The e!ect of turbulent loading on the noise radiated by an advanced aircraft propeller is assessed using a spectral conditioning technique which allows the inclusion of the non-linear e!ects associated with source rotation. The method allows the steady-source noise at a microphone to be estimated by
In this paper the development of a convective acoustic analogy equation for the case of a moving source in a moving medium is described and the resulting form is compared to that of Blokhintsev and that of Ffowcs Williams and Hawkings. Computational results for a modern propeller with supersonic tip
