DEVICE FOR RETAINING AND RELEASING APPENDAGES

An active tie rod for retaining and releasing appendages without shock is provided. The device comprises: a fixed base, a tie rod extending along an axis between two ends, a mechanism fastened to the base and temporarily retaining a first end of the tie rod, operating the mechanism to release the tie rod from the base, an end piece fastened to a second end of the tie rod, at least one appendage temporarily retained between the base and the end piece, a component disposed between the mechanism and the end piece, and an actuator of the component to modify a characteristic dimension of the component along the axis between two values, the component producing a tension in the tie rod for the first of the two values and the tension in the tie rod being reduced for a second of the two values.
