DEVELOPMENT OF AN AIRCRAFT COMPOSITE PROPELLER

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.
