First Claim
Patent Images
1. A system for multi-engine coordination of gas turbine engine motoring in an aircraft, the system comprising:
- a controller operable to determine a motoring mode as a selection between a single engine dry motoring mode and a multi-engine dry motoring mode based on at least one temperature of a plurality of gas turbine engines and initiate dry motoring based on the motoring mode.

9. A system of an aircraft, the system comprising:
-
a compressed air source operable to supply compressed air; a first engine system comprising a first gas turbine engine, a first air turbine starter, a first starter air valve, and a first controller operable to command the first starter air valve to control delivery of the compressed air to the first air turbine starter during motoring of the first gas turbine engine; a second engine system comprising a second gas turbine engine, a second air turbine starter, a second starter air valve, and a second controller operable to command the second starter air valve to control delivery of the compressed air to the second air turbine starter during motoring of the second gas turbine engine; and at least one engine control interface operable to determine a motoring mode as a selection between a single engine dry motoring mode and a multi-engine dry motoring mode based on at least one temperature of the first and second gas turbine engines and initiate dry motoring based on the motoring mode. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for multi-engine coordination during gas turbine engine motoring, the method comprising:
-
receiving, by a controller, at least one temperature of a plurality of gas turbine engines; determining, by the controller, a motoring mode as a selection between a single engine dry motoring mode and a multi-engine dry motoring mode based on the at least one temperature of the plurality of gas turbine engines; and initiating dry motoring based on the motoring mode. - View Dependent Claims (16, 17, 18, 19, 20)
