| Abstract | Determination of the emission levels from gas turbine engines operating in the afterburning mode has proven to be an extremely difficult task. This report provides analysis of two techniques for the measurement of exhaust emissions from afterburning engines, and presents the Air Force Plume Method (where emission levels are determined down stream of the exhaust where gas reactions are complete) as the preferred method. However, in limited area test environments, the Near Plume Method (where emission levels are determined at the exhaust nozzle) is an acceptable alternative of determining the emission levels from afterburning gas turbine engines. |
