ESDU 05001 provides a means of estimating the noise levels in one-third octave bands resulting from the combustion process within a gas turbine engine which may be either static or flying. The prediction program accompanying this Item is based on the semi-empirical SAE method.

The main input parameters that need to be specified are the mass flow rate through the engine core, the combustor inlet total pressure, the total temperature rise across the combustor and the total temperature fall across the turbine system at the maximum take-off condition.

An additional program to facilitate the generation of input files is included.
