A report is presented of a study in which the design and fabrication of a multipoint sampling rake was completed. A check-out test of the rake using a JT9D experimental engine indicated that the exhaust emission sample obtained from the rake was very close to the average of the samples obtained from the individual probes located adjacent to the 12 rake sampling points. This probe was then used to sample the exhaust emission from an experimental engine of each of the JT3D, JT8D, and JT9D engine models, plus production engines. All of the mass emission results obtained during the program were subjected to a statistical analysis. The results of this analysis were then used in a hypothetical aircraft operational cycle. Measurements of smoke, dry particulates, total particulates, aldehydes, and olefins were also recorded. (Author)
