Abstract
A method of starting an aircraft having at least a first starter/generator (S/G) and a second S/G using at least one inverter/converter and at least one of an AC power source and a first DC power source, the method includes selectively starting at least one of the first S/G or second S/G in an AC start mode and in a DC start mode.
Claims10
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 inverter/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 inverter/converter, which converts the AC power output to a second DC power output supplied to a second inverter/converter, which inverts the second DC power output to a second AC power output, which is 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 the inverter/converter, which inverts the DC power output to a second AC power output, which is then supplied to the at least one of the first S/G or second S/G.
