On the fractal properties microaccelerations

In this paper the fractal property of the internal environment of space laboratory microaccelerations that occur. Changing the size of the space lab leads to the fact that the dependence of microaccelerations from time to time has the property similar to the self-affinity of fractal functions. With the help of microaccelerations, based on the model of the real part of the fractal Weierstrass-Mandelbrot function is proposed to form the inertial-mass characteristics of laboratory space with a given level of microaccelerations.

Research of influence of temperature deformations of the big elastic elements on dynamics of a space vehicle

At this project considers the problem of analysis temperature deformation of elastic elements of the spacecraft. Spacecraft periodically appears in the earth's shadow on the sunny side when moving from the orbit. Abruptly changing the temperature field of large elastic elements can affect the dynamic characteristics of the spacecraft. This is important when dealing with the implementation of the gravity-sensitive processes on board.

Buffon Needle Problem Application to Space Exploration

In this article the possibility of application of classical Buffon needle problem to the investigation of orientation engine firing problem has been investigated. Such an approach makes it possible to get a reliable EP of this undesired event without using a more complicated analysis.

Construction of Microaccelerations Fractal Model on the Basis of Weierstrass-Mandelbrot Function

In work the opportunity of construction fractal estimation of low-frequency component microaccelerations with the help of the valid part to Weierstrass-Mandelbrot function at identically zero phase is statistically proved. The proof will be carried out with the help of correlation factor and nonparametric rang criterion Cox - Stuart.
