Since, as a rule, there are several such PSTs on an aircraft, this results in a marked reduction in weight and aerodynamic drag, and savings in the required electric power in conjunction with a simultaneous increase in the accuracy of measurement of the angle of attack. All this permits a substantial increase in the competitiveness of the proposed fuselage Pitot-static tube.

Fuselage pitot-static tube

The invention relates to a fuselage Pitot-static tube comprising three groups of orifices for determining the total pressure ( ), static pressure ( ) and angle of attack ( ), and an axisymmetric body ( ) and strut ( ) for mounting an anti-icing system having, arranged between them, airways ( ) and electric heating elements ( ). 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.
