A dual rectangular tooth with a turbine blade trailing edge panel

The present invention discloses a pair of rectangular tooth board mating edge of the turbine blade, comprising blades and a bead plate; mounting a blade edge of each bottom plate; rectangular side edges of a rectangular plate tooth. Each turbine blade is divided into two groups, each of two blades disposed opposite edges of plates mounted to opposite sides of the rectangular tooth intermeshing, two opposite side edges of the flat plate structure; edges of each plate pair consisting of the planar structure and a planar structure adjacent groups cooperating edge of the plate, a plane contact. Advantageously, by the engagement between the toothed plates are rectangular, to increase the rigidity of the blades, to improve the natural frequency of the blade; planar contact edges of different groups during blade vibration plate, each other by friction between the vibration energy is absorbed, a damping effect.
