cooled blades, spatial accuracy, thickness variation, core buckling, naturally twisted rod, core deflection, core twist angle, core deformation in a casting, thermal expansion, shell-corecasting system, deformation processes during blade formationAbstract
The article presents the equations of deflection and the angle of twist of the rod depending on the geometric characteristics of the rod, the conditions for its fixing, the force factors and the characteristics of the blade material and shape. The resulting equation is a theoretical basis for the study of the formation of geometric parameters, both the blade itself and the form elements (core, shell) at various technological stages.References
