Standard aerodynamic models break down after 20 degrees, failing to predict spins or stalls. For realistic flight simulation, developers need data that covers the entire flight envelope. SimiFoil, born from the SimiFlight simulator project, generates continuous aerodynamic curves for any angle of attack, filling a critical gap for game engines and RC aircraft.

Unlike complex CFD software, SimiFoil prioritizes stable, simulation-friendly data over absolute precision. It handles everything from classical airfoils to unconventional shapes like flat plates and thick trailing edges. The tool was validated against historical NACA wind tunnel data, proving its analytical model holds up even in extreme conditions.

A free web demo is available now for exploring lift and drag coefficients, though file export is disabled. A standalone desktop version with CSV and XFoil export is imminent. This tool gives indie developers and hobbyists a practical way to simulate aerobatics and post-stall behavior without expensive software.
