CFD Study of a Retractable Nose Landing Gear

摘要

Computational fluid dynamics is used to calculate the turbulent flow field around a simplified model of a retractable aircraft nose landing gear. The Reynolds-averaged Navier-Stokes simulations are performed using a commercial finite volume-based code in conjunction with a dynamic meshing technique. The method allows the computational grid to be continuously adapted to the changing geometry, while following the flow evolution. The present results demonstrate the effectiveness of using this numerical approach to predict the transient aerodynamic loads acting on the landing gear strut and doors during the entire deployment phase.
