FIELD: engines and pumps.
SUBSTANCE: when stopping an engine, the electric power generated by the rotation of a low-pressure rotor shaft is transmitted to electric motor-generator of high-pressure rotor shaft to create additional acceleration which provides the ratio of the duration of the high-pressure rotor shaft running-out to the duration of the low-pressure rotor running-out equal to 1.5…6.0.
EFFECT: excluding effect of dragging of high-pressure rotor shaft when shutdown.
