| Abstract | Low-order methods are well developed for the prediction of the aerodynamic characteristics of a given wing. The basic wing planform characteristics, such as its taper ratio, span and surface, are usually directly defined by the lift and structural requirements. To satisfy the imposed spanloadings, a reverse design process must be used in order to find the geometric twist required. Optimization techniques can be used but they require some expertise. It would be desirable to obtain this geometric twist through the same tools used for the direct design. This paper presents three methods to recover the geometric twist on tapered straight wings without and with sweep angles. Low-order methods currently employed for direct design are used. Their computational times are thus or the order of one minute on a standard laptop. Two methods use open-source software while the third one is strictly analytical and not applicable to swept wings. Extensions needed to predict the twist are presented in detail. Results on unswept and swept tapered wings demonstrate that the methods can predict the geometric twist, although some tuning is required. |
