LES of the flow and acoustics generated by a wing installed aircraft propeller running in the vicinity of the ground
(2005) Collection of Technical Papers - 11th AIAA/CEAS Aeroacoustics Conference 2. p.1341-1354- Abstract
- A study on the noise generated by a subsonic four bladed propeller installed on a wing of an aircraft near the ground is presented. The method used is based on an acoustical analogy developed by Ffowcs Williams and Hawkings. Computations of the flow field are performed using LES with the incompressible fluid assumption, while the noise is evaluated using a non-homogeneous wave equation. The aim is to identify different noise sources produced by a propeller with lifting non-symmetric blade profile and their influence on the total sound spectrum, production and propagation.
