Hartzell Propeller is an American manufacturer that was founded in 1917 by Robert N. Hartzell as the Hartzell Walnut Propeller Company. [1] It produces composite and aluminum propellers for certified, homebuilt, and ultralight aircraft. The company is headquartered in Piqua, Ohio. [2]
Hartzell Propeller developed their "Q-tip" propeller used on the Piper PA-42 Cheyenne and several other fixed-wing aircraft types by bending the blade tips back at a 90-degree angle to get the same thrust from a reduced diameter propeller disk; the reduced propeller tip speed reduces noise, according to the manufacturer.

The war ended, and orders dried up. Hartzell began production of its first plane, the FC-1. The plywood plane participated in a race in 1923 which it won. An improved model, the FC-2, won a second race the following year. However, Hartzell found it problematic to compete against his own customers, and to combine production of propellers with ...

PC-6 cabin interior, circa 1960s. The Pilatus PC-6 Porter is a Short Takeoff and Landing (STOL) utility aircraft.The majority of aircraft are powered by a single Pratt & Whitney Canada PT6A turboprop engine, which drives a fully reversible, constant-speed, three-bladed HC-B3TN-3D (or an alternative four-bladed HC-D4N-3P) Hartzell aluminium propeller via a reduction gearbox.
The CS is the budget version, with fewer standard features. [2] Both CS and XLS versions of the DA40 use the Lycoming IO-360-M1A fuel injected engine. The major difference is the choice of propeller, with the CS using a Hartzell two-blade aluminum constant speed prop and the XLS using an MT composite three-blade unit. [3] [4]
A constant-speed propeller is a variable-pitch propeller that automatically changes its blade pitch in order to maintain a chosen rotational speed, regardless of the operational conditions of the aircraft. This is achieved by use of a constant-speed unit (CSU) or propeller governor, which automatically changes the propeller's blade pitch.
