Air Trail

Air Trail puts the physics of flight in your hands. Choose from six simulation types — from a simple ball throw to a rocket launch — configure your launch parameters, and watch your projectile arc through the sky with pinpoint accuracy. Powered by fourth-order Runge-Kutta (RK4) numerical integration, Air Trail models gravity, aerodynamic drag, wind, and air density simultaneously for results that match real-world physics.

Tweak every variable that matters. Set your initial velocity, launch angle, mass, and drag coefficient. Dial in the environment — Earth, Moon, or Mars gravity, headwinds, crosswinds, altitude, and air density. Six preset scenarios (Ball Throw, Archery, Paper Plane, Drone Flight, Rocket Launch, and Custom) give you a ready-made starting point, or save your own custom presets for instant reuse.

Dive into your results with five powerful analysis tools: an animated trajectory playback at 0.5×–4× speed with live parameter adjustment, interactive height/velocity/distance graphs exportable as PNG, a scrollable raw data table, a side-by-side Comparison Mode, and a shareable formatted report. The Laboratory overlays up to five trajectories at once so you can see exactly how angle and velocity trade off. Set a goal before each run — distance, max height, or flight time — and Air Trail tells you whether you hit the mark.

Track every run in your simulation history, mark favourites, unlock nine achievements, and review aggregated stats across all your launches. Whether you are a student exploring classical mechanics, a teacher building live demonstrations, or simply curious what happens when you fire a rocket from the surface of Mars — Air Trail gives you the tools to find out.
