The Study of Flying Seeds

Koki MIZUI Assei SANZEN

Motivation We chose this topic because we are interested in flying things.

Now, air planes fly in the sky but they consume a large amount of fuel.

The seeds of Alsomitra macrocarpa have wings and they can fly very far.

They don't need their own force to move.

About Alsomitra Macrocarpa big fruit thin feather

Experiment We prepared some models from styrofoam.

We named them: Ks, Ms, and As (s means styrofoam) We dropped each model 10 times from 2.45m high.

How to drop

Type ”a” Falling Large ; Flying Small ; Falling

Type ”b” Falling

Type ”c” Falling

Type ”d” Falling

Type ”E” Flying

Type ”F” Flying

Type ”G” Flying

Type ”h” Falling

Type ” j ”Falling

Result 1 N; 7% h; 18% G; 14% F; 23% c; 1% d; 3% E, 34% Large ; Flying Small ; Falling G h j N a b c d E F

Result 2 Ks a b h j n f g c d e 0 0.0% 0 0.0% 5 2.0% 10 4.0% 96 38.4% 66 26.4% 20 8.0% 42 16.8% 0 0.0% 11 4.4% 250 100% Ms a b h j n f g c d e 0 0.0% 0 0.0% 0 0.0% 0 0.0% 7 11.7% 5 8.3% 28 46.7% 8 13.3% 0 0.0% 12 20.0% 60 100% h j n f g c d e As a b 0 0.0% 0 0.0% 0 0.0% 0 0.0% 13 43.3% 6 20.0% 1 3.3% 10 33.3% 0 0.0% 0 0.0% 30 100%

Consideration ① We can classify these models under two types.

Model K & A → Model M → Straight flying Type “ Wave flying Type “

g

e

” ” ② We should consider how to keep these models ; if they change their shape , their way of flying will change.

Hopes ① We want to find what changes the way of flying between Type” e ” and Type” g ”.

② We want to find the relationship between the biological and physical mechanisms of these seeds.

Thank you for listening.
