INTERPLANETARY GUIDANCE SYSTEMS REQUIREMENTS STUDY VOLUMEⅡ COMPUTER PROGRAM DESCRIPTIONS PART 5 NOMINAL ATMOSPHERIC ENTRY TRAJECTORIES VERSIONⅠ

摘要

This document describes a digital computer program developed to simulate the single pass and single skipout trajectories for a lifting-type vehicle during atmospheric entry. The description includes a mathematical model, a computer program description, a user's guide, an operator's and programmer's guide, a test case, and a program listing. The mathematical model describes the equations used in generating the tra-jectory. The computer program description includes flow charts and detailed equations, on which the development of the computer program was based. It was written in FORTRAN IV for the IBM 7094 system.
