検査を格付けすべく、各検査時点迄にチェック領域に蓄積した集中応力が検査毎に比較可能な亀裂成長を生じさせるよう、複数個の脆弱部(31)に付属する複数個の凹部(34)の構成が異なっていることを特徴とする請求項5記載の回転子。 - 監視領域(37)が回転子円板(19)のハブ(36)に接していることを特徴とする請求項6記載の回転子。
- 回転子(3)を備えた流体機械において、
回転子(3)が請求項1から7の1つに従って構成されたことを特徴とする流体機械。 - 流体機械が圧縮機(5)、ガスタービン(1)又は蒸気タービンとして構成されたことを特徴とする請求項8記載の流体機械。
- 流体機械の露出した回転子(3)の状態を検知する方法であって、
回転子(3)が、内部機構の露出状態で外部から視認可能で、流体機械の作動時に比較的非臨界性の応力が発生するチェック領域(29)を有し、
且つ内部機構の露出状態で外部から視認不能で、流体機械の作動時に比較的臨界性の応力が発生する監視領域(37)を有している方法において、
まず回転子(3)のチェック領域(29)を、亀裂(40)として生じた非致命的欠陥(39)があるかどうかを検査し、非致命的欠陥(39)があり、かつチェック領域(29)に発生した亀裂(40)が限界値を越えるような亀裂長さaを持っているときに、回転子の状態を「検査要」として検知することを特徴とする方法。 - 「検査要」の状態の検知後、回転子(3)を分解することを特徴とする請求項10記載の方法。
- 請求項1から7の1つに記載の回転子を用いる、請求項10又は11記載の方法。
