Title:
可動ブレードの径方向の隙間を制御するためのハウジングの取付けが改善されたタービンエンジン用の高圧タービン
Document Type and Number:
Japanese Patent JP5615808
Kind Code:
B2
Abstract:
A high pressure turbine of a turbomachine such as a turbojet, in which a control box of radial clearances of rotating blades are provided. An annular element including a determined flexibility has one end fixed to an annular support and the other end supported by a simple axial bearing with a given pressure on the upstream side of the control box. Thus, disturbing vibration loads are prevented at the attachment points of the control box with the external casing of turbines, thereby also eliminating the risk of cracks occurring.
