Abstract

The invention relates to a device (46) for measuring the characteristics of an air flow in an annular passage of a turbomachine, said device comprising a rod (44) which extends along a first defined axis (54), carries means for measuring air flow characteristics and sealingly engages and slides in a first tubular part (62) extended by a second tubular part (64) which along a first axis (54) sealingly passes through a slider (66) mounted in a slide for sliding along a second axis (56) perpendicular to the first axis (54), said rod (44) engaging the second tubular part (64) with an annular clearance.

Description

[0001] field of invention [0002] The invention relates to a device for measuring airflow characteristics in a turbine engine, eg a test turbine engine. Background technique [0003] Traditionally, such as figure 1 As shown, a twin-flow turbofan engine 10 includes a gas turbine 12 whose rotating shaft 14 drives a ducted fan impeller 16 , where the latter is generally located upstream of the turbofan. The air mass drawn by the engine is divided into a primary airflow (arrow A) flowing through the gas turbine 12 or the engine core and a secondary airflow (arrow B) originating from the fan 16 and surrounding the engine core, wherein the primary airflow and the secondary airflow are concentric and separated at The primary annular flow channel 18 and the secondary annular flow channel 20 circulate. [0004] In a manner known per se, the primary air stream (arrow A) is usually compressed by a low-pressure compressor 22 and then by a high-pressure compressor 24, each compressor ha...
