Simulation of Interaction of Aircraft with Gust and Resolved LES-Simulated Atmospheric Turbulence

Abstract

Conventionally for computation of aircraft performance uniform parallel flow at the far field of the simulation method is assumed and disturbances as present in the real earths atmosphere are neglected. To study and to recognize challenging aspects of the interaction of aircraft with disturbed oncoming flow a zonal approach for simulation of compressible fluid flow is developed and presented here. Solutions computed are used to validate predictions from the alternative low-fidelity, however computationally cheaper, method, called Disturbance Velocity Approach, and to study flight through resolved atmospheric turbulence.
