Permanent Magnet Variable Speed Constant Frequency Power Generation System

摘要

The design, development, and aircraft installation of a 60-KVA permanent magnet starter-generator system is presented. The primary objective of this program was to advance the permanent magnet technology and demonstrate that a flexible, reliable, and low-cost starting means can be provided. The electrical system, developed under this program, obviates the use of large air ducts and complicated gearboxes, clutches, and torque converters. Eleven systems were fabricated and flight qualification was completed. The starting capability was demonstrated at Syracuse Air National Guard base and at the General Electric Engine facility in Lynn, Massachusetts. An A-10 aircraft was completely modified at Nellis Air Force base, and the permanent magnet starter-generator was installed. The planned flight test was deferred by Tactical Air Command and, thus, the aircraft was demodified and placed into regular operation.
