Morphological synthesis method of search for promising technicalsystem

The work studies the application of the morphological (structural) synthesis method of search for the new technical approaches. The method is based on the application of the theory of system, morphological and cluster analysis, methods of mathematics simulation and calculation experiments made by computer. The work shows how this method is used to synthesize the landing spacecrafts, hypersonic spacecrafts and medical equipment and gives the comparison of the present and synthesized technical systems (TS). The conclusion is that this method increases the degree of the validity decision made and broadens the number of possible variants which allows an increase in the quality (technical level) of the TS under development. The work also points out that the method allows the system to search for promising inventions to solve the problems of prognostication and to single out the trends of TS evolution. It also allows the system to single out these systems which are able to respond flexibly to the changing external conditions with the lowest expense, and therefore, increases the compatibility of the chosen TS     

To the problem of spectrum investigation with an on-board analyser VAR

The spectrum analysis of low frequency processes on board the satellite becomes inevitable in connection with the investigation of the thin structure of specific areas in magnetosphere, main shock wave and solar wind. The necessity to perform the analysis in a rather short period of time is a peculiarity of the thin structure investigation procedure. The evaluation of drawbacks and advantages of various spectral analysis techniques shows that the discrete Fourier transform (DFT) method is most efficient for the case. It enables us to perform a parallel analysis of several processes in different frequency subranges. The amplitudes and frequencies of polyharmonic processes and spectral power of low frequency random processes are determined. The technique described in this paper has been developed at the Institute for Physics and Mechanics of the Ukr. S.S.R. Academy of Sciences to determine the amplitudes and frequencies of the polyharmonic processes components. The analyser VAR designed at the Institute is supposed to be utilized in international cosmic tests.
