A deployment and aiming device of an instrument comprises: a first support, a second support to receive the instrument, N mandrels, N being an integer number greater than or equal to 1, positioned around the first support, each of the N mandrels rotationally mobile relative to the first support about a mandrel axis ZN intersecting the mandrel, N linear elements, each of the N linear elements cooperating with one of the N mandrels, each of the N linear elements having first and second ends, wherein the first end of the N linear elements is fixed in the mandrel with which it cooperates at a fixing point, wherein the second end of the N linear elements is linked to the second support, such that a rotation of the mandrel about its axis ZN generates a displacement of the fixing point.

Deployment and aiming device

A deployable assembly comprises a supporting structure, a set of panels, each being linked to the adjacent panel by a hinge defining an intermediate axis of rotation, capable of switching from a stowed configuration in which the panels are folded one on top of the other to a deployed configuration, by rotation of the panels about the respective intermediate axes of rotation, wherein the panels are arranged substantially in the same plane, an articulation device defining a main axis of rotation of the set of panels relative to the supporting structure. The set of panels is rotationally mobile about the intermediate axes of rotation and the main axis of rotation to switch from the stowed configuration to the deployed configuration and the set of panels is only rotationally mobile about the main axis of rotation in deployed configuration to orient the set of panels relative to the supporting structure.

Deployable assembly

A solar generator deployment device includes at least one primary tape-spring supporting a flexible membrane with a set of flexible photovoltaic cells on one face, at least one secondary tape-spring, and a reinforcing structure attached to the primary tape-spring and secondary tape-spring, said device having a wound state in which the primary tape-spring supporting the flexible membrane and secondary tape-spring and reinforcing structure are co-wound around a mandrel; and an unwound state in which said primary tape-spring and secondary tape-spring are unwound. The device comprises, at the level of said mandrel, means for offsetting, in the unwound state, the root of said secondary tape-spring so that the reinforcing structure is deployed within a volume situated on the side opposite the face of the flexible membrane comprising flexible photovoltaic cells and supports said flexible membrane, the device then being in the deployed state.

Boxed unwindable solar generator

A nanometer-scale precision actuator comprises a base, an intermediate structure, an output interface, and two linear elements producing a controllable extension in the same longitudinal direction, each between a first and a second end. A first of the two elements has a first end fixed onto the intermediate structure and a second end fixed onto the base, a second of the two elements has a first end fixed onto the intermediate structure and a second end fixed to the output interface. The base and the intermediate structure are positioned in such a manner that the controllable extension of the second element produces a displacement of the actuator in a first direction and the controllable extension of the first element produces a displacement of the actuator in a second direction, opposite to the first direction, with respect to the base.

Precision return actuator

An autonomous spontaneous deployment deployable mast includes at least one elementary structural unit having a longitudinal deployment axis X and two platforms parallel to a plane YZ orthogonal to the axis X. The elementary structural unit includes N stages stacked above one another parallel to the longitudinal deployment axis X, where N is greater than 1. Each stage includes at least three longitudinal flexible tape-springs, the N stages being fixed to one another two by two by means of connecting platforms parallel to the plane YZ and two contiguous lower and upper stages being offset angularly relative to each other by rotation about the deployment axis X, the tape-springs of the lower stage being interleaved between the tape-springs of the upper stage.

A self-driven articulation designed for automatically deploying the elements that it connects including two articulation fittings made to rotate under the action of at least one passive drive element. The articulation includes at least one flexible duct for regulating the speed at which it deploys.
