Lock mechanism at launch applied to a small rocket microgravity experimental device

摘要

PURPOSE:To operate a launch-lock system for a long period and perform smooth unlocking and sure relocking by mechanically coupling or releasing a support base plate supporting a micro-gravity experimental device to an airframe side. CONSTITUTION:An experimental device 100 is fitted via a main base plate 6, a lock system 5 and a support base plate 4 on a rocket side. When switches 24, 25 are turned on at the time of launch-lock, electromagnetic wedges 101a, 101b are operated, and fitting shafts 19, 26 are fixed at both ends of a sliding groove 36. When the switch 24 is turned off by remote control from the ground at the time of unlocking, the electromagnetic wedge 101a is made nonoperational, and a support lever 9 is separated from an experimental device support metal 11 by the force of a spring 17. When the switch 25 is turned off at the time of re-locking, the other electromagnetic wedge 101b is made nonoperational, and the support lever 9 is hooked by the experimental device support metal 11 via the force of a spring 14. The switch 24 is turned on from the ground, the electromagnetic wedge 101a is operated, and a fitting shaft 26 integral with a sensitive piece is fixed.
