Claim 0:
1. A gas turbine engine comprising:
a propulsor section including a propulsor having a plurality of blades;
a compressor section including a first compressor and a second compressor;
a geared architecture;
a turbine section including a first turbine and a drive turbine, the drive turbine rotatable as a first spool about an engine longitudinal axis, the first turbine rotatable with the second compressor as a second spool about the engine longitudinal axis, and the propulsor driven by the drive turbine through the geared architecture; and
a power density of greater than or equal to 4.75 and less than or equal to 5.5 lbf/in3, wherein the power density is a ratio of a thrust provided by the engine to a volume of the turbine section, the thrust is sea level take-off, flat-rated static thrust, and the volume of the turbine section is defined by an inlet of a first turbine vane in the first turbine to an exit of a last rotating airfoil in the drive turbine.
