Research review of the autonomous aerial refueling technology

It is one of the research hotspots in the field of aviation at home and abroad that autonomous aerial refueling can realize a erial refueling of unmanned aerial vehicles and improve the efficiency of aerial refueling of manned aircraft. Due to the disturbance of atmospheric environment and the aerodynamic coupling disturbance of refueling formation, the dynamic characteristics of autonomous air-loading process are complex and difficult to control. Currently, according to the decades of critical research on air refueling abroad, related technologies have been gradually applied to engineering practice. A series of research work on traceability theory has been carried out in this field in China, but it has not yet formed a complete closed-loop research. This paper aims to analyze the technical requirements, constraints and key technologies of self-contained air-to-air refueling by summarizing the research results at home and abroad, and puts forward the following research direction for the domestic research.
