The current aircraft noise regulations effected the design of propellers where tip speeds were reduced to meet these regulations. Reduced tip speeds were accomplished by reducing propeller rpm and/or propeller diameter. To retain propeller performance, diameters were increased, or the number of blades increased, respectively. These changes affected the propeller weight drastically. A composite propeller blade has been developed that is significantly lighter than a blade fabricated from aluminum. Additional advantages of the composite blade is strength and maintenance characteristics. Considerable testing was accomplished to demonstrate the strength and fatigue characteristics of the blade.
