- the obliquely employed outer wall 20 and the stepped pyramidal Recess 5 form a pallet 2, which can be stacked with other pallets is, as long as it is not equipped with items 3.
- Fig. 4 shows a schematic cross-sectional view of a portion of one with blades 9 equipped pallet 2 of the second embodiment of the invention along the Section line B-B of Fig. 2.
- the components with the same functions as in previous Figures are denoted by the same reference numerals and not discussed separately.
- the section line B-B is placed in Fig. 2 so that it cuts the vertical grooves 16, so that the track of the airfoil 9 visible on the sealing surface 17 is and supporting the sealing plate 17 in the vertical grooves 16 and on the Pyramid stages 7 and 8 becomes visible. While the top two blades 9 a axially flowing through flow machine form hollow blades, so that over the Cavity of the blades, a cooling gas can be routed in turbine mode are the lower two pyramid stages are provided for blades in this embodiment, which have no cavity. A comparison of FIGS.
- 3 and 4 also shows that the spatial edge contours 4 adapted bearing surfaces 6 in each pyramid stage are relatively complex designed to both the sealing plate 17 in its approximate rectangular structure as well as the airfoil 9 in its respective Suitably support the edge region and through the invaginated walls 14 to protect against damage.
- Fig. 5 shows a schematic cross-sectional view of a portion of one with blades 9 equipped pallet 2 of the second embodiment of the invention along the Section line C-C of Fig. 2.
- the components with the same functions as in previous Figures are denoted by the same reference numerals and not discussed separately.
- FIG. 5 is a cross-sectional view in the foot area 18 of a blade 9 can be seen.
- the blade feet 12 are from the support surfaces 6 in the foot region 18 are supported by each pyramid stage 7 and 8, that they experience a nearly horizontal orientation.
- the cross-sectional area the blade root 12 is less than the cross-sectional area of the sealing plate 17, which is therefore partially outlined in dashed lines in FIG. 5 in outline.
- the drainage opening 15 is therefore in the range of the lowest sealing plate and at the same time forms the lowest point of the depression 5.
- Fig. 6 shows a schematic cross-sectional view of a portion of one with blades 9 equipped pallet 2 of the second embodiment of the invention along the Section line D-D of Fig. 2.
- the components with the same functions as in before going figures are identified by the same reference numerals and not discussed separately.
- the section line D-D in Fig. 2 is arranged so as to be equipped with blades 5 shows depression in the direction of the longitudinal axis of the blades.
- the bearing surfaces 6 thus support on the one hand the blade root portion 18 and the blade area 19 at their respective edges, with the blade leading edge 10 deeper in each Pyramid level is arranged as the not visible in this figure blade trailing edge.
- the sealing plate of each blade is arranged in vertical grooves 16.
- Fig. 6 also shows with dash-dotted lines a cover plate 26, the top 30 of the pallet 2 can cover.
- This cover plate 26 has in its edge region a collar 27 with a ring projection 28. This ring attachment ensures alignment and sealing the cover plate 26 opposite the top 30 of the pallet 2.
- the collar 27 of the cover plate 26 may serve to populated pallets 2 each other to stack in such a way that the pallet base 29 is centered by the ring lug 28 is supported by the collar 27. In this way, the cover plate 26 provides not only for covering the recesses 5 of the pallet 2, but serves at the same time the stackability of loaded pallets 2.
