Summary:PROBLEM TO BE SOLVED: To provide an isokinetic probe that is easily disassembled and assembled and obtains air tapping speed at sufficient accuracy. SOLUTION: Isokinetic probe for the analysis of the pollution of the gases generated by an aircraft engine is provided. It comprises an air tapping tube having an upstream end 24 inserted into a conduit 14 where a gas stream flows and a 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 10. The base has an outer diameter mounted in an inner diameter (d) of a passage bushing 12. The inner diameter (d) of the passage bushing is 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 6 having an end connected to the base. COPYRIGHT: (C)2009,JPO&INPIT
