Electromagnetic launchers (EMLs) can provide accurate speed control of a projectile compared to gun-powder based alternatives. However large-caliber launchers have several pulse power supply (PPS) modules connected in parallel to reach the required current levels. Determination of the triggering instants of these parallel PPS modules is a crucial part of the launch mechanism. The triggering instants does not only affect the exit velocity but also the forces on the armature which can lead to transition i.e. separation of the armature from the rails. In this study, a triggering sequence optimization method that is faster than other alternatives in the literature and take into account speed-dependent parasitic masses and transition phenomena. Real-coded genetic algorithm (RCGA) and Partical Swarm Optimization (PSO) are used to create bencmarks. 32 capacitive PPS modules with 8 MJ total energy is used. With the achieved accuracy and speed, this study offer: An effective speed control algorithm with several physical constraints.

Electromagnetic simulation and optimization of an electromagnetic launcher Ceylan, Doğa; Keysan, Ozan; Department of Electrical and Electronics Engineering (2018) Electromagnetic launcher (EML) is an electromagnetic accelerator which uses electrical pulse power instead of conventional gunpowder. A large amount of electric current in the pulse waveform flows in the rails and armature. This current creates large magnetic field between rails. As a result of Lorentz force, armature and projectile accelerate. In this study, finite element (FE) model of an EML which includes both pulsed power supply (PPS) circuits with 2~MJ total electrical energy and barrel with 3~m lengt...
Transient Modeling Techniques for the Analysis of Electromagnetic Launchers Tosun, Nail; Keysan, Ozan; Department of Electrical and Electronics Engineering (2021-9-7) Although electromagnetic launchers (EMLs) are better than gun-powder-based launchers, they have to endure severe electrical and mechanical conditions. Therefore, the optimal design and accurate simulations of these devices are essential. The inductance and electromotive force (EMF) variations in the transient, which significantly impact the launch process, are modeled. Moreover, velocity skin effect (VSE) is added to the EML calculations in an effective way. Commercial finite element software cannot solve t...
Optimum placement of high energy inductors for capacitive pulse power supplies GÜNGEN, İBRAHİM; Bostancı, Emine; Department of Electrical and Electronics Engineering (2021-9) Electromagnetic launcher (EML) systems convert electrical energy into mechanical energy. A large amount of energy must be supplied in a short time period to provide the necessary acceleration for the projectile. This type of energy is generally provided by capacitive pulsed power supplies (PPS). Many PPS units are connected in parallel to increase the total energy. Each module of a capacitive PPS includes high energy capacitor, shaping inductor, and semiconductors. The shaping inductors are air-core type in...
Utilization and Optimization of Superconducting Coil Parameters in Electromagnetic Launcher Systems Polat, Hakan; Ceylan, Doga; Keysan, Ozan (2019-06-01) The utilization of external field windings in electromagnetic launchers provides an additional electromagnetic field between the rails of an electromagnetic launcher which increases the Lorentz force acting on the armature in the acceleration direction. However, additional magnetic field created by the conventional copper windings are very limited due to their low maximum current carrying capability. Therefore, using high temperature superconductors (HTS) with a current carrying capability up to 100 A/mm 2 ...
Remote ionization by a short pulse laser beam propagating in the atmosphere Yedierler, Burak (AIP Publishing, 2008-07-01) Self-focusing of high power, short laser pulses is considered for the purpose of identifying physical parameters that allow a remotely controllable ionization in the atmosphere. The propagation equation including diffraction, group velocity dispersion, Kerr nonlinearity and bound electrons effects is derived. A Lagrange density describing the propagation equation depending on a general pulse amplitude is presented for a propagation regime in the absence of ionization and plasma defocusing. Lagrange equation...
