Method of measuring pressures parietal for the study aerodynamic of a mechanical piece in a wind tunnel

摘要

The present invention relates to a method of measurement of the parietal pressures for the study of the aerodynamic of a mechanical part by a blower. According to this process, there is a simulation model (10), representative of the external geometry of the mechanical part, it determines a plurality of points of measurement of pressure (p 1) in at least one zone to be studied of the mechanical part (10) is carried out, on the simulation model (10), from each point of measurement of pressure (pi), a pipe of small cross-section, which opens into a connection zone (12) is representative of a zone of the mechanical part is not sensitive to the air-heating plane, and each outlet cross-section (if) of a pipe of small cross section in said connection zone (12), it is connected a flexible pipe conveying the signals of the measured pressure up to a device of the type of sensor placed out of the flow.
