Apparatus and system for composite fan blade with fused metal lead edge

A fan blade assembly comprising:

• a fan blade airfoil body comprising a length and a leading edge;
• and
• a metal edge comprising:
• an elongate nose member comprising an outside edge, an inside notch and nose body extending therebetween a variable nose length, said inside notch comprising a plurality of fail-fuse elements spaced along a length of said inside notch, said nose length being less proximate said plurality of fail-fuse elements;
• a first integrally-formed edge portion extending away from said nose member along at least a portion of the length of said nose member;
• and
• a second portion edge extending away from said nose member along the at least a portion of the length of said nose member, said first edge portion and said second edge portion forming a notch at the conjunction of said first edge portion, said second edge portion, and said nose.

A fan blade comprising:

• a fan blade root, a fan blade tip, and an airfoil body extending axially therebetween, said airfoil body comprises an axially-spaced leading edge and an axially-spaced trailing edge, said airfoil body comprises a length extending between said fan blade root and said fan blade tip;
• a metal edge comprising:
• an elongate nose member comprising an outside edge, an inside notch and nose body extending therebetween a variable nose length, said inside notch comprising a plurality of fail-fuse elements spaced along a length of said inside notch, said nose length being less proximate said plurality of fail-fuse elements;
• a first integrally-formed edge portion extending away from said nose member along at least a portion of the length of said nose member;
• and
• a second portion edge extending away from said nose member along the at least a portion of the length of said nose member, said first edge portion and said second edge portion forming a notch at the conjunction of said first edge portion, said second edge portion, and said nose.
