This invention relates to the field of blade crown structure technology and discloses a method for designing the oblique cut angle of crowned blades. By defining the direction and magnitude of the oblique cut angle of the crowned blade and defining evaluation parameters for the rationality of the static design of the crowned blade, simulation models of crowned blades with different sizes and directions of oblique cut angles on the crown contact surface are constructed. Static analysis is performed on the simulation models, and the oblique cut angle and magnitude of the contact surface are determined based on the static evaluation parameters. This invention solves the problems of excessive static stress in the blade due to pre-twist during assembly of crowned blades and crown misalignment due to rubbing.

Reducing the pre-twist angle makes it difficult to ensure that the pre-twist angle tolerance meets requirements during processing and assembly. Using traditional improvement methods requires significant modifications to the blade, limiting engineering applications and affecting other blade performance.
