum drag during cruise and yet obviates engine surge or stall or other effects detrimental to the engine which could otherwise occur on the ground and at low forward velocity when crosswinds combine with high engine power demands.

    摘要: A jet engine, which is suited for hypersonic intake velocities, has a rotating cascade in the intake duct for decelerating the hypersonic flow. The blade angles Beta 1, Beta 2 of the rotating cascade, the circumferential speed U of the rotor and the deceleration Delta w of the relative cascade flow are matched in accordance with cos Beta 2 (U . cos Beta 1)/(U Delta W . cos Beta 1), to ensure an axial direction of the absolute flow at the rotor cascade exit. A stationary vane cascade can be arranged downstream of the rotor cascade, in the case of high blade camber, for further deceleration and axial straightening of the flow. The intake rotor can be coupled to an engine accessory power unit or to a compressor arranged downstream of the intake. Controllable flaps can be provided to route the gas jet leaving the engine combustion chamber either to a turbine arranged downstream for driving the compressor or directly to the engine outlet nozzle. The intake rotor can also be coupled to an acceleration cascade arranged downstream of the combustion chamber; the acceleration cascade can also be preceded by a stationary vane cascade.
