1
process of working a metals surface to “improve” its material properties. usually by mechanical means such as hammer blows or shot peening “relieves stresses in metal surfaces, prevents stress related failure of part”
2
intensity (speed), time of peening
3
Has captive shot embedded in rubberized fabric flaps “Tungten Beads”
4
by propelling balls onto the part via ultrasonic excitation. “introduces compressive stresses deeper than traditional shot peening for increased fatigue life”
5
N strip = .031” A strip = .051” C strip = .094”
6
almen gage
7
1. flap rotation speed RPM 2. peening time 3. mandrel height
8
internally protected evenly with corrosion inhibiting fluids or inert gases ex. linseed oil, water displacing compounds, inert gases “nitrogen”
9
should the frame crack and gas leak out, a drop in pressure will be detected. allows stressed components to be monitored
10
accurate proportioning and thorough mixing of the two components are very important to ensure complete and even cure
11
yes. temperature and humidity affect curing of sealant and type of sealant to be used on aircraft.
12
used for filling small pockets of aircraft structures to aid in the drainage of water and other fluids.
13
1. corrosion 2. damage to leveling compound
14
light duty “oil- like” having ability to displace water and wick faying surfaces, cracks “provides a wet non-drying thin protective coating of one mil 0.025m”. not long lasting protection
15
1. pliable sealants 2. drying sealants 3. curing sealants
16
the length of time the material may be stored and used without its integrity being affected
17
1. when sealant does not cure or takes too long to cure 2. marbleized (streaky) sealant is caused by incomplete mixing. base material will not cure 3. surface must be clean for sealant adhesion. unwanted moisture from contaminated surface can cause corrosion.
18
used to spread sealant “uniformly” over the entire surface to desired thickness (typically 10 to 15 mils)
19
1. water displacing 2. non-water displacing
20
1. electrical connectors 2. control cables 3. pulleys 4. teflon bearings
