Data for Estimating Rocket Payloads in Twodimensional Minimum Energy Orbits Through the Solar System

摘要

Data are presented as guides to show some of the quantitative relationships which exist among bodies of the solar system, and to indicate the influence of these bodies on vehicles traveling within the solar system. Information is given which describes the sun, the nine planets and their satellites with respect to general orientation, motion, size, mass, and the manner in which their gravitational attractions and escape velocities decrease with increasing distance. Curves are presented for the sun, the first six planets and the moon to show what velocity is required to move from an intitial distance to a final distance from each body along a minimum energy (Hohmann) ellipse. Data are given which show the influence of various planets and the moon, on vehicles leaving or approaching these bodies along two-dimensional hyperbolic trajectories. The performance of a single stage rocket is given by showing in graphical form the ideal rocket equation.
