Design and Development of Autonomous Coaxial Rotor Micro Air Vehicle

Abhishek Abhishek

Abstract


This paper discusses the preliminary investigations towards the design and development of coaxial Micro Air Vehicles. The paper is divided in to two parts. First part describes the experimental investigation of the aerodynamics of the circular arc airfoil with 6% camber to understand the role of parameters like blade radius, chord length, shape of leading edge and aspect ratio to estimate the best candidate for a coaxial MAV design. Second part describes the manufacturing of various structural components of the MAV and the integration of various sub-systems including a few commercial-off-the-shelf parts in to a fully functional coaxial rotary wing MAVs. The experiments on the rotor blades were performed on a hover test stand built for this purpose. A six component load cell was used to measure thrust and power for various blades, a Hall’s effect sensor was used to sense the rotor rpm. The MAVs built have successfully flight tested for both indoor as well as outdoor flights.
