As the global leader in advanced aircraft propeller design and manufacturing for over a century, Hartzell Propeller has been at the forefront of composite propeller blade technology for decades.

Over the years, our durable and reliable composite blades have become the prop of choice for many of the top aircraft manufacturers. However, we realize some aircraft owners and operators may still have questions about our composite propeller blades:

• What materials does Hartzell use for composite blades?
• What are the advantages of switching from metal propeller blades to true carbon fiber composite?
• What sets Hartzell’s composite propeller blades apart from “wood core” blades?
• What goes into Hartzell’s propeller STC process?

To address these questions (and many more), we’ve provided a comprehensive new resource filled with helpful information for anyone curious about Hartzell’s revolutionary composite propeller technology.

Our latest white paper takes a deep dive into Hartzell’s innovative composite propeller blades, covering:

• The deep history and evolution of Hartzell’s composite propeller technology
• The effort, engineering expertise, and manufacturing precision that goes into making every single Hartzell propeller blade “Built On Honor”
• Hartzell’s rigorous propeller and flight testing processes, including bird strike and lightning strike simulations of our composite blades
• How Hartzell’s composite blades are propelling the future of electric and hybrid-electric aircraft and EVTOLs

To support our customers around the world, we have translations of this white paper available for download in English, French, German, Italian, Portuguese, and Spanish.
