To suppress noise and machine body vibration caused by a pressure fluctuation of a storage part storing a flap.SOLUTION: A main wing comprises: a base wing; a flap provided on a rear side of the base wing; a storage part provided on the base wing and storing the flap; fairings provided below the storage part and covering a flap movement mechanism for moving the flap; and a block member provided in the storage part so as to be provided between the fairings, and blocking air flowing in a wing width direction in the storage part. According to the structure, before occurrence of a feedback pressure fluctuation in the storage part, an air flow followed by variation in the shield member arranged in the storage part can be blocked. As a result, occurrence of self-excited vibration can be suppressed and increase in pressure fluctuation at a specific frequency can be suppressed.SELECTED DRAWING: Figure 1

    【課題】フラップを格納する格納部の圧力変動を起因とした騒音、機体振動を抑制する。【解決手段】主翼は、母翼と、母翼の後方に設けられたフラップと、母翼に設けられ、フラップを格納する格納部と、格納部の下方に設けられ、フラップを移動させるフラップ移動機構を覆うフェアリングと、フェアリング間に位置するように格納部内に配置され、格納部内を翼幅方向に流れる空気を遮る遮蔽部材と、を備える。この構成により、格納部内でフィードバック的な圧力変動が生じる前に、格納部内に配置された遮蔽部材で変動を伴う空気流を遮ることができる。その結果、自励振動の発生を抑制し、特定の周波数での圧力変動が大きくなることを抑制することができる。【選択図】図1
