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 parameters such as fatigue etc. This thesis study includes experimental and modeling study about dry sliding wear in some mechanical parts of a typical rail launcher that is used in helicopters. Firstly, measurements about the material loss, which is generated during firing of missiles, were made on launcher components which have interfaces with missile. Then, these results were used to simulate the wear phenomenon by using a commercial finite element program, ANSYS. By the help of finite element model, crack initiation period depending on wear is tried to be evaluated without making additional firing tests.

External configuration design and aerodynamic optimization of modular guided munitions
Gün, Mert; Sezer Uzol, Nilay; Department of Aerospace Engineering (2019)
Guided munitions, also known as gliding missiles, are not stand alone systems; rather, they are converted from a dummy body with the help of guidance kits. Guided munitions are used in great number during military operations, unlike air-to-air or cruise missiles. Guided munitions can be classified in two main sub-categories. First group provides guidance and stability with use of strakes. These type of missiles used for relatively short ranges. Second group has wings instead of strakes and effective in larg...
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...
Numerical and experimental analysis of a piezoelectric flat plate in flapping motion
Harputlu, Özgür; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2014)
The technology of unmanned aerial vehicles (UAV) has a rapid improvement and their use is increasing day by day for military and civilian missions. Developments in production technology enable the fabrication of micro aerial vehicles. Flapping wing systems have an important place among UAVs. These vehicles are superior to fixed wing aircrafts with their high maneuverability and hover capabilities and they can successfully perform many missions in which the fixed aircrafts are insufficient. Developments in m...
Stabilized Finite Element Simulations of Multispecies Inviscid Hypersonic Flows in Thermochemical Nonequilibrium
Cengizci, Süleyman; Uğur, Ömür; Tezduyar , Tayfun E.; Department of Scientific Computing (2022-3)
For both military and civil aviation purposes, rockets, missiles, and spacecraft moving at hypersonic speeds are being utilized in recent years. While these vehicles move at speeds five times the speed of sound or more, they experience many extreme physical and chemical conditions during their flight. Because of molecular friction, such high velocities cause very high temperatures, and these high temperatures result in the excitation of the components of the gas mixture in which the vehicle moves. This situ...
Varying mass missile dynamics, guidance & control
Günbatar, Yakup; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2007)
The focus of this study is to be able to control the air-to-surface missile throughout the entire flight, with emphasis on the propulsion phase to increase the impact range of the missile. A major difficulty in controlling the missile during the propulsion phase is the important change in mass of the missile. This results in sliding the center of gravity (cg) point and changing inertias. Moreover, aerodynamic coefficients and stability derivatives are not assumed to be constant at predetermined ranges; conv...
