Methodical foundations of forecasting the reliability of products of aviation and rocket and space technology

Abstract

The study discusses various techniques and algorithms for determining the quantifiable characteristics of the reliability of products of aviation and rocket and space technology at the stages of research and development. The sequences of disaggregation of composite products into components and the drawing up of structural reliability schemes are given on the example of an electric rocket engine having mechanical units and electrical equipment of various types. Various methodological approaches are presented to determine the possibility of failure-free operation of the component parts of products, both with experience data on failure rates of elements and without official data on reliability. Recommendations are given to increase the VBR components, individual parts and the product as a whole.
