THE STUDY ON FLEXIBLE CARBON FIBER BOOM FOR SOUNDING ROCKET

摘要

To accommodate the requirements of the sounding rocket that will be launched soon, this paper develops a new boom, which makes six new contributions: its deployment doesn't need proper centrifugal force generated by rocket anymore, suitable for the requirement that the sounding rocket is controlled not to rotate when rising; it is made by the flexible carbon fiber material and thus has a light weight; its deployment is driven by the bending elastic potential energy, more reliable and safer; due to its light weight, the effects on the rocket posture of its deployment are minor; its locking is done by itself but not by the rocket, which effectively avoids the interference of the separation of the rocket arrow and body with its deployment and enhances the reliability of its deployment; its unlocking is done by a fuse, more economic and more reliable.
