Aerospace vehicle synthesis program

Abstract

A modified version of the Aerospace Vehicle Synthesis Program (VSP) to simulate a space shuttle on the computer is presented. The effects of various changes such as payload weight, and orbital velocity can be determined along with minimum costs in vehicle design. The program logic, and weight estimating equations are discussed, and an example case of a solid propellant boosted, drop tank orbiter is included to indicate the type of results produced by the VSP.
