Boundary effects such as the ground and ceiling effect, which provide increased thrust and decreased power consumption, are vital for the future of efficient flight as they are important for performance and safety. In this paper, the impact of rotor--rotor interactions with varying rotor hub distances on each rotor's near-boundary performance (thrust and power) was investigated. The results show that as the rotors decrease in separation distance from each other, the near-boundary effects increase, providing performance benefits for the vehicle. However, the opposite happens as the rotor hub distances increase; the performance near the ground degrades. The current results can be used for future understanding of multirotor interactions near boundaries, leading to better vehicle design and potentially getting increased performance benefits in near-boundary flight for multirotor vehicles.}, booktitle={AIAA AVIATION 2023 Forum}, publisher={American Institute of Aeronautics and Astronautics}, author={Carter, Darius and Rauleder, Juergen}, year={2023}, month={Jun} }

Search and rescue and product delivery (two key MAV applications) occur in tight, confined spaces filled with complex obstacles. Our current understanding of how micro-quadrotors interact with boundaries is based primarily on helicopter models, which were designed for high-Reynolds-number single-rotor flows. To test how well existing near-boundary models apply to micro-quadrotors, the thrust forces and wakes of a micro-quadrotor near a ground, ceiling, and sidewall were measured. It is found that micro-quadrotors (like their larger counterparts) experience a large boost in lift near the ground/ceiling and a slight drop in lift near the sidewall. Particle image velocimetry is used to quantify the velocity around the rotors and evaluate the assumptions made by existing ground and ceiling models. Complex boundary-layer interactions were observed at low altitudes, especially when the quadrotor was tilted relative to the ground. Reduced-order modeling was also used to explore the safety implications of near ground/ceiling flight. Tradeoffs between safety and efficiency that are sensitive to the ground/ceiling models were discovered, highlighting the need for precise near-boundary models. The results of this study therefore offer guidance for near-boundary model-driven controllers that could improve situational awareness and sensorless landings.}, number={4}, journal={AIAA Journal}, publisher={American Institute of Aeronautics and Astronautics (AIAA)}, author={Carter, Darius J. and Bouchard, Lauren and Quinn, Daniel B.}, year={2021}, month={Apr}, pages={1398–1405} }

Shrinking these vehicles is desirable since agility increases. However, it entails smaller power sources and hence less flight time. Adding sensors on these systems also implies more energy consumption due to both the added weight and the supplied energy to the sensors. In this work, we build a framework to leverage the flow dynamic effects near surfaces to recognize grounds and ceilings during operations and to plan a trajectory while minimizing energy consumption. Our proposed framework leverages data from real experiments to model the behavior of the system near surfaces and graph theoretical approaches for energy efficient motion planning. As a result, this study indicates that i) we can detect surfaces during operations without the need of extra onboard sensors and ii) we can minimize energy consumption up to 15% when the system can fly near ground or ceiling surfaces. The proposed framework is validated with experimental results on a quadrotor UAV.}, booktitle={2019 International Conference on Unmanned Aircraft Systems (ICUAS)}, publisher={IEEE}, author={Gao, Shijie and Franco, Carmelo Di and Carter, Darius and Quinn, Daniel and Bezzo, Nicola}, year={2019}, month={Jun} }
