The present invention relates to a process for fitting a connecting member at one end of a control rod, wherein a sleeve of resistant fibres impregnated with polymerizable resin is applied substantially against the inner wall of the end, the end is flattened at least until the portions of inner face of the sleeve, disposed on either side of the plane of flattening, are applied against one another, substantially completely obturating the section of the flattened portion of the tubular end, and the resin impregnating the sleeve is polymerized after flattening. The invention is more particularly applicable to the obtaining of light, resistant connecting rods, especially for aircraft.

Control rod and a process for fitting a connecting member at one end of

A variable-pitch, multi-blade propeller specially usable as a rear rotor of a rotary-wing aircraft and a process for manufacturing the same are described. The propeller comprises a number of pairs of blades emanating from a central hub, each pair comprising a single elongate strip secured at its center to the hub. The strip is composed of two flat bundles of fibres and defining an aperture for a sliding shaft at their center. The shaft is used to control the pitch angles of the blades and aerodynamic blade shells are secured to the fibre bundles by adhesive synthetic cellular or foam material.
