Mathematical modelling of the effect of heat fluxes from external sources on the surface of spacecraft

The solution to the problem of increasing the productivity of tow trucks and cranes on the chassis of serial cars largely depends on the solution to the issues of mastering the production of new types of heavy lifting capacity, the development and creation of progressive technological processes of maintenance and operation. Compared to a simple truck, vehicles equipped with a manipulator have a number of advantages: higher technical and economic indicators; the ability to vary the carrying capacity over a wider range; service by one driver of several transport units and others. The efficiency of using such units is mainly determined by the totality of their operational properties, which require rational management at the stages of design, production and operation. There are many types of lifting mechanisms for loading units, the most common of which are structures in the form of a telescopic boom and in the form of a combined loading device. The aim of this work is to create and parametrize the invariant structure of a telescopic boom in such a way that, when changing its parameters, it would be possible to obtain an arrow of any kind. The presented consideration shows that the use of such machines and assemblies is a wide area, in the study of which it is necessary to apply many branches of modern natural science and technology. There is no doubt that both the growth of research in this area and an increase in the volume of practical applications of objects of this type will continue.

The article is devoted to the study of parametric properties of multilayer heat-reflecting screens. Special attention is paid to the parameters of shielding and heat flow absorption. The study, its numerical and analytical techniques ensure that the fuzzy input situation is taken into account. The fuzziness is generated by the variance of both the values of geometric parameters and the actual values of structural elements. The proposed analytical and numerical research techniques are applicable in a wide range of productions of thermal protective products – for the energy industry, radio electronics, aerospace instrumentation, production of building structural elements. The theory of fuzzy sets is actively applied in terms of the heuristic principle of expansion. It is the basis for regular versions of the presented models. The underlying calculations are based on fuzzy numbers that represent exogenous parameters.
