Abstract
"A number of Navy aircraft including P-3, E-2C, and C-130 have electric power systems that use Honeywell generator type 28B95. This generator was rated at 60-kVA per military standard Mil-G-21480A and is capable of providing up to 90-kVA output duringflight. Due to the growth in Avionics, it is desirable to increase the power by 30 to 50%. This must be accomplished within the existing constraints of size, thermal management, and control system to the extent possible. Electrodynamics Associates, Inc.has set up working relationship with Honeywell to obtain the essential technical data for the current design from which the enhancements will be made. Improving the electromagnetic capability through use of better magnetic materials, and using coolingtechniques suggested in Eddie Sines' innovation are the 2 main approaches to increased power capability. Mechanical and structural design, and control and protection circuit compatibility with the existing power will be also considered. A team of expertsis assembled to address all these issues. During the Phase I program, a preliminary generator design layout showing the enhanced design will be prepared. Experimental verification of the cooling scheme and final layout and bill of materials will be done inPhase I Option. This will form the basis of fabrication, and demonstration of the generator during the potential Phase II contract. Most aircraft have 400 Hz. ac elctric power systems. The prop
