Feasibility Study of an Aerial Lifting Device Using Aerodynamic Drag for Ascent

Flying typically involves thrust or buoyancy in order to climb in altitude while trying to minimize drag. These setups can result in large, energy-exhaustive mechanisms. This paper presents a novel alternative to the traditional approaches of flying by utilizing aerodynamic drag. Drag can be used as an opposing force needed to lift a load off of the ground. The concept is verified through a series of experiments in which a balloon is used to lift a parachute to a desired height, and then an actuator with a load on the ground retracts a rope connected to the parachute. Aerodynamic drag is translated into a lifting force. This cost-effective, energy efficient, and modular method can increase the mobility of robots, delivery systems etc.
