The Evolution of Air Threats in Future Conflicts

open access: yesSafety & Defense, 2023
Currently, there is an observable trend towards continuous and comprehensive development in both fixed-wing and rotary-wing aircraft design. Furthermore, a dynamic progression has been also witnessed in the evolution of unmanned aerial vehicles ...

A study on the energy dissipation of several different CFRP-based targets completely penetrated by a high velocity projectile [PDF]

open access: yes, 2009
The threat of fragmenting munitions from MANPADS to civilian and military aircraft has, in recent years, become an ever increasing worry. One of the ways to enhance the protection of CFRP-based composites is to add lightweight materials that can provide ...

Efficient circuit-level modelling of ballistic CNT using piecewise non-linear approximation of mobile charge density [PDF]

open access: yes, 2008
This paper presents a new carbon nanotube transistor (CNT) modelling technique which is based on an efficient numerical piece-wise non-linear approximation of the non-equilibrium mobile charge density.

Układ INF – zimnowojenny fundament bezpieczeństwa europejskiego [PDF]

open access: yesNowa Polityka Wschodnia, 2019
The INF treaty, which was signed by R. Reagan and M. Gorbachev in 1987, banned ballistic and cruise missiles with a range from 500 to 5500 km. It was the first disarmament treaty that completely eliminated the entire class of already existing weapons ...

Investigating Ballistic impact on fabric targets with gripping yarns [PDF]

open access: yes, 2013
The purpose of the research is to investigate the fabric structure (with gripping yarns) in the influence of ballistic performance; therefore to improve the ballistic performance of the current used body armour materials.

INS Stochastic Noise Impact on Circular Error Probability of Ballistic Missiles

open access: yesNavigation, 2022
A circular error probability (CEP) metric in ballistic missile science is an experimental indicator of the accuracy of a missile system. There are a lot of error sources that cause a ballistic missile to deviate from its ideal trajectory, and that causes

Ballistic behaviour of explosively shattered alumina and silicon carbide targets [PDF]

open access: yes, 2011
The resistance offered by three ceramic materials of varying strength that have been subjected to explosive loading has been investigated by depth-of-penetration testing.
