1. what is the primary function of a initiates the rotation of the compressor for engine start
starter in a gas turbine engine
2. what initiates the starter in a tur- cockpit toggle switch
bine aircraft
3. at what RPM does the starter typ- 5-10% rpm
ically shut itself off
4. What spool does the starter spin N2 (high pressure compressor)
on dual and triple spool com-
pressors?
5. what are the two types of com- fluid wash and abrasive grit blast
pressor cleaning
6. what are the two methods of motoring the engine with starter only or while engine is
compressor wash running
7. what engine speed/pressure is a 14-25% with a cleaning mixture pressure of 30 to 50 psi
motoring wash performed at
8. what engine speed/pressure is a 60% with a cleaning mixture and rinsing solution pressure
running wash performed at of 15-20 psi
9. what is carboblast made of walnut shells and apricot pits
10. when should a power recovery every 100-200 hours, when power decrease is noted
compressor wash be done
11. how often should compressor daily
washes be done on an engine
operating continuously in a salt
laden environment

12. how often should compressor weekly
washes be done on an engine op-
erating in occasionally salt laden
conditions
13. what are 7 types of starters cartridge pneumatic starter
talked about in class high/low pressure pneumatic starter
pneumatic (air turbine) starter
electric starter
fuel/air combustion starter
turbine impingement starting
starter generator
14. how does the starter prevent drive shaft shear point and controlled overspeed stabiliza-
damage to the engine during op- tion
eration
15. what kind of starter is typically electric starter
used in an APU/GPU
16. why are electric starters not com- heavy compared to other styles
monly used on aircraft engines
17. what is the advantage of pneu- lighter and high power to weight ratio
matics starters over electric
starters
18. what kind of starter is used on a starter generator
turbo prop
19. what is the primary advantage of reduces weight, more feasible for smaller engines
using a starter generator
