Orbit cranking a.k.a. orbit pumping
is a process that changes the plane
of an orbit
while keeping the altitude
the same. Orbit cranking requires a lot of propellant
and is not a very efficient
method to get into a desired orbit
The required delta-v for orbit cranking is given in the equation below.
del_v = 2 Vcsin(alpha/2)
Where Vc is the velocity required to maintain the current altitude.
Alpha is the desired change in orbital inclination (in radians, not degrees)
