摘要： A blade for a gas turbine engine includes an airfoil (80) having a leading edge (82), a pressure side (84), a suction side (86) and a trailing edge (88) that extend to a tip (89) of the airfoil (80); a leading edge cavity (90) located within the airfoil (80); at least one main body cavity (92) located within the airfoil (80); pressure side skin core passages (94) located within the airfoil (80); suction side skin core passages (96) located within the airfoil (80), the at least one main body cavity (92) being fluidly isolated from the pressure side skin core passages (94) and the suction side skin core passages (96) and the at least one main body cavity (92) being located between the pressure side skin core passages (94) and the suction side skin core passages; a trailing edge feed cavity located within the airfoil (80); and a tip plenum (100) located proximate to the tip (89) of the airfoil (80), the tip plenum (100) being fluidly coupled to the at least one main body cavity (92), wherein the tip plenum (100) is located above the pressure side skin core passages (94) and the trailing edge feed cavity and extends to the trailing edge of the airfoil (80).

摘要： Method for determining mechanical degradation of parts of a centrifugal pump having a fluid inlet, an impeller, and a fluid outlet, comprising:
calculating at least one of a wear-ring clearance effect and an impeller wear effect where calculating said wear-ring clearance wear effect uses:
using measurements of (200) an actual pump flow rate Qp and actual pump power Pwp (121), calculating (210) an internal flow rate of the pump QpPwp (132), calculating (220) the mechanical power PwQp (131) that should be used if the pump worked as specified in the theoretical curve, calculating (250) a difference between a theoretical Head and an internal Head Hpth- HpPwp to obtain the loss of Head due to the wear-ring clearance;
and where calculating said impeller wear effect is done using:
measuring (300) an actual input pressure pin, an actual output pressure pout and an actual pump power Pwp, calculating (310) a theoretical flow rate QpPwp corresponding to the measured mechanical power Pwp (132), calculating a theoretical Pump Head HpPwp, calculating (330) the actual Pump Head Hp from the actual input pressure pin, and the actual output pressure pout and a pumped fluid density, calculating a difference between said theoretical pump head and said actual pump Head HpPwp - Hp to obtain the loss of head due to the impeller wear.
