Design of folded wing mechanism for Unmanned Aerial Vehicle (UAV)

Unmanned Aerial Vehicles (UAVs) have been widely used both in military and civil all across the world in recent year. Many types of UAV technologies have been developed to answer the global needs, such as for aerial mapping, aerial surveillance, atmospheric sensing, payload delivering, and for war missions. Most of the UAV are open wing mechanism that causes problem to transport UAVs to other places due to require large space.The main aim of this project is design of folded wing mechanism for small-UAV (<15 kg) and minimize storing and shipping space required. The paper gives review of design of folded wing mechanism for small-UAV (<15 kg) and motion analysis results for mechanism. Role of mechanism as to fold the wings in idle position manually and automatically open the wings when released from launcher and hold the wings by spring force while travelling.Both Modelling and Motion analysis are done using SOLIDWORKS software. An evaluation is carried out between different concepts and solutions to determine the final concept feasibility. Required spring rate, time required to open wing automatically and Contact force generated by wing and mechanism anima-tion are calculated from motion analysis.Copyright (c) 2022 Elsevier Ltd.
