Additional Components and Systems Flashcards
On a FADEC jet engine, the meaning of F.A.D.E.C. on a gas turbine engine is?
Full Authority Digital Engine Control
On most high by-pass ratio (fan) engines, reverse thrust is achieved by reversing?
Only the direction of the fan airflow.
In an engine equipped with dual channel FADEC, what happens in the event of total FADEC failure?
The engine will fail.
The fuel-oil heat exchanger of a gas turbine engine does?
Cools the oil and heats the fuel.
The continuous ignition mode of a gas turbine engine is a?
Low-energy-level ignition used when there is an increased risk of a flame-out.
On a FADEC gas turbine engine during normal flight, the power for the FADEC’s sensors comes from?
The FADEC power source(s) on the engine.
How is the auxiliary gearbox driven and lubricated?
From the high compressor and is connected to the engine lubrication system.
The shear neck is a device fitted to prevent?
Engine failure, in case of mechanical failure of the gearbox.
For a turbine engine, the self-sustaining speed relates to the minimum RPM at which the engine?
Will continue to operate without any starter motor assistance.
How is an auxiliary gearbox lubricated?
With oil.
The accessory gearbox of a fanjet engine is driven by?
The high pressure shaft.
Labyrinth seals in the lubrication system of a gas turbine engine are designed to provide a seal that is?
Not completely tight, allowing some movement between rotating and static parts.
An auxiliary gearbox is driven by?
A rotating engine shaft, via an internal gearbox, to an external gearbox.
The purpose of a chip detector in the oil system of an engine/gearbox is to indicate that?
There are metal particles in the oil.
The primary reason for venting an engine oil tank is to?
Prevent excessive pressure in the tank.
What does the Electronic Engine Computer (EEC) primarily control in an aircraft?
Fuel and engine functions.
