Presets

Angle of attack (°)

Aspect ratio

Lift rises almost linearly with angle of attack — until the airflow separates and the wing stalls, losing lift sharply. Drag has a fixed part plus induced drag that grows with lift squared and shrinks with aspect ratio. The lift-to-drag ratio, peaking at a modest angle, is the single number that governs a wing's efficiency.

Governing equation

C_{D} = C_{D 0} + \frac{C _{L}^{2}}{π A R e} = 0.020 + \frac{0.5 3 ^{2}}{π \cdot 8 \cdot 0.85} = 0.033

Reading this result: Pre-stall: lift rises almost linearly with angle of attack at 6°, well below the ~15° stall angle. Adding camber would lift the entire curve higher.

floating equilibrium by density

Controls

An object floats with exactly the fraction ρ_object/ρ_fluid submerged. Denser than the fluid? It sinks. This is Archimedes' principle, live.

Governing equation

\frac{V _{s u b}}{V} = \frac{ρ _{o bj}}{ρ _{f l u i d}} = \frac{600}{1000} = 0.60 F_{b} = ρ_{f l u i d} g V

Reading this result: Lighter than the fluid (ρ ratio 0.60), so it floats with exactly 60% submerged — the submerged fraction equals the density ratio, and object size never changes it.
