Shock-resistant enhanced turbine engine fan blade

2014 
The invention aims to provide a shock-resistant enhanced turbine engine fan blade; the front edge of the blade can absorb shock energy and reduce damage caused by bird body shock to the front edge of the blade, thus enhancing the shock-resistant effect of the whole blade. For achieving the aim, the shock-resistant enhanced turbine engine fan blade comprises a blade body and a front edge enhancement structure, and is characterized in that the blade body and the front edge enhancement structure are integral parts integrally formed by an additive manufacturing process, the blade body is a metal blade, the material of the front edge enhancement structure adopts a high strength metal material, the front edge enhancement structure comprises an elastic laminar structure extending outwards along the whole longitudinal length direction at the side of the front edge of the blade body, and an intermediate material with affinity for both the material of the metal blade and the front edge enhancement structure is adopted between the front edge enhancement structure and the front edge of the metal blade for transition.
