PROBLEM TO BE SOLVED: To provide devices which may reduce stresses experienced by a wingtip device and wing.SOLUTION: A flow interrupting device 100 may cause a flow to separate from a wingtip device 102 at a desired angle of attack. The flow interrupting device may be coupled to a leading edge of the wingtip device, where a flow disruptor 112 may be configured to alleviate a load on the wingtip device. The flow disrupter may comprise an edge 110 that extends into a boundary layer at a threshold angle of attack that may disrupt the boundary layer and cause the flow to separate from the wingtip device. This separated flow may reduce stresses experienced by the wingtip device and wing during various flight conditions where a transverse flow is encountered.

    【課題】翼端デバイスおよび翼によって経験される応力を減少させることができるデバイスを提供する。【解決手段】流れ遮断デバイス100は、所望の迎え角で流れを翼端デバイス102から分離させることができる。流れ遮断デバイスは、翼端デバイスの前縁部に連結され得、流れ中断器112が翼端デバイスにかかる荷重を軽減するように構成され得る。流れ中断器は、閾値迎え角で境界層に延在する縁部110を備えてもよく、これは、境界層を中断し、かつ流れを翼端デバイスから分離させ得る。この分離された流れは、横断流に遭遇するとき、様々な飛行状態での翼端デバイスおよび翼が経験する応力を減少させることができる。【選択図】図1
