How It Works
This simulator uses realistic physics to model rocket launches from
Earth to any destination in space. The simulation considers:
- Atmospheric drag effects
-
Rocket propulsion and fuel consumption
- Gravity turn maneuvers
An advanced optimizer calculates the most efficient trajectory based
on your rocket's parameters and destination.
Key Rocket Parameters
Dry Mass
Mass of the rocket without fuel (kg)
Initial Fuel
Starting fuel mass (kg)
Burn Rate
Fuel consumption rate (kg/s)
Specific Impulse
Engine efficiency (seconds)
Turn Start Altitude
When to begin gravity turn (meters)
Turn Rate
Angular velocity during turn (deg/s)
Physics Calculations
Thrust Force
Fthrust = ṁ * Isp * g0
Where ṁ is fuel flow rate, Isp is specific impulse, and
g0 is gravity at sea level
Drag Force
Fdrag = 0.5 * ρ * v2 * Cd * A
Where ρ is air density, v is velocity, Cd is drag
coefficient, and A is cross-sectional area
Gravity Force
Fgravity = G * Mearth * m / r2
Where G is gravitational constant, Mearth is Earth's
mass, m is rocket mass, and r is distance from Earth's center
