Abstract
A device for the unlockable connection between two objects such as a satellite and a spacecraft incorporating a rotary key connection. The unlocking connection is made by the rotation of a ring carrying the key. This rotation is induced by the axial displacement of a rod carrying the ring and controlled by a spring. This spring is released by an initiating system, such as a pyrotechnic or similar system.
Claims10
An unlockable connection device to connect a first object and a second object, comprising:
- a tube member secured to the first object;
- a rod member having a longitudinal axis;
- an unlockable blocking means adapted to immobilize a first end of the rod member with respect to the second object;
- unlocking initiating means adapted to control unlocking of the blocking means;
- resilient means adapted to move the rod member in a direction along its longitudinal axis, away from the second object, upon unlocking of the blocking means;
- a rotary key system carried by a second end of the rod member and engaging an end wall of the tube member;
- and
- means for controlling a rotation of said key system about the longitudinal axis of the rod member, when the rod member moves in said direction, thereby to free the key system from said end wall whereby the attitude and velocity of the second object are controlled upon release from the first object.
