FIELD: measurement equipment.SUBSTANCE: invention belongs to measuring technique, in particular to devices for measurement of value (module) and a direction angle (an aerodynamic angle) a vector of the true airspeed of the aircraft. The device contains two wedge-shaped bodies set by the bases to opposite filling air flow that are orthogonal to each other, two devices of registration of frequencies of vortex formation behind bodies and the processing device, which is executed in the form of the calculator by means of the appropriate algorithms considering frequencies of vortex formation behind wedge-shaped bodies, Strouchal number. It measures the aerodynamic angle and the true airspeed of the aircraft. At the same time its wedge-shaped bodies are located by on one axis the one over another, and perpendicularly to the general axis of wedge-shaped bodies of a jet straightener in the form of the thin plates located on the upper and lower bases of both wedge-shaped bodies and selecting their zones of vortex formation.EFFECT: expansion of functional capabilities of a device, measuring accuracy and noise immunity increase, receiving output signals in the digital form.2 cl, 4 dwg |
