Patent number: 9885244Abstract: A metallic leading edge protective strip adapted to provide impact protection for a leading edge of an airfoil of a turbomachine. The protective strip is formed of a stainless steel or a nickel-based alloy and is denser and provides increased strength and elasticity characteristics as compared to an identical protective strip formed of a titanium-based alloy. The protective strip is particularly suitable for use with composite blades and allows for thinner airfoils, thereby improving engine efficiency.Type: GrantFiled: June 28, 2013Date of Patent: February 6, 2018Assignee: General Electric CompanyInventors: Nicholas Joseph Kray, Dong-Jin Shim, Tod Winton Davis
