Journal ArticleDOI
A quasi-steady aerodynamic model for flapping flight with improved adaptability.
TL;DR: An improved quasi-steady aerodynamic model for flapping wings in hover is developed to yield rapid predictions of lift generation and efficiency during the design phase of flapping wing micro air vehicles and has the advantage of being applicable over a wider range of flow conditions without prior tuning or calibration.
Journal ArticleDOI
Aspect ratio effects on revolving wings with Rossby number consideration
TL;DR: By isolating the effect of Ro, it is found that higher AR produces higher mean lift coefficient until it plateaus at a sufficiently high AR, which is consistent with conventional fixed wing aerodynamics.
Journal ArticleDOI
Vortex-induced vibration wind energy harvesting by piezoelectric MEMS device in formation.
TL;DR: A silicon chip integrated microelectromechanical (MEMS) wind energy harvester, based on the vortex-induced vibration (VIV) concept, has been designed, fabricated, and tested as a proof-of-concept demonstration and demonstrates a potential means of powering small off-grid sensors in a cost-effective manner due to the easy integration of the energy harvey and sensor on the same silicon chip.
Journal ArticleDOI
Ground effect on the aerodynamics of three-dimensional hovering wings.
TL;DR: The present study shows that changes in wing planform have insignificant influence on the overall trend of ground effect except for a parallel shift in force magnitude, which is caused mainly by the difference in aspect ratio and leading edge pivot point.
Journal ArticleDOI
Aerodynamic effects of elevating motion on hovering rigid hawkmothlike wings
TL;DR: In this article, the effects of elevating motion to lift generation and vortex structure development when rigid wings are subjected to three-dimensional simple harmonic motion and hovering hawkmoth flapping motion.
