Measurement acquisition device with a sliding attack section on a support

Abstract

The present invention relates to a measurement acquisition device comprising a support (2) adapted to be attached to a turbomachine test bench, a leading edge (3) adapted to face a gas flow circulating in the turbomachine test bench when the support (2) is attached to the turbomachine test bench, and a sensor (6) arranged on the leading edge (3) to acquire a characteristic measurement of the gas flow when the support (2) is attached to the turbomachine test bench. The device is characterized in that the leading edge (3) defines a groove, and the support (2) comprises a rail extending in the groove so as to form a sliding connection. The leading edge (3) is mounted detachably relative to the support (2). Figure for the abstract: Fig. 4

Claims

slide being formed by the groove delimited by the trailing part and the support rail (2).

12. Measurement acquisition device (1) according to any one of claims 9 to 11, • the attacking part (3) has an external surface (31), • the trailing part (4) has a second external surface (41) which extends tangentially from the external surface (31).

13. Device (1) for acquiring measurements according to any one of claims 9 to 12, • the sliding link allows a translation of the attacking part (3) relative to the support (2) in a direction of translation, • in a transverse plane which is orthogonal to the direction of translation, the attacking part (3) and the trailing part (4) completely cover the support (2).

14. Assembly comprising: • A test bench for turbomachine (10), • a measurement acquisition device (1) according to any one of the preceding claims, the measurement acquisition device (1) being fixed to the test bench for turbomachine (10) such that the driving part (5) faces a flow of gas circulating in the test bench for turbomachine (10).

15. A method using a measurement acquisition device (1) according to any one of claims 1 to 13 or an assembly according to claim 14, the method comprising: • detaching the attacking part (3) from the support (2) by translating the attacking part (3) relative to the support (2) via the sliding link, • attaching another attacking part to the support (2) by translating the other attacking part relative to the support (2) via the sliding link, wherein the other attacking part is different from the attacking part (3).
