Thank you for your answer... Could you tell me if this is correct?: The final mass of the rocket is the result of stage 2 structure mass + payload mass (because the fuel is totally exhausted at that point) so, the initial massof stage 2 will be mf*e(delta-v/C)...Then, the final mass of stage 1...

Thank you so much. I hope so.

Homework Statement [/B] I was wondering if you'd be able to help me with this problem: Given a two-stage launch vehicle with an engine that produces an Isp =400 sec, a payload mass of 10.000 kg, stage 1 structure mass of 10.000 kg, stage 2 structure mass of 10.000 kg, determine the mass ratio...

Hello, I'm an engineering student, I hope that I will learn many interesting things here and I will do my best to help everybody that I can.
