A main engine electric start system for gas turbine propelled aircraft that employs a low-power AC electrical power system to serve as an independent grid to control the functions of induction-type dynamoelectric machines coupled to the main propulsion engines and APU as a starter or generator.
The claim invention is: 1. A main engine electrical start system for a gas turbine propulsion engine in an aircraft that has a gas turbine engine powered auxiliary power unit (APU), comprising: a battery for supplying direct current (DC) electrical power; a DC to alternating current (AC) power converter for converting at least some of the DC power from the battery to AC power of desired frequency for an independent electrical power grid; a first dynamoelectric machine coupled to the APU for starting the engine of the APU from AC power supplied by the p...
