摘要

The control of the gas temperature distribution at the combustor exit is an important factor today in ensuring the durability of turbine nozzles and blades by offsetting the extremely high combustor exit gas temperature for modern jet engines. Since the maximum output condition of an actual engine cannot be simulated in a rig test due to the limited capacity of the test equipment, the peak temperature factor of the combustor under the most critical temperature conditions cannot be determined. There are almost no data which have successfully established correlativity for the peak temperature by a parameter. This study was carried out in an effort to establish such a parameter, which could be useful for estimating the peak temperature factor under high loading. The combustor operating conditions were parametrically varied as to the pressure, temperature, airflow, and temperature rise for the combustor with pressure atomizing fuel nozzles and the combustor with airblast type fuel injectors, and their effects on the peak temperature factor were examined in order to find correlations by which to establish the parameter. θ parameter “(P{sub}3){sup}1.75·A{sub}(ref)(D{sub}(ref)){sup}0.75·exp(T{sub}3/300)/Wa" revealed the good correlations with the peak temperature factor.
