FIELD: aircraft engineering.
SUBSTANCE: every engine set spins mechanically the power transmission gearbox to drive the primary output shaft, hence, the primary rotorcraft rotor at rpm NR. The first engine set comprises the two main engines to be controlled by the first preset rpm NR* of said rpm NR while the second engine set including the auxiliary engine is adjusted by the second preset power magnitude W1* of the second engine set. Besides, the operation of said engine set is controlled by the third preset anticipatory power magnitude W2f* to make the first and second engine sets output the power Ws* required at the level of the primary rotor.
EFFECT: simplified architecture between computers of every engine, optimized power output of every engine.
