A turbofan engine includes two oppositely rotating fan rotors which are arranged upstream of the core engine, and has a booster with two contra-rotating coaxial rotors. The radially exterior booster rotor is arranged between the rearward fan rotor and the low-pressure turbine in a torque-transmitting manner. The gearless construction permits an almost uniform loading of the low-pressure shafts.

Turbofan engine having a contrarotating low-pressure compressor

A propfan turbine engine having a reduction gearing for the propfan rotors is provided with a lubricating system of its own for the reduction gearing, the system being arranged axially between the gas turbine and the reduction gearing and formed as an annular assembly surrounding a drive shaft from a gas turbine to the reduction gearing. Cooling air is supplied to the lubricating system as a location which will not interfere with the supply of air to the compressor of the gas turbine.
