sci.spacecraft-delta-v-Hohmann Calculator
Calculates Hohmann transfer orbit delta-v and transit time for orbital plane changes between two circular orbits. Hohmann transfer from LEO (400 km) to GEO (35,786 km) requires Δv_total = 3.93 km/s and takes 5.25 hours — it is the most fuel-efficient 2-burn transfer for coplanar orbits.
Inputs
R1 Km
Distance from centre to edge of a circle. Radius = diameter / 2.
R2 Km
Distance from centre to edge of a circle. Radius = diameter / 2.
M Central Kg
Total mass of the body. Used with height to calculate BMI and estimate lean mass.
Results
total Δv required (km/s)
The combined total across all inputs and components.
Δv₁ — initial burn (km/s)
Sample size or count used in the calculation.
Δv₂ — circularization burn (km/s)
The value at the specified point or condition.
transfer time (hr)
The computed duration or time value.
Hohmann transfer
Sample size or count used in the calculation.
