OPERATING MANUAL PSP 601A-6 SECTION 17 POWER PLANT . GENERAL (Figure 1) The aircraft is powered by two General Electric CF34 turbofan engines. The engine is a dual-rotor, front-fan configuration with a bypass ratio of: 6.2:1 (aircraft 5001 to 5134) 6.26:1 (aircraft 5135 and subsequent). The low pressure (or NJ rotor consists of a single-stage fan driven by a four-stage low-pressure turbine. A high-pressure (or N2) rotor consists of a fourteen-stage axial-flow compressor driven by a two-stage turbine. For a two-engine operation under standard sea-level conditions, the engine is rated at a take-off thrust of 8,729 pounds. An automatic performance reserve (APR) system increases the standard take-off thrust rating to 9,220 pounds if an engine failure occurs. The engine airflow passes through the fan assembly and is divided into two airflow systems. The main airflow, bypass air, is routed around the core cowls and exhausts through the thrust reverser assembly, over the tailpipe fairing. The remaining airflow passes through the engine core consisting of the compressor, a combustion chamber, the high-pressure turbine and the low-pressure turbine. The hot gas is then exhausted through an exhaust nozzle. The compressor has a variable geometry system that varies the position of the compressor inlet guide vanes and the first five stages of the stator vanes. The system operates throughout the operating range of the engine to improve compressor efficiency and prevent stalling and surging. An accessory gearbox, driven by the N2 rotor, drives the engine lubrication pumps and fuel pump as well as an aircraft hydraulic pump and ac generator. The engine starter drives the N2 rotor through this accessory gear box. Bleed air is taken from the 10th and 14th stages of the compressor for air conditioning/pressurization, engine crossbleed starting, anti-icing and thrust reverser operation. . ENGINE FUEL SYSTEM (Figures 2 and 3) Each engine has a self-contained fuel system for the controlled distribution of fuel to the combustion chamber. Secondary functions of the system are control of the compressor variable geometry system, cooling of engine oil, and motive fuel supply to the aircraft fuel system ejector pumps (refer to Section 12). Sensors are installed at suitable locations in the system to provide the required inputs to the flight compartment controls and indicators. On aircraft 5001 to 5134, the principal components that make up the engine fuel system are described in a fuel flow sequence, starting at the firewall fuel shutoff valve through to the combustion chamber and the ecological drain system. On aircraft 5135 and subsequent, the principal components that make up the engine fuel system are described in a fuel flow sequence* starting at the firewall fuel shutoff valve through to the combustion chamber. SECTION 17 Page 1 Apr 10/95 esnEmSntyttr OPERATING MANUAL PSP 601A-6 A. Firewall Fuel Shutoff Valve This valve isolates the engine fuel system from the engine feed line (refer to Sections 9 and 12). B. Fuel Pressure Sensor This sensor, connected to a warning light in the flight compartment, allows monitoring of fuel pressure from associated ejector and electric fuel pumps in the aircraft fuel system, C. Engine Fuel Pump The engine-driven fuel pump contains a low-pressure section and a high-pressure section. The low-pressure section supplies fuel through the fuel heater to the fuel filter, and back to the high-pressure section of the pump. The high-pressure section is divided into two elements, designated the primary element and the secondary element. The primary element pumps fuel from the fuel filter to the fuel control unit and the secondary I element supplies high-pressure fuel to the aircraft tanks for motive I flow. I D. Fuel Heater (Aircraft 5001 to 5134) The fuel heater is an air-to-liquid heat exchanger which uses hot compressor bleed air to heat the fuel. The fuel temperature is maintained above 5*C, by a thermal sensor and an air modulating valve, to prevent icing in the fuel filter. A fuel bypass valve allows fuel to bypass the fuel heater should i t become clogged. | E. Heat Exchanger (Aircraft 5135 and subsequent) I Fuel is heated by the liquid to liquid (oil to fuel) heat exchanger. I F. Fuel Temperature Sensor This sensor, connected to an indicator in the flight compartment, allows monitoring of the fuel temperature and the fuel heater operation. | 6. Fuel