Airfoil design by the method of singularities via parametric optimization of a geometrically constrained least squares object function

The present report describes a method for the design of airfoils in incompressible flow which, subject to geometrical constraints generate approximately a given distribution of the pressure coefficient along the projection of the airfoil chord on an axis parallel to the onset flow. The flow is simulated by means of a distribution of...

An hierarchic multi-suppliers computer network of a research laboratory with two settlements

For the aerospace laboratory NLR in the Netherlands the considerations are discussed that formed the basis of along-term plan to realize an optimal computer network. In the optimization process up to now the laboratory switched from a situation in which in each of both settlements one central close shop computer centre was available to a...
