Future large AF electrical generator channels will be required to operate in parallel to supply single large loads. These channels will be required to use a minimum number of conversion stages to maintain the highest possible efficiency. The EW or other large loads will use power converted directly from the variable speed generator, and only that power required to be 400-Hz will be converted by the V.S.C.F. unit. Redundancy for one generator out condition will be required. The protection and control of the parallel bus will require more sophistication and complexity than the systems presently available. Large rating generators, contactors, and distribution systems will require design effort and test. This report covers a design study to meet the requirements of advanced high power EW systems for aircraft. This report covers the design of a 50 kVA, six-phase generator which is spray oil cooled. The output ratings are 60 kVA at 53 speed, 120 kVA at 60 speed and 410 kVA above 83 speed. The generator maximum design speed is 15,000 rpm.