Filter The fuel filter, located downstream of the fuel heater, contains a disposable filter element. A bypass valve allows the fuel to bypass the filter element should it become clogged. A differential pressure switch connected to a warning light in the flight compartment warns of an impending bypass condition. Should a bypass occur, a red button on the housing rises to indicate the condition. SECTION 17 Page 2 Apr 10/95 OPERATING MANUAL PSP 601A-6 J H. Fuel Control Unit (FCU) The FCU i s a hydro-mechanical/electrical device consisting of two sections: a fuel metering section and a computer section. The flight compartment throttle lever movement is transmitted to the FCU which in turn controls engine speed in one of the following two modes: - At relatively low power settings, the FCU hydro-mechanically meters the fuel to the injectors to control engine N2 speed. In this mode, matched movement of the throttle levers produces matched N2 speeds, but Ni speeds and thrust may be mismatched between the engines. - At take-off, climb and cruise power settings, the engine is Ni speed controlled. In this mode, the FCU electrically responds to Ni speed references. (Electrical power for operation in this mode is supplied by an Ni driven alternator, completely independent of the aircraft electrical system). Matched movement of the throttle levers produces matched Ni speeds, hence matched thrust between the engines. This engine speed control can be selected on or off by a switch in the flight compartment. If selected off, the engine speed control reverts to the N2 mode described above for all engine speeds. The FCU also meters pressurized fuel from the engine-driven fuel pump to the two actuators for the compressor variable geometry system. The actuators move the compressor inlet guide vanes, and the affected stator vanes open as engine speed increases and close as speed decreases. j I. Fuel Flow Transmitter This transmitter sends fuel flow information to be displayed on the associated fuel flow indicator in the flight compartment. I J. Oil Cooler The oil cooler heats the fuel before the fuel enters the combustion chamber while cooling the engine oil. (Refer to paragraph 4.F.) I K. Fuel-Flow Distributor and Injectors (Aircraft 5001 to 5134) The fuel-flow distributor precisely meters the fuel to the injectors. The injectors inject fuel into the combustion chamber. At shutdown, the distributor drains fuel to an ecological drain system. J L. Fuel Manifold (Aircraft 5135 and subsequent) Metered fuel leaves the FCU, thru fuel flow transmitter and enters fuel I manifold. The manifold consists of 2 separate halves, which form one J continuous ring which encircles the combustion chamber frames. M. Fuel Injectors (Aircraft 5135 and subsequent) Integral with the continuous ring are 18 fuel injector hoses which connect to 18 fuel injectors. Each injector has 2 independent fuel flow passages, a primary and a secondary. The primary introduces fuel into I the combuster at lower power settings (start-up-idle) the secondary introduces fuel at higher power settings, resulting in 2 cones of fuel. I N. Ecological Drain System (Aircraft 5001 to 5134) This system prevents the fuel collected by the shut-down fuel drain system from being discharged to the atmosphere. The ecological drain tank collects this fuel which is then routed to an aspirator in the engine fuel feed line to be consumed during the subsequent engine operation. SECTION 17 Page 3 Apr 10/95 OPERATING MANUAL PSP 601A-6 3. AUTOMATIC PERFORMANCE RESERVE (APR) SYSTEM (Figures 2 and 4) The APR system monitors engine thrust levels at high power settings and automatically commands an increase in thrust on both engines if a predetermined thrust loss is detected on one of them. To arm the system, both engine speed control switches must be selected to ON and the APR switch selected to ARM. With the system armed and the engines operating in the Ni speed control mode, an Ni drop to 5000 rpm (approximately 67.5% Ni) on either engine causes the APR controller to command an N2 speed increase of 167 rpm (approximately 2% Ni) on both engines. The engine still operating at the normal take-off Nx has its Ni increased by approximately 2% while the engine affected by the Ni drop reverts to N2 speed control mode, hence not responding to the Ni speed increase command. NOTE: The APR system does not affect or override the throttle lever inputs