To provide an abnormality detection device capable of appropriately detecting abnormality of a rotary wing unit in which a plurality of rotary wings are coaxially disposed.SOLUTION: A controller 2 detects abnormality of a rotary wing unit 11 in which two propellers 111a, 112b are coaxially disposed. The controller 2 includes a storage unit 22 in which a correlation between the propellers 111a, 112a at the time of normal operation is prestored, the controller being configured to detect the abnormality of the rotary wing unit 11 on the basis of the correlation between the propellers 111a, 112a at their actual run and the correlation stored in the storage unit 22.SELECTED DRAWING: Figure 1 【課題】複数の回転翼が同軸上に配置された回転翼ユニットの異常を適切に検出することが可能な異常検出装置を提供する。【解決手段】コントローラ２は、２つのプロペラ１１１ａおよび１１２ａが同軸上に配置された回転翼ユニット１１の異常を検出するものである。コントローラ２は、プロペラ１１１ａおよび１１２ａについての正常な運転時の相関関係を予め記憶する記憶部２２を備え、プロペラ１１１ａおよび１１２ａの実際の運転時の相関関係と、記憶部２２に記憶された相関関係とに基づいて、回転翼ユニット１１の異常を検出するように構成されている。【選択図】図１
