Abstract
An air intake guide for a jet propulsion power plant for a supersonic aircraft comprises an intake aperture, an intake center body and an intake adjustment device. The intake aperture has an intake lip, an intake center body is positioned within the aperture, and an intake adjustment device is positioned on a radially inwardly facing surface of the air intake guide downstream of the intake lip. The intake adjustment device comprises a flexible panel and an actuator with the actuator being adapted to deflect the flexible panel in a radially inwardly direction so as to reduce a cross-sectional area of the intake aperture and thereby to position a shock wave at the intake lip.
Claims11
An air intake guide for a jet propulsion power plant for a supersonic aircraft, the air intake guide comprising:
- an intake aperture having an intake lip;
- and
- an intake adjustment device positioned on a radially inwardly facing surface of the air intake guide downstream of the intake lip,
- wherein the intake adjustment device comprises a flexible panel and an actuator, the actuator being adapted to deflect the flexible panel in a radially inwardly direction so as to reduce a cross-sectional area of the intake aperture,
- wherein the air intake guide further comprises a flexible fairing positioned downstream of, and contiguous with, the flexible panel, and
- wherein the actuator comprises a first, high rate response actuator and a second, low rate response actuator.
