Hartzell Constant Speed Propellers
New Constant-Speed Propellers
DescriptionVan's Aircraft has an OEM agreement with the Hartzell Propeller Company which enables us to offer brand new constant-speed propellers for RV aircraft at very attractive prices. This agreement requires that propellers purchased from Van's be used in RVs.
These props weigh 50 to 55 lbs. They require a "constant-speed" cowl. Since mid 1994, this has been the standard cowl shipped with all kits. These props go to a flat pitch (take-off position) with no oil pressure and go to maximum pitch with maximum control pressure, which is supplied by an engine driven prop governor.
The C2YR hub propellers for the (I)O-360 engines are the newer "blended airfoil" aluminum blade design. The 74" blade diameter propellers are applicable to the "A" or tricycle gear aircraft except for the RV-8, while the 72" blade diameters are recommended for the tailwheel aircraft to ensure adaquate ground clearance.
A Hartzell three blade composite propeller is available for the RV-10. Must be bought with the polished aluminum spinner, as the Van's kit spinner will not work with a three blade propeller.
A 74" two blade composite propeller for the (I)O-360 180/200hp engines is also available. This prop has an extended hub for blade/cowl clearance, and therefore the kit spinner will not work. Builders who choose this prop must also use the appropriate Hartzell spinner.
We have no performance data to compare these composite propellers with the aluminum blended airfoil type.
No testing has been done that suggests any performance difference between the 72" and 74" propellers.
Please review propeller application restrictions on the Hartzell website.
ALL HARTZELL PROPS INCLUDE BOLTS AND MOUNTING HARDWARE.
BECAUSE OF THE O.E.M. AGREEMENT, THESE PROPELLERS MUST BE ORDERED IN WRITING.
If a new propeller and an Experimental Lycoming engine are ordered at the same time, Van's can offer a special "package" discount on the combination.
