Gas Turbine Control And Operation Flashcards
When you press the on switch, which valve opens?
Spar
How long should you wait between trying to start an engine again?
15minutes,
DC/AC electric starter motor drives the engine through a reduction gearbox. Power is normally transmitted to the LP/HP compressor shaft through the radial drive shaft.
DC Hp
A low stagnating RPM - no EGT rise - no fuel flow indicate what type of start?
Dry start
Low RPM - low fuel flow - high EGT indicates what type of fuel flow?
Hung start.
An excessively quick rise in EGT indictaes what ype of start?
Hot start.
Low RPM - no EGT rise - some fule flow indicated what type of start?
Wet start.
The fuel pump on the auxiliary gearbox of a gas turbine engine is a (1) _____ pressure pump and is driven by the (2) _____ pressure compressor.
High high
In order to relight an engine, what altitude and speed must you be below?
25000ft and 250kts
Engine Pressure Ratio (EPR) compares the pressure rise in the blank with static pressure in the blank
Exhaust - intake
The engines will provide thrust in a worst case scenario – high altitude and high take-off mass. This is also known as blank.
De-rating
Engine blank is when one or both spools stop rotating
Seizer
