15.10 Flashcards
What does the lubrication system do
Distribute oil to the engine bearing compartment and gearbox
What type of lubrication system do most gas turbine engines use
A self contained dry sump lubrication system
What happens to the oil before it reaches the oil nozzle
The oil Is filtered
What does the scavenge system do
Oil Returns the oil the bearing compartment and gearbox to oil tanks
What does the vent system do
Release air from the lubrication system to the atmosphere
How is the oil tank connected to the vent system
Via a vent line
How does the vent system provide air to the gearbox
Via the radial drive shaft housing
What do mechanical clogging indicators sense
Clogged filters also known as pop out indicators
What can you use to inspect the filters
Magnetic chip detectors
What does EIU stand for
Engine Interface Unit used to send info via a computer
What are the two types of oil quantity transmitter
The capacitance type
The reed switch type
What are the two types of oil temperature sensors
Thermocouple and thermistor
What process is used to find out about the internal wear of a lubricated engine component
SOAP, Spectrometric Oil Analysis Program
What size particles can the SOAP process catch
0.001-0.02mm
What size particles can the scavenge oil filter catch
More than 0.015mm
On engines without an anti-siphon what time period should you check the oil quantity after engine shutdown
Between 5-20mins
What does a fuel smell In a oil filter indicate
Leakage in the fuel cooled oil cooler
What is the process Calle when filling the oil with oil cans
Gravity filling
What is the process called when you use an oil servicing system to refill the oil
Pressure filling
Why should you use transparent horses for the overflow port of the oil servicing system
So that you can see when the tank is full
Where are oil samples taken from for SOAP
From engine oil tank
Some magnetic chip detector have two seals what are the two types of seal
Reusable seal
O-Ring
