Abstract: An exhaust assembly for a jet powerplant of a supersonic airplane comprising a rear structure fitted with a thrust reverser. The rear structure includes a primary multi-flap nozzle of variable cross-section situated downstream of a primary duct, a secondary multi-flap nozzle of variable cross-section situated downstream of a secondary duct enclosing the primary duct and a fairing enclosing the secondary duct and fitted with a throat downstream of an exhaust orifice of the secondary nozzle, the throat being followed by a diverging portion. The thrust reverser comprises two eyelids affixed in a pivotable manner to the fairing, one on each side to of an axial plane of symmetry. The eyelids are movable between an active, thrust-reversal position wherein the eyelids project transversely into a gas jet downstream of the fairing to deflect the gas jet in a forward direction for thrust-reversal and an inactive, forward-thrust position wherein the eyelids are situated in an extension of the fairing.

Abstract: In order to rotationally drive a gear material (3) when the gear material (3) is gear machined using a hob (not shown), a drive hole (34) having a circular configuration in section and extending on an axis L of the gear material (3) is formed in an end face (3e) of the gear material (3) and a shaft member (4) having a polygonal configuration is employed. The distance from an axis of this shaft body (4) to each angular portion (4a) is larger than the radius of the drive hole (34). The distance from the axis of the shaft member (4) to each side portion (4b) of the shaft member (4) is smaller than the radius of the drive hole (34). The shaft member (4) is fitted, under pressure, in the drive hole (34) and the gear member (3) is rotationally driven through this shaft member (4).

Abstract: A rear mixer ejector of a turbomachine for a supersonic aircraft has an ejector casing of rectangular cross-section fitted with movable flaps defining a variable geometry exhaust nozzle, and cold air mixing devices mounted on the casing side walls upstream of the nozzle. The mixing devices comprise a plurality of U-section chutes extending into the casing from apertures in the casing side walls, each chute being formed by a pair of lateral walls and a transverse wall disposed between them. The chutes are adjustable between a deployed position and an inoperative position, either by pivoting the chutes about axes at the downstream edges of the apertures or by pivoting only the transverse walls about the upstream edges of the apertures. In each case the lateral walls of the chutes remain in the gas flow path through the casing, parallel to the casing axis, in both the deployed and the inoperative positions, and the transverse walls are parallel to the casing axis in the inoperative position.

Abstract: A transformer, comprising: a closed ferrite magnetic circuit having an air gap; a rigid component filling a portion of the air gap; and, a flexible material filling the remainder of the air gap to substantially absorb vibrations of the ferrite.
