Ammunition Transfer System (ATS) is the electro-mechanical system of the Ammunition Resupply Vehicle (ARV) which will be used to meet T-155 mm Fırtına howitzers’ ammunition demand for tactical requirements of higher firing rate by off-road mobility and survivability. The transfer of ammunitions from ARV to Fırtına is to be optimized for an effective improvement of firing rate. In this thesis the transferring order of carried ammunitions is being optimized to minimize the total ammunition transferring time. This transfer problem is modeled as a modification of Travelling Salesman Problem (TSP). The given locations of the ammunitions are treated as cities to be visited and the gripper of ATS is treated as the traveling salesman. By GAMS; the small-size problems are solved optimally but large-size ones get only local optimum. A heuristic algorithm that contains nearest neighbor heuristics as construction method and 2-opt exchange heuristic as improvement method is developed to obtain same or better solutions obtained by GAMS with less computational time.

Development of a DSP-FPGA-based resolver-to-digital converter for stabilized gun platforms
Zengin, Yasin; Erkmen, İsmet; Department of Electrical and Electronics Engineering (2010)
Resolver, due to its reliability and durability, has been used for the aim of shaft position sensing of military rotary systems such as tank turrets and gun stabilization platforms for decades. Ready-to-use resolver-to-digital converter integrated circuits which convert the resolver signals into position and speed measurements are utilized in servo systems most commonly. However, the ready-to-use integrated circuits increase the dependency of the servo system to hardware components which in turn decrease th...
Modeling and stabilization control of a main battle tank
Karayumak, Türker; Balkan, Raif Tuna; Department of Mechanical Engineering (2011)
In this study, a parametric model for a main battle tank electric gun turret drive system stabilization controller has been developed. Main scope was the study of the muzzle deviation due to barrel flexibility. Traverse and elevation dynamics has been modeled to include the drive-line and barrel flexibilities. Order of the models has been kept large enough to cover the frequencies dominant in the interest scope but at the same time low enough to create a parametric model which can be used in real-time fire ...
Turbulent flow and acoustic predictions over open cavity configurations at transonic speeds
Çoşkun, Seyfettin.; Özyörük, Yusuf; Department of Aerospace Engineering (2019)
In modern military fighters, internal carriage of weapons is vital in terms of high survivability, low observability and aerodynamic performance of the fighter. During store release phases of operation, the aircraft will have to fly with the cavity exposed to free stream conditions. When an aircraft internal weapons bay is exposed to free stream of air, a highly unsteady and complex flow field develops within the cavity. This triggers intense aero-acoustic environment in and around the cavity. Highly complex, un...
Modelling and controller design of the gun and turret system for an aircraft
Mert, Ahmet; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2009)
Gun and gun turret systems are the primary units of the weapon systems of an aircraft. They are required to hit targets accurately during operations. That is why a complete, high precision control of weapon systems is required. This function is provided by accurate modeling of the system and the design of a suitable controller. This study presents the modeling of and controller design for the gun and turret system for an aircraft. For the controller design purpose, first the mathematical model of the system...
Analysis and control of gun barrel vibrations
Büyükcivelek, Fırat; Özgen, Gökhan Osman; Dursun, Tolga; Department of Mechanical Engineering (2011)
Modern battle tanks are equipped with gun stabilization systems using gyro and encoder data to stabilize the gun barrel, although these systems are very sensitive and reliable, these systems assume the gun barrel as a rigid beam, and do not use information from.
