All you need is time to generalise the Goman-Khrabrov dynamic stall model

Karen Ann J Mulleners, Fatma Ayancik Cinoglu

Dynamic stall on airfoils negatively impacts their aerodynamic performance and can lead to structural damage. Accurate prediction and modelling of the dynamic stall loads are crucial for a more robust design of wings and blades that operate under unsteady ...

Experimental investigation and analytical modelling of active yaw control for wind farm power optimization

Fernando Porté Agel, Haohua Zong

In this study, the physics and effectiveness of active yaw control under various wind conditions are investigated systematically, based on wind tunnel experiments and a new analytical wind farm model. The power and wake velocity measurements of a three-row ...

Comparative dynamic flight stability of insect-inspired flapping-wing micro air vehicles in hover: Longitudinal and lateral motions

Hoang Vu Phan, Khanh Nguyen

In this paper, we compare the characteristics of hovering stability for two insect-inspired flapping-wing micro air vehicles (FW-MAVs) with different strategies to generate control moments for the longitudinal and lateral attitude controls. The two robots ...

Passive Perching with Energy Storage for Winged Aerial Robots

Dario Floreano, Yegor Piskarev, William John Stewart, Luca Guarino

Perching in unmanned aerial vehicles (UAVs) offers the possibility of extending the range of aerial robots beyond the limits of their batteries. It has been a topic of intense study for multirotor UAVs. Perching in winged UAVs is harder because a kinetic e ...

Phenomenology and scaling of optimal flapping wing kinematics

Karen Ann J Mulleners, Alexander Gehrke

Biological flapping wing fliers operate efficiently and robustly in a wide range of flight conditions and are a great source of inspiration to engineers. The unsteady aerodynamics of flapping wing flight are dominated by large-scale vortical structures tha ...

Lidar measurements of yawed-wind-turbine wakes: characterization and validation of analytical models

Fernando Porté Agel, Peter Andreas Brugger, Haohua Zong

Wake measurements of a scanning Doppler lidar mounted on the nacelle of a full-scale wind turbine during a wake-steering experiment were used for the characterization of the wake flow, the evaluation of the wake-steering set-up, and the validation of analy ...

Ori-Pixel, a Multi-DoFs Origami Pixel for Modular Reconfigurable Surfaces

Jamie Paik, Stefano Mintchev, Marco Salerno

Reconfigurable surfaces using robotic pixels can produce discretize 3D contours, shapes and motion patterns. In existing devices, the rendering resolution and richness of shapes and patterns are limited by the use of linear pixels that only produce single ...

Wind farm power optimization via yaw angle control: A wind tunnel study

Fernando Porté Agel, Majid Bastankhah

Yaw angle control is known nowadays as a promising and effective technique to mitigate wake effects in wind farms. In this paper, we perform wind tunnel experiments to study the performance of a model wind farm with five turbine rows under a wide variety o ...
