Shape Preserving In Aerodynamic Product Profiles Using Geometric Design Modelling

Shinkansen bullet train was inspired by Kingfisher beak which the nose shape design of the bullet train is streamlined, and influenced the aerodynamic consumption. Long nose shape design lead to high production cost, material usage and longer building time. Therefore, the high-profile curve design w...
