Twin-spool turbine for aircraft, has electrical generators driven through differential gear having two planet wheels driven by high and low pressure rotor shafts of high and low pressure bodies, and planet gear driven by wheels

摘要

The turbine has electrical generators driven through a differential gear (30) having two planet wheels (31`, 32`) driven by high and low pressure rotor shafts (1, 2) of high and low pressure bodies. The wheels drive a planet gear (33) mounted in a casing (36). Transmission ratios between respective shafts and wheels are such that distribution of power between the bodies lies between 80 by 20 percent.
