On the Optimum Size of Orbital Carrier Vehicles Based on Overall Economy
This study is a first and rather crude attempt to develop a procedure which can supply the answer as to whether, and when, we need larger launch vehicles than currently developed. The preliminary results of numerical calculations indicate the trends to be expected. It is concluded that operational considerations, rather than economy, will determine the vehicle size, since much larger vehicles would result in only small savings in cost.
