New Apex Hubs Now, New Blades Later

Powerfin's new Apex series propeller hubs are manufactured on a Haas VF-4 CNC vertical milling station (shown here), using the same method "used by many aerospace companies to make stator vanes for jet engines and tail rotors for helicopters," Powerfin says. Apex hubs are available in 2-, 3-, 4- and 5-blade configurations.

Composite prop maker Powerfin has developed new Apex series propeller hubs. The new hubs were designed and developed using Solidworks and Mastercam CAD/CAM software, according to Powerfin, and are manufactured "on a brand-new Haas VF-4 CNC vertical milling station," Powerfin notes.

"I bought the machine to finish a 3-year research project, developing a very consistent method of producing blades that is currently being used by many aerospace companies to make stator vanes for jet engines and tail rotors for helicopters," explains Powerfin president Stuart Gort. "Apex hubs result from that research. We can sell them now because the Powerfin propeller blades we currently make can fit the new hubs with only a slight field modification [required]."

Apex hubs are available in 2-, 3-, 4- and 5-blade configurations, and offer "unparalled quality, balance and appearance" the company says. "Gort is now finalizing his work on a new molding process," the company adds, "and hopes to release the first new blade planform before 2003."

Prices for Powerfin's Apex propeller hubs are: 2-blade, $150; 3-blade, $175; 4-blade, $200; and 5-blade, $225. Powerfin hub assemblies include the mounting hardware for the Rotax A, B, C or E gearbox, or the Hirth gearbox, according to Powerfin.
