Models and Methods for Three External Ballistics Inverse Problems
Bulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2017 We consider three problems of selecting optimal gun barrel direction (or those of selecting optimal semiaxis position) when firing an unguided artillery projectile on the assumption that the gun barrel semiaxis can move in a connected nonconvex cone having a non-smooth lateral surface and modelling visibility zone restrictions.

A diagram to facilitate the study of external ballistics [PDF]
Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1916 Abstract The semi-graphical method about to do described enables solutions of many dynamical problems of a practical nature to do obtained with ease and rapidity. In particular, useful solutions can be found of problems relating to motion in a resisting medium in cases where the resistance is given as a function of the velocity which ...
