Abstract

In a gas turbine engine 10 cooling air which has been utilised to cool accessories 20 is ducted to an exit which directs the air over the engine casing structure so as to re-energise boundary layer flow and/or reduce base drag. The exit may comprise apertures (38, 40) formed in the fillets at the junction between an engine casing and the casing of a pylon supporting the engine (figure 2), or slot-like outlets (64) formed at the trailing end of a support pylon casing (figure 3).
