Abstract
An intake duct (1) for an aircraft jet propulsion engine (2) has a surface region (4) on which a bird travelling along the duct will impact before being ingested by the engine. To minimize damage to the engine, the surface region (4) is formed such that part of the bird is retarded relatively to the remainder, the resultant distortion effecting extravasation and evisceration which produces bird debris of a sufficiently low density to be safely ingested by the engine.
