The metabolic cost of emulated aerodynamic drag forces in marathon running.
Journal of applied physiology, 2022The benefits of drafting for elite marathon runners are intuitive, but the quantitative energetic and time savings are still unclear due to the different methods used for converting aerodynamic drag force reductions to gross metabolic power savings ...

Enabling Dynamic Behaviors With Aerodynamic Drag in Lightweight Tails
IEEE Transactions on robotics, 2021Many agile legged animals employ lightweight, furry tails to regulate orientation during running, leaping, and turning. Most robots attempting the same tasks either lack a tail or employ one with high inertia, which can induce impractical payload and ...

Cooperative control for multiple quadrotors under position deviations and aerodynamic drag
, 2021In this paper, cooperative control is investigated for leader–follower multiple quadrotors under position deviations and aerodynamic drag. The leader–follower multiple quadrotors are modeled to cooperative subsystems and position subsystems.

Aerodynamic phenomena and drag of a maglev train running dynamically in a vacuum tube
The Physics of Fluids, 2022A maglev train can run at supersonic speed in a vacuum tube, and its transient state makes the airflow around it more complex. Therefore, to assist vacuum tube train studies, a flying model test platform is under construction. Using a model flying at the

Aerodynamic drag optimization of a high-speed train
, 2020This paper considers the optimization of the nose shape of a high-speed train to minimize the drag coefficient in zero-yaw-angle conditions. The optimization is performed using genetic algorithms (GA) and is based on the Aerodynamic Train Model (ATM) as ...
