Propellers and governors, including all accessories, parts, hubs and blades
An aircraft propeller is an aerodynamic device which converts rotational energy into propulsive force creating thrust which is approximately perpendicular to its plane of rotation. The rotational energy can be produced by a piston or gas turbine engine or, in limited applications, by an electric motor. A propeller can be attached directly to the crankshaft of a piston engine, as is the case in many light aircraft, or it might be powered through a reduction gear box (RGB) attached to a piston or jet engine. In this case, the RGB converts the high rotation speed of the engine to one that is more appropriate for propeller operation. Propellers have two or more blades spaced evenly around the hub and are available in fixed pitch or in variable pitch configurations. More sophisticated propeller designs include those of the constant speed, contra-rotating and counter-rotating types.
Hartzell has been the leader in aircraft propeller systems for over 90 years. With 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 modifier. All Hartzell propellers are constant-speed and are available with optional de-ice systems.
