Изобретение относитс к измерению параметров движени и может найти применение при измерении величины и направлени вектора скорости движущегос объекта относительно среды, а также при аэро- и гипродинамических исследовани х. По основному авт. св. № 655975 известно устройство дл измерени скорости потока газа или жидкости, которое содержит источник меток, два приемника, один из которых кольцевой, а другой имеет форму сптфали Архимеда и измерительную схему.The invention relates to the measurement of motion parameters and can be used in measuring the magnitude and direction of the velocity vector of a moving object relative to the medium, as well as in aerial and hygrodynamic studies. According to the main author. St. No. 655975, a device for measuring the flow rate of a gas or liquid is known, which contains a source of labels, two receivers, one of which is circular, and the other has the shape of an Archimedes branch line and a measuring circuit.
Дл получени сигнала по скорости и направлению потока в этом устройстве производитс измерение двух временных интервалов, соогветсгвуюших времени прохожцени меткой по кольцевого приемника и ао приемника в виде спирали Архимеда.In order to obtain a signal according to the speed and direction of flow, this device measures two time intervals, according to the passage of time, the passers-by mark the ring receiver and the receiver ao in the form of an Archimedes spiral.
Дл определени направлени вектора скорости вычисл етс отношение временных интервалов. При этом формирование меток производитс с посто нной частотой 1 .To determine the direction of the velocity vector, the ratio of time intervals is calculated. In this case, the formation of tags is made with a constant frequency of 1.
Однако данное устройство не позвол ет определить непосредственно направление потока относительно задшсной оси.However, this device does not directly determine the direction of flow relative to the rear axle.
Цель изобретени - расширение функциональных возможностей за счет непоородственного определени угла направлю ни скорости потока относительно заданной оси.The purpose of the invention is to expand the functionality by non-conforming determination of the angle, directing the flow velocity relative to a given axis.
Указанна цель достигаетс тем, что в известном устройстве измерительна This goal is achieved by the fact that in a known device measuring
10 схема выполнена в виде измерител разности фаз, входы которого через усилители св заны с приемниками, при этом кольцевой приемник соединен с генгратором импульсов источника меток.10, the circuit is designed as a phase difference meter, the inputs of which through amplifiers are connected to receivers, and the ring receiver is connected to the generator of pulses of the source of labels.
