我引用某国RC直升机网页 John Salt 关于自旋的一段话。原文如下:
”If you had fixed pitch or kept the rotor blades at a positive pitch angle, they would soon stall and stop rotating. Yup - the helicopter has now become an expensive rock. This is why autorotations rely on collective pitch. ”
收到这样一段文字的回复
“航模直升机由于自重相对低,大多数比较适合使用负螺距,并不意味着负螺距是必然的。这句话也没有任何理论分析,作为依据不足以说明问题。事实上正螺距自旋是存在的,并且航模也能实现,只是飞行员技术不成熟的话会很容易造成失速炸机。”
请问这里哪位高手能用正螺距自旋不掉转?
