GMDH method study on annular combustor noise total sound level of aircraft engine
WU Xiao-ming · 2009
We studied the total sound pressure level test data in an annular combustion chamber of aircraft engine by Grop Method of Data Handing(GMDH).Secondary regression equations of the latter generation and quite complex are constructed through simple binary quadratic regression principle and the total noise sound level equation in annular combuster of an aircraft engine is obtained giving a quite objective description of nonlinear modulating of complex nonlinear system using optimum seeking principle to clean those non-ideal terms in secondary regression equations.out.
