Abstract

In paper a method of structural-parametric optimization of constructive-technological patterns of low-aspect lifting surfaces is proposed. The design structure is understood as the constructive-technological pattern. The choice of the best possible constructive-technological pattern is made as a result of the decision of an identification problem of alternative constructive-technological patterns with a preliminary found optimal design. The optimal design is a minimum of weight distribution of a material, satisfying with the requirement of strength and aeroelasticy. An example of structural-parametric optimization of constructive-technological patterns oj low-aspect lifting surfaces is given.
