Description
(5) УСТРОЙСТВО дл ИЗМЕРЕНИЯ ПРИВЕДЕННОЙ СКОРОСТИ . ВРАЩЕНИЯ ВАЛА ГАЗОТУРБИННОГО ДВИГАТЕЛЯ(5) DEVICE FOR MEASURING RADIATED SPEED. ROTATION OF THE SHAFT OF A GAS TURBINE ENGINE
II
Изобретение относитс к измерительной технике и может быть использовано дл измерени приведенной скорости вращени вала газотурбинного двигател .The invention relates to a measurement technique and can be used to measure the reduced rotational speed of a gas turbine engine shaft.
Известно устройство дл измерени скорости вращени , представл ющее собой цифровой измеритель временного интервала, формируемого датчикам оборотов A device for measuring the speed of rotation is known, which is a digital gauge of the time interval formed by the rotational speed sensors.
Однако дл измерени приведенной скорости с использованием такого устройства требуетс дополнительное вычислительное устройство.However, an additional computing device is required to measure the superficial velocity using such a device.
Наиболее близким к предлагаемому вл етс устройство дл измерени приведенной скорости вращени вала газотурбинного .двигател , которое содержит частотный датчик скорости вращени и датчик температуры заторможенного потока воздуха на входе двигател , соединенный с функциональным преобразователем J.Closest to the present invention is a device for measuring the superficial rotational speed of a shaft of a gas turbine engine, which contains a frequency sensor for the rotational speed and a temperature sensor for the inhibited air flow at the engine inlet, connected to a functional converter J.
Однако указанное устройство обладает недостаточно высокой точностью измерени , особенно на переходных режимах работы двигател .However, this device does not have a sufficiently high measurement accuracy, especially in transient modes of engine operation.
Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.
Поставленна цель достигаетс тем, что устройство снабжено опорным и управл емым генераторами импульсов двум управл емыми делител ми .часто10 ты, реверсивным счетчиком, двум элементами И и блоком управлени , причем функциональный преобразователь выполнен с цифрЬвым выходом, подключенным к управл ющим входам The goal is achieved by the fact that the device is equipped with a reference and controlled by a pulse generator with two controllable dividers, a reversible counter, two AND elements and a control unit, the functional converter with a digital output connected to the control inputs
