    • 家园 德国那个FL282没有尾桨怎么抵消旋翼的扭矩?
      • 家园 那是共轴反转双桨,上下旋翼比较靠近而已
        • 家园 看图不像共轴的

          好像是交错式的双反桨

          就像卡曼HH-43这种:

          • 家园 可能你是对的

            资料上说是共轴反转双桨,看看也不像,等有更多更清晰的大图再说吧,存疑。

            • 家园 wikipedia真好

              http://en.wikipedia.org/wiki/Flettner_Fl_282

              The Flettner Fl 282 Kolibri is a single-seat open cockpit intermeshing-rotor helicopter, or synchropter, produced by Anton Flettner of Germany.

              The Kolibri ("hummingbird") was one of the first helicopters to be used in warfare. During World War II, Nazi Germany tested the craft in the Mediterranean theatre. Plans to build thousands of Kolibris were abandoned after the Flettner factories were bombed by the Allies. Only three of these helicopters survived the war; the rest were destroyed to prevent capture.

              • 家园 正准备今天查一下呢,老兄走到前头了

                看来我原先的资料有误,多谢指正。

    • 家园 据说最早用直升机作战的是英国人?

      好像是苏伊士运河危机时的operation musketeer,史上第一次采用直升机空降部队
