Beschreibung
Zusammenfassung:	The invention relates to a fuselage Pitot-static tube comprising three groups of orifices for determining the total pressure (2), static pressure (3) and angle of attack (6, 7), and an axisymmetric body (1) and strut (5) for mounting an anti-icing system having, arranged between them, airways (10) and electric heating elements (8). The orifices for determining the angle of attack are arranged on the strut, whose cross section is constructed in the form of a subsonic aerodynamic profile with a rounded-off nose or a tapered nose, and are arranged between the nose of the profile and the position of its maximum thickness. L'invention concerne une prise statique du tube Pitot de fuselage comprenant trois groupes d'orifices permettant de déterminer la pression totale (2), la pression statique (3) et l'angle d'incidence (6, 7); ainsi qu'un corps asymétrique (1) et un mât (5) permettant de monter un système antigivrage et comportant, entre eux, des voies d'air (10) et des éléments de chauffage électrique (8). Les orifices de détermination de l'angle d'incidence sont montés sur le mât, dont la coupe transversale est en forme de profil aérodynamique subsonique avec une partie avant arrondie ou effilée, les orifices étant disposés entre la partie avant du profil et sa partie d'épaisseur maximale.
