Abstract

The time resolved flow and acoustic fields around a simplified two-wheel nose landing gear configuration featuring brakes, torque link, and a detachable fairing are investigated by numerical and experimental means. The flow field is computed by a lattice Boltzmann method with a collision step based on countable cumulants. Numerical near field flow predictions are validated by experimental results from Delft University of Technology. The comparison shows the quality of the applied computational setup and methodology. The favorable noise mitigation properties of the installed fairing are discussed.
