Abstract: A metallic leading edge protective strip (12) adapted to provide impact protection for a leading edge of an airfoil of a turbomachine. The protective strip (12) 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 (10) and allows for thinner airfoils, thereby improving engine efficiency. Corresponding airfoil and method of producing such airfoil are also provided.

Abstract: According to present embodiments or aspects thereof, a composite booster spool (31) with separable composite blades (50) is provided. The blades (50) are inserted radially from within the inner circumference of the spool (31) and extend outwardly through the spool. The system provides a reduced weight assembly as compared to prior art metallic or composite/metallic combination systems. Additionally, the blades are separable which results in a more field-serviceable assembly over a fully integral system wherein the blades and spool are integrally formed from composites or combination of metal and composites.
