Models and Methods for Three External Ballistics Inverse Problems

open access: yesBulletin 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]

open access: yesProceedings 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 ...

Estimate of projectile initial velocity as a solution of a two-point boundary value problem / Оценка начальной скорости снаряда как решение двухточечной граничной задачи / Procena početne brzine projektila kao rešenje problema granične vrednosti za dve tačke [PDF]

open access: yesVojnotehnički Glasnik, 2018
The estimating of a projectile initial velocity is formulated as a two-point boundary value problem. To solve it, the data of a Doppler Radar or the results of solving the Cauchy problem can be used.
