dc.description.abstract | In the quickly expanding field of Industrial Multirotor Drones, one of the main limitations is flight time of current multirotor systems. A method of increasing the flight time is to improve the efficiency of the aircraft design. One possibility for increasing efficiency is synergetic design. Synergetic design is a principal where two or more systems are designed to interact to increase the efficiency of the complete system. In the wind turbine industry, synergetic spacing has been used for increasing the efficiency of vertical axis wind turbines by utilizing staggering. Staggered horizontal axis wind farms have been shown to increase the efficiency by as much as 5% over aligned. These methods even more effective for vertical axis wind turbines due to their specific wake pattern. This project reports the results of synergetic efficiencies of driven propellers in various configurations utilizing a test stand. The design requirements for this stand included minimizing outside interference, the ability to test a wide variety of propellers, and have a built-in measurement system for the required calculations. The measurements that were required included the power consumption, rotational speed, thrust output, and spacing of the motors. The test stand also features a custom electronic system for running the systems. The objectives that were completed by the electrical system included driving the motors, setting the desired speed, and measuring the rotations per minute. Data collection methods and raw data gathered are described, discussed, and compared to theoretical maximum efficiency of the propulsion system. | en_US |
