The invention relates to an improvement to an installation for preventing the ingress of super-cooled water, ice, snow and other debris as taught in U.S. Pat. No. 3,329,377. In the patent, an inertial separator effect is used to prevent ingress of super cooled water, ice, snow and other debris to an aircraft engine. The effect is obtained by an installation including a duct formed in a sub-nacelle of the engine to extend generally longitudinally of the engine. An air deflecting surface in the duct confines the incoming air to a passage of reduced cross s...


For an aircraft engine comprising an encasing nacelle and provided with an air intake and an installation for reducing ingress of super-cooled water, ice, snow and other debris to said air intake, said installation comprising a duct extending generally longitudinally of said engine, an open inlet at the forward end of said duct and an outlet, spaced from said inlet in the downstream direction of said duct, one of the walls of said duct being co-incident with a portion of said nacelle, an air deflecting surface in said duct extending rearwardly from said ...
