Ice Protection
Aircraft electrical power for propeller deicer systems is transferred from the engine to the propeller hub assembly using these.
What are slip rings and brushes?
This piece of equipment supports the propeller on the balance knives.
What is an arbor?
This component on a propeller governor is used to limit the maximum engine speed during takeoff.
What is the pulley stop screw?
This operational force causes the greatest stress on a propeller.
What is centrifugal force?
This system is used to control multi-engine RPM and reduce vibration. What is the propeller synchronizing system?
What is the propeller synchronizing system?
This is the position of the propeller blades when the prop control lever is in the full forward position.
What is the full LOW PITCH position (high RPM)?
This operational force tends to increase propeller blade angle.
What is aerodynamic twisting force?
How are the piston pins of most aircraft engines lubricated?
By oil which sprayed or thrown out by the master or connecting rods.
This unit in the propeller anti-icing system controls the output of the pump.
What is the rheostat?
This type of imbalance will cause a two-blade propeller to have a persistent tendency to come to rest in a horizontal position (with the blades parallel to the ground) while being checked on a propeller balancing beam.
What is vertical?
This operational force tries to twist the blades to a lower blade angle.
What is centrifugal twisting moment (CTM)?
What is the source of most of the heat that is absorbed by the lubricating oil in a reciprocating engine?
Pistons and Cylinder walls.
Having an assistant feeling the sequence of heating and observing the load meter indications is a test for this system.
What are electric deicing boots?
This process may be necessary to achieve final balancing of a wood propeller.
What is the application of more protective coating on one blade than the other?
This component controls the oil to and from the pitch changing mechanism.
What is the propeller governor?
This is the angle formed between a line perpendicular to the crankshaft and the chord line of the blade.
What is Blade Angle?
What is the primary purpose of changing aircraft engine lubricating oils at predetermined periods?
The oil becomes contaminated with moisture, acids, and finely divided suspended solid particles.
Adjusting the phase angle between the propellers on an aircraft's engines is accomplished by this system.
What is the synchrophasing system?
This will happen to the propeller blade angle and the engine RPM if the compression on the propeller governor control spring (speeder spring) is increased.
What is blade angle will decrease, and RPM will increase?
The purpose of a relief valve installed in the tank venting system of a turbine engine oil tank is to
Prevent oil pump cavitation by maintaining a constant pressure on the oil pump inlet.
