JAXA has been conducting research and development of the on-board safety avionics technology to prevent turbulence-induced aircraft accidents (Safe Avio) that uses Doppler light detection and ranging (LIDAR) to detect the turbulence in advance and the preview controller to utilize the turbulent velocity information measured by LIDAR to attenuate the aircraft acceleration in turbulence. The preview controller should be validated by a subsonic GA (Gust Alleviation) wind tunnel testing as the first step. The high performance actuator system, which drives the control surfaces to alleviate the gust influence on the aircraft, is required to realize the wind tunnel testing. A design study, prototyping and performance evaluation of the piezoelectric actuator system installed in a model wing for the subsonic GA wind tunnel testing are carried out. The results
show that the actuator system demonstrates the sufficient dynamic and endurance performances to satisfy the requirements including the +/-10deg wide range of the output deflection.
