Aberdeen Proving Ground, Md: Ballistic Research Laboratory, 1979, - 31 p.Interior ballistic models are available for the design of new guns, improving the performance of existing guns, and solving problems in existing guns. The type of models available can be classified into empirical and semi empirical classes. The semi empirical models are subdivided further into the closed-form solution, the numerical solution to the governing ordinary differential equations, and the numerical solution to the general partial differential equations. The performance of these models for gun design, improvement, and other problems will depend upon how well the model is matched to the problem. Data used by these models are a critical limitation on the predictive accuracy of the model and will strongly influence the results obtained by the user of the model.
