p3b4 Flashcards
primary purpose of 400 division
perform 1st, 2nd, and 3rd degree maintenance on gas turbine engines and related components
types of engines that FRC’s repair
T56-A-14 - quick engine change kit
T56- engine
propellor assy
concept of a modular engine
increases the ability to replace parts at the lowest level
5 major sections of an engine
- power
- compressor
- turbine
- torque meter
- reduction gear
first degree engine repair
compressor and rotor
second degree engine repair
turbine and combustion
third degree engine repair
all repairs, high maintenance hours
blend
filing and polishing damage sections
crack
concentrated stress
bow
smooth repair into contour of surrounding area
dent
small smoothly rounded hollow
gouge
displacement of material from a surface
growth
elongation of a blade
engine FOD
ingestion of objects not organic to the engine
purpose as pertained to engine FOD investigation
determine if changes are needed
how engine fod is reported if found during an investigation
within 5 days or less
responsibilities of frc facilities during an engine fod investigation
must inspect all engines for evidence of fod
objective of gas turbine engine maintenance program
ensure equipment is properly maintained and that all scheduled maintenance is performed
define the screening and induction time limits for non-rfi engines
inducted within 10 working days of receipt
Bernoulli’s principle as it applies to engines
velocity increases while pressure decreases
purpose of engine oil and part number
lube cool and clean

basic purpose of the test cell
perform operational tests or functional checks on rework engines
responsibilities of a test cell operator
perform operational or functional checks on GTETS or GTF
basic components that make up a test cell
- test cab
- control console
- engine connector panel
- instrumentation
- thrust bed
- restraint equipment
- electrical system
discuss the safety hazards associated with test cell operations
- jet blast
- hot exhaust gases
- hazardous noise
- shock hazards
state the program which establishes procedures for training and designating engine test facility operators and qualifiers
- GTETS
- GTF
- operator training
- certification program
periodicity with which fresh water was downs shall be performed and documented on the test facilities and surrounding area
at least once a week ashore and at least once a month afloat
