DEVICE FOR MECHANICAL POWER TALE-OFF BETWEEN HIGH-PRESSURE AND LOW-PRESSURE SHAFTS OF TWO-SHAFT GAS TURBINE ENGINE Russian patent published in 2010 - IPC F02C7/36 

FIELD: engines and pumps.

SUBSTANCE: two-shaft gas turbine engine auxiliary mechanism driving device comprises low-pressure shaft and high-pressure shaft, differential mechanism with first and second input shafts and output shaft, and box of drives with common driven shaft. Auxiliary mechanisms are fitted on drive box. First input shaft engages via selective coupling with either low-pressure shaft or high-pressure shaft. Second input shaft engages with high-pressures shaft, while output shaft engages with driven shaft of drive box.

EFFECT: possibility to take off power at low-pressure shaft and maintain drive box rotation in rpm range compatible with mechanisms installed therein.
