Abstract
A cooled vane or blade for a gas turbine engine has a cooling arrangement for its trailing region which can be accommodated in the relatively thin section available. In this arrangement the trailing region of the hollow interior of the blade is divided off from the remainder by a partition which may be apertured to allow cooling air to enter the compartment thus formed. The concave, pressure flank of the compartment is cooled by arrays of film cooling holes while the convex, suction flank has a perforated plate spaced therefrom to provide impingement cooling. The suction flank is therefore unapertured and there is no disturbance of the high speed airflow in this region. The spent impingement air leaves the aerofoil via a slot and may pass over pedestals en route to cool the entire trailing edge.
