Abstract

The present invention relates to a test bench for a turbomachine rectifier, the turbomachine rectifier comprising a hub (4) and several blades arranged in each housing (41) of the hub (4) by means of a blade root fixed to a flange (52) for securing the blade root in the housing (41); the test bench comprising: - measuring equipment configured to support a turbomachine rectifier; and - instrumentation cables (11); and - a retaining cupola (9) intended to be arranged inside each housing (41), the retaining cupola (9) being configured to guide the instrumentation cables (11) in the hub (4) in order to prevent any contact between the instrumentation cables (11) connected to the rectifier blades and the measuring equipment during the turbomachine rectifier test.

Claims

wherein each housing (41) comprises a retaining wall (42) comprising an introduction window (43) suitable for allowing the flange (52) and the holding dome (9) to be inserted into the housing (41) and suitable for retaining the flange (52) in the housing (41) following a rotation of the flange (52) by a fraction of a turn.

6. A test bench (8) according to claim 4, wherein the flange (95) for securing the holding dome (9) comprises an adhesive configured to secure the flange (95) of the holding dome (9) to the housing (41).

7. Assembly (10) for testing a rectifier (3) of a turbomachine (1), comprising a test bench (8) according to one of claims 1 to 6 and a rectifier (3) of a turbomachine (1).

8. An assembly (10) according to claims 5 and 7, wherein the rectifier comprises clamping members (7) configured to clamp the flange (52) and the blade root (51) to the retaining wall (42) so as to immobilize the blade root (51) in the housing (41) in a desired angular position.

9. Turbomachine (1) comprising a rectifier (3) configured by means of a test bench (8) according to one of claims 1 to 6, or an assembly (10) according to one of claims 7 and 8.
