Universal iglotrubchaty probe for gas-dynamic parameters of high-speed flows in turbomachinery

摘要

1. Universal iglotrubchaty probe for measuring the parameters of high gas-dynamic flows in turbomachinery comprising receivers static and total pressure receiver for measuring the direction of flow, the case in which they are arranged extraction pipes, and the limb, for the reference angle position, mounted on the housing, characterized in that the static pressure receiver is in the form of a hollow needle with a maximum ratio of its diameter to its length, where d - maximum diameter of the needle; l - length of the needle, on which there are symmetrically arranged lateral openings, the total pressure receiver is formed as a tube with a countersunk receiving opening beneath the hollow needle after the lateral hole and the detector for measuring the direction of flow is composed of two tubes disposed symmetrically on either side of the hollow needle after its lateral openings, wherein the receiving aperture tube are chamfered and the axes are parallel to all receivers, and the receivers axis static and total pressures lie in the same horizontal ploskosti.2. The probe according to claim 1, characterized in that the inlet openings of the receiver to measure the direction of flow are chamfered at the same angle.
