The purpose of the work is creation scientific bases for the development of modern materials and constructions of aircraft by improving the quality in the manufacture of large-sized power construction elements, pipelines of carrier-rockets, increasing the complex of technological and physical-mechanical properties of multi-component alloys, creating new composite materials, improving the quality of welded joints constructions of high-strength alloys.Research Methods are the next: mathematical modeling; graphical-analytical method, finite element method (calculations and practical real experiments); physical-mechanical, X-ray and microstructural researches. Scientific bases have been created in areas related to: development of optimal technologies for the modification of multi-component melt alloys based on aluminum and nickel with dispersed refractory compositions in order to increase their physical and mechanical properties, solidifying composites using selective infra-red heating; manufacture of composite materials for the protection of spacecraft on-board equipment from the influence of cosmic radiation; development and implementation of thermally-shape-dimension stable composite structures of space designation; development the technologies of electron beam welding of thick-walled cylindrical parts of high-strength titanium alloys; determination of the interdependence of the hollow cathode welding mode parameters with the geometric characteristics of the melting zone; development of diffusion welding technology of titanium alloy with stainless steel on covered surfaces; with increasing accuracy of ductile geometric sizes when assembling construction elements of rocket-space aircraft products thanks to rational modes of power elements manufacturing.
