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 substantiall...


A gas turbine engine cowling suitable for a helicopter comprising a casing, a gas turbine engine enclosed within said casing, primary duct means adapted for the passage of air through said cowling, secondary duct means interconnecting said primary duct means and the air intake of said engine, a vortex tube separator panel interposed between said primary duct means and the intake of said engine and located at the junction of said primary and secondary duct means so as to constitute a portion of the wall of said primary duct means, and air flow inducing me...
