Rotor Systems Flashcards
Which component in the rotor system uses commands from the FCC’s of the DAFCS to provide input to the rotor system?
LCTs
What component of the centrifugal droop assembly pulls the balancing arm outward as the NR increases from the ground to flight?
Interposer block (the weight on the balance arm)
What does a rotor blade drooping significantly lower than the other blades possibly indicate?
Missing droop stop
What Flight condition must be avoided if lightning cables and straps are damaged or missing from the rotor blade?
Observed or anticipated lightning strikes
Which component controls the rate and limit the amount of lead and lag for the blade assemblies?
Blade shock absorber
Name the three types of oil hubs on the rotor head and describe what they lubricate
Central oil tank- horizontal hinge pins
Pitch varying shaft tanks- pitch varying bearings
Vertical hinge pin tanks- vertical hinge pin bearings
Which component is mounted inside the pitch shaft, passes through the horizontal hinge pin, and connects to the outboard end of the pitch varying housing?
Tie Bar
Name the six major components of the rotor head
Rotor hub
Horizontal hinge pin
pitch varying shaft
tiebar
Vertical hinge pin
Pitch bearing housing
What components provide rotor speed indications to CAAS?
Speed sensor in the #1 And #2 AC Generators(Permanent Magnet Generator)
Name the four major components that make up the swashplate assembly?
Rotating ring, spherical ball, bearing, stationary ring
Describe the purpose of the fixed droop stops
To limit the amount of flap up and flap down on each blade
What is the purpose of the Kevlar filament windings on the rotor blade?
To secure the shock absorber bracket to the spar
What component of the rotor head allows the blades to lead and lag?
Vertical hinge pin
The slider shaft of the rotor system is made out what material?
Tungsten carbide
What is the purpose of the fixed links in the rotor system?
To measure the stress on dynamic components and provide data for the CGI
