Abstract
Compact source of electric power is needed on unmanned combat air vehicles (UCAV) for directed energy weapon (DEW) systems. Electrodynamics proposes integration of high speed induction generator electromagnetics and controls hardware rated at 200 kW, 62000 RPM into a viable system for these applications. The generator produces controlled AC power at a frequency of about 2.1 kHz., which will be stepped up to 30000 plus volts using a high frequency transformer-rectifier-filter unit. The technology integration will be in thermal and mechanical areas. Also the electrical interface issues relating to delivery of high voltage DC power to the HPM weapons are addressed. Innovative approaches proposed are: use of low friction, oil-free air foil bearings for the generator, effective cooling techniques using air or fuel to remove heat, generator packaging in lightweight housing, use of Metglass for stator core to lower iron losses and help thermal management, compact transformer-rectifier-filter design for high voltage output, control of HVDC bus from low potential generator control loop, engine start function, and other protective functions. A team of experts is assembled to carry out the R&D activity. Phase I program will result in hardware designs and drawings for Phase II fabrication and test demonstration.
