Algorithm of choice the rational parameters of the wing in view of aerodynamic and weight efficiency

Building-up the algorithm of a choice of rational geometrical parameters of the nonconventional aerody-namic arrangement wing is considered. As function of the purpose magnitude of take-off mass is used. The algorithm allows to consider in complex influence of geometrical parameters on weight and aerody-namic efficiency. For evaluation of aerodynamic performances the method of discrete curls is used. For an estimation of construction weight it is offered to use a method based on finite-element model of vari-able density body and new dimensionless criterion of construction power perfection. The method is veri-fied on a problem of optimization the parameters of a trapezoidal wing.
