Abstract

Taking a two-stage rocket of series type as an exampl, the result in this paper shows that the higher the effective jet velocity is, the better the rocket is and that the bigger the ratio y_i/x_i or the first stage rocket's mass is, the better the rockt is. However, this conclusion is not suitable to the second stage rocket's mass.but the same isn't true of the second stage rocket's mass.
