Once a maple seed lands, the wing helps it stand upright between blades of grass or other foliage. The images the team obtained showed that a swirling maple seed generates a tornado-like vortex that sits atop the front leading edge as the "helicopter" spins slowly to the ground.

Like most scientific papers it’s pretty jargon and greek symbol heavy. Rev. One explanation of its spinning motion is the auto-rotational effect. During autorotation, the governing aerodynamics allow the seed to slow down its vertical velocity to a certain extent, rendering it more susceptible to effective wind dispersal. The primary paper I referenced when trying to determine how best to replicate the maple seed was “The kinematics of falling maple seeds and the initial transition to a helical motion” by Kapil Varshney, Song Chang, and Z Jane Wang. Once pressed into the soil – whether by a passing foot, the weight of snow or something else – the wings break away so that the seed can germinate more easily. The Aerodynamics of a Falling Maple Seed Task for a project or thesis Background The maple seed (Acer pseudoplatanus) enters an autorotation after it is released from its stem, connecting it to the maple tree.

Flight of a falling maple seed Injae Lee and Haecheon Choi Phys. Request PDF | Falling Maple Seed: The mechanism for its spin | A maple seed falls in a characteristic downward spiral. The upright seeds have a better chance of embedding themselves into the soil below. This type of issue is often present in commercial fruit tree orchards and is termed “alternate bearing” with some years a light crop of fruit and others being a heavy crop year.
