| 摘要 | A protection device (20) for protecting a fuselage (2) of a rotorcraft (1) against a pyramid-shaped structure (10) for carrying a load, which pyramid-shape structure has a frame having a quadrilateral shape together with a first pair (13) of two arms (12) and a second pair (15) of two arms (14), each arm extending in elevation from the frame up towards an apex (16). The protection device includes a protective plate (21), a blade (30) secured to the protective plate (21) for exerting a force on the two arms of the first pair, and a chevron (40) provided with two branches connected to the protective plate (21) in order to tend to move the arms of the second pair transversely apart from each other. | ||

| 主权项 | 1. A protection device for protecting a fuselage of a rotorcraft against a pyramid-shaped structure for carrying a load, the pyramid-shaped structure being provided with a frame having a quadrilateral shape, a first pair of two arms, and a second pair of two arms, each arm extending in elevation upwards from the frame towards an apex, wherein the protection device includes: a protective plate suitable for being interposed between the fuselage and the pyramid-shaped structure; a blade secured to the protective plate for exerting a force on the arms of the first pair in order to break them; and a chevron provided with two branches connected to the protective plate in order to tend to move the arms of the second pair transversely apart from each other. | ||
