Enclosure enhancement of flight performance
MetadataShow full item record
We use a potential flow solver to investigate the aerodynamic aspects of flapping flights in enclosed spaces. The enclosure effects are simulated by the method of images. Our study complements previous aerodynamic analyses which considered only the near-ground flight. The present results show that flying in the proximity of an enclosure affects the aerodynamic performance of flapping wings in terms of lift and thrust generation and power consumption. It leads to higher flight efficiency and more than 5% increase of the generation of lift and thrust. © 2014 The Chinese Society of Theoretical and Applied Mechanics.

Failure to launch? The influence of limb autotomy on the escape behavior of a semiaquatic grasshopper Paroxya atlantica (Acrididae)Bateman, Bill; Fleming, P. (2011)Autotomy is an extreme escape tactic where an animal sheds an appendage to escape predation. Many species alter their behaviour postautotomy to compensate for this loss. We examined the escape behavior in the field of a ...
