Patent

CA 2394190

The invention relates to a multifunctional probe for an aircraft, especially for determining the static pressure (Ps) and the total pressure (Pt) of an airflow in the vicinity of the aircraft and the incidence (.alpha.) of the aircraft in relation to the airflow. The inventive probe comprises a mobile pallet (1) which is aligned with the axis of the airflow and which comprises at least one static pressure port (13, 14) which is situated on one side of the pallet (1), and a pressure port for measuring the incidence (.alpha.) of the pallet (1) in relation to the airflow. The probe also comprises pressure-measuring means associated with each pressure port and means for calculating the total pressure (Pt) of the airflow according the measurements taken by the different measuring means of the probe.

L'invention se rapporte à une sonde mulfonctions pour aéronef à déterminer notamment la pression statistique (Ps) et la pression totale (Pt) d'un écoulement d'air située au voisinage de l'aéronef et l'incidence (.alpha.) de l'aéronef par rapport à l'écoulement. La sonde comporte une palette mobile (1) destinée à s'orienter dans l'axe de l'écoulement d'air, la palette mobile (1) comprenant au moins un orifice (13, 14) de prise de pression statique située sur un côté de la palette (1) et une prise de pression destinée à mesurer l'incidence (.alpha.) de la palette (1) par rapport à l'écoulement. La sonde comporte en outre des moyens de mesure de pression associés à chaque prise de pression et des moyens de calcul de la pression totale (Pt) de l'écoulement en fonction des mesures réalisées par les différents moyens de mesure de la sonde.
