请继续分析、验证KF翼型。
有兴趣的模友, 可以做对比试验.
我没有亲自试过, 看过网上的介绍之后, 不打算尝试这类翼型, 感觉太浪费动力.

In 1979, P.K. Pierpont, then manager of the airfoil-research program at NASA’s Langley Research Center in Virginia, told Omni about three studies, one of them partially funded by NASA. All had come up with the same results: The Kline-Fogleman wing was found to have a poor lift-to-drag (L/D) ratio --- a standard measure of wing efficiency.
The Kline-Fogleman wing was found to have a poor lift-to-drag (L/D) ratio / KF 翼型的升阻比小得可怜.
建议若有模友有意制作又简单性能又不差的翼型, 或考虑在平板的基础上做小的改进. |
