TL;DR: In this paper, a user friendly shooting simulating process and training system is provided to more accurately and reliably detect the impact time and location in which a projectile shot from a shotgun, rifle, pistol or other weapon, hits a moving target.
Abstract: A user friendly shooting simulating process and training system are provided to more accurately and reliably detect the impact time and location in which a projectile shot from a shotgun, rifle, pistol or other weapon, hits a moving target. Desirably, the shooting simulating process and training system can also readily display the amount by which the projectile misses the target. The target impact time is based upon the speed and directions of the target and weapon, as well as the internal and external delay time of the projectile. In the preferred form, the training system includes a microprocessor and special projectile sensing equipment, and the targets and projectiles are simulated and viewed on a virtual reality head mounted display.

TL;DR: In this paper, the authors described a semi-automatic rifle with a super critical state in chamber by heating element to induce a phase change such that the liquid becomes a highly dense gas.
Abstract: Rifle (1) comprises barrel (2) and loading means (15) for introducing a projectile from magazine (7) into breech (4). The projectile is propelled by a compressed gas propellant initially stored as a liquid in canister (10). The liquid is heated to a super critical state in chamber (8) by heating element (12) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel the projectile at high velocity from rifle (1), regardless of the ambient temperature. The propellant is preferably CO2 which is heated to 31.06 °C. Rifle (1) produces minimal noise and no heat signature, making it suitable for military and stealth purposes. A pistol and launchers for grenades or mortar bombs are also disclosed. Another version can launch low earth orbit satellites or payloads.

TL;DR: In this paper, the effects of a hard impact on a concrete barrier wall are discussed. But this paper only deals with the effect of "hard" missile impact and does not deal with the impact on "soft" barrier walls.

Journal ArticleDOI
TL;DR: In this article, an experimental investigation was carried out to study the behavior of square thin-walled aluminium extrusions in alloy AA6060 subjected to axial loading, and both static and dynamic tests were performed and the primary variables were the wall thickness and temper of the square tubes and the impact velocity of the projectile.
