As the global leader in advanced aircraft propeller design and manufacturing, Hartzell Propeller has been at the forefront of composite propeller blade technology for decades.
A&P Technology is a key supplier of the advanced carbon fiber braids Hartzell uses to layer its composite aircraft propeller blades, providing superior fatigue strength and outperforming alternative composite constructions.
Hartzell Propeller’s composite aircraft propeller blades offer significant strength and performance advantages compared to other designs, such as wood core:
Our carbon fiber is up to 10X stronger than wood, offering uniform strength and integrity.
Laminated wood blades are significantly thicker than Hartzell composite blades. Thicker airfoils produce more drag.
Hartzell’s wedge retention system and stainless steel shanks are much more durable than the alternative aluminum/lag bolt design.
Hartzell structural composite blades are certified for unlimited life and can be repaired in the field or at 30+ Hartzell-approved overhaul shops globally.
In 1978, Hartzell produced the first type-certificated structural composite propeller blade, constructed of compression molded Kevlar/epoxy.
In 2002, Hartzell began the development of our second-generation advanced composite blade (ASC-II), utilizing a resin transfer process and carbon fiber woven braided materials supplied by A&P Technology.
