Abstract
【解決手段】 フェイズドアレイ超音波の使用により、エーロフォイル内部の関心領域に向けて超音波ビームを操作することができる。フェイズドアレイの使用により、検査担当者は、多数の角度を一度に監視できる。走査角度が校正範囲を超えない限り、超音波ビームの表面入射角がどのような角度であっても、検査担当者は、関心領域を監視することができる。超音波ビームは、1回の走査で様々に異なる向きを検査するように操作される。一連の変換器から構成されるリニアアレイプローブであるフェイズドアレイ変換器を使用する。変換器は、所定の時間間隔でトリガすると共に、所定の時間間隔で受信するようにプログラムされる。その後、各変換器により収集された信号は、コンピュータにより処理され、欠陥標識を観測することができるように、試験領域に対する複合視界を形成する。
