小型・高速応答加速度センサーシステムの開発

Abstract

The aim of the study is to develop a small system and high response acceleration system for forces measurement of rocket, cornering force and impulse of crash car and hypervelocity testing for space vehicle. The acceleration system is mounted on the front nose of pet rocket and accelerated to a speed up to 4G for the experiment. During the experiment, which will last approximately one minute, acceleration data for the rocket is recorded. Results show that rocket axial acceleration increases as axial force increases. The hypervelocity testing for space vehicle will be planed a wind tunnel experiment of ground tests performed in the HIEST high-enthalpy shock tunnel facility.
