Abstract:

Grid fin translation mechanism is the key actuator of trajectory and attitude control in reentry flight of the reusable launch vehicle. The kinetic characteristic of translation mechanism is investigated experimentally. An experimental device and experimental schemes comprise position test, transient state test and frequency test are set up. The linear displacement of servo piston rod and the angle displacement of rudder shaft are measured by the displacement sensors. Firstly, the cause of linear displacement abrupt change in position test and angle displacement vibration in transient state test is studied. Furthermore, small shaft turning angle frequency test in low, mid and high frequency are tested and the angle displacement signal delay are comparativly analyzed. The clearances in kinematic pairs are considered as the important affecting factor of kinetic characteristic of translation mechanism and its influencing mechanism is preliminarily proposed. The results provide research object and experimental fundament for farther dynamic analysis and optimal design of transmission mechanism.

Key words: reusable launch vehicle, grid fin, transmission mechanism, clearance influence
