14
Q
A

Fixed pitch only has one built in blade-angle and can’t be pilot controlled Variable pitch- Has a blade angle that can be changed by the propeller and is controlled with a governor that maintains constant speed

16
Q
A

Blade angle increases to prevent overspeed

17
Q
A

Boost engine oil pressure before entering propeller hub senses rotational speed of propeller, then adjust oil flow to the hub to change pitch

18
Q
A

Centrifugal force acting on the weights causes the blade angle to increase

19
Q
A

Governor is not accelerating or decelerating and the speeder spring and flyweight forces are in balance

20
Q
A

Releasing oil pressure in the governor, counterweight and feathering spring move the propeller into feather. Happens automatically when governor oil pressure drops to zero (following engine failure) Or it can be manually done by the pilot but must be done quickly to reduce chance of windmilling and destroying the engine

21
Q
A

Oil accumulator used to provide oil pressure to unfeather a propeller.

22
Q
A

Alpha- normal operating range of propeller in flight ( course and fine pitch) Beta range- propeller operating in minimum, zero and reverse thrust. Used on ground
