Abstract : The patent relates to a structural lock for locking in each of three axes, during the launch phase, the rotatable structural portion of a spacecraft and a despun structural shelf commonly used in dual spin spacecraft. A single sliding pin which connects the two sections, is withdrawn by a pyrotechnic device prior to achieving orbit. The pin engages an adjustable spring biased, two piece member which includes serrated mating surfaces for producing a positive shear path in the Z direction.
