External Ballistics of Powder under Detonation Spraying

International Thermal Spray Conference, 2009
Abstract This study investigates the influence of spraying distance and substrate orientation on the formation of metallic coatings by detonation spraying. Deposition efficiency was determined for aluminum, copper, titanium, and steel powders sprayed at different distances on substrates oriented at different angles. The results show that

A Detailed Analysis of External Ballistics and a Study of Factors Affecting the Projectile Range

Machine Building and Energy: New Concepts and Technologies (2nd MBENCT)
Ballistics is the science and dynamics of a moving projectile. This field helps to understand the accuracy of different projectiles, from bullets to rockets. Ballistics is based on physics, particularly Newtonian mechanics, and plays an important role in

Fractional hyper-ballistic transport under external oscillating electric fields

Chaos: An Interdisciplinary Journal of Nonlinear Science
The generalized Langevin equation (GLE) for a tagged particle in a liquid of charged particles under the influence of external AC electric fields is studied. For the fractional memory kernel in the GLE, the mean square displacement (MSD) of the particle is studied analytically in both the underdamped and overdamped regimes.

External ballistics task modelling features

2012
Based on the solutions of an external ballistics task, tables are made for firearms and tables or computer control programs for heavy weapons. If you shoot in a mountainous area where the height difference between gunner and target can be about a hundred meters, defined skills for firing are necessary.

Influence of pellet seating on the external ballistic parameters of spring-piston air guns

International Journal of Legal Medicine, 2016
In firearm examiners' and forensic specialists' casework as well as in air gun proof testing, reliable measurement of the weapon's muzzle velocity is indispensable. While there are standardized and generally accepted procedures for testing the performance of air guns, the method of seating the diabolo pellets deeper into the breech of break barrel ...
