EMISSION SAMPLE PROBE INVESTIGATION OF A MIXED FLOW TF30 TURBOFAN ENGINE

An investigation of the emissions in the exhaust plume of mixed-flow TF30 turbofan engine was conducted to optimize the shape, size, and location of fixed probes for acquiring representative emission samples. Traverse measurements of 121 points over the exhaust nozzle were accomplished with the sample points located on a 2-inch-square grid. The average emission levels, contours, and profile distributions were determined. Exhaust emissions were measured with four mixing multihole averaging probes in the core exhaust, the engine turbine discharge pressure probes, and an experimental diamond probe design. Results indicate that the 12-point diamond probe provides representative exhaust samples from mixed-flow TF30 engine. (Author)
