TURBOMACHINE DISK DEFLECTOR FIXING DEVICE

摘要

FIELD: aircraft industry. SUBSTANCE: invention can be used in rotors of aircraft engines and ground industrial plants. Proposed device includes axial locking members in form of projections on surface of deflector rim located in groove on disk rim, and member to provide circumferential locking of deflector relative to disk. Groove is made with smooth changing from end face to radial surfaces. Deflector circumferential locking member is made in form of zigzag part. Invention eliminates stress concentrators and improves centering in peripheral and hub parts of deflector. EFFECT: improved reliability and repairability of construction. 3 dwg
