Airframe Flashcards
Fundamentals
Purpose of Hydraulic Fluid Contamination Analysis
Determining fluid containment level
Purpose of tactical paint scheme
Lessen visual and photographic detection
Purpose of NAVAIR 509
Prevent, control, repair corrosion
Purpose of NAVAIR IETM
Support diagnostics, maintenance, repair of aircraft
Three modes of wheel brake operation
Normal, emergency, parking
Purpose of composite airframes material
Limit weight, increase strength, decrease effect of corrosion attack
Temporary repair
Repair to allow aircraft to fly until a permanent repair is made
One time flight repair
Repair made to fly aircraft to repair station (one time)
Permanent repair
Made to meet or exceed strength of structure or component
Radome
Covers radar and window for transmission and reception of radar signals
Forward Fuselage
Front of aircraft (radome-canopy)
Center fuselage
Main landing gear-AMAD and Intake ducts
Aft fuselage
exhaust-engine-stabilators
Wings
Provides lift
Leading edge extension
added lift for high angles of attack
Ailerons
Produces roll
Leading Edge Flaps
Changes lift and produces roll
Trailing Edge Flaps
Changes lift and aids in roll
Stabilators
Produces Pitch and roll on tail end
Rudders
Increase lift and stability and produce yaw
LEX spoiler
Speed brake
Hydraulic Systems
HS1- Provides hydraulic fluid pressure to flight controls
HS2-Primary or secondary source also supplies pressure to non flight control system
APU accumulator-Gas charge cylinder provides fluid pressure to APU
Switching valves- Backup hydraulic pressure to replace primary hydraulic pressure
Landing gear
nose, main, wheel brakes, launch bar, arresting hook
Electronic flight control system
two flight control computers, surface servo actuators, air data and inertial sensors and control sensors
Emergency extension of landing gear
Supplied by APU and emergency brake to unlock landing gear
