Two engineering simulators I built to understand how things fly. They run right in your browser.

AeroTunnel: smoke flowing around an airfoil in a 2D wind tunnel

AeroTunnel

Created 7 Oct 2025

A 2D wind tunnel. Pick an airfoil, flat plate or cylinder, change the angle of attack and wind speed, and watch the airflow. It shows lift, drag, L/D and when the wing stalls.

Drone Simulator

Created 10 Jan 2026

A 3D drone design tool. Change the frame, motors, propellers and battery and see how they affect flight time, thrust, stability and payload.
