摘要： PROBLEM TO BE SOLVED: To reduce a whole flow mixing loss region and a leading edge leak-out flow to improve efficiency by using a discontinuous part to form a flow balancing slot. SOLUTION: Covers 20, 40 of airfoils 30, 50 having opposing positive pressure sides 31, 51 and negative pressure sides 32, 52 of a rotatable turbine stage 10 to prevent fluid Fsc from crossover-flowing from the positive pressure side 51 of a leading edge airfoil 50 to the negative pressure side 32 of a trailing edge airfoil 30 are provided. The covers 20, 40 include positive pressure and negative pressure side edge portions 21, 22, 41, 42, one of which having a shape that is discontinuous relative to that of a complementary edge of the negative pressure and positive pressure side edge portions 21, 22, 41, 42 of aft covers 20, 40 of corresponding ones of the trailing edge and leading edge airfoils 30, 50, respectively. The flow balancing slot 45 is formed by this discontinuous part. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce shroud temperature and enhance bucket life.SOLUTION: A seal system between a row 112 of buckets supported on a machine rotor and a surrounding stationary casing or stator includes a tip shroud 114 secured at radially outer tips of each of the buckets, the tip shroud formed with a radially-projecting rail 116. A cellular seal structure 120 is supported in the stationary stator in radial opposition to the tip shroud and the rail. The seal structure 120 has an annular array of individual cells formed to provide continuous, substantially horizontal flow passages devoid of any radial obstruction along substantially an entire axial length dimension of the cellular seal structure to prevent flow about the tip shroud from turning radially inwardly.
