The aircraft (1) has two main engines (11,12) for driving a main gearbox, which in turn drives rotation of a rotary wing (2). A main regulation system (15) regulates each main engine upon application of a variable set point. The aircraft also has a secondary engine (21) also capable of driving the gearbox. A secondary regulation system (25) regulates the secondary engine upon application of a constant set point independent from the main regulation system. An independent claim is also included for a method of driving rotation of a main gearbox driving rotation of a rotary wing of an aircraft. |
