    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.

    Abstract: This patent relates to and describes a jet engine having a forward intake end, a rear exhaust end, and gas jets for forming a fluid barrier in proximity to the lower leading portion of the forward intake end, said fluid barrier moving forwardly of the intake end and generally below and parallel to the direction of the flow of air into the intake end to prevent the ingestion of particulate matter into the engine.

    Abstract: The gas filter assembly comprises a casing which has an inlet port means for receiving gas to be filtered and an outlet port means for passing filtered gas to a place of storage or use. A filter means is disposed within the casing between the inlet port means and outlet port means to disentrain solid particles entrained in the gas stream. A portion of the walls comprising the casing are pivotally connected to their fixed or associated wall portions. All of the pivot axes are located close to a common plane so that the pivotal wall portions can be rotated to a folded or collapsed position to reduce its overall size and facilitate transportation of the assembly and then unfolded or extended to its full size position for ''''field'''' or on-site erection of the assembly.

    Abstract: An air inlet for an aircraft propulsion system nacelle includes an outer skin, an inner skin, a lip skin, and a forward bulkhead. The lip skin extends between and to an outer end and an inner end. The outer end is disposed at the outer skin. The inner end is disposed at the inner skin. The forward bulkhead includes a first bulkhead portion and a second bulkhead portion. The first bulkhead portion and the second bulkhead portion are mounted to the outer skin. The first bulkhead portion and the second bulkhead portion are mounted to the inner skin. The first bulkhead portion includes a rigid body material and the second bulkhead portion includes a flexible body material.
