摘要:
A convertiplane (1) having a wing (4) in turn having two half-wings (6), each defined by a fixed portion (13) adjacent to the fuselage (2), and by a movable portion (14) rotating, with respect to the fixed portion (13), about a beam element (7) extending the full length of the wing (4); the beam element (7) supports, integrally, rotors (11) located at respective ends of the wing (4), and engines (20) connected to the rotors (11) by a transmission (25), and is rotated about a respective axis (A) by actuators (48) to change the position of the rotors (11) from a vertical-axis position wherein the convertiplane (1) operates in helicopter mode, to a horizontal-axis position wherein the convertiplane (1) operates in airplane mode.

摘要:
A rotor (3) for a helicopter (1), having : a hub (5) rotating about an axis (A) and in turn having a number of blades (9); and an at least partly hollow drive shaft (6) connectable to a drive of the helicopter (1) and connected functionally to the hub (5) to rotate the hub (5) about the axis (A); the rotor (3) also having vibration damping means (15) in turn having a mass (17), and an elastically deformable member (16) connected to the mass (17) and supported by the shaft (6); the member (16) extending at least partly inside the shaft (6), and being elongated parallel to the axis (A); and the mass (17) vibrating, in use, at such a frequency as to oppose transmission to the shaft (6) of the vibration produced by rotation of the hub (5) and blades (9).

摘要:
An aircraft (1) capable of hovering, and having a fuselage (2) defining an access opening (12); operating means (30) for operating a rescue cradle (32); and a first door (16) movable between a closed position engaging a first portion (24) of the opening (12), and a first open position allowing access to the first portion (24) of the opening (12). The aircraft (1) has a member (39) connected functionally to the first door (16) and in turn having at least one flat surface (40); and the member (39) is movable with respect to the wall (16) into a first position, in which the flat surface (40) defines a supporting surface for the cradle (32) when the first door (16) is in the first open position.
