FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment; it can be used to measure speed parameters and aerodynamic angles in air signal systems of aircrafts. A three-axis airspeed meter is characterized by the that, in a streamlined case along each spatial axis, there are two nozzles of direct and reverse flows of jet auto-generators with flow chambers protruding outside the case, while the oscillation frequency of pneumatic pressure signals of the jet auto-generator is converted by a pneumo-electric converter into an electrical signal and transmitted via connectors via an electric cable to a microprocessor, in which airspeed vectors are determined, and the residual air flow from the chamber is output outside the case through an outlet nozzle.
EFFECT: simplified construction of a true airspeed measurement system.
