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 the pollution of the gases generated by an aircraft engine. It comprises an air tapping tube having an upstream end inserted into a conduit wherein a gas stream flows and gas stream inlet velocity adjustment means provided at an orifice of the tapping tube. The tube has a downstream end mounted in a fixed manner on a base. The base has an outer diameter mounted in an inner diameter d of a passage bushing. The inner diameter d of the passage bushing being sufficiently great so that the upstream end of the tube is suitable to fit through the inner diameter of the passage bushing. The probe also comprises a measurement chamber having an end connected to the base.
