Aerodynamics

What the air does back.

Push on the air and it pushes back — lift when you arrange the push cleverly, drag always. This library holds the canonical deep dives: a live wing solver, the car-aero tricks that reshaped racing, and the theory course underneath it all.

Wings, live

The flagship: a vortex-panel solver on a wing section you shape yourself.

Live

Aerofoil Playground

Draw a wing section and a real vortex-panel solver computes its pressure field and lift, live. Angle of attack, camber, thickness, stall — the whole conversation between a wing and the air.
