Introduction Chemical propulsion contributes greatly to our understanding of the universe, our quality of life, and our national security. Rockets have propelled man to the moon, sent probes to the planets, and placed the Hubble Telescope in space to study the universe. Satellites placed in orbit provide intelligence information vital to our national security. CPIA's mission is to serve as the national clearinghouse for world wide data and analysis on chemical, electrical, and nuclear propulsion for missile, space and gun propulsion systems.
All codes are available in a variety of media types.
The price of the codes includes source and documentation reproduction, application processing and mailing. It has also been used for analysis of solid rocket motor plume contamination. The code uses a finite element mesh to describe the propellant grain. The burn rate variation within the grain due to casting effects, strain level, and propellant properties variations can be input in a 3D table form. The grain regression algorithm is a direct physical simulation of the burning process and follows burning surface elements.
