Detection of electro-explosive detonators by RF signature

2019
Kılıç, Özgehan
Electro-Explosive Detonator (EED) is the main trigger mechanism in most of the explosive systems. Explosion of these systems start with the burning of the EED bridge wire by excess current, followed by the explosion of higher amount of explosives. Accidental or on purpose explosion of these explosives results in many losses. The electrical properties of the EEDs are modeled at the microwave frequencies, but there is no focus on the detection of EEDs by their RF signature. MUltiple SIgnal Classification (MUSIC) and Prony’s methods are adopted for this purpose, and measurements are conducted for justifying the methods. A Multiple Input Multiple Output (MIMO) measurement system is also setup and detection performance enhancement is achieved by statistical MIMO application.

A Trigonometric Approach to a Limiting Law on Detonation Velocity
Türker, Burhan Lemi (2012-01-01)
Detonation velocity is an important characteristics of explosive compounds. Presently, to get some insight about the detonation velocity, a novel trigonometric model has been suggested first in 2-dimensional form and then extended to 3-dimension. In the 2D-form the detonation velocity is considered to be a function of the total energy and a newly defined "angle of detonation", Q, of an explosive molecule. The angle of detonation velocity is also shown to be a nonlinear function of the total energy. In the 3...
Effect of conducting containment on electromagnetic launcher efficiency
Ceylan, Doğa; Keysan, Ozan (2017-11-02)
Electromagnetic launcher, also called railgun, is a projectile accelerator which uses the electromagnetic force. Existence of solid metal containment around the rails of electromagnetic launchers, which increases the mechanical durability, affects the electromagnetic force on armature and rails. In this study, the effect of distance between non-laminated conducting containment and rails, and the effect of the lamination thickness on the efficiency of railgun are investigated. Also, the effect of magnetic an...
Characterization of electrolyte and pyrotechnic powders and pellets
Kalender, Volkan; Özbelge, H. Önder; Department of Chemical Engineering (2011)
Electrolyte and pyrotechnic pellets are two important components of thermal batteries. Both electrolyte and pyrotechnic pellets are produced by cold compaction of constituent powders. These compacts are integrated in the battery as pellets with sufficient green density, green strength, calorific energy and burning rate (for pyrotechnic only) to provide high performance batteries. In this study, effects of physical properties of the used powders such as particle size distribution, average particle size, part...
Effect of proton scavengers on the textural properties and performance of Fe2O3 xerogels for boron containing pyrotechnics
Yilmaz, Nil E. Dinçer; Karakaş, Gürkan (2017-01-01)
Currently used rockets and missile igniter systems are mostly based on the pyrotechnic blends of fuels and oxidizers. In this study nano-sized boron was used as fuel because of its high heat of combustion, low atomic weight and high energy density. Iron oxide was used as an oxidizer and synthesized by sol-gel method by using various types of proton scavengers. In the experiments Fe(NO3)3·9H2O was used as a precursor and a wide range of proton scavengers (propylene oxide, 1,2 epoxybutane, tetrahydrofuran, te...
One and two dimensional numerical simulation of deflagration to detonation transition phenomenon in solid energetic materials
Narin, Bekir; Bekir, Narin; Department of Aerospace Engineering (2010)
In munitions technologies, hazard investigations for explosive (or more generally energetic material) including systems is a very important issue to achieve insensitivity. Determining the response of energetic materials to different types of mechanical or thermal threats has vital importance to achieve an effective and safe munitions design and since 1970’s, lots of studies have been performed in this research field to simulate the dynamic response of energetic materials under some circumstances. The testin...
