Abstract

A cooling apparatus for cooling a fluid in a bypass gas turbine engine comprises a heat exchanger disposed within a bypass duct and accommodated by a sub-passage defined by a flow divider affixed to an annular wall of the bypass duct. The sub-passage defines an open upstream end and an open downstream end to direct a portion of the bypass air flow to pass therethrough. A sealing assembly for the bypass duct is also provided.

Claims

1. A seal assembly for a gas turbine engine bypass duct cooler, said assembly comprising:

a bypass duct cooler having a peripheral recess;

a body having an opening, said opening bounded by a peripheral flange arranged angularly to a surface of said body, said recess and flange being configured such that said flange is receivable within said recess; and

a seal disposed within said recess substantially continuously around the periphery, said seal adapted to sealingly engage said flange when said recess is mated with said flange.

2. The assembly as defined in claim 1, wherein said cover means includes a peripheral groove for receiving said secondary seal.

3. The assembly as defined in claim 1, wherein said seal includes a groove having a V-shaped profile.
