Abstract:

An expert system-based computer assisted design CAD package for propellant formulation design has been created for use on an Intel 8028680386- based workstation PC. This CAD package is intended for use by propellant formulators as a tool to aid in the design of, and properties estimation for, new rocket and gun propellants. A backward-chaining expert system shell Level 5, dBase III-compatible databases, and a PC version of the NASA-Lewis thermochemical code CET89 are linked together into one package. Properties estimation is accomplished via the use of both the expert system shell and the CET89 code the thermochemical code options RKTT rocket calculation and UVT constant volume are supported. The initial version of this expert system has been implemented for a propellant formulation consisting of three ingredients binder, plasticizer, and energetic material. Current research efforts are going into the design of a more comprehensive package for use with up to 21 propellant ingredients.
