Calculadora de Transferencia de Hohmann — Fórmula
## Hohmann Transfer Orbit
A Hohmann transfer is the most fuel-efficient two-impulse manoeuvre between two coplanar circular orbits.
### Key Equations
1. **dv1 = v1 (√(2 r2/(r1+r2)) - 1)**
2. **dv2 = v2 (1 - √(2 r1/(r1+r2)))**
3. **Transfer time = π √(a_t³ / (G M))** where a_t = (r1 + r2)/2

Ejemplo Resuelto
Transfer from LEO (200 km alt, r1 = 6 571 km) to GEO (r2 = 42 164 km).
- v1 = √(GM/r1) ≈ 7 789 m/s
- dv1 = 7789 × (√(2×42164/(6571+42164)) - 1) ≈ 2 457 m/s
- v2 = √(GM/r2) ≈ 3 075 m/s
- dv2 = 3075 × (1 - √(2×6571/(6571+42164))) ≈ 1 478 m/s
- Total dv ≈ 3 935 m/s
