Abstract:

A method has been devised which allows one to compute the tolerances of dimensions of a projectile or other manufactured item in such a manner as to minimize the costs of production. The method further allows the imposition of any number of inequality constraints tolerances on properties of the dimensions weight, volume, center of mass position, etc., which will be satisfied to a linear approximation. A particular form hyperbolic for the cost function has been chosen as the example here computed, but the method is not limited to this form. A computer program to facilitate numerical application of this technique has been written, and another program to compute the required sensitivity coefficients for three dimensional mass asymmetry limits is presently in development.
