# What is the distribution of ∆V amongst different stages of rocket flight?

How is rocket energy (or fuel consumption) is distributed between

1. gaining orbital velocity
2. gaining orbital height
3. fight aerodynamic drag
• take a spacecraft to LEO and gain orbital velocity are more or less the same. Maybe you mean gravity drag instead of take a spacecraft to LEO – Antzi Dec 13 '17 at 9:46
• You may distinguish between gaining orbital height, gaining orbital velocity and fighting atmospherical drag. – Uwe Dec 13 '17 at 10:08
• Yes, I mean gravity drag – Pavel Bernshtam Dec 13 '17 at 10:36
• Calculating the kinetic and potential energy for 1. and 2. is very easy, but to calculate the energy to fight drag is very difficult. Formulas for the kinetic and potential energy are found on this page. But the text is in german only. – Uwe Dec 13 '17 at 10:44
• I'm asking just about order of magnitude - like 10%/70%/20% – Pavel Bernshtam Dec 13 '17 at 11:01
