<p>An energy absorber and deflection device for deflecting engine debris (7) fragments from their tangential trajectory from a core of a gas turbine engine. The device includes a deflection plate (8) radially spaced from a protected portion of the periphery of the rotor, adapted to cover the protected portion in a closed position, and to swing open about a fore edge of the deflection plate to a deployed position. A flexible joint secures the fore edge (10) of the deflection plate (8) to the engine and a frangible joint secures an aft edge (11) of the deflection plate to the engine. In the case of a turbofan engine, the deflector plate may form part of the inner bypass duct surface to deflect debris (7) to exit aft through the bypass duct (2), and in turboshaft and turboprop engines the deflector plate (8) serves to deflect debris (7) and reduce debris (7) velocity to contain debris (7) within the engine cowling or nacelle.</p> |
