摘要
Propeller blade manufacturing and operation becomes challenging due to unavoidable casting failures and operational errors. The existing developed patented devices are found to be inefficient in performing reformation of defected blades. Thus, the motive of this research is to develop an innovative approach to overcome the flaws associated with production and operation. Inspired by pin-art boards to form 3-dimensional (3D) shapes, a new model for blade reformation is proposed and examined in this paper. More specifically, the presented innovative device relates to method for reshaping the blade profile to achieve the desired pitch by implementing multiple point loadings over the propeller blades. Along with the device, a hybrid theoretical model was developed, validated and compared with experimental measurements and numerical finite element analyses (FEA). The results have demonstrated its capability in achieving the optimum results under given conditions, signifying its feasibility in smart and advanced manufacturing of blade reformation.
