METHOD AND APPARATUS FOR STARTING AN AIRCRAFT ENGINE AND OPERATING A POWER ARCHITECTURE FOR AN AIRCRAFT

摘要

A method and apparatus for starting and operating at least a first starter/generator (S/G) and a second S/G using at least one bi-directional converter and at least one of an AC power source and a first DC power source, including selectively starting at least one of the first S/G or second S/G in an AC start mode or in a DC start mode, and supplying electrical power to a set of electrical loads.

1. A method of starting an aircraft having at least a first turbine engine having a first starter/generator (S/G) and a second turbine engine having a second S/G using at least one bi-directional converter and at least one of an AC power source having an AC power output and a first DC power source having a DC power output, the method comprising:
selectively starting at least one of the first S/G or second S/G in an AC start mode, where the AC power output is supplied to a first bi-directional converter, which converts the AC power output to a second DC power output supplied to the at least one of the first S/G or second S/G, and in a DC start mode, where the DC power output is supplied to start the at least one of the first S/G or second S/G.
