VARIABLE PITCH FAN FOR GAS TURBINE ENGINE AND METHOD OF ASSEMBLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine engine with a smaller variable pitch fan that can generate larger amounts of thrust.SOLUTION: A gas turbine engine is provided. The gas turbine engine includes a core and a variable pitch fan arranged in flow communication with the core. The variable pitch fan has a disk and at least nine fan blades coupled to the disk for rotation together with the disk. The gas turbine engine further includes a rotatable nacelle covering the disk such that the engine has a fan hub radius ratio between about 0.1 and about 0.4.SELECTED DRAWING: Figure 1
