Hohmann Transfer: Maximum Radii Ratio

  1. Apr 15, 2010 #1
    Hello everyone,

    I'm working on a problem where I had to find the ∆V's at the aphelion and perihelion for a Hohmann transfer, which I did. However, I am being asked to prove how for the total ∆V for the transfer has a maximum R1/R0 = 15.6 (R0 is the radius of the original circular orbit and R1 is the radius of the second circular orbit after the two boosts). I want to know how to obtain the value 15.6.

    I was going to take a derivative of the equation, set it equal to 0, and solve for the maximum that way...but I'm thinking this is wrong...Any suggestions?

    Welcome to PF!

    I am not aware if there is a shortcut somehow, but if you follow through on your own suggestion then you should
    end up with the value you are supposed to.
