Annotation: The article outlines the prospects, possibilities, and directions for the space rocket applications of aluminumscandium alloys in Ukraine. It also analyzes the potential of Ukraine as a supplier of aluminum-scandium alloys. The relevance and the scientifi c novelty of this study are determined by the need to fi nd new materials to replace traditional supplies, considering the aggravation of geopolitical confrontation (trade wars) between the PRC, USA, EU, Russian Federation, and other world powers in the markets of strategic raw materials. As part of the search for alternative materials and sources of import for the manufacturing of space rocket technologies, this paper studies the possibilities of using aluminum alloys with enhanced properties, namely: Al–Mg, Al–Li, Al–Cu–Li, Al–Si–Mg, Al–Sc, and Al–Mg–Sc alloys. The paper demonstrates that the physical, mechanical, and chemical properties of aluminum-scandium and aluminum-magnesium-scandium alloys fi t the operating conditions of space rocket technologies. Moreover, these alloys have many advantages and allow for the enhancement of principal technical parameters for space rocket technologies, such as structural perfection (reduction of the mass of structures, high manufacturing accuracy due to the fi ne grain size of alloys), reliability of operation under severe conditions (high strength and resistance to vibration, heat, and corrosion), and the possibility of repeated use (heat resistance and durability of alloys). The manufacturing of parts from these alloys does not diff er from traditional production processes. Aluminum-scandium alloys are easy to weld, press, and machine by cutting. The paper corroborates that Ukraine holds the potential to revive its production of aluminum-scandium alloys, as it possesses a functioning research base and professionals. Ukraine’s mineral and feedstock base for scandium enables the country to satisfy any needs of the space rocket industry. Until 1995, Ukraine operated a plant producing scandium-containing alloys from Ukrainian raw materials. The resumption of production requires investment and political will.

Key words: aluminum-scandium alloys, space rocket technologies, market research, aluminum alloy manufacturers, price indicators

Annotation: The article is devoted to optimization of a trajectory of the antiaircraft guided missile performed in design phase. The review of existing solutions on this issue confirmed the topicality of the problem. The analytical solution cannot be obtained, therefore, according to modern tendencies, optimization by numerical method of original development was performed. The basis of the method is two-level optimization which is carried out, in turn, by two different numerical methods and for two different criteria functions. At the top level, by method of random search and as a variant, by method of coordinate descent, the search was carried out for a fixed set of intermediate for the specified flight range trajectory points which co-ordinates in aggregate provide the necessary optimum. At the bottom level, for each pair of consecutive intermediate points, the boundary problem of falling into distant point by one-dimensional optimization was solved. The coordinate descent method was used for search for the simplified flight program. As optimization criteria for top level, minimum flight time or maximum final speed, for bottom  terminal criterion were used. The control program selected the angle of attack program. As a result, the optimum and suboptimum (additionally ensuring minimum calculation time) trajectories and flight programs to maximum range and different altitudes were obtained. The analysis of results showed practical proximity of trajectories of minimum flight time and maximum final speed.

Key words: anti-aircraft missile, optimization, angle of attack program, trajectory
