ABSTRACT:
A gas turbine engine cowling suitable for a helicopter contains a gas turbine engine having a vortex tube separator panel for the purpose of separating water droplets and particulate material from engine inlet air. The vortex tube separator panel is mounted in a duct extending the length of the cowling so that air passing through the duct supplies air for passing through the panel to the engine inlet as well as maintaining a flow of air transverse to the panel. The air flow transverse to the panel ensures that blockage of the panel by ice is substantially reduced or eliminated. Under forward flight conditions, ram air passes through the duct but during hovering, the air flow through the duct is induced by an ejector powered by the exhaust efflux from the engine. The portion of the air flow through the duct which does not enter the gas turbine engine is utilized in the cooling of the engine exhaust efflux in order to reduce the amount of infra-red radiation emitted thereby.
