Prognostic potential of mathematical experiment planning

Abstract

The ground-experimental testing of the elements of space technology is a crucial stage in the creation of space products, in fact, this is the ground «flight» of the devices being created. And how well the operating conditions will be reproduced at this stage and the successful functioning of the devices under the expected conditions is ensured, its successful operation in real flight during the service life depends. Electronic equipment (apparatus) of the spacecraft is one of the essential elements that ensure the fulfillment of target tasks, which should confirm their readiness for the forthcoming work at the stage of ground-based experimental testing. The technology of experimental development at a time when the scientific and production association of applied mechanics (now the JSC Academician M. F. Reshetnev Information Satellite Systems) was part of the circle of enterprises that created space technology. And at the same time, the peak of research and implementation in the engineering practice of mathematical experiment planning turned out to be very timely. There was a backlog of applied work in various branches of science and technology and a minimum of work on radio-electronic topics, since the element base of the latter did not allow managing the internal parameters of electronic components, i. e., to reveal the influence of internal factors. This became an obstacle to the implementation of the capabilities of the method in research and improvement of electronic equipment. The article shows how the developers of the enterprise equipment overcame the existing limitations and successfully applied mathematical planning of the experiment for the first time in Russian space technology. Using the capabilities of the methodology, the tasks of optimization of circuit design and design implementation of devices, the choice of the element base for space equipment, the establishment of tolerances and the formation of test modes, etc. were solved.
