AbstractThis investigation determines the worst case gust response of a typical airfoil section with a control surface. Matched filter theory is employed in order to compute the gust that produces the maximum response. These results are compared with a tuned 1-minus-cosine gust, one of the standard representations of discrete gusts. It is found that the responses obtained by the matched filter theory are about twice as large as those obtained using the 1-minus-cosine gust and the matched filter theory can estimate closely. Moreover, it is found that the hinge stiffness of the control surface can affect the plunging motion.
本論文では舵面を有する翼の最悪突風応答解析について示す。最大応答を発生させる突風を求めるためにmatched filter theoryを用いる。その結果を、離散突風の代表的な形状である1-minus-cosine突風による応答と比較した。Matched filter theoryにより得られる応答は、エネルギーにして約2倍となり、1-minus-cosine突風よりも厳密に評価できることがわかった。さらに、舵面のヒンジ剛性がプランジ方向の応答に影響することを示す。
