PROPFAN ENGINE HAVING TWO OPPOSITELY ROTATING FAN ROTORS |
摘要 |
A propfan engine having two oppositely rotating fan rotors both driven by a low-pressure turbine by way of a drive shaft includes a reversing transmission. The reversing transmission drives one fan rotor, while the other fan rotor is coupled directly to the drive shaft. This construction permits a favorable design of the rotational speeds of the fan rotors and of the turbine and, in comparison to a conventional transmission, requires less space and weight for both fan rotors.
