Dry sump lubrication system used in

most modern gas turbine engines.

Film lubrication

is a measurable film of oil between moving parts.

In a full flow oil system the pressure relief valve opens in

over pressure situation

The oil pressure regulator is

a spring loaded adjustable valve

Scavenge pump and filter is larger than pressure pump and filter

to accommodate oil expansion and foaming after passing through the bearing chamber

1 pressure pump and

7 scavenge

Oil supplied from tank to pressure pump by

gravity

Oil tank float valve

prevents oil loss if cap isn’t installed

Centrifugal Breather separates

oil from air inside gearbox using centrifugal force.

The purpose of a deaerator tray which located in the top of the oil tank

to remove air from the oil

Gas turbine engines bearings are lubricated in one of the following ways

Spray jet, pressure, fed Splash oil and Metered oil Film Lubrication

Bearing lubrication type used to minimize the effect of the dynamic loads is a

squeeze film.

Thread filter used to protect

oil pressure spray nozzle

Thread filter located

just before bearing chamber

Thread filter

cleaned only in engine overhaul

FCOC located either in

pressure sub-system or in scavenge sub-system.

Some large engines have secondary air-oil cooler used in

a high power condition.

Thermostatic valve in the fuel oil heat exchanger used to

regulate the flow of oil through the heat exchanger

Hot-Tank System

oil cooler in the pressure line, scavenge oil does not cooled before tank

Gas turbine engine use

wet and dry sump lubrication system

Wet sump lubrication system engines store the lubricating oil in

the engine property

The AMM will prescribe time limits to replenish the oil system

typically not before 10-minutes after shut-down and not longer than 1 hour

When pressure or scavenge oil filter have mechanical or electrical pop out indication in the event of

blockage or cold starting

Turbine engine oil pressure pump is normally

gear type pump

A scavenge screen filter are coarse mesh fitted individual scavenge line used to

catch large debris that may have come from the bearings

siphon action down

Pulse chip detector contains

a pulsating mechanism by the aircraft 28vdc bus
