Railguns promise to make space travel and weapons systems much more efficient for the future. I conducted a project to skim the surface of railgun physics and design. I first started by constructing a small railgun as a proof-of-concept. I then delved deeper into the physics of operation by measuring and modeling the magnetic field associated with the operation of the device. The model railgun ...

An effective systems engineering process will provide the framework to enable the complex technical endeavor of railgun system design and development to transition from a set of research projects to a viable acquisition program. The detailed formulation and application of the railgun systems engineering process will be defined by government acquisition agents and the selected private sector con...

The goal of the Cannon Caliber Program is to drive 185 g integrated launch packages to 1,850 d s . Three, fiveround salvos with a firing rate of 5 Hz are intended to defeat specified targets at a range of up to 3 km. After an extensive alternative study, the design team consisting of United Defence FMC/BMY, the Center for Electromechanics at The University of Texas at Austin (CEM-UT) and Kaman ...

We provide an analysis of the nature of emfs induced during the operation of a railgun. The focus here is on the railguns, but the results are applicable to a broad range of similar distributed parameter problems. The main sources of induced emfs are current changes and armature motion. New perspectives are presented. It is shown, for example, that there is no true motional emf in railguns, and...

Abstract Aiming at difficult strain test and unable to accurate for electromagnetic railgun’s special-shaped barrel bore, the testing technology of was studied. According railgun characteristics analysis, back rail insulation support plate are selected as points, FBG(Fiber Bragg Grating) stain sensor is embedded along circumference obtain true value. At same time, in order comparison, The paper...

Many advances in electromagnetic (EM) railgun and power supply technology have been made in recent years. Laboratory experiments with railguns have demonstrated muzzle velocities of 2–3 km/s and muzzle energies 8 MJ. The extension of this technology to the muzzle velocities ( 7500 m/s) and energies ( 10 GJ) needed for the direct launch of payloads into orbit is very challenging, but may not be ...

The excitation pulse current used to drive the railgun needs present very a high magnitude (hundreds of kA) flat-top with low ripple. At present, main method obtain this is increase number capacitive pulsed power supply (PPS) modules. However, utilization and massive volume system would occur method, hampering application railgun. Therefore, optimization technology PPS researched in paper. In o...

Secondary propulsion methods for high-speed hyperloop transportation are sparsely researched. essential to quickly, efficiently, and safely get a pod up its target speed from stationary state. In this article, we propose analyze the feasibility of form electromagnetic (EM) secondary propulsion, called railgun, commonly used in modern-day artillery technology ammunition launching. We assess two ...
