Sample Questions

Question 1
What is defined as the distance an aircraft propeller would advance in one revolution through a solid, non-yielding medium?
Geometric pitch
Effective pitch
Slip distance
Angle of attack
Question 2
An aircraft propeller has a geometric pitch of 72 inches. During steady cruising flight, the propeller actually advances 54 inches per revolution. What is the propeller slip and percent slip?
Slip is 18 inches, Percent slip is 25%
Slip is 18 inches, Percent slip is 33.3%
Slip is 12 inches, Percent slip is 16.7%
Slip is 24 inches, Percent slip is 30%
Question 3
Which aerodynamic turning moment acts on a rotating propeller blade to rotate the blade toward a higher blade pitch angle (coarse pitch)?
Aerodynamic Turning Moment (ATM)
Centrifugal Turning Moment (CTM)
Thrust Bending Moment
Torque Bending Moment
Question 4
Why is Centrifugal Turning Moment (CTM) generally greater than Aerodynamic Turning Moment (ATM) under normal operating engine speeds?
Centrifugal forces acting on blade mass elements create a high rotational moment seeking alignment with the plane of rotation, overcoming aerodynamic forces
Aerodynamic forces decay to zero whenever the propeller blade is operating at cruise speed
CTM and ATM act in the exact same direction, so CTM adds directly to ATM strength
ATM only occurs when the engine is operating at negative pitch angles during ground reversing
Question 5
In a constant-speed governor, flyweight centrifugal force is governed by the formula F = m * omega^2 * r. If engine rotational speed (omega) increases by 20%, by what percentage does the flyweight centrifugal force increase?
44%
20%
40%
80%
