GAS TURBINE ENGINE WITH MOUNT FOR LOW PRESSURE TURBINE SECTION

A gas turbine engine (20) includes a very high speed low-pressure turbine (46) such that a quantity defined by the exit area (401) of the low pressure turbine (46) multiplied by the square of the low pressure turbine rotational speed compared to the same parameters for a higher pressure turbine (54)...

Beschreibung
Zusammenfassung:	A gas turbine engine (20) includes a very high speed low-pressure turbine (46) such that a quantity defined by the exit area (401) of the low pressure turbine (46) multiplied by the square of the low pressure turbine rotational speed compared to the same parameters for a higher pressure turbine (54) is at a ratio between about 0.5 and about 1.5. In addition, the lower pressure turbine (46) is mounted with a first bearing (108) mounted in a mid-turbine frame (57), and a second bearing (112) mounted within a turbine exhaust case.
