AIRCRAFT FUSELAGE STRUCTURE COMPRISING AN ENERGY ABSORBING DEVICE |
摘要 |
An aircraft fuselage structure, includes a circumferential reinforcing frame (2) and a plurality of stringers (3) substantially perpendicular to the frame. The frame includes a mechanically weakened area able to cause its localized buckling under the effect of a compressive force exerted circumferentially thereon. The structure includes an energy absorbing device (5) having two effector members (52) secured to the frame respectively on either side of the weakened area, and a central core (51) maintained between the effector members such that a reduction in the distance between the effector members produces a deformation of the central core, which is able to absorb energy under the effect of the deformation.
