Description
Technical Field
The utility model relates to a combined material stator blade leading edge protective structure belongs to mechanical structure design field, relates to a combined material stator blade leading edge protective structure.
Background
In order to further improve the efficiency of turbofan engines, meet the design requirements of low oil consumption of the engines and improve the market competitiveness of large-scale engines, the weight reduction of the engines becomes one of the main targets of various large-scale engine manufacturers. Due to the advantages of the composite material in the aspects of specific strength and specific rigidity, the composite material is an effective method and means for various large engine manufacturers to improve the thrust-weight ratio of the engine and reduce the weight of the engine. The stator blade is made of composite materials instead of traditional metal materials.
As the front edge of the stator blade made of the composite material is positioned on the windward side, the phenomena of sand and stone striking, cloth layer cracking and the like can occur in the use process of the stator blade, and in order to prevent the front edge of the stator blade from being abraded and the cloth layer from cracking, a front edge protection structure is designed on the front edge of the stator blade, as shown in figure 1. Meanwhile, the chamfer position of the blade root is avoided in the design, and the stripping and falling of the blade root are avoided.

FIG. 2 is a schematic view of the leading edge guard assembly
Wherein: 1-leading edge protection mechanism, 2-stator blade.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 2, the cross section of the composite material stator blade front edge protection structure is a V-shaped structure, the shape of the front edge protection structure is matched with that of the composite material stator blade front edge, the thickness of the front edge protection structure is 0.2-0.3 mm, the width of the front edge protection structure is 10-20 mm, the length of the front edge protection structure is according to the size of the composite material stator blade, the front edge protection structure avoids the blade root chamfer part of the composite material stator blade, and the phenomena of stripping and falling off in the using process can be avoided. The front edge protection structure material is electrolytic nickel and adopts an electroforming process.
The front edge protection structure (1) is bonded on the stator blade (2) through the adhesive, so that the impact resistance and reliability of the stator blade are improved due to the integrity of the front edge protection structure, and the service life of the composite material is greatly prolonged.
