概要

It was concluded in the previous report that the body divergence phenomenon experienced during the flight test of a small test rocket was induced by the degradation of bending stiffness at the joint of a solid rocket motor chamber made from FRP and aluminum alloy vehicle structure. The cause for degradation was examined by testings and the results of the testings were analysed by introducing the effectivity factor of bending stiffness. It was found that the bearing type joint did not work as expected due to yielding of the FRP moter case. A friction type joint was introduced by providing slits at the joint and employing bolts with HI-TORQUE recess. Flight test results with the revised design have been successful.
