(JA) シール構造及びこれを備える回転機械
Abstract: front page image
(EN)The sealing structure (7) is provided with fins (40) that protrude from the outer circumferential surface of a rotor (5) along the circumferential direction (R), and stationary blades (30) on which an abradable film (60) is formed on the inner circumferential surface (50a) of the inner shroud (50) so as to face the fins (40), and depressions and protrusions are formed on the inner circumferential surface (50a) of the inner shroud (50) and the abradable film (60) is formed conforming to the depressions and protrusions.
(FR)L'invention concerne une structure d'étanchéité (7) qui comprend des ailettes (40), qui font saillie à partir de la surface circonférentielle extérieure d'un rotor (5) dans la direction circonférentielle (R), et des pales fixes (30) sur lesquelles un film abradable (60) est formé sur la surface circonférentielle intérieure (50a) du carénage intérieur (50) de façon à faire face aux ailettes (40), et des renfoncements et des saillies sont formés sur la surface circonférentielle intérieure (50a) du carénage intérieur (50) et le film abradable (60) est formé pour se conformer aux renfoncements et aux saillies.
(JA) このシール構造(7)は、ロータ(5)の外周面から周方向(R)に沿って突出するフィン(40)と、内側シュラウド(50)の内周面(50a)に、前記フィン(40)と対向するようにアブレーダブル皮膜(60)が形成された静翼(30)とを備え、前記内側シュラウド(50)の内周面(50a)に凹凸形状が形成されており、前記アブレーダブル皮膜(60)が前記凹凸形状に沿って形成されていることを特徴とする。
