To provide a failure detection method capable of detecting a rudder failure of an underwater traveling vehicle with an excellent detecting ability.SOLUTION: A failure detection method of one aspect includes a first step, a second step, and a third step. The first step measures a roll angle of an underwater traveling vehicle traveling with a specific pitch angle and a specific yaw angle under a test environment where the normality of multiple rudders is confirmed, the second step measures the roll angle of the underwater traveling vehicle traveling with the specific pitch angle and the specific yaw angle under an operational environment where the normality of multiple rudders is unconfirmed, and the third step detects one rudder failure of multiple rudders based on the difference between the roll angle of the underwater traveling vehicle measured under the test environment and the roll angle of the underwater traveling vehicle measured under the operational environment.SELECTED DRAWING: Figure 3
【課題】優れた検知能力で水中航走体の舵の故障を検知する。【解決手段】一態様の故障検知方法は、複数の舵の正常性が確認された試験環境下において、特定のピッチ角又は特定のヨー角で航走する水中航走体のロール角を計測する第1ステップと、複数の舵の正常性が未確認の運用環境下において、特定のピッチ角又は特定のヨー角で航走する水中航走体のロール角を計測する第2ステップと、試験環境下で計測された水中航走体のロール角と、運用環境下で計測された水中航走体のロール角との差に基づいて、複数の舵のうち1つの舵の故障を検知する第3ステップと、を含む。【選択図】図3
