蜻蜓与飞机说到仿生学,人们比较熟悉的一个例子,就是蜻蜓与直升飞机。蜻蜓通过翅膀振动可产生不同于周围大气的局部不稳定气流,并利用气流产生的涡流来使自己上升。蜻蜓能在很小的推力下翱翔,不但可向前飞行,还能向后和向左右两侧飞行,其向前飞行速度可达每小时72千米。蜻蜓的飞行行为简单,仅靠两对翅膀不停地拍打就能实现飞行自如。受此启发,人类发明 Dragonfly and aircraft Speaking of bionics, one of the more familiar examples is the dragonfly and the helicopter. Dragonfly vibration through the wings can produce a local unstable air flow different from the surrounding atmosphere, and the use of eddy currents to make their own rise. Dragonfly can soar with a small lift, not only can fly forward, but also fly backwards and to the left and right, its forward flight speed of up to 72 km per hour. Dragonfly flight behavior is simple, just by two pairs of wings keep flapping can fly freely. Inspired by this, human invention
