    • 专利摘要:
    A turbo-engine guard (2) for mounting on the air inlet (1) of a turbo-engine, comprises guard elements (3) possessing an aerodynamic design.Preferably the guard elements (3) are helically mounted, preferably along several helical lines.Appropriately the guard elements (3) are kept under a tension so that these elements return to their original position after collision.In a preferred embodiment in case of breaking of a guard element 3 in pieces, the resultant parts undergo an appropriate shortening, preferably obtained by a spring force introduced into these parts, to a length being less than the distance between the rotating parts of the engine and the location at which this resultant part is kept in position.The resultant parts can also be pulled away from the inflowing air stream by means of a member or construction mounted inside or outside the air inlet and/or inside or outside the element (3) concerned.

    Claims (4)
    [1]
    1. A device for protecting a turbojet engine from foreign objects, containing aerodynamic-shaped protective elements mounted in the air intake body with axial displacement relative to each other, characterized in that, in order to increase protection efficiency, protective elements are installed along a number of helicoidal lines.
    [2]
    2. The device according to claim 1, wherein the protective elements are fully or partially made of fibrous, film-like or wire-like elements, which are made turned 5 with respect to their longitudinal axis.
    [3]
    3. Y '. - Property according to claims 1 and 2, characterized in that the protective elements are made. at least partially from plastic materials of the polyphenylene terephthalamide type, wherein the fibers and parts of carbon are bonded with a binder that is resistant to a temperature of (-50) to 150 ° C.
    4. The device according to paragraphs. 1-З.differs from the fact that the protective elements have a weakened part.
    5. The device according to claims 1 to 4, characterized in that it is equipped with a device for removing the residual part of the protective element
    10 ta with a length of the latter less than the radial clearance of the engine flow passage.
