Development of a 9 MJ Electric Gun System and Range
The Task B effort officially began in 1986 with the announcement of the Electromagnetic Gun Weapon System Program (EMGWS). The goal of this subtask was to demonstrate a single shot EM gun suitable for establishing parameters ...
Development of a simple nonlinear switched reluctance motor model using measured flux linkage data and curve fit
This paper presents the formulation and simulation of a simple nonlinear switched reluctance motor (SRM) model. The model formulation is developed by first measuring the motor's flux linkage. A suitable 3 dimension shape ...
Hydrodynamic bearing applications of micro-electro-mechanical systems
Microdynamical systems have been studied for a number of years, with concentration on sensors and, more recently, actuators. Only limited work has been completed on integrating microdynamical components into systems that ...
Pulsed Rotating Machine Power Supplies for Electric Combat Vehicles
As technology for hybrid-electric propulsion, electric weapons and defensive systems are developed for future electric combat vehicles, pulsed rotating electric machine technologies can be adapted and evolved to provide ...
Control System for Inside-Out Configuration Magnetic Bearings
The University of Texas Center for Electromechanics (UT-CEM) in association with the Texas A&M Vibration Control Lab (TAMU-VCL) has developed an active magnetic bearing control system for use in a 5 MW, 25 MJ, 20,000 RPM ...
Homopolar Welding: Results of Five Years of Research
Homopolar welding (HPW) is a high speed electric resistance forge welding process being developed for single shot girth welds proposed for the J-Lay pipelaying technique in deepwater. The homopolar welding technique uses ...
Inside-Out Configuration Active Magnetic Bearing Actuators
The University of Texas Center for Electromechanics (UT-CEM) has designed active magnetic bearing actuators for use in a 5 MW flywheel alternator with a 700 lb (318 kg), 20,000 rpm rotor, under the sponsorship of the ...
Electromagnetic Powder Deposition
Advances in homopolar welding of API linepipe for deepwater applications
The University of Texas at Austin Center for Electromechanics is conducting a research program to study homopolar welding of line pipe for J-Lay applications. In 1995, the third year of the five year research program, ...
Multi-Shot Power Supply Using Capacitors for an Electromagnetic Powder Deposition (EPD) Gun
The Department of Defense (DoD) and commercial entities are dependent on chemical plating and coating processes to replace worn or eroded material on damaged parts. Air Force Logistics Centers have been forced to consider ...
