Abstract

The invention discloses an adjustable turbine guiding device and a forming method. The device comprises an annular inner ring assembly, an annular outer ring assembly and guiding blades, wherein the inner ring assembly is coaxially sleeved with the outer ring assembly, and the guiding blades are connected between the inner ring assembly and the outer ring assembly. The tail edge end faces of the guiding blades are provided with deformation adjusting seams extending towards the front edges of the guiding blades, the deformation adjusting seams communicate with blade basins and blade backs of the guiding blades, and the deformation adjusting seams are used for enabling the tail edges of one sides of the guiding blades to form angle-adjustable auxiliary wings for adjusting the direction of airflow flowing through the blade basins of the guiding blades and the flow area between every two adjacent guiding blades.

Description

technical field [0001] The invention relates to the field of aviation turbine engines, in particular to an adjustable turbine guide. In addition, the invention also relates to a molding method for the adjustable turbine guide. Background technique [0002] Existing small aero turbine engines have abnormal noises of metal microcracks during the cooling process after each operation. The sound comes from thermal stress release and microcrack propagation during the cooling process of hot end components, which is common in turbine guide cracks. A certain type of engine primary guide vane (such as figure 1 shown) has no cooling air and is prone to ablation due to gas leakage. The cycle life of existing turbine guides is low, mainly because the airfoil is a ruled surface (such as figure 1 As shown), the guide vane connects the outer ring and the inner ring radially and straightly, and the contraction margin is very small. [0003] Small aero turbine engines need to reduce manuf...
