Increasing insensitivity demands on designing and producing munitions necessitates utilizing primarily insensitive initiation trains specifically in missile systems. Exploding Foil Initiator (EFI) is a high voltage detonator that is used as the initiation elementof rocket motor and warhead initiation trains of modern insensitive missile systems. In this thesis, EFI prototypes are designed and manufactured with the knowledge gained from detailed literature studies. An experimental setup is constructed including firing and testing means for EFI prototypes. That experimental setup is capable of firing EFI prototypes from 500 volts to 3000 volts voltage range. Besides, it allows measuring electrical characteristics like current and voltage traces and average velocity of the flyer plates of these prototypes.Using EFI prototypes,detonation tests of HNS – IV and PBXN – 5 explosive pellets are carried out.Function times and detonation outputs of the prototypesare measured with the same experimental setup. A numerical study which predicts electrical performance of EFI prototypes and impact characteristics of flyer plates are carried out. Numerical code is validated with the experimental results.

Missile autopilot design by projective control theory
Doruk, Reşat Özgür; Kocaoğlan, Erol; Department of Electrical and Electronics Engineering (2003)
In this thesis, autopilots are developed for missiles with moderate dynamics and stationary targets. The aim is to use the designs in real applications. Since the real missile model is nonlinear, a linearization process is required to get use of systematic linear controller design techniques. In the scope of this thesis, the linear quadratic full state feedback approach is applied for developing missile autopilots. However, the limitations of measurement systems on the missiles restrict the availability of ...
Evaluation of Acoustic Gunshot Localization Methods on Helicopters with Environmental Sound Simulations
Yılmaz, Murat; Günel Kılıç, Banu (2022-01-01)
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 measurements from the sound field. The aim of this study is to investigate the possibility of Acoustic Gunshot Localization on a helicopter so as to detect and localize SAF attacks, by simulating the effects...
Trajectory optimization of a tactical missile by using genetic algorithm
Özdil, Baran Dilan; Kutay, Ali Türker; Department of Aerospace Engineering (2018)
In this thesis, estimation of an optimal trajectory for a tactical missile is studied. Missile guidance algorithm is developed to achieve a desired mission goal according to some performance criteria and the imposed constraints. Guidance algorithms may include trajectory optimization to shape the whole trajectory in an optimal way, so that the desired performance needs such as maximum impact velocity, minimum time-of-flight or specific crossing angles can be satisfied. By performing missile path planning, a...

Aerodynamic optimization of missile external configurations
Arslan, Kıvanç; Özgen, Serkan; Department of Aerospace Engineering (2014)
In this thesis, design optimization methods capable of optimizing aerodynamic performances of missiles and rockets are developed. Sequential Quadratic Programming (SQP) and Random Search (RS) methods are used for optimization, whereas Missile DATCOM, which is a semi-empirical aerodynamic analysis tool, is used to calculate aerodynamic coefficients of missile configurations. As the first part of the work, capabilities and limitations of SQP and RS optimization methods are investigated on a complex test funct...
