摘要：

A wind tunnel experiment was conducted to determine the effects of Gurney flap modifications on the aerodynamic characteristics of several two- and three-dimensional wings. The lift and aerodynamic efficiency results obtained from this experiment were compared with those obtained from a previous experiment. Both experiments agree on the overall effect of Gurney flaps on the lift characteristics of wings. However, it was observed that the larger solid flaps provide little additional lift benefit while negatively affecting the drag.
