Variational Analysis and Euler Equation of the Optimum Propeller Problem, to extend the solution to non-planar blades. First, we find a class of functions (the circulation along the blade axis) for which the thrust and the aerodynamic drag moment are well defined. In this class, the objective functional is proved to be strictly convex and then the global minimum exists a

Another View on Planar Anisotropy: The Polar Formalism,sors of any rank using invariants and angles. As such, it is particularly suited for representing anisotropic properties, in particular elasticity..In this paper, we give a brief account of the fundamentals of the polar formalism, stressing in particular the role played by the polar invariants on th
