Other claims from this paper (7)
- Association Seeds with more clipped wings were more likely to fall into unsteady rotation even in free fall.
- Mechanism Seeds with clipped wings have a larger pressure difference between upper and lower wing surfaces, which contributes to larger lift.
- Observation A stable separated vortex ring dominates the stable autorotation of tristellateia seeds.
- Observation An unstable separated vortex emerges on tristellateia seeds with less wings, making stable flight difficult to achieve.
- Observation Three kinds of vortex systems occur on rotating tristellateia seeds.
- Observation Seeds with different clipped wings present various vortex morphology and structure.
- Association Growth rate of descending velocity and spinning rate of tristellateia seeds are related to wing number.
