Abstract:
A gas turbine engine has a fan section including a fan, a compressor section including a low pressure compressor and a high pressure compressor, a turbine section including a low pressure turbine and a high pressure turbine, and a gear reduction. The low pressure compressor and the low pressure turbine have a number of blades in each of at least one of a plurality of blade rows. The blades are rotatable at least some of the time at a rotational speed in operation. The number of blades in at least one row and the rotational speed are such that the following formula holds true for at least one row of the compressor rotor turbine: (number of blades×rotational speed)/60 s≥5500 Hz, and the rotational speed is in revolutions per minute.

Claim (Index 24):
The gas turbine engine as set forth in  claim 21 , further comprising:\n a core flowpath and a mid-turbine frame arranged between the low pressure turbine and the high pressure turbine, the mid-turbine frame having airfoils positioned in the core flowpath, and the mid-turbine frame supporting at least one bearing system; wherein the low pressure compressor includes three stages, the low pressure turbine includes a greater number of stages than the low pressure compressor, the high pressure turbine includes two stages, and the high pressure compressor includes a greater number of stages than the low pressure turbine; wherein the fan has a low corrected fan tip speed of less than 1150 ft/second; and wherein the formula results in a number greater than or equal to 5500 Hz for all of the rows of the low pressure compressor and for all of the rows of the low pressure turbine.
