Application technology
Aerial propellers

These benefits include

• mass gain (figure 42);

• possibility of optimizing the material according to the mechanical constraints to be withstood (materials and their characteristics are developed at the same time as the part);

• no corrosion (but beware of galvanic couples when in direct contact with other materials) ;

• higher specific stiffness (Young's modulus/material density), making it possible to design arrow shapes that are impossible to achieve with metallic materials;
