Control over maintaining accuracy of integrity of reference surfaces of spacecraft components in their joint functioning at various stages of design

The paper deals with ensuring the accuracy of integrity of spacecraft components’ reference surfaces at various stages of design. It is shown that the main problem consists in the fact that the accuracy of integrity of the reference surfaces of the components making up the complex is maintained in the framework of the internal structure of a part. We propose a method of control over ensuring the accuracy of integrity of spacecraft components’ reference surfaces at various stages of design in the framework of their external structures. The method is implemented by introducing the coordinate system of the complex into the scheme of the complex of components that perform interrelated service functions. Concepts and definitions are introduced in the framework of the method that make possible formal representation of accuracy of integrity of the components’ reference surfaces in the form of a set of pairs of points the appropriate annotated dimensions are fixed on. Graphical interpretation of the method at the stages of development of technical requirements for the components is presented. An example of potential implementation of the method at the stage of design documentation development is given.
