 note = {チップフィン形状翼のフラッタ特性を把握するために基礎的な風洞実験を行った。模型を2体作り非平面翼のフラッタ解析のための実験データを得た。1体は通常の平面翼であり、もう1体は15度のキャントをもってチップフィン形状翼を構成している。チップフィン形状翼において、典型的な曲げと捩りのフラッタを起こす速度より低にある速度領域でマイルドなフラッタが観測された。それは、主翼の捩り変形モードとチップフィン上にあるマスバランスのついたラダーの回転自由度が構成したものであった。動翼のマスバランスのフラッタに対する効果の検討も行った。模型の振動試験は動的変位計測装置を使って自動的に行われた。, Wind tunnel tests were conducted to investigate the fundamental flutter characteristics of a tip-fin configuration wing. Two types of models were tested to provide experimental data for the flutter analysis of non-coplanar wings. One is a normally plain wing and the other has a cant angle of 15 deg at the tip-fin. They were tested in the 2 m x 2 m low-speed wind tunnel. On the tip-fin wing, mild flutter with limited amplitudes was observed in a certain range of speeds well below the typical violent flutter speed. It was caused by the coupling between wing torsions. and the deflection of the rotationally free rudder with mass balance. The effects of mass balance of the rudder located at the tip-fin were also studied to confirm its role in flutter prevention. Modal tests on the models were performed automatically using the Dynamic Displacement Measurement System., 資料番号: AA0004242000, レポート番号: NAL TR-1228},
