Cheetah Blade Theory

Energy Return: Curved blade stores impact energy elastically, returning it during push-off. Natural curve (Bezier) mimics biological leg mechanics.

btSoftBody: Treats blade as deformable mesh with spring-like behavior. High stiffness keeps shape while allowing compression/rebound without tearing.

Restitution Coefficient: Return energy / impact energy. Carbon-TPU blades achieve 85-95% in laboratory conditions.

Prosthetic Use: Enables efficient running by converting gravitational/muscular energy into elastic rebound, crucial for sprint athletics.
