Propeller Owner’s Manual 340 INTRODUCTIONPage 1-3 Aug/13 1. Purpose cAution: KEEP THIS MANUAL WITH THE PROPELLER OR THE CRAFT UPON WHICH IT IS INSTALLED AT ALL TIMES. THE LOgBOOK RECORD WITHIN THIS MANUAL MUST BE MAINTAINED, RETAINED CONCURRENTLy, AND BECOME A PART OF THE CRAFT AND ENgINE SERvICE RECORDS. A. This manual supports Hartzell Propeller Inc. Constant Speed and Constant Speed Feathering Compact series propellers with composite blades or metal blades installed on Wing-In-ground-effect (WIg) craft. (1) The purpose of this manual is to enable qualified personnel to install, operate, and maintain a Hartzell Propeller Inc. Constant Speed or Constant Speed Feathering Propeller. Separate manuals are available concerning overhaul procedures and specifications for the propeller. (2) A sample propeller and blade model designation is included in the Description and Operation chapter of this manual. 1 Parentheses shown in the propeller model designations in this or other Hartzell Propeller Inc. publications indicate letter(s) and/or number(s) that may or may not be present because of different configurations permitted on the various craft installations. 2 Definitions of propeller model designations and further details of letters that may be present are shown in the Description and Operation chapter of this manual. Propeller Owner’s Manual 340 INTRODUCTIONPage 1-4 Aug/13 2. Craft or Engine Modifications A. Propellers are approved vibrationwise on craft and engine combinations based on tests or analysis of similar installations. this data has demonstrated that propeller stress levels are affected by craft configuration, airspeed, weight, power, engine configuration and flight maneuvers. Craft modifications that can affect propeller stress include, but are not limited to: aerodynamic changes ahead of or behind the propeller, realignment of the thrust axis, increasing airspeed limits, and increasing or decreasing weight limits (less significant on piston engines). B. Engine modifications can also affect the propeller. The two primary categories of engine modifications are those that affect structure and those that affect power. An example of a structural engine modification is the alteration of the crankshaft or damper of a piston engine. Any change to the weight, stiffness or tuning of rotating components could result in a potentially dangerous resonant condition that is not detectable by the pilot. Most common engine modifications affect the power during some phase of operation. Some increase the maximum power output, while others improve the power available during hot and high operation (flat rating) or at off-peak conditions. Examples of such engine modifications include, but are not limited to: changes to the compressor, power turbine or hot section of a turboprop engine; and on piston engines, the addition or alteration of a turbocharger or turbonormalizer, increased compression ratio, increased RPM, altered ignition timing, electronic ignition, full authority digital electronic controls (FADEC), or tuned induction or exhaust. C. All such modifications must be reviewed and approved by the propeller manufacturer before obtaining approval on the craft. Propeller Owner’s Manual 340 INTRODUCTIONPage 1-5 Aug/13 3. General A. Personnel Requirements (1) Inspection, Repair, and Overhaul (a) Compliance to regulatory requirements established by the applicable certification agency is mandatory for anyone performing or accepting responsibility for any inspection and/or repair and/or overhaul of any Hartzell Propeller Inc. product. (b) Personnel performing maintenance are expected to have sufficient training and certifications (when required by the applicable certification agency) to accomplish the work required in a safe manner. B. Maintenance Practices (1) The propeller and its components are highly vulnerable to damage when they are removed from the engine. Properly protect all components until they are reinstalled on the engine. (2) Never attempt to move the craft by pulling on the propeller. (3) Use only the approved consumables, e.g., solvents, lubricants, etc. (4) Safe Handling of Paints and Chemicals (a) Always use caution when handling or being exposed to paints and/or chemicals during propeller overhaul and maintenance procedures. (b) Before using paint or chemicals, always read the manufacturer’s label on the container and follow specified instructions and procedures for storage, preparation, mixing, and application. (c) Refer to the product’s Material Safety Data Sheet (MSDS) for detailed information about physical properties, health, and physical hazards of any chemical. (5) Observe applicable torque values during maintenance. Propeller Owner’s Manual 340 INTRODUCTIONPage 1-6 Rev. 1 Aug/14 (6) Approved paint must be applied to all composite and metal blades. Aluminum blades must have corrosion protection applied, follwed by paint. For information about the application of paint, refer to the Maintenance Practices chapter of this manual. Operation of blades without the specified finishes is not permitted. (7) Before installing the propeller on the engine, the propeller must be static balanced. New propellers are statically balanced at Hartzell Propeller Inc. Overhauled propellers must be statically balanced by the overhaul facility before return to service. (a) Dynamic balance is recommended, but may be accomplished at the discretion of the operator, unless specifically required by the craft or engine manufacturer. 1 Perform dynamic balancing in accordance with the Maintenance Practices chapter of this manual. 2 Additional procedures may be found in the applicable maintenance manual. (8) As necessary, use a soft, non-graphite pencil or crayon to make identifying marks on components. (9) As applicable, follow military standard NASM33540 for safety-wire, safety cable, and cotter pin general practices. Use 0.032 (0.81 mm) safety wire unless otherwise indicated.

