The influence of the drag force on the safety domain
Revista Brasileira de Ensino de FísicaIn this work we compute the safety domain related to projectiles fired close to the Earth's surface, taking into account a linear (laminar regime) and a quadratic drag force (turbulent regime).

Modeling of Dual-Spinning Projectile with Canard and Trajectory Filtering
International Journal of Aerospace Engineering, 2018 The article establishes a seven-degree-of-freedom projectile trajectory model for a new type of spinning projectile. Based on this model, a numerical analysis is performed on the ballistic characteristics of the projectile, and the trajectory of the dual-

Carbon Energy, EarlyView.The 0D/1D grain boundary coupling between Fe₃O₄ quantum dots and CNTs induces extreme charge redistribution and short‐range magnetic resonance, enabling complete electromagnetic wave absorption across the entire X and Ku bands. ABSTRACT Ferrite–carbon composites effectively absorb electromagnetic (EM) waves via coupled mechanisms.
