Rocketry Lab

A practical sandbox for flight modeling (2D point-mass). Tune thrust, burn, drag, wind, and launch angle—then read out range, max altitude, flight time, and impact speed.

Inputs

Initial mass (kg)Mass flow (kg/s)Thrust (N)Burn time (s)

Prop mass (kg): 3.000

Dry mass (kg): 7.000

Drag coefficient (Cd)Reference area (m²)Launch angle (deg)Wind X (m/s) — downrange (+)Wind Y (m/s) — up (+)Time step dt (s)Max simulation time (s)

Used as a safety cap. Simulation stops earlier if the rocket lands.

PlotRecord trajectory (for plotting)

Run a sim to see plot + summary.

Output

Plot is intentionally simple and robust. Next obvious upgrades: velocity, acceleration, forces, thrust curves, pitch program, and 2D path view.
