Ballistic resistance of steel targets is important due to its common application to the safety of personnel, shelters for arms and military vehicles. Protective systems should provide a safer condition against possible threats by reducing the weight and the volume they occupy. This causes the total weight of the armor to decrease and increases the mobility of armored vehicle. This study concerns behavior of metallic plates that are spaced and obliquely arranged in order to increase ballistic resistance against projectile penetration. Investigations are made for target configurations having various areal densities. The scope of the work also includes different orientation of single and multiple layered mild steel plates. The main effort is to seek for a better alternative layered-armor structure which provides higher protection by reducing the total weight of armor structure. The impact tests are simulated using ABAQUS/Explicit finite element software. Numerical and experimental studies revealed that it is possible to reduce the armor weight by 48% to defeat 7.62 mm AP projectile utilizing the proper layering.

Investigation of Acoustic Source Localization algorithm performances for Gunshot Localization on helicopters
Yılmaz, Murat; Günel Kılıç, Banu (2016-06-23)
Self-defense solutions on current aircraft usually handle advanced weapons while most helicopters down or damaged are known to be attacked from ground using rifles or Rocket-Propelled Grenades (RPG). Although there are ground based localization solutions for Small Arms Fire (SAF) attacks, there are only a few implementations of onboard applications. A simple Acoustic Source Localization (ASL) application employs a microphone array for collecting audio signals, so as to locate sound sources using the measure...
Effect of Hardness on the Ballistic Impact Behavior of High-Strength Steels Against 7.62-mm Armor Piercing Projectiles
DEMİR, TEYFİK; Ubeyli, Mustafa; Yıldırım, Raif Orhan (2009-03-01)
Ballistic performance of engineering materials should be known in selection of the most suitable armor material to protect civilian or military system with the lowest possible weight against various threats. In this study, the ballistic impact characterization of high-strength steels, namely AISI 4340 and DIN 100Cr6, was investigated using 7.62-mm armor piercing (AP) projectiles by considering four hardness levels and five areal densities. The main aim was to examine the effect of hardness and areal density...
Experimental and numerical investigation of ballistic impact behaviour of high strength aluminium plates
Başaran, Güralp; Gürses, Ercan; Department of Aerospace Engineering (2019)
A hybrid solution method was used to examine the ballistic collision situation to be used in armored vehicle design. This hybrid solution method includes an Artificial Neural Network (ANN) and a Finite Element (FE) solver. MATLAB was used for ANN model, and LSDYNA® was used as FE solver. For this purpose, first ballistic tests were performed, and projectile residual velocities and depth of penetrations were measured. The FE model was confirmed by ballistic tests. After the FE model validation, FE analyses w...
Experimental analysis and modelling of wear in rocket rail launchers
Açmaz, Emre; Akkök, Metin; Department of Mechanical Engineering (2011)
Launchers are military systems that are responsible for communication with munitions, safe seperation and aiming of rockets and missiles to the target. Since they are military equipments, they are used in harsh environments. One of the most important design considerations for military equipment is its maintability and one of the most important parameter which affects the maintability is wear in launchers. Therefore, for predicting the life-time of a launcher, wear should be investigated beside other paramet...
A REVIEW OF POLYCYCLIC AROMATIC ENERGETIC MATERIALS
Türker, Burhan Lemi; Varis, Serhat (2009-01-01)
Explosives are employed extensively not only in military areas but also in civilian applications. There are many researchers working on the discovery of explosives. In recent years, synthetic and theoretical studies on polycyclic aromatic explosives have received significant interest. The present short review concentrates on the synthesis and some of the physico-chemical characteristics of energetic materials of the classes of tetraazapentalene, naphthalene, di-and tetraaza-naphthalene, pyrazolo-pyrazole, b...
