Day 1 Progress Check Flashcards
What role does the breather system play in turbine engines?
It removes excess air from bearing cavities and returns it to the oil tank
What is the purpose of the Spectrometric Oil Analysis Program (SOAP) in turbine engine maintenance?
To analyze oil samples for the presence of minute metallic elements
What advantage does synthetic oil have over petroleum oil in turbine engines?
Less tendency to deposit lacquer and coke
Which component in the turbine engine lubrication system is responsible for maintaining constant pressure?
Oil Pressure Regulating Valve
What is the purpose of magnetic chip detectors in turbine engine oil systems?
To catch and detect ferrous particles in oil
What distinguishes the gear-type oil pump from the gerotor-type oil pump in turbine engines?
Gear-type oil pumps are most commonly used and consist of two elements: pressurizing and scavenging.
What is the main function of the oil jets/nozzles in a turbine engine?
To deliver oil in the form of an atomized spray to bearings
What is the primary function of the accessory section in turbine engines?
Provides mounting space for components that support operation
How is the oil temperature regulated in large turbofan engines?
Employing a fuel-oil heat exchanger
Which of the following is a characteristic of dry-sump lubrication systems?
Utilizes an external tank for oil storage
