FORECASTING THE SURVIVABILITY INDICATORS OF SPACECRAFTS BY THE RESULTS OF THE BOARD EQUIPMENT TELEMETRIC CONTROL USING FUZZY BORDERS OF FUNCTIONING AREA

Mironov E.A., Sisyakov N.P., Shestopalova O.L.

This article describes the solution of the problem of calculating the values of the survivability indicators of the on-board apparatus of the spacecraft, which consists in obtaining quantitative estimates of the probabilities of non-passing parameters of the technical state of the on-board equipment of the spacecraft for the conditional boundaries of the tolerance field determined under the assumption of an impact on the airborne equipment of the spacecraft and the conditions for its operation influencing factors of a given intensity.

A distinctive feature of this work is a complex consideration of the influence of external factors on the airborne apparatus of the spacecraft, including the effect on both the onboard equipment itself and on the conditions of its operation. This makes it possible to use the results obtained to predict the residual service life of the on-board apparatus of the spacecraft taking into account possible adverse effects.

The article shows that the effects of external natural and artificial factors due to the undefined nature of the composition, intensity and degree of manifestation of the influencing factors can be adequately taken into account when describing the limits of tolerance tolerance fields for the onboard equipment of spacecrafts by fuzzy sets whose membership functions are estimated on the basis of a formalized representation of experience experts with fuzzy linguistic scales and are presented in the form of fuzzy boundaries I admission.

A mathematical model is presented, the composition of the input and output data is described, algorithms for solving the problem of calculating the values of the survivability indices of the on-board apparatus of a spacecraft, suitable for implementation on a PC are presented. An example is given of calculating the predicted values of the survivability indices of the on-board apparatus of the spacecraft based on the results of telemetric control of the temperature of the internal circuit of the spacecraft thermal control system.
