Choice of geometrical parameters of integrated scheme aircraft on the basis of high-precision mathematical modeling

The problem of increase the accuracy of choice the basic geometrical parameters of nonconventional schemes aircrafts at the expense of use at early design stages the high-precision mathematical modeling is considered. It is offered to use at a stage of aircraft aerodynamic designing for weight calculations final- element model of variable density body. On the basis of the given approach the algorithm of choice the aircraft rational geometrical parameters taking into account weight and aerodynamic efficiency is constructed. Results of application the algorithm to a problem of formation the integrated scheme aircraft shape are presented.
