ISO-KINETIC PROBE FOR THE ANALYSIS OF THE POLLUTION OF GASES GENERATED BY AN AIRCRAFT ENGINE

摘要

Iso-kinetic probe for the analysis of thepollution of the gases generated by an aircraft engine.It comprises an air tapping tube having anupstream end inserted into a conduit wherein a gasstream flows and gas stream inlet velocity adjustmentmeans provided at an orifice of the tapping tube. Thetube has a downstream end mounted in a fixed manner ona base. The base has an outer diameter mounted in aninner diameter d of a passage bushing. The innerdiameter d of the passage bushing being sufficientlygreat so that the upstream end of the tube is suitableto fit through the inner diameter of the passagebushing. The probe also comprises a measurement chamberhaving an end connected to the base.