to the FCU. Therefore, it is possible to advance the throttles and obtain power settings higher than the normal (non-APR) take-off thrust. Should this condition be followed by a power loss on one of the engines, the other engine would respond to the APR command and further increase Ni above its previously set higher power setting, with the likely result of its inter-turbine temperature (ITT) limits being exceeded. Two system tests, a static and a dynamic system test, ensure system serviceability before take-off- The static test is performed with the engines running at idle, using a selector switch in the flight compartment. The dynamic test is conducted automatically by the APR controller, with the system armed and when the engines are accelerated through 83.5% Ni for take-off. The dynamic system test cannot be repeated unless the weight-on-wheels status changes or the system is selected off and re-armed. 4. ENGINE OIL SYSTEM (Figures 5 and 6) Each engine is lubricated and cooled by its own self-contained oil system. In addition to an engine-mounted oil storage tank, an oil replenishment system located in the rear equipment bay is also provided. Sensors are installed at suitable locations in the system to provide inputs to the oil temperature and pressure indicators in the flight compartment. Impending oil filter blockage is also monitored. The principal components that make up the engine oil system are described in a flow sequence, starting at the oil replenishment system through to the oil return to the oil storage tank. A. Oil Replenishment System This system is used to add oil to the oil storage tanks on both engines. It consists of a replenishment tank, an electric pump, an OIL LEVEL CONTROL panel and a selector valve. SECTION 17 Page 4 Apr 10/95 OPERATING MANUAL PS? 601A-6 The OIL LEVEL CONTROL panel indicates if the storage tanks are full and also tests the replenishment system. The selector valve is manually selected to the desired left or right storage tank. The electric pump transfers oil from the replenishment tank to the selected storage tank. The replenishment tank is gravity-filled. Its tank-mounted sight gauge indicates oil level. B. Oil Storage Tank Each storage tank oil level can be determined by a dips tic mounted in the filler cap. The tank can be directly gravity filled or remotely filled using the replenishment system. C. Oil Temperature Sensor This sensor, located in the storage tank and connected to an indicator in the f l i g h t compartment, allows monitoring of engine oil temperature including the oil cooler operation. D. Oil Circulation Oil flows from the storage tank to the lube pump. The pressurized oil is then directed through the f i l t e r , the cooler and then to the various engine components requiring lubrication and cooling. Oil is returned to the storage tank by scavenge pumps. E. Oil Filter The o i l f i l t e r consists of a f i l t e r element, a differential pressure switch connected to an oil pressure impending bypass indicator, and a bypass valve. The impending bypass indicator, located in the rear equipment bay, warns of an impending blockage of the f i l t e r element. Should the f i l t er become clogged, the bypass valve would open to allow unfiltered oil to maintain engine lubrication. F. Oil Cooler The o i l cooler is an oil-to-fuel heat exchanger which uses fuel as a cooling medium for the engine o i l . G* Oil Pressure Sensor and Low Oil Pressure Switch The pressure sensor and the low pressure switch, connected to their indicator and warning light respectively in the flight compartment, provide independent indications of engine oil pressure. Both circuits sense the differential oil pressure between the lube pump discharge and the scavenge pump suction. SECTION 17 Page 5 Apr 02/87 OPERATING MANUAL PS? 601A-6 ENGINE CONTROLS (Figure 7) Each throttle lever with its hinged thrust reverse (TR) lever is connected to i t s engine fuel control unit (FCU) through a single flexible cable extending from the throttle quadrant in the flight compartment to the throttle control gearbox on the engine. This system transfers all throttle and thrust reverse lever movement to the engine to command forward or reverse thrust as well as fuel shutoff. This system also mechanically provides a t a c t i l e feedback to the throttle and thrust reverse levers when the FCU is kept at, or should be returned to, idle by the t h r o t