2D Rocket Ascent: Tsiolkovsky Δv & Loss Budget

2D rocket-ascent simulator built on real physics: propellant mass depletion, thrust-to-weight, gravity turn, atmospheric drag and gravity losses. Watch the Tsiolkovsky Δv budget spend itself in real time and see whether your rocket has enough left to reach orbit.

2D companion to the 3D Rocket Launch flight visualization: instead of a chase-camera view of the vehicle, this simulator is a Δv-budget instrument — it numerically integrates thrust, propellant depletion, gravity loss and atmospheric drag every physics step, then breaks down exactly how much of the ideal Tsiolkovsky Δv survived to become real orbital velocity. Tune payload, propellant load, thrust, specific impulse and the gravity-turn profile, stage the vehicle, and watch whether your rocket clears the 100 km Kármán line at orbital speed or falls short.
