You are conducting an initial design of a two stage space lift rocket system. The system must deliver a total AV=10 km/s to a 2,000 kg payload. The total mass of the second stage structure is 3,000 kg and carries 9,000 kg of propellant with an Isp=400 sec. The first stage structure is 8,000 kg and carries a propellant with Isp=350 sec. How much propellant (mass) needs to be loaded in stage 1?

1. Assume a Centaur V upper stage with an empty mass of 2,247 kg, diameter of 3.05 meters and height of 12.68m, the wall thickness is 41mm, whereas the motor can be assumed to fill up 1/4 of the inner volume. You can assume the density of the walls and the motor to be uniform. You can assume the upper stage has been properly passivated and has no fuel remaining.

QUESTION 1 (COLLAB) A new design of Saturn 17 rocket with mass 1.48 x106 kg has a propulsion engine that can eject gases at a constant speed of 241.89 m/s (vGas) by burning fuel at a rate of 2.11 x10 5 kg/s (dmdT). In full tank, the rocket can carry a fuel of mass 40.51 x10 6 If this design exceeds the velocity of 11,200 m/s it can can successfully escape Earth's gravity. Determine if this is so. Find its maximum velocity (velyz). (Pitch Angle = 0) kg.
