Patent ID: 8695412

Claim:
A probe for measurement of the local angle of attack of a fluid flow along a wall, the probe comprising: a probe body designed to be fixed to the wall and aligned in a main direction, around which the angle of attack can be measured within a range of angle of attack, at least five pressure sampling ports disposed over a nose of the probe body, the nose being situated on one side of the body with respect to the largest cross section of the body perpendicularly to the main direction, the nose forming a surface locally perpendicular to the angle of attack inside of the range, pressure measurement means associated with the pressure sampling ports and calculation means capable of determining an angle of attack of the flow with respect to the main direction of the probe body as a function of the pressures measured by the pressure measurement means, wherein the calculation means are configured for choosing from amongst the pressure sampling ports those allowing the best measurement precision of the local angle of attack and for calculating the local angle of attack with respect to the main direction using the pressure measurements carried out in the chosen pressure sampling ports.
