FIELD: engines and pumps. ^ SUBSTANCE: proposed system comprises first and second power drives and first and second engagement means. First power drive is arranged between high-pressure rotor shaft and first mechanism for them to be drive. First engagement means and second drive are arranged between low-pressure rotor shaft and second mechanisms for them to be driven. Second engagement means are arranged between first drive and second drive to drive second auxiliary mechanisms by high-pressure rotor shaft and take power off at both rotors depending upon operating conditions, or at one of said rotor. Another invention of proposed set relates to method of operating said system comprising disengaging second engagement means with first engagement means engaged. One more invention of said set relates to starting said system with first engagement means disengaged and first engagement means engaged. Note here that first or second mechanisms comprises engine starter. ^ EFFECT: driving auxiliary mechanisms at different rpm under various operating conditions. ^ 6 cl, 6 dwg |
