Hartzell Propellers

Hartzell Propeller Inc., USA

Without a method of converting the power produced by the engine into useful thrust an aircraft would just be sitting still and creating a lot of noise and not get anywhere. In the past, all kinds of different propeller designs were tried: sometimes flat wooden blades, from one bladed counter weighted to multiple blade models rotating at various speeds.

Variable pitch propellers have a distinct advantage compared to fixed pitch models. This translates into a more fuel efficient, higher performing aircraft with much improved rate of climb and shorter takeoffs for those tight places!

Hartzell Propeller Inc. is the global leader in advanced aircraft propeller design and manufacturing technology. Because of their attention and commitment to propeller driven aviation, we are the supplier of choice for nearly every major aircraft manufacturer. The company traces its history to 1914 when a relationship between Orville Wright and Robert Hartzell led to the manufacture of the first Hartzell airplane propeller in 1917. The company’s founding principle of “Built on Honor” has been central to corporate values from the very beginning.

Aviation Products

Hartzell has been the leader in aircraft propeller systems for over 90 years. They have over 400 different blade designs available which can be configured in hubs with 2- through 6-blades to provide optimal performance for the aircraft designer builder. All Hartzell propellers are constant speed and are available with optional de-ice systems.

The propellers are constructed from various materials, but the primary structural components in the hub system are high strength aluminum alloy or steel forgings. Blades are made from high strength aluminum alloy forgings or advanced composite materials (Kevlar® or carbon fiber).

Piston & Turboprop aircraft

Hartzell Mooney Propellers

For these aircraft Hartzell features an extensive selection of aluminum and composite propellers which are the latest in state-of-the-art manufacturing for piston powered aircraft.


As the company offers a wide variety of Hartzell propellers, they also carry an extensive selection of Hartzell spinners, which integrate the propeller to the aircraft. These spinners are available in a variety of sizes and can be made from spun aluminum or composite materials and are designed and manufactured to the highest specifications to ensure safety and reliability for the customer.


As Hartzell only is manufacturing constant speed propellers, there is the need to complement that product with an exceptional regulator or governor. These have the following specifications: normal / high capacity, feathering, synchronizing and synchro-phasing for multi-engine aircraft.
