Definitions

  • the invention relates to a compressor blade for a compressor, which has along a main axis a blade root, a platform region and a subsequent blade profile with a profile tip, which blade profile of a convex suction side wall and the suction side wall opposite concave pressure side wall is formed, which surfaces, based on a flow medium, extending from a leading edge to a trailing edge and between which a profile centerline runs centrally, wherein at the profile tip a transverse to the main axis end face is arranged, on which a sealing lip extends at least partially from the leading edge to the trailing edge.
  • a compressor blade having such a blade profile is known.
  • the free end of the blade profile has an end face on which runs a lip-like rib in the region of the suction side of the blade profile from a leading edge to a trailing edge.
  • the rib of the compressor blade serves as a sealing element in the operation of the compressor to reduce the peak gap losses in the compressor which occur between the blade tip and the confinement of the compressor duct.
  • the object of the invention is therefore to provide a low-cost compressor blade, without reducing the sealing effect of the sealing lip. Moreover, it is an object of the invention to provide a compressor for this purpose.
  • the task related to the compressor blade is achieved by the features of claim 1 and the object directed to the compressor is solved by the features of claim 5.
  • the invention proposes that the sealing lip runs at a distance from the suction side wall and from the pressure side wall along the profile center line.
  • the position of the sealing lip on the profile tip is changed in such a way that error-prone and cost-intensive production steps are eliminated. Due to the newly selected position of the sealing lip their production can be carried out by means of a three-axis milling cutter. In addition, manual post-processing is no longer required.
  • the manufacturing process is shortened because the new sealing lip geometry can be made faster due to its simplicity. Furthermore, the omission of manual post-processing leads to a significantly higher process reliability.
  • the sealing lip has a suction-side side surface and a pressure-side side surface, which run parallel to the main axis, this can be made particularly simple and thus cost-effective.
  • the sealing lip reduces the tip gap losses across the profile tip.
  • the side surfaces of the sealing lip are connected to each other by means of a rubbing surface, which rubbing surface is perpendicular to the radius of the rotor of the compressor.
  • a cylindrical gap can be formed between the housing or hub components and the compressor blade, which reduces the gap losses.
  • the compressor blade according to the invention can be used in the same way advantageous as a blade as well as a vane.
  • the object directed to the compressor is achieved by the features of claim 5.
  • the solution suggests that the compressor is equipped with at least one compressor blade according to one of claims 1 to 4.
  • the advantages of the compressor correspond to the advantages of the compressor blade.
  • FIG. 1 shows a gas turbine 1 with a rotor 5 rotatably mounted about a rotation axis 3.
  • the gas turbine 1 has an intake chamber 7, a compressor 9, a toroidal annular combustion chamber 11 and a turbine unit 13.
  • Both in the compressor 9 and in the turbine unit 13 guide vanes 15 and blades 17 are each arranged in rings.
  • a blade ring 19 is followed by a blade ring 21.
  • the rotor blades 17 are fastened to the rotor 5 by means of rotor disks 23, whereas the stator blades 15 are fixedly mounted on the housing 25.
  • Wreaths 21 of guide vanes 15 are likewise arranged in the turbine unit 13, which, viewed in the direction of the flow medium, is followed by a ring of rotor blades 17.
  • the respective blade profiles of the guide vanes 15 and of the rotor blades 17 extend radially in an annular flow channel 27.
  • air 29 is sucked through the intake manifold 7 and compressed by the compressor.
  • the compressed air is guided to the burners 33, which are provided on a ring lying on the annular combustion chamber 11.
  • the compressed air 29 is mixed with a fuel 35, which mixture in the annular combustion chamber 11 is burned to a hot gas 37.
  • the hot gas 37 flows through the Flow channel 27 of the turbine unit 13 to guide vanes 15 and blades 17 over.
  • the hot gas 37 relaxes on the blades 17 of the turbine unit 13 to perform work.
  • the rotor 5 of the gas turbine 1 is set in a rotational movement, which serves to drive the compressor 9 and to drive a work machine, not shown.
  • the compressor blade 50 has a blade root 55, a platform region 27 with a platform 59 and a blade profile 61 along a main axis 53.
  • the blade profile 61 is flowed around during operation of the compressor 9 of air 29, which the blade profile 61 on a leading edge 63 on and flows from a trailing edge 65.
  • the blade profile 61 is formed by a pressure side wall 67 and a suction side wall 69.
  • a profile center line 71 which has at each point of its course a vertical, which perpendicular 74 both the suction side wall 69 and the pressure side wall 67 intersects.
  • a first distance A between the intersections of the vertical 74 with the profile center line 71 and the pressure side wall 67 with the vertical 74 is identical to a second distance B, which between the intersections of the profile center line 71 with the vertical 74 and the suction side wall 69 with the vertical 74, is present.
  • the blade profile 61 on its side facing away from the platform 59 profile tip 72 on an end face 73 on which a sealing lip 75 is arranged.
  • the sealing lip 75 is narrower than the blade profile 61, extending from the leading edge 63 to the trailing edge 65 and extends along the profile center line 71, ie at a distance between the contour of the suction side wall 69 and the pressure side wall 67th
  • the sealing lip 75 has a first side surface 77 facing the pressure side wall 67 and a second side surface 79 facing the suction side wall 69.
  • the curved side surfaces 77, 79 of the sealing lip 75 are parallel to the main axis 53 and also parallel to the profile center line 71, whereas the suction side wall 69 of the blade profile 61 and the pressure side wall 67 of the blade profile 61 inclined for aerodynamic reasons, i. obliquely, to the main axis 53 run. Compared with a blade of the prior art, a simplified production of the sealing lip 75 can thereby be achieved.
  • a rubbing surface 81 also called squealer edge, connected to each other, which abraded surface 81 is perpendicular to the radius of the rotor 5 of the compressor 9.
  • FIG. 3 shows a detailed view of a squealer according to the invention. It can be clearly seen that the sealing lip 75 runs centrally between the suction side wall 69 and the pressure side wall 67 from the leading edge 63 to the trailing edge 65 with side surfaces 77, 79 aligned parallel to the main axis 53 and the profile center line 71.
  • the new geometry and position of the sealing lip 75 eliminates error-prone and costly manufacturing steps. As a result, both the manufacturing costs and the reject rate of the manufactured compressor blades 50 can be reduced. A deterioration of the top gap losses across the radial gap between the compressor blade 50 and the inner housing does not occur, as well as flow losses due to the insignificantly reduced aerodynamically effective profile surface.
