Abstract

The complete landing phase of a long range aircraft is studied including final approach, touchdown at the tarmac and the development of the wake. In particular end effects appearing after touchdown and propagating along the wake vortices as well as their interaction with a plate line in front of the run way are investigated. An aircraft model in high lift configuration with deployed flaps and slats obtained from a high fidelity Reynolds-averaged Navier-Stokes simulation is used to simulate the final approach until touchdown. After the wake initialization a large-eddy simulation of the vortical wake is performed until decay. The flow field is analyzed and the interaction with the ground is studied. End effects appear after touch down. They lead to a circulation decay combined with a growth of the core radius to 300%. That effect propagates downstream. The plate line further accelerates the vortex decay reducing rapidly the circulation by another 25% of the initial circulation.