Description of Propeller and Systems A. System Overview The propellers included in this manual are constant speed, single-acting, hydraulically actuated propellers. These propellers are designed for use with reciprocating engines. A constant speed propeller system is controlled by an engine speed sensing device (governor) to maintain a constant engine/propeller RPM by changing blade angle. The governor uses an internal pump that is driven by the engine. This pump increases engine oil pressure for supply to the propeller. Engine speed sensing hardware within the governor controls the supply of oil to the propeller, supplying or draining oil as appropriate to maintain constant engine speed. Propeller blade angle change is actuated by a hydraulic piston/cylinder combination mounted on the forward end of the propeller hub. The linear motion of the hydraulic piston is transmitted to each blade through a pitch change rod and a fork. A pitch change knob, located at the base of the blade, connects the blade to the fork. Each blade root is supported in the hub by a retention bearing. The retention bearing holds the blade firmly in the hub, but also allows the blade angle to change. Propeller forces, consisting of: 1) mechanical spring action, 2) counterweight centrifugal twisting moment, 3) centrifugal and aerodynamic twisting moment of the blades, and 4) an air charge on some propellers, in various combinations, are constantly present while the propeller is operating. The summation of these forces is opposed by a variable hydraulic force (oil pressure from the engine driven governor). Oil pressure is metered by the governor to oppose these constant forces and maintain a constant engine RPM.

Increasing or decreasing the oil volume within the hydraulic cylinder either increases blade angle to reduce engine RPM, or reduces blade angle to increase engine RPM. By changing the blade angle, the governor maintains constant engine RPM (within limits), independent of the throttle setting. If oil pressure is lost at any time, the summation of propeller forces, which is in direct opposition to the lost variable hydraulic force, either increases or reduces blade angle, depending upon propeller model. 2. Functional Description of Constant Speed Propeller Types A. Constant Speed Propellers ( )HM-( )( )Y( )( )-1( ) Refer to Figure 2-1. The -1 Series propeller models are constant speed, non-counterweighted propellers. The propellers are capable of blade angles between a low positive pitch (low pitch) and high positive pitch (high pitch). Centrifugal twisting moment acting on the blades moves the blades to a low blade angle (low pitch) to increase RPM. Since the centrifugal twisting moment is only present when the propeller is rotating, a mechanical spring is installed within the propeller to assist movement of the blades to a lower pitch position as RPM decays, and to reduce the propeller pitch to the low pitch stop when the propeller is static. With the blades at low pitch, the load on the starter when starting the engine is reduced significantly. Oil pressure opposes the spring and centrifugal twisting moment to move the blades to a high blade angle (high pitch), reducing engine RPM. If oil pressure is lost at any time, the propeller will move to low pitch. This occurs because the spring and blade centrifugal twisting moment are no longer opposed by hydraulic oil pressure. The propeller will then reduce blade pitch to the low pitch stop.

