The Usage of Fractal Quality for Microacceleration Data Recovery and for Measuring Equipment Efficiency Check

Application of Fractal Analysis While Designing of Family of Spacecraft for Needs of Space Industry

“…Equations (4) and (5) give more than double decrease of the real tangential inertia force of spacecraft "NIKA-T" [13] after substitution of basic parameters of the spacecraft. At that, energy losses are not taken into account there.…”

“…There is worked out an algorithm of measuring equipment efficiency check on the basis of fractal property of constructive component of microaccelerations in Ref. [13]. The algorithm is effective when constructive component dominates in microacceleration field of inner environment.…”

“…In this case accuracy can be raised using fractal analysis. Well-known method of majority control [13] can be applied for replacement of the measurement channel by fractal mathematical model of microaccelerations, which was used for measuring equipment efficiency check. Undoubtedly, accuracy of such estimation would be lower in comparison with valid effective measurement channel.…”

The Techniques to Control a Space Laboratory Orbital Motion During Conducting of Gravity-sensitive Processes on Its Board

“…New control system of orbital motion allows maintaining low microacceleration level about 10 -6 g during all operational term of space laboratory (to 60 days). Test of this control system will allow using of it also in more significant space projects [8,9]. For example, the project of reusable space laboratory "OKA-T" (figure 7) is being developed in Russia at the present time [1].…”

Numerical simulation of the resonance effect at Re-entry of a rigid body with low inertial and aerodynamic asymmetries into the atmosphere

“…In the following, using of traditional mathematical analysis methods allowed to extend the classification of the secondary resonance effects applying to the task of atmospheric re-entry of RB [6]. Other features of the task of atmospheric re-entry that affect the behaviour of the descent craft, are random character of the initial conditions on the separatrix (that lead or don't lead to the transfer into the resonance area) [7], and also the possibility of losing part of data on the craft's movement [8]. In the work [9], it is shown that the negative consequences of the resonance effects in respect to the task of atmospheric re-entry of the spacecraft with low mass and aerodynamic asymmetries can be solved with introducing the control over the amount of asymmetry.…”
