To provide a device which suitably reduces a load acting on a main wing in an aircraft having such a wing structure that the main wing is supported by a bearing member.SOLUTION: A wing load reduction device is provided on an aircraft 1 which comprises a shell 2, a main wing 3, and a long truss member 4 of which both ends are fitted to the shell 2 and the main wing 3 and which supports the main wing 3, and reduces a load acting on the main wing 3. This wing load reduction device comprises a strain gauge 11 which detects a load acting on the main wing 3, an actuator 12 which is provided on the truss member 4 and acts a load in a longer direction of the truss member 4, and a control part. When a load acting on the main wing 3 is detected, the control part controls operation of the actuator 12 so that a load in a direction opposite to a load generated in the truss member 4 is applied to the truss member 4 by said load.SELECTED DRAWING: Figure 4

    【課題】主翼を支持部材で支持した翼構造の航空機において、主翼に作用する荷重を好適に軽減する装置を提供する。【解決手段】翼荷重軽減装置は、胴体2と、主翼3と、両端が胴体2及び主翼3に固定されて主翼3を支持する長尺なトラス部材4とを備えた航空機1に設けられ、主翼3に作用する荷重を軽減する。この翼荷重軽減装置は、主翼3に作用する荷重を検知する歪ゲージ11と、トラス部材4に設けられ、当該トラス部材4の長手方向に荷重を作用させるアクチュエータ12と、制御部とを備える。制御部は、主翼3に作用する荷重が検知された場合に、当該荷重によりトラス部材4に生じる荷重の方向とは逆向きの荷重を当該トラス部材4に作用させるように、アクチュエータ12の動作を制御する。【選択図】図4
