Propeller Owner's Manual 340

WARNINGPeople who operate Wing-In-Ground-effect (WIG) craft should recognize that various types of risks are involved; and they should take all precautions to minimize them, since they cannot be eliminated entirely. The propeller is a vital component of the craft. A mechanical failure of the propeller could create vibrations sufficiently severe to damage the craft, possibly causing it to become uncontrollable.

Propellers are subject to constant vibration stresses from the engine and airstream, which are added to high bending and centrifugal stresses.

Before a propeller is determined to be safe to operate on a craft, an adequate margin of safety must be demonstrated. Even though every precaution is taken in the design and manufacture of a propeller, history has revealed rare instances of failures, particularly of the fatigue type.

It is essential that the propeller is properly maintained according to the recommended service procedures and a close watch is exercised to detect impending problems before they become serious. Any grease or oil leakage, loss of air pressure, unusual vibration, or unusual operation should be investigated and repaired, as it could be a warning that something serious is wrong.

Aug/13MESSAGE


For operators of uncertified or experimental craft an even greater level of vigilance is required in the maintenance and inspection of the propeller. Experimental installations often use propeller-engine combinations that have not been tested and approved. In these cases, the stress on the propeller and, therefore, its safety margin is unknown. Failure could be as severe as loss of propeller or propeller blades and cause loss of propeller control and/or loss of craft control.

Experimental craft may operate with unapproved engines or propellers or engine modifications to increase horsepower, such as unapproved crankshaft damper configurations or high compression pistons. These issues affect the vibration output of the engine and the stress levels on the propeller. Significant propeller life reduction and failure are real possibilities.

Visually inspect metal and composite blades for cracks. Inspect hubs, with particular emphasis on each blade arm for cracks. Eddy current equipment is recommended for hub inspection, since cracks are usually not apparent.

1. Replacement Time (Life Limits)A. The applicable certification agency may establish specific

life limits for certain component parts, as well as the entire propeller. Such limits require replacement of the identified parts after a specified number of hours of use.

B. The following data summarizes all current information concerning Hartzell Propeller Inc. life limited parts as related to propeller models affected by this manual. These parts are not life limited on other installations; however, time accumulated toward life limit accrues when first operated on craft/engine/propeller combinations listed, and continues regardless of subsequent installations (which may or may not be life limited).(1) Propeller models affected by this manual currently do not

have any life limited parts.

1. Description of Propeller and SystemsA. 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 thebladefirmlyinthehub,butalsoallowsthebladeangletochange.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.



Oil under pressure from the engine-driven governor is supplied to the hydraulic cylinder through the pitch change rod. 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 TypesA. 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 whenstartingtheengineisreducedsignificantly.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.

B. Constant Speed, Feathering Propellers ( )HM-( )( )Y( )( )-2Refer 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.Normalin-flightfeatheringofthesepropellersisaccomplished 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. Normalin-flightunfeatheringisaccomplishedwhenthepilotpositionsthepropellerpitchcontrolintothenormalflight(governing) range and an engine restart is attempted. Some craft are equipped with a hydraulic accumulator, which stores a supply of oil under pressure. This oil supply is releasedtounfeatherthepropellerduringanin-flightenginerestart.Pressurizedoilisdirectedtothepropeller,resultingin blade angle decrease. The propeller begins to windmill, and engine restart is possible.



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 incorporatesspringenergizedlatches.Ifpropellerrotationis 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.

4. GovernorsA. 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 setforaspecificRPMviathecockpitpropellercontrol,whichcompresses 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 centrifugalforceactingontheflyweightsisbalancedbythespeeder 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 flyweightstiltinwardbecausethereisnotenoughcentrifugalforceontheflyweightstoovercometheforceofthespeederspring. The pilot valve, forced down by the speeder spring, metersoilflowtodecreasepropellerpitchandraiseengineRPM.Refer to Figure 2-5.

AHartzellPropellerInc.synchronizingorsynchrophasingsystem 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 ofthepropellersissynchronizedorsynchrophased.

B. Propeller De-ice SystemA propeller de-ice system permits ice to form, and then removes it by electrically heating the de-ice boots. The ice partially melts and is thrown from the blade by centrifugal force.(1) System Overview

(a) A de-ice system consists of one or more on/off switches, a timer or cycling unit, a slip ring, brush blocks, and de-ice boots. The pilot controls the operation of the de-ice system by turning on one or more switches. All de-ice systems have a master switch, and may have another toggle switch for each propeller. Some systems also have a selector switch to adjust for light or heavy icing conditions.

(b) The timer or cycling unit determines the sequence of which blades (or portion thereof) are currently being de-iced, and for what length of time. The cycling unit applies power to each de-ice boot or boot segment in a sequential order.

(c) A brush block, which is normally mounted on the engine just behind the propeller, is used to transfer electricity to the slip ring. The slip ring rotates with the propeller, and provides a current path to the blade de-ice boots.

(d) De-ice boots contain internal heating elements. These boots are securely attached to the inboard leading edges of each blade with adhesive.

E. Air Charge Pressure Check (-2 Propellers)(1) Perform an air charge pressure check before propeller

installation. Refer to the Air Charge section of the Maintenance Practices chapter of this manual.(a) If the air pressure loss is less than 10 percent of the

specified pressure, reservice the propeller. (b) If the air pressure loss is greater than 10 percent

of the specified pressure, repair the propeller. This repair must be performed at an appropriately certified propeller repair station.

3. Spinner Pre-InstallationA. General

(1) The spinner support must be mounted before the propeller can be installed. The spinner will mount to a bulkhead installed on the propeller hub. Follow the applicable directions in this section.

(2) Refer to Figure 3-3. Remove the nuts from the hub clamping bolts that are located on either side of the blade shank. Do not remove the bolts. The remaining nuts/bolts should not be disturbed.

(3) Refer to Figure 3-3. The spinner may be supplied with long hub clamping bolts. If the bolts were supplied with the spinner, remove the bolts on either side of the blade shank and replace them with the bolts supplied with the spinner. The supplied hub clamping bolts will be longer than those removed from the hub.NOTE: Depending upon the installation, the propeller

hub may have been shipped from the factory with the longer hub clamping bolts installed. In this case, the hub clamping bolts will not be supplied with the spinner.

B. Installation of a Metal Spinner Bulkhead on a Propeller Hub (1) Refer to Figure 3-4. Put the spinner bulkhead spacers on

the hub clamping bolts. Install the spinner bulkhead over the installed spacers on the hub clamping bolts.

CAUTION: A MINIMUM OF ONE THREAD OF THE HUB CLAMPING BOLT MUST BE VISIBLE AFTER THE SPINNER MOUNTING NUT IS INSTALLED.

(2) When the spinner bulkhead is installed, there must be no less than one thread of the hub clamping bolt exposed beyond the spinner mounting nut. A total of three washers in two areas may be installed beneath the spinner mounting nut to achieve this result. On some installations, it may be necessary to install spacers and one or more washers beneath the head of the bolt to avoid interference with craft cowling.(a) Additional washers (as many as four) may have

been used for hub clamping purposes during assembly of the propeller. 1 Use the quantity of washers required when

installing the bulkhead for correct spinner position. Refer to Figure 3-4.

2 After the correct installation of the spinner, any remaining washers may be discarded.

(3) Install at least one flat washer F and a new self-locking spinner mounting nut G on each hub clamping bolt used to mount the spinner bulkhead. Refer to Table 3-2.

(4) Torque each spinner mounting nut in accordance with Table 3-1, Figure 3-1, and Figure 3-2.
