8729lbs for takeoff and 9220lb for APR
|
|
|
The engine includes the following rotating assemblies
|
High pressure spool consisting of a 14 stage axial compressor driven by a two stage turbine and a low pressure spool that directly drives the fan through a four stage turbine
|
|
|
The combustion chamber is an
|
Flow through annular type
|
|
|
The combined engine thrust output from the fan and tailpipe is
|
80% from the fan and 20% from the tailpipe
|
|
|
The inlet guide vane system consists of
|
An inlet guide vane and variable stator vanes on the first five compressor stages
|
|
|
The accesxory gearbox (AGB) on each engine has the following components mounted on it
|
Starter, hydraulic pump (1A,2A), oil pressure/scavenge pump assembly, IDG generator, fuel pump/fuel control unit, and alternator
|
|
|
Engine thrust is controlled by
|
A hydromechanical governor when below 79% N1 and a fuel computer (ECU) at higher N1 speeds
|
|
|
Selecting a thrust lever to SHUT OFF position mechanically.
|
Closes the shutoff valve in the fuel control unit
|
|
|
Normal idle N2 is
|
Variable with temp so that 575lbs thrust is produced
|
|
|
The engine fuel computer (ECU) is powered by
|
An alternator driven by the accesory gear box

The oil replenishment system in the aft equipment bay
|
|
|
Thrust reverser stowing by the pilot
|
Is electrically accomplished independent of the related THRUST REVERSER switch by pusing down on the related thrust reverser lever

|
|
The thrust reversers are the _________ and aid in aircraft deceleration by ________?
|
Cascade type; redirecting only fan air forward
|
|
|
Pushing EMER STOW switchlight
|
Bypasses normal/automatic control circuits to apply a stow signal to the PDU air valve and releases the PDU brake and flex cable lock
|
|
|
Engine vibration is indicated by
|
The amber VIB icon in the N2 scales or amber readout in the ENG VIB display without master caution alerting
|
|
|
The red HOT icon appears in the ITT scale when ITT
|
Is above 500c and increasing faster than 200c/per second
|
|

|
10th stage bleed air valve open supplying one pack, plus cowl or wing/cowl anti icing on
|
|
|
Climb and cruise thrust settings with cowl or cowl/anti icing on are provided up to what pressure altitude
|
30,000ft
|
|
|
The APR ARM advisory EICAS message appears for five minutes if
|
Both engines are above 79% N1, APR switch at ARM, both ENG SPEED switches at ON and aircraft on the ground
|
|
|
An APR event is triggered by
|
Either engine N1 decreasing below 67% while APR ARM advisory EICAS message is shown
|
|
|
Pushing an engine START switchlight
|
Opens the related starter valve, both 10th stage shutoff valves, and the 10th stage isolation valve, and activates the armed ignition
|
