Propeller Quiz

What is the primary function of a propeller hub?

• To reduce drag

• To connect the propeller blades to the aircraft engine

• To enhance the appearance of the aircraft

• To adjust the angle of the propeller blades

Which of the following describes the shape of propeller blades?

• Square and thick

• Circular and rigid

• Curved with a camber

• Flat and straight

What is the purpose of a propeller spinner?

• To increase engine RPM

• To streamline airflow and reduce drag

• To connect the blades to the hub

• To adjust blade pitch

Which type of pitch mechanism allows the pilot to adjust the blade angle during flight?

• Feathering

• Ground-Adjustable Pitch

• Fixed Pitch

• Controllable-Pitch

What is a characteristic of a fixed-pitch propeller?

• The blade angle can be adjusted in flight

• The blade angle is set permanently during manufacturing

• It is used in larger aircraft

• It automatically adjusts to maintain constant RPM

What material is commonly used for propeller spinners?

• Steel

• Plastic

• Wood

• Aluminum or composite materials

What does the twist in a propeller blade ensure?

• Reduced drag at the root

• Increased weight for stability

• Each section meets air at an efficient angle of attack

• Uniform thickness along the blade

Which of the following is NOT a function of a propeller spinner?

• Aesthetics

• Protection

• Increasing engine power

• Aerodynamics

What is the purpose of the propeller pitch control mechanism?

• To connect the blades to the hub

• To maintain a constant speed

• To adjust the angle of the propeller blades for performance

• To reduce the weight of the propeller
