CONSTRUCTION AND ERRORS OF THE AIR SIGNAL SYSTEM BASED ON THE VORTEX METHOD

Annotation

The reasons for complication of the design, increase in weight and cost of traditional systems for measuring aircraft air signals based on aerometric, aerodynamic and vane methods for measuring pa-rameters of incoming air flow are considered. These reasons are reported to limit the scope of such sys-tems and determine the relevance of the development of an air signal system based on the vortex meth-od using one integrated flow sensor. Analytical models for signals in the measuring channels of an orig-inal system of subsonic aircraft air flow signals, based on a vortex sensor of the aerodynamic angle and air speed, are presented. The instrumental and methodological errors of the measuring channels of the air signal system based on the vortex method are analyzed.
