The purpose of the study was to analyze the scientific and technological aspects of the development and production of modern rotary piston engines (MRPE) for unmanned aerial vehicles (UAVs) of leading foreign countries and to develop recommendations on the priorities of their development in the Russian Federation. In the course of the study, a significant amount of information on the main, most significant achievements in the creation of aviation MRPE abroad was summarized, analyzed and systematized.
Based on the results of the analysis, the main factors and trends are shown, a number of specific areas most typical for research and development, determining the development of aviation MRPE in the most developed countries, recommendations for the development and production of MRPE in Russia are given. Due to the severity of the problem of import substitution of foreign MRPE for UAVs in the Russian Federation, the results of the study shown in the article are relevant, can be used by interested specialists in solving the problems of development, production and use of MRPE in the interests of defense and security of Russia
