An application of Falkner's surface-loading method to predictions of hinge-moment parameters for swept-back wings
Year: 1948
Abstract: Application of the Falkner lifting-surface-theory method to the prediction of hinge-moment and, incidentally, lift parameters for swept-back plan forms has been made in a attempt to develop an analogue to the existing lifting-surface-theory procedure for prediction of these parameters on unswept plan forms. For the two specific swept-back plan forms investigated the hinge-moment predictions based on the Falkner method were not in good agreement with experimental values. The discrepancies between the predicted and the experimental results probably are due to the effects of fluid viscosity which were not included in the Falkner method as applied herein.
