Design of a Dragonfly Inspired Lighter-than-air Vehicle

Abstract

Lighter-than-air vehicles, or blimps, are robotics platforms that possess several benefits over traditional aerial vehicles such as energy efficiency and safety in proximity to humans. While most existing blimp designs utilize traditional propellor based propulsion to generate thrust for locomotion, this project explores a bio-inspired approach to lighter-than-air vehicle design, drawing inspiration from the unique flight patterns of dragonflies. Dragonflies exhibit remarkable control, agility, and stability by independently modulating their forewings and hindwings, capabilities that guide this blimp’s mechanical design. Previous research indicates that wing-flapping mechanisms can offer greater energy efficiency and range; however, many blimps inspired by aquatic or avian creatures lack the ability to hover while carrying payloads or to execute tight maneuvers in confined spaces. This design investigates the potential increased utility and energy efficiency of dragonfly inspired flapping and articulating wings as an alternative means of lift and maneuverability.
