Web27 de set. de 2024 · In this paper, we propose a thorough analysis of the design and in-flight performance for three tails. Their design and manufacturing methods are presented, with an emphasis on low weight, which is critical in ornithopters. The aerodynamics of the tails is analyzed through CFD simulations and their performance compared experimentally. Web30 de mar. de 2011 · Current understanding of the flight aerodynamics of animal tails is polarised. For example, although delta-wing theory has been used to predict tail performance in birds , more recent work , suggests this approach is not entirely valid. In bats the tail forms a continuation of the wing membrane (separated by the leg bones) …

WebLong, graduated tails, in which all but the outermost feathers are elongated, generate the same lift as normal tails (because maximum span is set by the outermost feathers and so does not WebBirds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-perform-ance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a bird's tail.
