Hohmann Transfer Calculator
Calculate orbital transfer parameters between two circular orbits using the Hohmann transfer maneuver. Essential for aerospace engineering, orbital mechanics, and space mission planning. Computes delta-v requirements, transfer time, and orbital velocities for satellite deployment.
Hohmann Transfer Delta-V
Δv₁ = √(GM/r₁) × (√(2r₂/(r₁+r₂)) - 1)Keterangan:
- ΔvVelocity change (m/s)
- GMStandard gravitational parameter (m³/s²)
- r₁Initial orbit radius (m)
- r₂Target orbit radius (m)
How to Use
- 1
Input Orbit Awal
Enter jari-jari orbit awal (m).
- 2
Input Orbit Tujuan
Enter jari-jari orbit tujuan (m).
- 3
Input GM
Enter parameter gravitasi (default: Bumi).
- 4
Calculate

Contoh Perhitungan
LEO ke GEO
Soal:
r₁=6771km (LEO), r₂=42164km (GEO), GM=3.986e14. Cari Δv?
Penyelesaian:
- 1.Calculate Δv₁ for naik ke transfer orbit
- 2.Calculate Δv₂ for sirkularisasi di GEO
Hasil:Δv₁=2.4km/s, Δv₂=1.5km/s, Total=3.9km/s
Total delta-v sekitar 3.9 km/s for transfer LEO ke GEO.
Pertanyaan yang Sering Diajukan (FAQ)
What is Hohmann Transfer?
Maneuver transfer orbit paling efisien (paling sedikit delta-v) antar dua orbit sirkular.
Berapa waktu transfer?
Setengah periode orbit elips transfer, sekitar 5.6 hours for LEO ke GEO.
