A two stage chemical rocket, having the same specific impulse (l9p) of 300 s for both the stages is
designed in such a way that the payload ratio and the structural ratio are same for both the stages.
The second stage of the rocket has following mass distribution:
Propellant Mass=10208 kg
Structural Mass=1134 kg
Payload Mass=1700 kg
gc=9.8 m/s2
If the rocket is fired from rest and it lies in a zero gravity field and a drag free environment, the
final velocity attained by the payload is
designed in such a way that the payload ratio and the structural ratio are same for both the stages.
