Abstract

The work aims to review and analyze the research progress of key technologies in the air landing phase of parachute-free airdrops, to further promote the systematic development of parachute-free airdrop technology, and provide a theoretical basis for improving the precision and safety of parachute-free airdrops in China. The research was conducted by systematically sorting out the current development status of parachute-free airdrop technology, and focusing on analyzing the current research status of air-landing phase technology and then predicting its development trend. Research indicated that unmanned aerial delivery systems achieved significant progress in landing point accuracy and terminal velocity control during the aerial descent phase. However, this technological system still faced systemic bottlenecks such as adaptability to high-dynamic turbulent environments, balancing structural lightweighting with reliability, and multi-body collaborative decision-making. These constraints limited its scalable and reliable application in complex missions. In conclusion, with the development of science and technology, the development and utilization of parachute-free airdrop air landing stage technology based on the aerodynamic-based parachute-free airdrop method and the gliding UAV technology will continue to be improved and perfected, providing more choice space for air delivery and landing.
