Towards bio-inspiration, development, and manufacturing of a flapping-wing micro air vehicle
(2020-09-01)
Throughout the last decade, there has been an increased demand for intricate flapping-wing drones with different capabilities than larger drones. The design of flapping-wing drones is focused on endurance and stability, ...
On the aerodynamic analysis and conceptual design of bioinspired multi-flapping-wing drones
(2021-09-01)
Many research studies have investigated the characteristics of bird flights as a source of bioinspiration for the design of flapping-wing micro air vehicles. However, to the best of the authors’ knowledge, no drone design ...
Determination of the instantaneous forces on flapping wings from a localized fluid velocity field
(American Institute of Physics, 2011-11)
Expressions are derived to relate the instantaneous pressure force on a flapping wing to the velocity field on a plane at the trailing edge and on a highly localized region around and near the wing, valid when the vortex ...
Modified unsteady vortex-lattice method to study flapping wings in hover flight
(Amer Inst Aeronaut Astronaut, 2013-09)
A numerical-simulation tool is developed that is well suited for modeling the unsteady nonlinear aerodynamics of flying insects and small birds as well as biologically inspired flapping-wing micro air vehicles. The present ...
Computational dynamics of flapping wings in hover flight: A co-simulation strategy
(Amer Inst Aeronaut Astronaut, 2017-06)
A co-simulation strategy for modeling the unsteady dynamics of flying insects and small birds as well as biologically inspired flapping-wing micro-air-vehicles is developed in this work. In particular, the dynamic system ...
Role of active morphing in the aerodynamic performance of flapping wings in formation flight
(2021-09-01)
Migratory birds have the ability to save energy during flight by arranging themselves in a V-formation. This arrangement enables an increase in the overall efficiency of the group because the wake vortices shed by each of ...
A novel multi-flapping-wing air vehicle: conceptual design and aerodynamic analysis
(2022-01-01)
Many designs for flapping-wing vehicles have been inspired from birds given their outstanding flight capabilities. Birds have been observed to obtain aerodynamic benefits by flying together in V-formation, a unique feature ...
Dynamics of micro-air-vehicles with flapping wings: A multibody system approach
(Institute of Electrical and Electronics Engineers, 2013)
Biomimicry and aerodynamic performance of multi-flapping wing drones
(2021-01-01)
Certain birds have been noted to fly in V-formation, an arrangement which may be used to conserve energy when migrating over long distances without stopping and feeding. The use of such grouping arrangement and organized ...
