b. A space vehicle is to be designed to deliver a 500 kg satellite into a low earth orbit for which the required velocity increment is 9,140 m/s. It has been decided to use a liquid oxygen & kerosene propulsion system for which the effective exhaust velocity, C, is 3,050 m/s. Calculate the difference in initial take-off mass of the vehicle if a single stage rocket is used compared to that of a two stage rocket. In both cases, assume that the dead-weight ratio is 3%. For the two stage rocket, assume that half the velocity increment is delivered by each stage. You are to neglect gravitational and drag effects. (15 Marks) b.
