The object of the work described in this report has been the characterization of particulate-bound chemicals emitted from military aircraft, both as they are emitted and as the exhaust ages. Three Air Force turbine engines (TF33-P3, TF33-P7, and J79C) were examined in this study, using engine test cells at Tinker AFB OK. Emissions were collected at...

Context 1
... characterization of the exhaust of the engines during this study was the principal objective of the companion task for this work and is reported elsewhere in detail (Reference 5). The data in Table 7 represent a summary of a portion of that work and are presented here for the sake of completeness. ...
Context 2
... is not intended to discuss in detail the composition of the engine exhaust gas, since that is done elsewhere (Reference 5). Only the salient features of the data from Table 7 The engines differ considerably, however, in the concentration of total hydrocarbons found in their exhaust, with the J79 engine exhaust containing, typically, one-third the THC found in the TF33 exhausts. The data point for the TF33-P7 engine at 75 percent power seems low when compared with the remain- ing data obtained. ...
Context 3
... PAH concentrations seen in Table 10 basically follow the trends seen in Table 7 While general statements regarding trends can be made, based on these data, there is too much variability between measured compounds to relate the whole set of PAH concentrations measured under one set of conditions to the set measured under other conditions. One cannot say, for example, that the TF33-P7 idle exhaust contains 10 times the PAH concentration at 30 percent power, although this is true for some of the compounds detected. ...
