Moving Spatial Turbulence Model for High-Fidelity Rotorcraft Maneuvering Simulation

A moving spatial turbulence model is developed for rotorcraft maneuvering simulation under different flight conditions. The recursive algorithms are adopted to its distributed longitudinal components, which correlated with the lateral and vertical axes form a local field. flow field constrained around by following movement, corresponding components updated at constant interval. statistical properties along longitudinal, lateral, directions have been validated against von Kármán theory. synthetic environment consisting of dynamics pilot constructed demonstrate effectiveness model. Its performance comparing power spectral densities both responses controls in test data. piloted results on an Approach-to-Hovering task show that handling qualities ratings susceptive level significantly increase when performing aggressive controls. also accurately predicts expected effect varied aircraft speed, wind intensity, stability augmentation system rating turbulence.
