Abstract

A study on gust load alleviation using aircraft control surface was performed. Aeroservoelastic model including control surface controller was formulated and validated by comparing the results of continuous gust response analysis with those of MSC/NASTRAN. Optimal control with output feedback was adopted for designing the control surface controller, and the effects of gust load alleviation was validated by performing the numerical simulation for the controller designed.

항공기 조종면을 이용한 돌풍하중 완화기술에 대한 연구를 수행하였다 조종면 제어기를 포함하는 서보 공탄성 모델을 구성하였으며, 이에 대한 연속돌풍 응답해석을 수행하여 MSC/NASTRAN을 이용한 해석결과와 비교하여 시보 공탄성 모델을 검증하였다. 조종면 제어기 설계에는 출력 피드백을 이용한 최적 제어기법을 사용하였으며, 설계된 제어기에 대한 수치 시뮬레이션을 수행하여 돌풍하중 완화효과를 검증하였다.
