COMPLEX OF ALGORITHMS AND PROGRAMS FOR CALCULATION OF AIRCRAFT NOISE
SINOPSIS
The AERONOISE complex of algorithms and programs developed at TsAGI is considered. The noise levels on jet and screw airplanes and helicopters can be computed with the AERONOISE complex. Also, acoustic problems arising during optimization of the parameters of an air vehicle under the criterion of the minimum environmental aircraft noise level and at the acoustic zoning areas of airports and their vicinities can be solved with AERONOISE. In the current study, the part of the complex concerning the noise computation for jet airplanes at reference points is discussed. In the complex, acoustic computation of an aircraft for three levels corresponding to the different stages of design and operation of aircraft is implemented. The algorithms of the first and second levels are based on the computational gas-dynamic characteristics of the power plant and on the aircraft performance characteristics. The algorithm of the third level uses the results of the measurements of matrices of the noise levels of an engine on the open stand.