t l e retarder system. Individual throttle lever release latches prevent inadvertent selection of fuel SHUT OFF or fuel-on (IDLE) and individual thrust reverse lever release latches prevent inadvertent operation of thrust reverse levers. Mechanical interlocks within the throttle quadrant also prevent a thrust reverse lever from being operated unless its throttle lever is at IDLE, or prevent a throttle lever from being advanced above IDLE when i ts thrust reverse lever is pulled up from the forward idle position. A t h r o t t l e lever friction adjustment control is also provided. THRUST REVERSER (Figures 7 and 8) Each engine is equipped with a thrust reverser to assist in aircraft braking after landing. When the thrust reverser is deployed, a translating cowl moves rearward on tracks driven by a pneumatic actuator and uncovers forward facing cascade vanes. Blocker doors, operated by interconnected linkages, move inward to block the fan air exhaust duct and redirect the fan exhaust air through the cascade vanes. The system is powered by 14th stage bleed air. A. Operation Each thrust reverser is armed for operation by i ts associated REVERSE THRUST switch/light. With the throttle lever at IDLE and either a weight-on-wheels signal or a 16-knot wheel spin-up signal, raising the thrust reverse lever to the deploy position initiates the following deployment sequence: - Wing and engine anti-icing shutoff valves, i f open, are closed to conserve 14th stage bleed air for the reverser operation. - 14th stage bleed air unlocks the reverser from i t s stowed position and powers a pneumatic drive unit (PDU) which deploys the reverser. • As the reverser is fully deployed, i t is locked in position by the PDU, and the thrust reverse lever is mechanically released by a throttle retarder system and is electrically released by a throttle solenoid, so that thrust settings up to maximum reverse thrust can be selected. SECTION 17 Page 6 Apr 02/87 canadair ctianenQer OPERATING MANUAL PSP 601A-6 Moving the thrust reverse lever back to the deploy position t h r o t t l e s the engine down to reverse i d l e - Continued movement of the lever to the f u l ly down position stows and locks the reverser, in the reverse sequence to the deployment described above. As the reverser is f u l l y stowed and locked in position by the PDU, the t h r o t t l e retarder system mechanically releases the t h r o t t l e lever so that forward thrust setting above IDLE can be selected again. Wing and engine a n t i - i c i ng is also restored to normal controls. After the above sequence to stow and lock the reverser is complete, the reverser can be disarmed by i t s associated REVERSE THRUST switch/light. B. Safety Features Each reverser is protected by the safety features described below. (1) Throttle Retarder System The t h r o t t le retarder system is a mechanical system connected to the thrust reverser and the engine FCU control linkage. If the engine is t h r o t t l ed above i d l e and there is an inadvertent thrust reverser deployment, the t h r o t t l e retarder system returns the FCU to i d l e , and, through the i n t e r l i n k cable, pulls the t h r o t t l e lever to IDLE. This system also operates during normal operation of the reverser, as described in paragraph 6.A. above. (2) Throttle Lockout System The throttle lockout system prevents movement above IDLE of a previously retarded throttle lever if the aircraft is airborne and the thrust reverser moves from the fully stowed position. Under such conditions, initial movement of the thrust reverser energizes a throttle lockout solenoid which locks the throttle linkage at the FCU and prevents throttle lever movement beyond IDLE. If the reverser is returned to the stowed position, the throttle lockout solenoid is de-energized and freedom of movement is returned to the throttle lever. (3) Auto Stow System In the case of an uncommanded movement of the reverser from the stowed position, a microswitch commands the PDU to return the reverser to the stowed position. SECTION 17 Page 7 Apr 02/87 OPERATING MANUAL PSP 601A-6 (4) Emergency Stow System If the REVERSER UNLOCKED light is on and the auto stow system fails to stow the reverser, the appropriate THRUST REVERSER EMERG STOW switch/light can be pressed to ensure positive operation of the sys^-- to the stowed position. (5) Safety Relay Actuation of the thrust reverse lever with the