| Abstract |
The problem of the designing bodies of minimum drag for a specified area of the base and a specified area of the ("windward") surface around which the flow occurs is considered in the approximation of an arbitrary localized interaction model. New necessary conditions for minimum drag are obtained which are stronger than the Legendre condition. It is shown that, in the approximation used, the optimal configurations in the general case contain end faces and cylindrical segments of the boundary extremum, which appear due to the existence of limits of applicability of local models. It is established that the solutions previously obtained are incomplete. A complete solution of the problem is constructed. |
