System Analysis of Global Space Power Problem LEONID LATYSHEV1 The development of Earth power generation has accelerated with great significance. At present the total power makes up 10 kWt, while the mankind, it will be necessary 10 kWt, but this is 0.1% of the power, which Earth gets from the Sun. It appears, that in 30-50 years the grave restrictions constrained both with the power generation itself and with different ecological consequences. It has been shown with scientific analysis, that it is impossible to solve these problems with any contemporary means on Earth. At the same time one must take into consideration that a new power system development will take 30—50 years to develop. Therefore now is the time to put into practice a scientific research and development work plan. The importance and significance of this outlook, strengthens the influence of diverse concept in industrial, financial, sociological and humanitarian aspects. They compromise a system of methods in research of great importance. Today, it is possible and necessary to begin research of Space Power System development problems. Let us consider some of these problems. Apparently, in the first stage of the research it is advisable to use up to date scientific ideas and even achievements of engineering. The solar energy utilization concept has gained the recognition up to date. The problems of way of transformation of this primary energy are not solved. Photoelectric converter (PEC) merits are described in detail, but difficulties, such as electric high-power station development connected with this, are hardly mentioned. Their optimum parameters remain vague so far. OPEC energy is efficient and essential. The cost and delivery cost of solar energy transformation into microwave radiation (MW-radiation) energy, is circuit complicacy, etc... Estimations give evidence of that with average efficiencies of PEC which is not costly and therefore preferable. Up to now there have been no comprehensive investigations, in the progress of solar energy concentrators and receivers. It is not clear how high-powered solar turbine plants use conditions, especially, with regard for the space coordination of overall dimensions and mass parameters, orientation, stabilization, resource and other parameters. t Moscow Aviation Institute, Moscow, Russia Republic
