Following on the heels of its composite ground-adjustable propellers that are paired with Rotax and Jabiru engines, Sensenich has announced a new two-blade ground-adjustable composite prop for high-speed aircraft such as the Vans RV series or Glasair that use the Lycoming O-320 engine.
The new prop is manufactured using an internal pressure, closed mold system to produce a hollow, one piece blade. The blades also incorporate a patent-pending I-beam construction process that yields repeatable blades with maximum strength, durability and low weight, according to Sensenich.
This propeller features a co-cured bonded stainless-steel leading edge for erosion protection. The two-piece hub is manufactured from aerospace grade aluminum and is either alodined or anodized for corrosion protection.
Sensenich’s Pin Hub System allows pilots to set a broad range of pitches using the system’s index pins to make adjustments. The pilot simply loosens the hub clamping bolts, inserts the desired pitch pin, sets the blades against the pin, torques the mounting bolts and is ready to fly. The entire pitch change process takes less than 5 minutes, Sensenich says.
The blades can be trimmed from the maximum 72-inch diameter to 68-inch diameter. Composite spinners are also available for this propeller to match up to the RV cowling. MSRP is $3750, and various color combinations are available.
