Ballistic Coefficient Estimation for Classification of Projectiles

Shallow Angle Water Entry of Ballistic Projectiles

The water-entry of ballistic projectiles is investigated using high-speed digital imaging to capture the subsurface cavity dynamics. Specially designed 0.22 caliber projectiles are fired into water at shallow angles to the free surface (5◦ to 15◦) at Mach numbers between 0.3 and 1.0. Redesigned projectile tip geometries allowed projectiles to successfully enter the water and travel large distan...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Optical Flow-Based State Estimation for Guided Projectiles

Ballistic Resistance of Steel Plate Hardox upon Impact of Non-Penetrating Projectiles

A steel plate material Hardox can be used also as a core design material for the production of ballistic barriers or traps at the shooting ranges for small arms. The article deals with the results of experiments with shooting weapon systems of a high ballistic performance and with Finite Element Method simulation of the projectile penetration upon the steel plate using the software Ansys Autody...

J Clasper. The Interaction of Projectiles with Tissues and the Management of Ballistic Fractures.

Wounds to the limbs are the commonest injuries seen during armed conflict and injury results from the transfer of energy from the missile to the tissues. There are a number of factors that determine the transfer of energy, and thus the extent of wounding. These include the velocity of the missile, its shape and stability, and the tissue through which the missile passes. Many of the wounds invol...
