Abstract: A directional and stabilizing device is provided including a faired antitorque rotor, driven in rotation in a transverse aperture formed in a fairing slanted with respect to the vertical by an angle between 0 DEG and 45 DEG . It also includes a "V" empennage fixed to the top of the fairing and the two aerodynamic surfaces of which extend disymmetrically with respect to the vertical plane passing through the top of this fairing, the aerodynamic surfaces being slanted in angular planes between 0 DEG and 45 DEG .

Abstract: In a main transmission gearbox for a helicopter having two engines, a lifting rotor and an anti-torque rotor, each of the two engines drives a main kinematic chain comprising from upstream down, an input shaft, a twistable shaft, a gear train forming a first reduction stage having a first bevel pinion meshing with a second bevel pinion which drives in rotation a vertical shaft bearing having a third pinion in mesh with a gearwheel which is common to the two main chains and forms with the third pinions a second reduction stage. The torque received at the gearwheel is transmitted to the driving shaft of the main rotor by way of a supplementary reduction stage of epicyclic type. A third chain comprising two input pinions each of which is mounted upon one of the input shafts and an intermediate pinion which drives the driving shaft of the anti-torque rotor, ensures the distribution of power over the two main chains in the event of breakdown of one engine.

Abstract: A variable pitch multi-blade propeller suitable for use on a helicopter is constructed of a foam preform joined with a fibrous spar enclosed in resin-impregnated foils and fitted with a metal leading edge. Various components are assembled in a mold and the resins, then cured. The structure may further include a reinforcing yoke of carbon fiber fabrics preimpregnated with a polymerizable synthetic resin. The process may further include a heat treating step to effect polymerization.

Abstract: The subject of the invention is a suspension device for a helicopter, intended for reducing the vibrations caused by its rotor. The main transmission box of the rotor is supported at the top by a set of oblique articulated bars and is bolted at its bottom to a diaphragm made of thin sheet metal, which can be deformed by bending, but not by shearing in its plane. Flexible arms arranged radially and supported by fixed mountings are articulated to the foot of the oblique bars and to the bottom of the transmission box; they each carry, at the end of a lever, a swinging weight acting by the effect of inertia.

Abstract: The multi-directional suspension for helicopters takes up the turning momentum of the transmission to the rotor blades as well as to static and dynamic forces at right angles to the axis. IT has a base plate (17) carrying the drive structure, which transmits the static forces and simultaneously damps the oscillations relative to the structure by taking up the reaction momentum of the main rotor through the suspension of the rotor drive with the drive supported on the fuselage by several inclined stays acting together. The multi-directional suspension includes a flange (17) rigidly connected to the transmission (12) which lies mainly in a plane extending at right angles to the axis (13). In addition, there is a complex of connecting elements rigid against turning between the flange and the construction or fuselage to take up the turning momentum.

Abstract: The invention relates to a variable-pitch rotor, specially for a rotary-wing aircraft. Each blade of the rotor is connected to the hub by a flexible connecting member comprising a radial bundle of fibres, each agglomerated by a resin and secured together by a vulcanized elastomer. A rigid tubular sleeve surrounds the connecting member without contact thereto. The outer end of the tubular sleeve is secured to the root part of the blade and its inner end is secured to a rigid ring, to which a blade pitch control lever is externally articulated. Spherical ball and socket joint members are inserted between the rigid ring and rigid parts of the rotor hub. Frequency adaptors are associated with the ball and socket joint members.
