摘要： A rotorcraft rotor with hinged blades, includes: a hub; a plurality of blades hinged to flap relative to the hub; bottom abutments of the hub, and bottom abutments of the blades suitable for co-operating with the bottom abutments of the hub; and top abutments of the hub, and top abutments of the blades suitable for co-operating with the top abutments of the hub; the top abutments of the hub being movable between a deployed position in which they extend facing the top abutments of the blades, and a retracted position in which they are offset angularly away from the top abutments of the blades. The rotor also includes elements for locking the top abutments of the hub in the deployed position, and inertial means for releasing the top abutments of the hub and for deactivating the locking means.

摘要： The tightening clamps are multifunctional and ensure the transmission of the electric current generated by the fuel cell stack, the insulation of the different ducts and passage openings of the operation fluid of the fuel cell stack, and the tightening of the stack itself.Each clamp comprises a single part, the upper surface and the side surfaces of which, except for the conductors, are coated with an insulating material. Similarly, the supply and discharge openings (23) are also insulated. However, the tightening surface (29) is at least coated with a conductive deposit on a predetermined area corresponding to the conducting areas of the upper surface of the end of the stack.The invention can be used in PEM (“Proton Exchange Membrane”) fuel cells.

摘要： A gearbox with a transmission input shaft and an output shaft mounted parallel in a gearbox housing and includes several pairs of engaged pinions to shift in a corresponding number of forward transmission ratios. A reverse gear axle is mounted in the housing parallel to the input and output shafts, with two idler gears freely rotatable on the shaft, one gear engaging a fixed gear on the input shaft, the other engaging a fixed gear on the output shaft. A reverse synchronizing device is located between the two idler gears for engaging reverse gear ratio. The synchronizer includes a jaw clutching sleeve splined to one of the idler gears, and is slidable towards the other idler gear to actuate a synchronizing clutch. The clutch has radially inward facing champfered blockers which engage corresponding slots in the sleeve. A synchonization initiation device in the form of a snap ring is also provided.
