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

Reduced Order Method Applied to Optimization of External Ballistics

Volume 5: Dynamics, Vibration, and Control
Abstract This study explores the application of Reduced Order Methods (ROM) in external ballistics, a domain traditionally less focused on than terminal ballistics. The primary objective is to evaluate the effectiveness of ROM in decreasing computational times during the design of modern Direct Fire Control Systems (DFCS).

An External Ballistics Fitting Method Based on the Support Vector Machine

Advanced Materials Research, 2013
It 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.

EXTERNAL BALLISTICS: PARAMETER ESTIMATION USING POD-RBF

Ballistics 2025
When studying the dynamics of a bullet’s trajectory, multiple variable effects can be measured to attain predictive depiction of the bullet’s behavior. Much of this data has been studied and tested with proven success of limited predictive value. The goal of this paper is to create a reliable model for estimating the trend of how the speed of the ...
