Introduction The suggested invention relates to attitude control system of a spacecraft. ... Systems without interaction with ambient (Systems with jet engines) Here, for instance, we can put systems, which can generate torque because of jettisoning any particles or gas. ... The main element of the suggested attitude control system is an electrical motor, which main feature is absents of a stator. ... 3 Block diagram of an attitude control system on a jet engines base. ... It is a system with| | ...

... We show that broadband energy spectra of GRS 1915+105 during all these spectral states can be adequately presented by two bulk motion Comptonization (BMC) components: a hard component (BMC1, photon index 1 = 1.7ґ3.0) with turnover at high energies and soft thermal component (BMC2, 2 = 2.7ґ4.2) with characteristic color temperature 1 keV, and the redskewed iron-line (LAOR) component. We also present observable correlations between the index and the normalization of the disk "seed" component. ...
