A hollow cooled vane for a gas turbine engine comprises at least two apertured members each mounted spaced from a separate part of the vane interior surface. The first of these members is provided with a supply of cooling air which passes through the apertures in the form of jets to impingement cool the respective first surface, and an interconnecting passage is provided to take this air to the second apertured member where it impingement cools the respective second surface. |
