The purpose of research - pnauchnoe evaluation of the effectiveness of magnetohydrodynamic (MHD) management "magnetized" aircraft in the Earth's atmosphere and in interplanetary space; physico-chemical modeling and forecasting degradation of structural materials of spacecraft (SC) with prolonged exposure to the synchronous flow of plasma atomic oxygen (AO) and the electromagnetic radiation of the solar spectrum; contact (probe) diagnostics okolosputnikovoy environment with hardware development ITM of NASU and SSAU and identification of spatial and temporal distribution of the kinetic parameters of the ionospheric plasma in space experiment "Potential" on the spacecraft "Sich-2". Methods of research - theoretical and experimental, mathematical and physical modeling. Results: The technique of physical modeling of MHD interaction "magnetized" bodies (landers) with dense layers of the Earth's atmosphere and the terrestrial planets; SC-threading ionosphere plasma and solar wind plasma in interplanetary space. For the first time experimentally proved the feasibility of indestructible electromagnetic thermal protection and efficient braking landers in the Earth's atmosphere; MHD control the dynamic interaction of SC with ionospheric plasma and the plasma of the solar wind change in the orientation of the induction vector of the magnetic field of its own power with respect to the velocity vector of the spacecraft flight; - Developed a method of physical and chemical modeling of synchronous long exposure of a supersonic flow of atomic oxygen and vacuum UV (VUV + AK) on polymeric materials spacecraft in the Earth's ionosphere. Precision bench measurement ITM of NASU and Gaku weight loss, changes in the geometric dimensions of polyimides kapton-H (USA), PM-A, PM-1E (Russia), polyethylene (Ukraine) and Teflon FEP-100 (USA) supported by appropriate satellite measurements. For the first time, depending on the degradation of the polymer films fluence AK EUV flux density and exposure to AA + VUV, to predict properties of materials change over time during the period of operation of the spacecraft. It was established experimentally that for polymers containing-ing as part of the monomer CH group when exposed to VUV + AK holds a synergistic effect of accelerated degradation of materials. It is shown that the synergistic effect takes place in orbit 400 km above the average level of solar activity for the spacecraft with a lifetime of more than 2 years (the rate of degradation, erosion polymers increased several times); developed the theory, methodology contact (probe) flow diagnostic laboratory and ionospheric nonequilibrium rarefied plasma. It is shown that the scientific equipment, the theory and methodology of probe diagnostics, developed in the ITM of NASU and SSAU it possible to identify the spatial and temporal distribution of the kinetic parameters of the ionospheric plasma, measured on spacecraft "Sich-2" in the space experiment "Poten-tial": localization south and northern auroral peaks in F2 - the polar ionosphere, magnetic anomalies, as well as the epicenters of earthquakes originating on the ground tracks at the time of flight of the spacecraft. Scope - mechanics of liquid, gas and plasma; space materials; ionospheric plasma physics; Space priborostroe. The results can be used in the preparation of scientific experiments on the diagnosis of the ionospheric plasma in the Ukrainian spacecraft. Product Description popup.authors Бадель К.А. Кочубей Г.С.
