FIELD: engines and pumps.
SUBSTANCE: gas turbine engine comprises of a fan rotatable about the axis, a compressor section, a combustion chamber in fluid communication with the compressor section, and a turbine section in fluid communication with the combustion chamber. The turbine section contains a fan drive turbine and the second turbine. The second turbine is located before the fan drive turbine. The fan drive turbine contains at least three rotors, wherein at least one rotor has a radius (R) of the channel and the effective radius (r) of the rim, and r/R ratio ranges from about 2.00 to about 2.30.
EFFECT: speed changing system is powered by a fan drive turbine to ensure the fan rotation around the axis.