aircraft not on the ground causes the REVERSE THRUST UNSAFE TO ARM light to come on. ENGINE INSTRUMENTS (Figure 9) Engine instruments monitor Nl %rpm, inter-turbine temperature (ITT), N2 %rpm, fuel flow, oil temperature and oil pressure. A. Signal Data Converter (SDC) The SDC controls the power supply and provides automatic dimming to the engine indicator systems.. Two power supplies are divided within the SDC into dual lamp-processing and signal-processing power supplies. B. Engine Instruments Each instrument provides a vertical analog display of the relevant engine variable using a series of miniature incandescent lamps inside the indicator, which provide the light source for the vertical row of coloured light segments. Digital displays on the Nl, ITT, N2 and FUEL FLOW indicators provide more accurate indications when compared with the readings on the vertical scales. ENGINE BLEED AIR Engine bleed air consists of two systems, each with its own source. One source is at the 10th stage and the other is at the 14th stage of the compressor of each engine. Each system contains distribution ducting, shutoff valves, isolator valves and check valves. Both systems are protected by a bleed air leak detection system. The flight compartment BLEED AIR and ANTI-ICE control panels provide the necessary controls and indicators. SECTION 17 Page 8 Apr 02/87 cacntiaaauaeirn cjer OPERATING KANUAL PSP 601A-6 Tenth Stage Bleed Air (Figures 10 and 11) The 10th stage bleed a i r system can be supplied from the l e f t and right engines or from the APU, or from a ground a i r supply unit through an external connection on the lower left side of the rear fuselage. The 10th stage system supplies bleed air to the following systems: Air conditioning/pressurization Cabin pressurization control Footwarmer/demister and emergency pressurization Engine s t a r t i ng A bleed air isolator valve is normally closed to separate the l e f t and right d i s t r i b u t i o n ducting. This isolator valve is automatically opened by the engine s t a r t system to ensure air supply to both engines regardless of the a i r source. It can also be selected open when required, i . e . , to supply both ACUs from a single engine bleed source. A l e f t and r i g h t pressure indicator receives signals from two sensors, ont on each side of the isolator valve, for continuous monitoring. For operation of LH and RH footwarmer/demister valves and l e f t and r i g h t ACU valves, refer to Section 2. Fourteenth Stage Bleed Air (Figures 11 and 12) The 14th stage bleed a i r system is supplied only by the l e f t and right engines. The 14th stage system supplies bleed air to the following systems: Wing a n t i - i c i ng Engine a n t i - i c i ng Thrust reverser The operation of engine and wing a n t i - i c i ng valves (including the isolator valve) is controlled by the ANTI-ICE control panel (refer to Section 14). Bleed Air Leak Detection and Warning System (Figure 13) Six temperature sensors ( f i r e - w i r e type) are attached to the bleed a ir ducts and are connected to two bleed air leak detection control units. Dual detection loops are provided for the l e f t and r i g h t sections of the 10th stage bleed air system, and single loops are provided for the 14th stage bleed a i r system, the fuselage pylons and the a n t i - i c i n g ducts running through the fuselage and wings. If a leak occurs, the hot bleed a i r escaping i s detected by the temperature sensors and i n i t i a t e s a warning signal. SECTION 17 Page 9 Apr 02/87 cana&air cftanenoer OPERATING MANUAL PSP 601A-6 The warning signal is picked up by its leak detection control unit and transmitted to the flight compartment via a centrally located flashing DUCT FAIL warning light as well as an appropriate individual DUCT FAIL warning light on the control panel for the system affected by the leak. The individual DUCT FAIL warning light identifies the defective duct whicn can then be depressurized and isolated using the BLEED AIR control panel. A bleed air leak annunciator panel, behind the copilot's seat, also provides for fault isolation through eight latching magnetic indicators. With the exception of the indicators on the bleed air leak annunciator panel, all of the warning indicators go out when their associated temperature sensors have cooled sufficiently. Warnings and testing of the bleed air leak detection system are summarized in Figure 13. 