Study of design parameters of flapping-wings
As one of the most important components of a flapping-wing micro air vehicle (FWMAV), the design of an energy-efficient flapping-wing has been a research interest recently. Research on insect flight from different perspectives has been carried out, mainly with regard to wing morphology, flapping kinematics, and unsteady aerodynamics. However, the link between the wing morphology and kinematics ...
متن کاملOutperforming hummingbirds’ load-lifting capability with a lightweight hummingbird-like flapping-wing mechanism
The stroke-cam flapping mechanism presented in this paper closely mimics the wing motion of a hovering Rufous hummingbird. It is the only lightweight hummingbird-sized flapping mechanism which generates a harmonic wing stroke with both a high flapping frequency and a large stroke amplitude. Experiments on a lightweight prototype of this stroke-cam mechanism on a 50 mm-long wing demonstrate that...
متن کاملNUMERICAL ANALYSIS OF MAVs FLAPPING WINGS IN UNSTEADY CONDITIONS
Today, Flapping Micro Aerial Vehicles (MAV) are used in many different applications. Reynolds Number for this kind of aerial vehicle is about 104 ~ 105 which shows dominancy of inertial effects in comparison of viscous effects in flow field except adjacent of the solid boundaries. Due to periodic flapping stroke, fluid flow is unsteady. In addition, these creatures have some complexities in kin...
متن کاملAerodynamic effects of flexibility in flapping wings.
Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and associated flow visualization. In contrast,...
متن کاملFlow Around Flapping Flexible Flat Plate Wings
This study investigates the unsteady flow phenomena generated from plunging wings with varying flexibility. The experiments were conducted in a wind tunnel with forward flight conditions at a chord based Reynolds number of 5300. The wings are fabricated out of homogeneous isotropic materials with values of 55 and 1702. The conditions of these experiments are matched to previous studies in a wat...
