Missile total and subsection weight and size estimation equations

Abstract

This study utilizes regression analysis to develop equations which relate missile overall and subsection weights and geometries, including wings and fins, to variables which are considered to be the input for a new design in the conceptual or preliminary design phase, These variables include packaging requirements such as maximum length, diameter and weight, as well as performance characteristics such as mission an range. Data for this analysis was collected from a variety of military, industrial and academic sources. The generic missile is split into three subsections: propulsion, guidance and control, and warhead. Utilizing single and multi-variable regression analysis, weight estimation equations are developed for the total missile, subsections, and wings/fins based on categorizing the missile by mission, air-to-air, air-to-surface, surface-to-air, or surface-to-surface; and by range: short, medium, or long. Measures of fit are developed and displayed with their associated equations to aid in selection of the optimum equation.
