摘要： A rotor disc blade (10) for a turbomachine made from composite material comprising a fibrous reinforcement obtained by multilayer weaving of yarns and densified by a matrix. The blade (10) comprises a portion that forms the airfoil (12) and the blade root (14) forming a single part, the blade root (14) having two substantially planar opposing side flanks (22, 24) that are formed in the respective extensions of the pressure (12a) and suction (12b) surfaces of the airfoil (10). The blade root (14) is gripped between two metal plates (26, 28) fixed against the side flanks (22, 24) of the blade root by a screw (30) and a nut (40) passing through the plates (26, 28) and the blade root (14). The screw (30) comprises a head (31) bearing on one (26) of the two plates. The nut (40) comprises a head (41) bearing on the other plate (28). The screw and the nut (30, 40) apply, to the metal plates (26, 28), a minimum clamping force capable of taking up, by friction between the metal plates (26, 28) and the side flanks (22, 24) of the blade root (14), a predefined centrifugal force applied to the blade (10).

摘要： Turbomachine blade (10) made of composite comprising a fibre reinforcement obtained by the three-dimensional weaving of filaments and densified by a matrix, the blade comprising a first part constituting the aerofoil (20) and blade root (30), the blade aerofoil (20) having two faces (22, 23) each connecting a leading edge (20a) to a trailing edge (20b). The first part forms a single piece with at least one second part present only on one of the faces of the blade aerofoil, said second part being the constituent element of part of at least one of the following elements: the blade platform (40), the tang (50) that prevents the blade from rocking, the blade shroud spoilers (60) and blade shroud wipers (70), the fibrous reinforcing parts corresponding to the first and the second parts of the blade being at least partially imbricated in one another, with filaments of the first part of the fibrous reinforcement penetrating the second part of fibrous reinforcement.

摘要： The invention relates to a method for optimising the profile of a blade made from a composite material for a movable wheel of a turbomachine. The method comprises the following steps: a blade aerofoil compensation step consisting in dividing (E110) the aerofoil into segments and, for each aerofoil segment and a pre-determined rotation speed of the disk of the wheel, calculating (E120) the centrifugal force to which the segment is subjected, calculating (E130) the moment of the aerodynamic force being exerted on the lower section of the segment and calculating (E140) the values of the movements to be applied to a centre of gravity of the segment in order to cancel the moment of the aerodynamic force; and a step comprising the compensation of the extended root of the blade, consisting in calculating the centrifugal force to which a portion of the blade, located above the neck of the aerofoil, is subjected, calculating (E210) the moment of the aerodynamic force being exerted on a lower section of the extended root of the blade and calculating (E220) the values of the movements to be applied to a centre of gravity of the extended root of the blade in order to cancel the moment of the aerodynamic force. The invention also relates to a blade including an extended root thus compensated.
