TABLE OF CONTENTS Program CADAC, Computer Aided Design of Aerospace Concepts, provides an environment for the development of general purpose, digital computer simulations of time-phased dynamic systems. It manages input and output, generates stochastic noise sources, controls state variable integration, and provides postprocessing analysis and display. CADAC has proven its adaptability to many simulation tasks: air-to-ground and air-to-air missiles, ground-to-space and space-to-ground vehicles, and airplanes. The CADAC environment is suitable for three-, five-, and six-DoF simulations. It supports deterministic and Monte Carlo runs. Output can be listed or plotted.
CADAC is hosted on an IBM-compatible PC with a minimum of 32 MB of RAM, 25 MB of free disk space, and Microsoft's Window operating system. The graphics utilities are best displayed on a 1024 768-resolution screen with font size set to small.
CADAC consists of CADAC Studio and CADAC Simulations. Both can be downloaded from the CADAC Web site (go to http://www.aiaa.org, under Market Pulse, select Web Links to find CADAC among a list of aerospace-related links). CADAC Studio, written in Visual BASIC, analyzes and plots the output with programs KPLOT and SWEEP and provides utility function for debugging. The vehicle simulations are written in FORTRAN 77 with some common language extensions. The preferred compiler is Compaq's (formerly Digital) Visual FORTRAN for Microsoft's Developer Studio. Other compilers (like Silicon Graphics) may require minor modifications of the CADX3.FOR executive routine.
The CADAC Studio comes with four volumes of documentation:
Quick Start gets you started with the test case and provides an...
