Summary: | A rotary-wing aircraft includes a fuselage (2), and an external device (10). The fuselage (2) is provided with a rotary wing (4). The external device (10) is mounted on the outside of the fuselage (2). The external device (10) includes a mounting device (12), a mass variation device (14), and a damper (16). The mounting device (12) is fixed to the fuselage (2) and disposed so as to project in a lateral direction of the fuselage (2). The mass variation device (14) is mounted on the mounting device (12) and has a mass that varies as the mass variation device (14) is used. The damper (16) couples the fuselage (2) to the mounting device (12) and supports the mounting device (12). The damper (16) includes a stiffness variable mechanism (20) configured to change stiffness of the damper (16) in response to variation in the mass of the mass variation device (14). |
