Sheet 2 Flashcards
(20 cards)
To convert pressure and heat energy into maximum kinetic energy
A convergent-divergent nozzle
Translating sleeves and blocker doors
Anti-icing and anti-microbiocidal agents
To prevent sludging
High viscosity synthetic oil
Modern gas turbine engines = low viscosity synthetic oil as not heavily loaded gear train
Turbo-prop engines = higher viscosity synthetic oil due to large, heavily loaded propeller reduction gears
Pressure regulated and full flow
In the pressure line, after the pressure pump
A De-aerator
What is used to detect the presence of Ferrous debris in a scavenge return?
(a) Magnetic chip detector
(b) Coarse mesh oil strainers
(c) Last chance oil filters
(a) Magnetic chip detector
Full Authority Digital Engine Control
Plunger and Gear type
15:1
A synchro
With high pressure delivery air
Internal cooling with extensive film cooling
They have a better power to weight ratio than electric starters
Between 18% and 25% RPM
4 joule is supplied by 115V AC and 20 joule is supplied by 28V DC
How are High-Tension ignition leads protected from overheating?
(a) They are located in cool areas of the core engine
(b) They are cooled by Fan air fed into their shrouds
(c) They are wrapped in Asbestos flexi-wap
(b) They are cooled by Fan air fed into their shrouds
