School of Engineering Department of Mechanical and Aerospace Engineering 159 Ambular: An Emergency Response Drone Supervisor: LI Larry / MAE Student: AYDOGMUS Emre Can / AERO KAN Ho Hung / AE SWAMINATHAN Srivatsav / AE Course: UROP1100, Fall UROP1100, Fall UROP2100, Fall UROP3100, Spring Ambular, an interdisciplinary aviation project conducted in collaboration with the International Civil Aviation Organisation (ICAO), aims to develop new technology for electric vertical take-off and landing (eVTOL) vehicles. Over the next decade, such eVTOL vehicles are expected to play a leading role in the transformation of the transport sector, providing a new mode of direct transport for medical evacuations and paramedics. HKUST is spearheading the aerodynamic design and optimization of the Ambular drone. Our initial testing of the original Ambular design revealed several aerodynamic issues, the biggest of which being the negative lift generated by the fuselage and motor arms. Consequently, the current stage of the project focuses on redesigning the fuselage and optimizing the motor arm geometry. We performed extensive wind tunnel experiments using different fuselage and airfoil designs. The data were systematically collected and analyzed, and were then used to guide the development of a new generation of Ambular components. This report describes the wind tunnel testing and design optimization processes, with a focus on improving the aerodynamic efficiency of our proposed fuselage design for the Ambular drone.
