Abstract: A cooling system for use in an engine having an element to be cooled includes at least one cooling channel on a first side of the element, at least one cooling channel on a second side of the element, and the at least one cooling channel on the first side communicating with the at least one channel on the second side in a nose region of the element so as to form a cooling circuit. The cooling system has particular utility in cooling interior and exterior surfaces of a movable cowl inlet flap used in a scramjet engine.

Abstract: A seal assembly for use in an engine, such as a scramjet engine, having a movable element, such as inlet cowl flap, is provided. The movable element has an outboard structural member which requires thermal protection. The seal assembly includes a sealing element and a support block for thermally isolating the outboard structural member and for supporting the sealing element. In a preferred embodiment, the sealing element comprises a rope seal having a tadpole construction.
