Why is Hohmann transfer most efficient?
Why is Hohmann transfer most efficient? The most energy-efficient way to move between circular orbits is the Hohmann transfer orbit [1]. The first burst of thrust is calculated so that the maximum altitude of the resulting elliptical orbit is the desired altitude of the new circular orbit. Why is Hohmann transfer efficient? The Hohmann transfer […]
