Abstract

A turbulence model based on a Synthetic Eddy Method has been adapted for flight simulation purposes and coupled to two FlightLab helicopter models. The model is based on the generation of a random distribution of turbulence generating Eddies within a control model surrounding the aircraft. Eddies are convected by the flow and regenerated at the inflow as they leave the simulation domain. Adjustment of Reynolds stresses and Eddy shape and sizes should allow adjustment of turbulence intensities and frequency spectra. Compared to other random turbulence models, preserving the location of the Eddies in the control volume ensures automatically that turbulence across different aircraft locations is automatically correlated. Offline and piloted flight simulation has been conducted to test the viability of the concept. Results show that the turbulence model generates upsets in all aircraft axis which result in higher workload requirements for the pilot.