9. ENGINE STARTING AND IGNITION SYSTEMS (Figure 14) The engine starting and ignition systems consist of a pneumatically driven air turbine starter, ignition-exciter boxes and igniter plugs for each engine. The systems are controlled by individual switch/lights in the flight compartment. The starter transmits starting torque to the N2 rotor through the accessory gearbox. An automatic centrifugal shutoff switch opens at a preset rpm to protect the starter against overspeed. The 10th stage bleed air system supplies the starter through a starter valve. Each engine has two ignition systems, A and B, each system connected to its igniter plug in the combustion chamber. The systems are powered by 115-volt ac power. A. Ground Starting The APU, an external ground air source or an operating engine can be used to supply the 10th stage bleed air system for engine starting. An IGN A and/or IGN B switch/light arm(s) the associated igniter plugs on both engines. With the 10th stage bleed air system pressurized, pressing a START switch/light initiates the starting sequence on the associated engine. Refer to Figure 14 for description of the starting sequence. B. In-Flight Starts An IN FLIGHT START switch/light provides a separate power supply and fires both igniter plugs (A and B) on the selected engine without any other switch/light having to be operated- However, if the windmilling rpm is less than 131 N2, starter assist using the START switch/light is required. SECTION 17 Page 10 Apr 02/87 OPERATING MANUAL PSP 601A-6 C. Continuous Ignition A CONT IGN switch/light provides continuous i g n i t i on to both engines through the pre-selected A and/or B i g n i t e r plugs. Firing of the igniter plugs is continuous until the CONT IGN switch/light is pressed out. 10. ENGINE VIBRATION MONITORING SYSTEM (Figure 15) The engine vibration monitoring (EVM) system provides a continuous indication of the vibration level of each engine. The main components of the system include a transducer mounted on the compressor casing of each engine, a signal conditioner and an indicator panel in the f l i g h t compartment. Each transducer generates an electrical signal proportional to the intensity of engine vibration. The signal conditioner converts these signals into values readable on the EVM indicator. An alarm c i r c u i t causes an amber caution light on the EVM indicator panel to come on i f the vibration level of either engine exceeds 1.7 MILS for a period greater than 3 seconds. This 3-second delay prevents spurious warnings caused by high transient engine vibrations.

REVERSE THRUST REVERSER UNLOCKED REVERSE THRUST THRUST REVSISE (TR) LEVERS With throttle levels at IDLE, putting onTR levels deploy levsisers if following conditions met: - REVERSE THRUST switch/lights have armed reversers. • Aircraft on ground or wheel spinup exceeds 16 knots. Throttle solenoids prevent TR lever movernem beyond deploy (or reverse idle) position until reverser assemblies fully deployed. Once reversers fully deployed, TR levers regulate reverse thrust from reverse idle to maximum reverse power. Reverser operation shuts off 14th stage bleed air to engine and wing GO-AROUND SWITCHES Momentarily push button switches. These switches are associated with go-around mode of flight director system. Returning TR levers to forward IDLE (fully down) stow reversers. Once reversers stowed, throttle levers can be moved forward to increase thrust. NOTE Reverser deployment do not prevent throttle levers from being selected to SHUTOFF. THROTTLE SETTINGS SHUTOFF - Shuts off fuel to engine at the FCU. Located at rear throttle IDLE - Lowest forward thrust setting. Located at idle throttle lever stop. MAX POWER - Highest forward thrust setting. Located at forward throttle lever stop. PUSH LEFT PUSH RIGHT GLARESHIELD THROTTLE LEVERS Control forward thrust and acts a fuel shutoffs. Remain locked at IDLE position during thrust reverser operation. THROTTLE LEVER RELEASE LATCHES Lift to advance throttle levers from SHUTOFF to IDLE positions or retard throttle levers from IDLE to SHUTOFF positions. THRUST REVERSE LEVER RELEASE LATCHES Lift to release TR levers from forward IDLE stops. ^ 3 THROTTLE LEVER FRICTION ADJUSTMENT Adjusts friction on throttle levers only. Rotate control clockwise to increase friction. CENTRE PEDESTAL REVERSE THRUST SWITCH/UGHTS When pressed in, arms thrust reverser system and puts on amber ARMED light.
