POWERPLANT PRESENTATION
The engine is attached to the wing pylon by mounts,
located forward and aft of the core section.
Cowls enclose the periphery of the engine so as to form
the nacelle, which is the aerodynamic structure around
the engine.
The cowling assembly consists of:
- The inlet cowl.
- The fan cowls.
- The thrust reverser cowls.
- The primary exhaust (primary nozzle and
centerbody).

ENGINE PRESERVATION
The procedures which follow are recommended as the
minimum necessary to protect the CFM56 engine against
corrosion, liquid and debris entering the engine, and
atmospheric conditions during periods of storage, and
inactivity; or following an In Flight Shut Down (IFSD).
These procedures are also recommended for installed
engines on inoperative aircraft or an engine not to be
operated for more than thirty days.

TRAINING MANUAL
(-5B):
At static take-off power, the CFM56-5B engine by-pass
ratio is between 5.4:1 and 6:1, depending on the engine
model, which means that the secondary airflow takes
in between 5.4 and 6 times more air than the primary
airflow.

Control Alternator.
The control alternator provides two separate power
sources from two independent windings.
One is hardwired to channel A, the other to channel B.
The alternator is capable of supplying the necessary
power above an engine speed of approximately 10% N2.
GSE test equipment provides 28 VDC power to the ECU
during bench testing and it is connected to connector J15.

ENGINE SENSORS
Aerodynamic stations.
The ECU requires information on the engine gas path
and operational parameters in order to control the engine
during all flight phases.
Sensors are installed at aerodynamic stations and
various engine locations, to measure engine parameters
and provide them to the ECU subsystems.
Sensors located at aerodynamic stations have the same
number as the station, e.g. T25.
Sensors placed at other engine locations have a
particular name, e.g. T case sensor.

Starting SYSTEM
The FADEC is able to control engine starting, cranking
and ignition, using aircraft control data.
Starting can be performed either in Manual Mode, or
Automatic Mode.
For this purpose, the ECU is able to command:
- Opening and closing of the Starter Air Valve (SAV),
- Positioning of the Fuel Metering Valve (FMV),
- Energizing of the igniters.
It also detects abnormal operation and delivers specific
messages.

STARTING SYSTEM
When the starter air valve is energized, it opens and air
pressure is delivered to the pneumatic starter.
The pneumatic starter provides the necessary torque to
drive the HP rotor, through the AGB, TGB and IGB.
The necessary air pressure for the starter comes from:
- The APU.
- The other engine, through the cross bleed system.
- A ground power unit (25 to 55 psi).

The purpose of the ignition system is to ignite the air/fuel
mixture within the combustion chamber.
The engine is equipped with a dual ignition system,
located on the right-hand side of the fan case and both
sides of the core.
The ignition system has two independent circuits
consisting of :
- 2 high energy ignition exciters.
- 2 ignition lead assemblies.
- 2 spark igniters.
A current is supplied to the ignition exciters and
transformed into high voltage pulses. These pulses are
sent, through ignition leads, to the tip of the igniter plugs,
producing sparks.

Power Management
The power management function computes the fan speed
(N1) necessary to achieve a desired thrust.
The FADEC manages power, according to two thrust
modes:
- Manual mode, depending on the Thrust Lever Angle.
- Autothrust mode, according to the autothrust
function generated by the autoflight system.
Power management uses N1 as the thrust setting
parameter.
It is calculated for the appropriate engine ratings (coded
in the identification plug) and based upon ambient
conditions, Mach number (ADIRUs) and engine bleeds
(ECS).

FUEL DISTRIBUTION
Fuel from the A/C tank enters the engine fuel pump,
through a fuel supply line.
After passing through the pump, the pressurized fuel
goes to the main oil/fuel heat exchanger in order to cool
down the engine scavenge oil.
It then goes back to the fuel pump, where it is filtered,
pressurized and split into two fuel flows.
(-5B):
The main fuel flow goes through the HMU metering
system, the fuel flow transmitter and fuel nozzle filter and
is then directed to the 20 fuel nozzles.
(-5A, 5B):
The other fuel flow goes to the servo fuel heater, which
warms up the fuel to prevent any ice particles entering
sensitive servo systems.
The heated fuel flow enters the HMU servo-mechanism
and is then directed to the various fuel-actuated
components.
A line brings unused fuel, from the HMU, back to the inlet
of the main oil/fuel heat exchanger, through the IDG oil
cooler.
A Fuel Return Valve (FRV), also installed on this line, may
redirect some of this returning fuel back to the A/C tank.
(-5A):
The main fuel flow goes through the HMU metering
system, the fuel flow transmitter and the fuel nozzle filter
and is then directed to the fuel nozzles and the BSV.

FUEL PUMP
The purpose of the engine fuel pump is:
- To increase the pressure of the fuel from the A/C fuel
tanks, and to deliver this fuel in two different flows.
- To deliver pressurized fuel to the main oil/fuel heat
exchanger.
- To filter the fuel before it is delivered to the fuel
control system.
- To drive the HMU.
The engine fuel pump is located on the accessory
gearbox aft face, on the left hand side of the horizontal
drive shaft housing.
The fuel supply line is routed from a hydraulic junction
box, attached to the left hand side of the fan inlet case,
down to the fuel pump inlet.
The fuel return line is routed from the Fuel Return Valve
(FRV), along the left hand side of the fan case, and back
up to the hydraulic junction box.

oil general
(-5B):
The oil system is self contained and may be split into the
different circuits listed below:
- Oil supply circuit.
- Oil scavenge circuit.
- Oil circuit venting.
The oil is pumped from the oil tank by the supply area of
the lubrication unit. Before entering the unit, the supply
oil passes through the anti-siphon, which prevents the oil
tank from getting emptied at engine shutdown.
After being filtered, the oil is supplied to the engine
sumps by three supply lines leading:
- To the forward sump.
- To the rear sump.
- To the AGB-TGB.

oil tank
The oil tank stores the engine oil and is installed on the
fan case, at the 8 oclock position, on one upper and two
lower mounts with shock absorbers.
The tank has an oil inlet tube from the exchanger, an oil
outlet to the lubrication unit and a vent tube.
To replenish the oil tank, there are a gravity filling port, a
remote filling port and an overflow port.
A scupper drain ducts any oil spillage to the drain mast
and a plug is provided for draining purposes.
The tank has a pressure tapping connected to a low oil
pressure switch and oil pressure transmitter, that are
used in cockpit indicating.
Between engine start and running conditions, the oil level
drops, due to the gulping effect.

anti-siphon
The anti-siphon device prevents oil from the oil tank being
siphoned into the accessory gearbox, during engine
shutdown.
Oil from the oil tank flows across the anti-siphon device,
through its main orifice.
During engine operation, the downstream oil pressure
from the supply pump enters the anti-siphon device,
through a restrictor.
During engine shutdown, sump air is able to enter the
anti-siphon device and inhibit the oil supply flow.
