title = "Lift and drag of flapping membrane wings at high angles of attack",
abstract = "An experimental study was undertaken to assess the aerodynamic benefits of flapping in forward flight at various Reynolds numbers and flapping frequencies. The test article is a commercially available ornithopter whose flapping wing is a flexible membrane. Analysis has focused on the time-averaged aerodynamic performance (i.e. mean lift and thrust/drag). Results to date reveal a consistent trend in the variation of the thrust produced with changes in flapping frequency and angle of attack. These results are presented in terms of classical aircraft performance parameters, e.g. cycle-averaged lift and drag coefficients. The average effect of the flexible flapping wing on vehicle performance is thus expressed in familiar terms, parametrized by the flapping frequency.",
