Sensenich announces TC for carbon fiber ground-adjustable propellers

Sensenich explained in a recent press release, “Propeller options under the [type certificate] range from 72 to 82 inches in diameter to allow for installations on existing aircraft models from 125 to 180 horsepower. Current STCs utilizing the 82 in diameter allow for installation on PA-18-150 models with O-360 engines.”

The propeller’s “advanced carbon fiber monocoque construction” makes it 15 to 20 pounds lighter when compared to fixed-pitch aluminum, and from 30 to more than 50 pounds lighter than constant-speed propeller installations. Its lighter-weight design allows for advantages in useful load as well as “faster throttle and control response, increased maneuvering precision in short fields, inclement weather, and other dynamic situations.”

The ground-adjustable hub system “permits easy, precise, and fast pitch optimization for maximum performance under a variety of operating demands and atmospheric conditions.” The stainless steel erosion shields provide protection from erosion and foreign object debris for “a long, reliable service life.”

Sensenich says the propellers’ “simple installation and operation deliver meaningful and economical improvements without the negative installation cost, service interval, and operating changes associated with constant-speed propeller conversions.”

Sensenich is currently working on additional installation approvals for Piper, Cessna, American Champion, Cub Crafters, Grumman, and other aircraft.

Prices for the carbon fiber, ground-adjustable propellers range from $1,940 to $6,350.
