Abstract: A helicopter presenting a passenger compartment defined longitudinally by two transverse walls and laterally by two swing-up doors; the passenger compartment being equipped for administering first aid and the conveyance of casualties, and presenting a support, adjacent to one of the transverse walls, for a first stretcher;a main seat adjacent to the other transverse wall; a support, incorporated in the main seat, for a second stretcher; and two standby seats retractable inside the support of the first stretcher.

Abstract: A helicopter rotor brake device includes a fixed casing. A shaft is supported in a rotationally free manner inside the casing and is rotatably connectable to the rotor. A pair of first friction disks connected to the casing. A hub is fitted integral with a second friction disk interposed axially between the first friction disks and cooperates in a sliding manner with the same when loaded axially. A clutch is interposed between the shaft and the hub and is movable between an idle position corresponding to a rotational disconnection of the hub and the shaft, and an operating position corresponding to a rotational connection of the hub and the shaft.