Constant Speed, Feathering Propellers ( )HM-( )( )Y( )( )-2( ) Refer to Figure 2-2. The -2 Series propellers are constant speed propellers that use an air charge, spring, and counterweights (if installed) to move the blades to high pitch/ feather position. Blade centrifugal twisting moment acts to move the blades to low pitch, but the air charge, spring, and counterweights overcome this force. Oil pressure against a propeller mounted hydraulic piston opposes the counterweight, spring, and air charge forces to move the blades to low blade angle (low pitch). The action of the air charge, spring, and counterweights tends to move the blades to a higher blade angle (high pitch), reducing engine RPM. Oil pressure toward low pitch increases engine RPM. If oil pressure is lost during operation, the propeller will feather. Feathering occurs because the air charge, spring, and blade counterweights are no longer opposed by hydraulic oil pressure. The air charge, spring and blade counterweights are then free to increase blade pitch to the feathering (high pitch) stop. Normal in-flight feathering of these propellers is accomplished when the pilot retards the propeller pitch control past the feather detent. This allows control oil to drain from the cylinder and return to the engine sump. The engine can then be shut down. Normal in-flight unfeathering is accomplished when the pilot positions the propeller pitch control into the normal flight (governing) range and an engine restart is attempted. When the engine is stopped on the ground, it is undesirable to feather the propeller, as the high blade angle prevents the engine from starting. To prevent feathering during normal engine shutdown on the ground, the propeller incorporates spring energized latches. If propeller rotation is approximately 800 RPM or above, the latches are disengaged by centrifugal force acting on the latches to compress the springs. When RPM drops below 800 RPM (and blade angle is typically within 7 degrees of the low pitch stop), the springs overcome the latch weight centrifugal force and move the latches to engage the high pitch stops, preventing blade angle movement to feather during normal engine shutdown.

Governors A. Theory of Operation A governor is an engine RPM sensing device and high pressure oil pump. In a constant speed propeller system, the governor responds to a change in engine RPM by directing oil under pressure to the propeller hydraulic cylinder or by releasing oil from the hydraulic cylinder. The change in oil volume in the hydraulic cylinder changes the blade angle and maintains the propeller system RPM. The governor is set for a specific RPM via the cockpit propeller control, which compresses or releases the governor speeder spring. Refer to Figure 2-3. When the engine is operating at the RPM set by the pilot using the cockpit control, the governor is operating onspeed. In an onspeed condition, the centrifugal force acting on the flyweights is balanced by the speeder spring, and the pilot valve is neither directing oil to nor from the propeller hydraulic cylinder. Refer to Figure 2-4. When the engine is operating below the RPM set by the pilot using the cockpit control, the governor is operating underspeed. In an underspeed condition, the flyweights tilt inward because there is not enough centrifugal force on the flyweights to overcome the force of the speeder spring. The pilot valve, forced down by the speeder spring, meters oil flow to decrease propeller pitch and raise engine RPM. Refer to Figure 2-5. When the engine is operating above the RPM set by the pilot using the cockpit control, the governor is operating overspeed. In an overspeed condition, the centrifugal force acting on the flyweights is greater than the speeder spring force. The flyweights tilt outward, and raise the pilot valve. The pilot valve then meters oil flow to increase propeller pitch and lower engine RPM. Propeller Owner's Manual 340 DESCRIPTION AND OPERATIONPage 2-14 Rev. 1 Aug/14 Refer to Figure 2-6. This figure illustrates a governor as a component of a synchronizing or synchrophasing system. A synchronizing system is employed in a multi-engine craft to keep the engines operating at the same RPM. A synchrophasing system not only keeps RPM of the engines consistent, but also keeps the propeller blades operating in phase with each other. Both synchronizing and synchrophasing systems serve to reduce noise and vibration. A Hartzell Propeller Inc. synchronizing or synchrophasing system uses one engine (the master engine) as an RPM and phase reference and adjusts the RPM of the remaining engine(s) [slave engine(s)] to match it. The RPM of the master engine is monitored electronically, and this information is used to adjust the voltage applied to the electrical coil on the slave governor(s). The voltage to the coil either raises or lowers a rod which changes the force of the speeder spring. In this manner, engine RPM and phase of the propellers is synchronized or synchrophased.
