DEVICE AND METHOD FOR DETERMINING THE SPEED AND/OR THE DIRECTION OF A FLUID FLOW.

摘要

The invention relates to a device for determining the speed and/or the direction of a fluid flow close to an element exposed to said flow, such as a sail, said device comprising at least one dog-vane (1). The device further includes at least one flexible strip (2), one region (5) of the strip being fastened to the element (7) exposed to said flow and another region (15) of the strip being free relative to said element, so as to enable the strip and said free region extending substantially parallel to said element to flex, said dog-vane being fixed via one of its ends to said free region of the flexible strip. The device includes conversion means (3, 3', 3A, 3B, 3'A, 3'B, 3C, 3D, 3'C, 3'D) for converting the deformations undergone by said strip into an electrical signal, relative to a reference position, and processing means (4) for processing said electrical signals.
