Rectifier-intermediate casing assembly for turboshaft engine e.g. turbojet, has blocking unit blocking rotation of internal ring with respect to casing, where unit is attached with internal ring by abutment in circumferential direction

摘要

The assembly has a rectifier (10') placed upstream of an intermediate casing (52) and including two cylindrical coaxial internal and external rings (12, 14). Downstream end of the external ring is fixed at the casing by a standard female screw. Downstream end of the internal ring is mounted on cylindrical edge upstream (80) of the casing. A blocking unit blocks the rotation of the internal ring with respect to the casing. The blocking unit is fixed at the casing and attached with the internal ring by an abutment in circumferential direction.
