ABSTRACT:
In order to study the aerodynamic phenomena occurring around structures of an aircraft, particularly during ground and flight tests, an automated multichannel pressure measuring system is proposed. This system, which is entirely contained in a very small box or case (10), incorporates the pressure transducers (14) and processing software (54) for the approximate values supplied by the transducers. A multichannel or multiway valve (32) places the system in a blowing or blasting state purging the circuits in the case or rain. In this state, it is possible to check the satisfactory operation of the transducers and carry out their calibration. Therefore, the frequency with which recalibration of the system has to take place in the laboratory is greatly reduced. Advantageously, the transducers (14) are temperature-controlled.
