Paper Helicopter Experiment

Set factors

A: Wing length WL (cm) Range 5–15 cm

B: Wing width WW (cm) Range 2–6 cm

C: Body length BL (cm) Range 3–10 cm

D: Body width BW (cm) Range 1–4 cm

Drop height (m) Constant, not a factor

Experiment mode

Deterministic Stochastic

Same factors always produce the same result.

Fixed constants used in the model

Paper 80 g/m² (A4) + paper clip 0.5 g.
Rotor acts as a disc of area π·WL²; Cd = 0.8 × (WW / 4 cm)^0.8.
Blades need ~0.3 s to spin up after release.
Gravity + quadratic air drag (½ρCdAv²), integrated with RK4 every 0.001 s.
