Abstract
Addressing the challenges posed by low pressure atmosphere on Mars, this study proposes an innovative design framework for Micro Aerial Vehicles (MAVs) aimed at enhancing operational efficiency and stability on the Martian surface. Leveraging insights from Harvard University’s foundational research on bi-wing mechanisms and single actuator configurations, our research advances the conceptual and practical understanding by integrating a four-wing mechanism coupled with dual actuators. This evolution addresses the critical need for increased lift force due to Mars’ significantly lower air density compared to Earth, alongside achieving an equilibrium in torque and moment forces, thereby mitigating the limitations observed in bi-wing MAV designs under Martian conditions.
The proposed MAV framework employs advanced materials including carbon fiber for the body and wings, piezoelectric elements along with carbon and glass fibers for the actuators, and a combination of carbon fiber and polyimide film for the joints, ensuring a lightweight yet robust structure. Wing fabrication utilizes a composite of carbon fiber and polyester, optimizing for both strength and aerodynamic efficiency. The research methodology encompasses extensive simulation analyses using Ansys software, progressing from theoretical models to practical simulations, with the ultimate goal of field testing in Martian-like environments and tunnels. The design maintains the MAV’s weight under 300 milligrams, aligning with the constraints for efficient aerial performance on Mars.
The study underscores the potential benefits of deploying four-wing, dual-actuator MAVs on Mars, including enhanced exploration capabilities and support for subsequent aerospace research. However, it also acknowledges the challenges associated with micro-scale assembly and production, such as increased time and energy consumption, and higher opportunity costs compared to conventional aerospace products. Despite these challenges, the proposed MAV design represents a significant step forward in the pursuit of efficient and stable aerial exploration tools for Mars, promising a new horizon for extraterrestrial research and discovery.
