ASA Question Review

QuestionAnswer
The pitch changing mechanism in a Hydromatic is lubricated by? the pitch changing oil
On A/C equipped with hydraulic constant-speed props, the magneto and ignition is checked with the prop in what position? high RPM
What occurs to cause front cone bottoming during prop installation? front cone hits shaft splines, preventing both cones from being tightened against the cone seats in the hub
If a flanged prop shaft has dowel pins, how does the prop go on? only one way for it to go on
Where are the pitch stops for a Hamilton Standard prop located? the counterweight assembly
The centrifugal twisting moment of an operating propeller tends to? reduce the pitch angle
What force moves constant speed counterweight props to a high pitch setting? centrifugal force acting on the counterweights
If the tension of the speeder spring is reduced by movement of the cockpit prop control, the blade angle will? increase, manifold pressure will increase, and engine RPM will decrease
If prop cones or hub seats show evidence of wear, the most likely cause is? the prop retaining nut wasn't tight enough during previous operation
What force tends to bend the propeller forward at the tip? thrust bending force
The cones on the splined shaft do what? position the prop onto the shaft
Centrifugal force acting on a prop blade is? greater than the aerodynamic twisting force and tends to move the prop blades to a lower angle
What best describes the blade movement of a full feathering constant speed prop in the low RPM position when it starts feathering? high pitch directly to feather
Automatic prop synchronization is done through the actuation of what? the prop governors
What will happen to the prop blade angle and engine RPM if the tension on the speeder spring increases? blade angle decreases, engine RPM increases
Why is the pulley stop screw on a governor adjustable? limit the max engine speed during takeoff
How is electrical power transferred to the prop assembly from the engine? slip rings and brushes
Prop thrust imbalance can be eliminated by? correct blade contouring and angle setting
Geometric pitch is defined as? geometric pitch plus slippage
A 3-way prop valve does what? direct oil from the engine oil system to the prop cylinder
The primary purpose of a prop cuff is to? increase the flow of cooling air into the engine nacelle
If the engine RPM is lower than what the constant speed prop can govern, the prop will? remain in the full LOW PITCH position
What would make an aluminum prop unrepairable? transverse cracks of any size
What controls the constant speed range of a constant speed prop? the mechanical limits in the prop pitch range
When engine power is increased, constant speed props try to function to? maintain RPM, increase blade angle, and maintain a low angle of attack
How is the speed of a constant speed prop changed in flight? by changing the load tension against the flyweights in the governer
Thrust bending force bends blades forward
Centrifugal twisting force twists blades to a low pitch angle
Aerodynamic twisting force twists blades to a high pitch angle
Centrifugal force pulls blades away from the hub
Torque bending force bends props away from direction of rotation
