Abstract (en)

[origin: FR2786272A1] The probe (S) measures the physical parameters of an air flow generally directed towards the rear of the probe. The probe (S) has a structure (10,20) carrying at least a sensor (C). The structure of the probe (S) includes a part (20) of which an edge (22) generally extends in front of the sensor (C) and is shaped to create turbulence. The sensor (C), see Fig. 1d, extends into the axial region (L) of the turbulence. The turbulence is sheltered behind the structure part (20) with respect to the air flow. The sensor (C) is a temperature sensor which includes a resistance with a positive temperature coefficient, platinum or thermocouple. The structure (20) is designed to be mounted with an non zero incident angle ( alpha ) with respect to the principal direction of airflow (X).
