SINGLE-COMPONENT JET ANGULAR VELOCITY METER Russian patent published in 2023 - IPC G01P3/26 

FIELD: measurement technology.

SUBSTANCE: invention can be used to measure the angular velocity of moving objects. A single-component jet angular velocity meter comprises a housing 1, a working chamber 2, a supercharger 3 connected through an ionization chamber 4 to a forming nozzle 5, a nozzle 6 with a diameter larger than the diameter of the forming nozzle 5 installed coaxially with it and connected to the supercharger 3, a regulating throttle 7 installed between the supercharger 3 and the ionization chamber 4, and a differential ion receiver made in the form of two flat electrodes 8 and 9 connected to the electrical measuring circuit 10. The structure of the meter additionally includes an ion current adder 13, consisting of the first and second resistors 11 and 12, an ion current stabilizer 14, with the first terminals of the resistors connected, respectively, to a pair of electrodes of the differential ion receiver and the inputs of the electrical measuring circuit 10, and the second ones are connected together and connected to the control input of the ion current stabilizer 14, the output of which is connected to the input of the ionization chamber 4.

EFFECT: increased accuracy of measuring angular velocity when destabilizing factors of the degree of ionization appear.
