High pressure turbine disk
WebHigh Pressure Turbine. Figure 1 . High pressure turbine: The high pressure (HP) turbine (see Figure 1) is the first main engine turbine to receive steam from the main steam system. It is designed to efficiently extract work out of high pressure steam. The HP turbine is a pressure-velocity compounded, single axial flow, non-condensing impulse ... Webin the low pressure turbine cavity damaged the bolts holding the stage 1 low pressure turbine rotor disk and stage 2 low pressure turbine rotor disk together. The bolts failed at high engine thrust and the stage 1 low pressure turbine disk separated from the low pressure turbine rotor assembly, overped, and burst.
