An effort to improve the performance of ordnance has led to the consideration of the use of folding elliptical fins for projectile stabilization. A second order differential equation was used to model elliptical fin deployment history and accounts fo

Throughout its development, slender body theory has been generalized to predict a large variety of aerodynamic coefficients for a wide class of flight bodies. For most applications, slender body theory provides only a qualitative predictive capabilit

With the recent development of capabilities for predicting damping derivatives, it is now possible to predict the stability characteristics and free-flight motion for projectiles using data that are derived solely from computational fluid dynamics (C

A detailed numerical investigation of the interaction between a lateral jet and the external flow has been performed for a variety of missile body geometries. These include non-finned axisymmetrical bodies and finned bodies with either strakes or aft

The influence of quasi-independent parameters and their potential influence on erosion in guns have been investigated. Specifically, the effects of flame temperature and the effect of assuming that the Lewis number (ratio of mass-to-heat transport to

This report presents a simple but accurate method of determining the trajectory of projectiles that traverse a flight regime that includes supersonic, transonic, and subsonic flight. Closed-form analytical solutions for the important trajectory param

An approach for predicting the two individual aerodynamic damping coefe cients that form the pitch-damping coefe cient sum is presented. The coefe cients are obtained using prescribed or forced motions that independently excite the two different angu
