Abstract: An aircraft engine guard, for protecting an aircraft engine against ingestion of large objects, includes a generally cone-shaped body, a base section of the rear end of the guard body and a dome section at the distal forward end of the guard body, at least three, vertical, peripherally extending walls located between the base and the dome section, with successive ones of the peripheral walls having different peripheral dimensions, peripherally cylindrical, with the dimension increasing from the base toward the dome section. A plurality of air intake openings are defined in and between the peripheral walls with at least one dimensional size which is small enough to prevent having birds from being able to pass through the guard into the aircraft engine.

Abstract: Embodiments include an inlet particle separator system for a gas turbine engine. The inlet particle separator system includes an inertial particle separator that separates incoming air into a cleaned air flow and a scavenge flow. Embodiments may also include an ejector that provides a draw on a scavenge duct and entrains the scavenge flow into a charged flow, e.g., such as the output of a first stage fan. The ejector may have a variable output.

Abstract: An inlet particle separator system for a vehicle engine includes a hub section, a shroud section, a splitter, and a hub suction flow passage. The shroud section surrounds at least a portion of the hub section and is spaced apart therefrom to define a main flow passageway that has an air inlet. The splitter is disposed downstream of the air inlet and extends into the passageway to divide the main flow passageway into a scavenge flow path and an engine flow path. The hub suction flow passage has a hub suction inlet port and a hub suction outlet port. The hub suction inlet port extends through the hub section and is in fluid communication with the air inlet. The hub suction outlet port extends through the splitter and is in fluid communication with the scavenge flow path.
