Abstract:

Based on testing results of aerodynamic forces and pressures from a wind tunnel, the longitudinal aerodynamics characteristics of a forward swept wing are discussed in this paper. The results are also compared with the data of an associated aft swept wing. Measures of improving the inboard flowfield of a forward swept wing are also investigated, and the results are discussed. Under a low speed situation, an appropriate sweptback of the root section can improve the flow consequently obtaining higher aerodynamic performances.
