Resumo

The objective of this study was to design and optimize a flying ambulance that could quickly pickup and transport patients from emergency locations to the nearest hospitals. The concept was to have the ambulance carry a paramedic weighing less than 200 pounds to the scene. Once at the scene, the paramedic would stabilize the patient and load him/her into the ambulance. Once the patient was onboard, the ambulance would then be remotely piloted back to the hospital to receive treatment. The aerial vehicle is designed to be able to land in a single lane without needing the larger landing area required for a helicopter.
SolidWorks CAD, SolidWorks Simulation and SolidWorks Flow Simulation software were used to model the propeller and frame, and evaluate these designs through structural, fatigue and flow analyses. Comparison of the flow analysis results of rotating rotor systems with experimental results in literature was successfully performed. For the propeller, three different configurations were run; single propeller, stacked propellers, and across-frame propellers. The most conservative result was chosen, giving necessary thrust per propeller. Structural analyses were run on the propeller and frame to determine factors of safety. Fatigue analyses were then performed on them to determine lifespans. The drag coefficient was determined by running flow analyses on the frame and shell assembly. This coefficient was then used to determine the maximum velocity of the vehicle to be 216 mph. This vehicle bridges the gap in capabilities of a conventional ambulance and a medevac helicopter.
