Figure 2 The propeller assembly is a four bladed, constant speed, variable pitch propeller. The propeller is a reversing and feathering type, the pitch changing mechanism being hydraulically operated towards fine and reverse pitch and mechanically assisted to coarse and feathering pitch, by coil springs and blade counterweights. The propeller assembl comprises the following sub assemblies. Spinner - Hub assembly - Blades and bearings = Cylinder - Slip ring assembly A. Spinner A cone shaped, light alloy spinner shell, encloses the blade roots and streamlines the propeller. The spinner has four blade apertures at the rear open end to locate over the blade roots. A shell support, riveted to the inside of the spinner shell, houses a rubber ring which locates on the propeller cylinder when the spinner is installed. The spinner is secured to the spinner backplate by twelve screus. B. Hub assembly This is a split assembly, consisting of tuo halves secured together by eight bolts. Eight threaded holes are provided in the hub rear wall to receive the mounting bolts, together with two plain holes for locating on the engine shaft flange dowels. Eight equally spaced threaded holes in the hub front face receive the cylinder attachment bolts. A sealing ring on the spigot diameter prevents Leakage at the hub/cylinder joint, and the bore of each half, houses a sealing ring. The hub assembly provides four blade ports to receive the blades. A seal in each blade port, prevents leakage of blade Learing grease between the blade root and hub arm. 61-10-00 Page 1 Feb 15/01 iM ‘Senies 3200 MAINTENANCE MANUAL. 61-10-00 Page 2 Oct 30/98 Sexies 3200 MAINTENANCE MANUAL Blades and bearings Each blade rotates about its axis on a bearing assembly during pitch change. Each is individually balanced by the insertion of lead wool in a central bore in the root and retained by a plug. Propeller de-icing boots are fitted to each blade and are connected by the de-icer harness to the slip ring assembly. A counterweight is fitted to each blade to assist in pitch changing to coarse and feather. The single-row blade bearing assembly ic of the split race type, incorporating a set of 21 matched balls. The large top thrust race locates in the hub, with the small bottom thrust race locating on the blade root. It is retained by a bearing sleeve, which is secured by a spring ring. An operating pin with a needle bearing assembly, is secured to the bottom face of the blade by a socket screw and is driven by the crosshead located in the hub cylinder The cylinder houses the coil springs and piston. Diametrically opposed on the cylinder are two spring loaded start Locks, which hold the piston and consequently the propeller blades, at or near 0° for engine starting. A plug titted in the bore at the front of the cylinder, provides access to the oil transfer (beta) tube. The beta tube screws into the crosshead and terminates in the beta sleeve on the engine. This tube carries the pressure/exhaust oil during all pitch change operations. Propeller static balance weights are fitted, as required, under the cylinder attachment bolt heads, to balance the propeller to within 0.29 ka cm (4 in oz.). Slip ring assembly The slip ring assembly is secured on the rear of the hub and transmits the electrical current from the brush gear to the Ce-icing boots of the blades. Operation (Ref. Figure 1) (Ref. Figure 3 The start locke hold the blades at the propeller ng for minimum starting torque. With the start locks released, the blades are hold in fine pitch by ofl pressure. 61-10-00 Page 3 Feb 15/01 iM ‘Senies 3200 MAINTENANCE MANUAL. 61-10-00 Page & Oct 50/98 Sexies 3200 MAINTENANCE MANUAL If the propeller is not held on the start locks, the Locks can be engaged using an electrically driven unfeathering pump (Ref. Chapter 61-20-00). To increase blade pitch the pressure oil is vented to the drain side of the system. The springs and blade counterweights then assist the blades towards coarse pitch With the oil pressure further reduced, the blades continue towards coarse pitch until the feather stop is reached. Reverse pitch is obtained by increasing the oil pressure to force the piston against, and overcome the reverse spring. A stop is supplied for the full reverse blade angle. On engine shut down, selection of reverse pitch, at propeller speeds less than 300 RPM, makes sure that the start locks are engaged ready for Subsequent restarting. 61-10-00 Page 5 Feb 15/01 iM ‘Senies 3200 MAINTENANCE MANUAL. 61-10-00 Page 6 Oct 30/98 Sexies 3200 MAINTENANCE MANUAL #* For Aircraft ALL+* SPINNER REMOVAL/INSTALLATION 1, Remove Spinner (Ref.

A synchrophaser system is provided for each engine. It automatically matches the two engine rotational speeds, and positions Lheir associaled propellers al the correct phase relationship. 2. Unfeathering pump This electrically driven pump pressurizes and directs engine oil to unfeather the propeller. 61-20-00 Page 1 Page left intentionally blank Sexies 3200 MAINTENANCE MANUAL #* For Aircraft ALL+* SYNCHROPHASER DESCRIPTION AND OPERATION 1, General The synchrophaser system comprises a monopole speed pickup and propeller governor on each engine and a synchrophaser control unit in the left bulkhead panel (fuselage STN 130), automatically matches the rotational speeds of the two engines and positions the propellers at a pre-set phase relationship. 2. Description and Operation (Ref. Figure 1) Left and right monopole speed pickups, 1KB4 and 2KB4, are mounted in brackets attached to the propeller de-ice brush assemblies. They generate electrical pulses induced from a target located on the de-icing slip ring at the rear of the propeller. The targets on both the left and right engines are aligned with a propeller blade. Phase differences are fed into the synchrophaser control unit, 1KB3. Any differences in the phase relationship will cause the control unit to output a signal to electro-magnetic coils, mounted in the propeller governor of the affected engine. The varying voltage on the coil of the affected engine influences the operation of flyweights. These control the flow of oil to the propeller, to change the pitch and thus control the engine speed The system ic controlled by a PROP SYNCHRO ON/OFF cwitch (1KB2) and supplied from the 28V dc main bus-bar via circuit breaker PROP SYNC PR DUMP 1KB1. The PROP SYNCHRO ON/OFF switch is located in the roof panel. 61-20-02 Page 1 iM ‘Senies 3200 MAINTENANCE MANUAL.

Chapter 71-00-00, page block 501 ). Manually synchronize propellers by reducing rpm of faster propeller to minimize effect of lost motion in governor control linkage. If necessary, reduce power to a point where torque limiting is not operating. Set PROP SYNCHRO switch to ON and allow system to stabilize for a few seconds. Very slowly, reduce left propeller rpm unti synchronization is just lost. Note rpm difference Very slowly, reduce right propeller rpm until synchronization is regained and again lost. Note rpm difference (+1% MAXIMUM), Set PROP SYNCHRO switch to OFF. Set Left and right propeller rpm to within differential noted at (Ref. Step 5.A.(5)) or (Ref. Step 5.A.(6)) . Set PROP SYNCHRO switch to ON, make sure synchronization is established and need within a few seconds. Make sure slower propelter achieve synchronization. 61-20-02 Page 204 Apr 15/08 JETSTREAM Sexies 3200 MAINTENANCE MANUAL Monopole Speed Pickup - Installation Figure 202 61-20-02 Page 205 te cea ae JETSTREAM ‘Senies 3200 MAINTENANCE MANUAL (10)Set PROP SYNCHRO switch to OFF.
