Dynamic analysis of wing deployment of high altitude balloon launched small size folding-wing UAV 1

Abstract

The batch launch of small folding-wing UAVs by high altitude balloon at high altitude is a new technology in recent years. The wing deployment process at 20km altitude is analyzed, and mathematical model of the wing delivery is established. Using the multibody dynamics analysis software ADAMS simulate the wing deployment process in order to verify the correctness of the model established. Then, the impact of the wing with final velocity on the fuselage is analyzed, and an elastic locking mechanism is designed to reduce the impact. The analysis process provides a certain reference for the task design of balloon-UAVs and the folding mechanism analysis.
