A turbomachine of the &#xab;open rotor&#xbb; type or a turboprop engine comprises a nacelle defining an air inlet, a central hub and an annular air intake section surrounding the central hub and opening into a air supply main section, with the central hub comprising a central trap having an aperture for trapping the foreign objects in an air flow entering the turbomachine, and an air recovery channel having a discharge end, through which said air recovery channel opens into the main section, is provided on the central hub.

Turbomachine comprising a trap for foreign objects circulating in an air flow

Air inlet duct of a turbine engine, in particular an aircraft turbine engine comprising a gas generator, which extends axially between the air inlet and the gas generator and has a first axial wall part and a second wall part which is angularly offset with respect to the first part, which duct is capable of causing, in a shedding region, shedding of the boundary layer formed by an air flow along the wall of the duct; and a device for controlling said shedding of the boundary layer, characterised in that the control device comprises an air-blowing pipe which opens via at least one air-injection opening which is directly upstream of the shedding region, the blowing pipe being connected to an air intake positioned upstream of said air-injection opening or in the shedding region and comprising an air compressor means between the air intake and the air-injection opening.

Air inlet duct for an aircraft turbine engine

Air intake duct for supplying air to a turbine engine gas generator, in particular an aircraft turbine engine, extending axially between the air intake and the gas generator and having a deflection which may cause shedding of the boundary layer formed by the air flow along the wall of the duct, wherein said air intake duct comprises a guiding element located in the duct and designed to guide the air along the wall of the duct to a portion having the deflection, said guiding element extending transversely to the direction of the flow of air and having at the ends thereof two end profiles that form a non-zero angle with the guiding element, said two end profiles being able to produce eddies in the air flow.
