ABSTRACT:
A duct wall embracing the turbine of a gas turbine engine is cooled by impingement of air jets on to the outside of the wall. For control of the air flow the wall is surrounded by a chamber divided into inlet and outlet regions by a partition having spaced apart portions projecting towards the wall. The air jets emerge from nozzle openings in the free ends of the projections. Air rebounding from the wall enters the spaces between the projections and so does not interfere with the flow of fresh air thereby raising the efficiency of the heat exchange.
