Warm-Up – 11/20 – 10 minutes

Basic Propeller Principles• The aircraft

propeller consists of two or more blades and a central hub to which the blades are attached.

• Each blade of an aircraft propeller is essentially a rotating wing.

Utilizing your notes and past knowledge answer the following questions:

1) An aircraft propeller functions like a _______ _____?

2) Which edge of a propeller blade hits the relative wind first?

3) How is pitch of a propeller measured?4) True / False - the area of decreased pressure

is in front of the propeller, and the force (thrust) is in a forward direction.

5) What design factor is utilized on a propeller blade to keep thrust more nearly equalized along this length?

Warm-Up – 11/20 – 10 minutes

Basic Propeller Principles• The chord line is

an imaginary line drawn through the blade from its leading edge to its trailing edge.

• As in a wing, the leading edge is the thick edge of the blade that meets the air as the propeller rotates.

Utilizing your notes and past knowledge answer the following questions:

1) An aircraft propeller functions like a _______ _____?

2) Which edge of a propeller blade hits the relative wind first?

3) How is pitch of a propeller measured?4) True / False - the area of decreased pressure

is in front of the propeller, and the force (thrust) is in a forward direction.

5) What design factor is utilized on a propeller blade to keep thrust more nearly equalized along this length?

Warm-Up – 11/20 – 10 minutes

Basic Propeller Principles

• The pitch is the distance in inches, which the propeller would screw through the air in one revolution if there were no slippage.

Utilizing your notes and past knowledge answer the following questions:

1) An aircraft propeller functions like a _______ _____?

2) Which edge of a propeller blade hits the relative wind first?

3) How is pitch of a propeller measured?4) True / False - the area of decreased pressure

is in front of the propeller, and the force (thrust) is in a forward direction.

5) What design factor is utilized on a propeller blade to keep thrust more nearly equalized along this length?

Warm-Up – 11/20 – 10 minutes

Basic Propeller Principles• The airflow over

the wing has less pressure, and the force (lift) is upward.

• Instead of a horizontal plane, the area of decreased pressure is in front of the propeller, and the force (thrust) is in a forward direction.

Utilizing your notes and past knowledge answer the following questions:

1) An aircraft propeller functions like a _______ _____?

2) Which edge of a propeller blade hits the relative wind first?

3) How is pitch of a propeller measured?4) True / False - the area of decreased pressure

is in front of the propeller, and the force (thrust) is in a forward direction.

5) What design factor is utilized on a propeller blade to keep thrust more nearly equalized along this length?

Warm-Up – 11/20 – 10 minutes

Basic Propeller Principles

• Propeller blades are twisted to change the blade angle in proportion to the differences in speed of rotation along the length of the propeller, keeping thrust more nearly equalized along this length.
