- 36 months - Full time temporary position at CNRS, Orleans, for PhD preparation.

• After having reviewed main works about lifting-line and numerical treatment of Hadamard's sens finite part integrals, we expose an implicit formulation of a steady lifting line for curved and swept wings. We first compare our results with Prandtl's lifting line theory and then validate them with a lifting surface method. We show good accordance in terms of vorticity even with highly curved wings.
• An application is shown in a configuration closed to helicopter rotor to show feasibility of our approach to this critical case.
• We propose an implicit method for unsteady curved and swept lifting line time-marching numerical computation. A numerical implementation is drawn in the most critical case of the instantaneous gust entry. The results, even for highly curved wings, are consistent relative to time discretization with good accordance with unsteady high level lifting surface methods.
