Atomic Rocketships of the Space Patrol

"Your imagination has been captured by the roaring rockets from Heinlein's SPACE CADET or the Polaris from TOM CORBETT, SPACE CADET. But are such rockets possible? How does one go about defining the performance of these atomic-powered cruisers?
This document gives some hints and equations that will allow back-of-the-envelope calculations on such matters. Though horribly simplistic, they are far better than just making up your figures.
This site was mainly intended for science fiction authors who wanted a little scientific accuracy. But anybody who is interested can play with the toys contained within, designing their own Planet Rangers Rocketships. It is assumed that the reader has enough knowledge to know the difference between a star and a planet, and enough skill to use a pocket calculator. Computer spreadsheet and computer programming skills are a plus, spreadsheets in particular will make your life much easier."
