Abstract: A bushing for positioning between a first component and a second component is disclosed. The bushing comprises a conical body that includes a first edge, a second edge, and at least one slot extending from the first edge toward the second edge. The slot or slots facilitate the flexing of the conical body. Methods for making a conical bushing are also disclosed.

Abstract: A compressor bleed air passageway includes a duct having an upstream section (48) which terminates in a baffle (44) and a downstream duct section (54) having a forward portion (56) which surrounds the baffle (44). Bleed air flow through openings (58) in the baffle wall (52). This reduces velocity of the bleed air stream at the duct discharge port to a value equal to or less than Mach 1.0. The baffle (44) has virtually no effect on a low-velocity, low-pressure air stream. The downstream duct section (54) may be perforated and surrounded by outer wall (64) to form sound-absorbing chambers (66).

Abstract: A method of enhancing Coanda flow attachment over a wing and flap surface of an upper surface blowing aircraft comprising the step of directing the jet exhaust flow or stream toward regions wherein the exhaust flow separates from the wing and flap surface so as to create an outward velocity component which prevents ambient air from flowing in and under the exhaust from the sides of the exhaust flow and causing such separation is disclosed. The method comprises the further step of creating vortices also having outward velocity components on the wing and flap surface. The outward velocity components of the vortices further increases the sidewise velocity component on the wing surface. In addition, the rotational velocity components of the vortices scrub the boundary layer air from the flap surface to further promote flow attachment.
