Abstract
The causes of variability in aircraft turbine engine emission measurements was studied. A technique for mass flow weighting of a detailed exhaust traverse data was developed. Mass flow weighted emissions data of a modified TF-30 engine were calculated and compared to other techniques used for calculating exhaust emission rates of gas turbine engines. Ambient concentrations of exhaust related gases in and around an engine test cell were monitored during gas turbine engine operation. The effect of ambient concentrations on emission measurements is evaluated. A probe manipulator capable of interchanging and rotating three multiple hole exhaust gas sampling probes was designed, fabricated and tested. Using this probe manipulator, test probe designs were evaluated and compared during one continuous engine run eliminating engine operating conditions as a test variable.
