Abstract

The invention discloses an adjustable turbine guider and a forming method, comprising: an annular inner ring assembly, an annular outer ring assembly coaxially sleeved outside the inner ring assembly, and an inner ring assembly and an outer ring assembly. For the guide vane between the components, the trailing edge end surface of the guide vane is provided with a deformation adjustment seam extending toward its leading edge. The deformation adjustment seam connects the vane pot and the blade back of the guide vane. The deformation adjustment seam is used to make the trailing edge on one side An adjustable aileron with an adjustable angle is formed to adjust the airflow direction flowing through the vane basin of the guide vane and the flow area between two adjacent guide vanes.

Description

technical field [0001] The present invention relates to the field of aero-turbine engines, in particular, to an adjustable turbine guide. In addition, the present invention also relates to a molding method for molding an adjustable turbine guide. Background technique [0002] The existing small aero-turbine engine has abnormal sound of metal micro-cracks during shutdown and cooling after each operation. The sound comes from the release of thermal stress and the expansion of micro-cracks during the cooling process of the hot-end components, which are commonly found in turbine guide cracks. The first-stage guide vanes of a certain type of engine (such as figure 1 shown) without cooling air and prone to ablation due to gas leakage. The cycle life of existing turbine guides is low, mainly due to the ruled surface of the airfoil (such as figure 1 shown), the guide vanes connect the outer ring and the inner ring in a straight line radially, with a small shrinkage margin.
