Application of the pairwise comparison method in the designing of composite framework of space telescopes

The problem of designing precision large-sized composite framework constructions is considered in the article. The prospects of using composite materials in large-sized supporting constructions of space telescopes are noted. The design task of creating a cylindrical construction of the telescope body of the optoelectronic complex is formulated at the verbal level and in standard form in terms of non-linear mathematical programming. The decomposition of the problem into a number of structural and parametric subtasks is proposed. The ways of solving the difficultly formalized problems of choosing structural solutions are discussed using the example of a composite framework construction of a space telescope. The choice of the concept of the framework telescope power scheme and the directive technology for its manufacture is considered in detail. To make a choice of design options and manufacturing techniques for designing the case, the method of pairwise comparisons from the system analysis was applied, taking into account the heterogeneous requirements for the product. New technical solutions are given: a shell with an external set of reinforcing ribs and the technology of its molding using elastic forming elements, confirmed by patents. Examples of framework structures from composite materials designed and manufactured using the presented methods are shown. The effectiveness of the applied methods in the design of composite framework in conditions of product requirements validity is confirmed by the parameters of the manufactured products.
