Turbine guider blade made of SiCSiC composite material

The utility model discloses a turbine guider blade made of SiCSiC composite materials. The turbine guider blade comprises an upper edge plate component, a blade body component and a lower edge plate component which are sequentially connected from top to bottom. The upper edge plate component, the blade body component and the lower edge plate component each comprise a silicon carbide fiber framework, a silicon carbide base body arranged on the silicon carbide fiber framework and an interface transition layer arranged between the silicon carbide fiber framework and the silicon carbide base body. The allowable temperature of the blade is improved by about 200 DEG C, and the cooling air flow is reduced by about 70% under the same turbine front temperature of the engine, so that the thrust and the efficiency of the engine are improved. 本实用新型公开了一种SiCSiC复合材料涡轮导向器叶片，包括由上至下依次连接的上缘板部件、叶身部件和下缘板部件；上缘板部件、叶身部件和下缘板部件分别包括碳化硅纤维骨架，设于碳化硅纤维骨架上的碳化硅基体，以及设于碳化硅纤维骨架与碳化硅基体之间的界面过渡层。提高了叶片的许用温度约200℃，在同样的发动机涡轮前温度下，减少冷却空气流量70％左右，使发动机推力和效率得
