Portable Oxides of Nitrogen Analyzer for Electric Arc Heated Gasdynamics Test Facilities.

摘要

This Technical Memorandum describes a portable oxides of nitrogen gas analyzer designed and built by the Air Force Flight Dynamics Laboratory (AFFDL). This unit incorporates commercial gas analysis instruments which are capable of detecting both nitrogen dioxide and nitric oxide in concentrations of from 0 - 5000 ppm and 0 - 50000 ppm to an accuracy of 1% of full scale range. All the components necessary for on-site operation are incorporated into the analyzer and it is rugged enough to be moved from one location to another without impairing its reliability. The analyzer is presently being used to measure NO(x) concentrations in the exhaust from the AFFDL 50 Megawatt Hypersonic Test Leg (HTL) arc heated gasdynamic test facility.
