In the following paper, we demonstrate the use of Fourier Transform as an integrated method to approach the reduction of computational cost in vortex mapping for rotorcraft flight simulators. Fourier Transform is used to analyze airwake data, both in time and spatially, to understand the structure of readily occurring air vortices on the flight deck of a Simplified Frigate Ship configuration (SFS-2). The result was both a clear and descriptive amplitude spectrum for a particular range of positions on the flight deck. The technique proved to be promising in reducing computation and has the potential to improve rotorcraft flight simulation while maintaining a high degree of fidelity.
