A Concept of Live Fire Testing to Identify the Aerodynamic Coefficients of a 35 mm Anti-Aircraft Projectile [PDF]

open access: yesProblemy Mechatroniki, 2019
This paper presents a generic algorithm designed to identify aerodynamic coefficients among the data specified in firing tables and projectile flight parameter data recorded during live fire tests. The algorithm and the concept of live fire testing shown

Ballistic Anisotropic Magnetoresistance [PDF]

open access: yesPhysical Review Letters, 2005
Electronic transport in ferromagnetic ballistic conductors is predicted to exhibit ballistic anisotropic magnetoresistance (BAMR) - a change in the ballistic conductance with the direction of magnetization. This phenomenon originates from the effect of the spin-orbit interaction on the electronic band structure which leads to a change in the number of ...

Approximate ballistics formulas for spherical pellets in free flight

open access: yesDefence Technology, 2018
The ballistics equations for spherical pellets in free flight are simplified through appropriate scaling of the pellet velocity and pellet distance. Two different drag coefficient curves are averaged to yield a single curve applicable to shot pellets and
