Influence of Silencer Use on External Ballistics of Projectiles
30th International Symposium on Ballistics, 2017The following article is a summary of the first step of research on behavior of sniper rifles in calibers .308 Winchester, .300 Winchester Magnum and .338 Lapua Magnum with and without sound suppressor. The paper includes measurements of chosen external ballistics parameters like velocity and accuracy at 300 m (328 yd) with the use of state of the art ...

External Ballistics and Accuracy of Lead Free Bullets in 5.56x45mm NATO
30th International Symposium on Ballistics, 2017Several nations have moved to lead free bullets in 5.56x45mm NATO for use as duty ammunition by military personnel. This study reports on the external ballistics and accuracy of two lead free bullet designs that have been fielded to date, the 62 grain lead free hard core bullet manufactured by RUAG and the 62 grain lead free bullet manufactured by ATK ...

A MODIFIED MODEL OF EXTERNAL BALLISTICS FOR SUPERSONIC MORTAR PROJECTILES
PROBLEMY TECHNIKI UZBROJENIA, 2018Basic models applied for analysing and modelling the flight parameters of projectiles were disscussed in the article. A modified model with five degrees of freedom and neglection of the sixth one, representing the projectile rotation speed, is proposed by authors on the basis of conducted analysis to analyse flight parameters of a supersonic mortar ...

Modeling and Simulation of External Ballistics of New Air-Defence Guided Projectile
2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2019The method of three-dimensional ballistic modeling and simulation of shipborne air-defence guided projectile is discussed. Firstly, the force and guidance law of the projectile are analyzed, and taking the proportional guidance as an example, the method ...

An External Ballistics Fitting Method Based on the Support Vector Machine
Advanced Materials Research, 2013It is because of many reasons the trajectory calculated from the theoretical model and the actual trajectory have some error, so the experimental results on the theoretical trajectory must be corrected. In this paper, two degrees of freedom of particle trajectory equations are used to determine the ballistic coefficient.
