This model is representative of a simplified helicopter structure subjected to a monopole load applied in the exterior air space and represented by a BEM fluid.
The aim of this model is to predict pressure distribution at a frequency of 1000 Hz.
The monopole load is supposed to represent the main rotor noise which is the most significant noise source on a helicopter.
As this is an uncoupled BEM problem , FMM (FAST MULTIPOLE METHOD) solver is used to obtain the solution.
