To detect vibrations of a rotor blade.SOLUTION: A vibration detection device 70 for an aircraft includes: a difference calculation part 72 that calculates a difference between a target value and an actual value of an angle of a spoiler 12; a threshold determination part 74 that determines whether or not an absolute value of the difference is a threshold or above; and a vibration determination part 82 that determines that vibrations are generated in the spoiler 12 when the absolute value of the difference is the threshold or above.SELECTED DRAWING: Figure 1

    【課題】動翼の振動を検出する。【解決手段】航空機用振動検出装置70は、スポイラー12の角度の目標値と実測値との差分を算出する差分算出部72と、差分の絶対値が閾値以上であるか否かを判定する閾値判定部74と、差分の絶対値が閾値以上である場合にスポイラー12に振動が生じていると判定する振動判定部82とを有する。【選択図】図1
