概要

• 論文の詳細を見る

• Lift fluctuations of a cambered blade with angle of attack under periodic gusts with ununiform amplitude were studied by using vortex theory under the assumption that the gust amplitude on an airfoil varies linearly as described W (b + ax). Consequently it was clarified that the developed theory is valid by comparing with other results and that the ununiformity of gust amplitude gives strong effects on the fluctuating lift for small reduced frequency but does not for large reduced frequency.
