Abstract
A turbomachine of the «open rotor» 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.
Claims15
A turbomachine for an aircraft, said turbomachine comprising at least one unenclosed propeller and a nacelle defining an air inlet, a central hub positioned downstream of the air inlet and an air intake section surrounding the central hub and opening into an air supply main section, with the central hub comprising a central trap having an aperture for trapping foreign objects contained in an air flow entering the turbomachine, and the air intake section being totally annular about the aperture of the central trap, with the central trap comprising an air recovery channel configured as an annular air recovery channel, with said air recovery channel including a filter for filtering the foreign objects in recovered air, characterized in that one discharge end of said air recovery channel, through which said air recovery channel opens into the air supply main section, is provided on the central hub.
