Principles of Aerodynamics - Angles of Attack

Question 1

Chordline

Answer 1

straight line from the tail end of the wing to the front of the wing

Question 2

Relative Wind

Answer 2

The manner or angle in which the wind is blowing

Question 3

Angle of Attack

Answer 3

The angle between the relative wind and the chordline.

The angle of attack determines lift of the aircraft, or rather the angle at which it will ascend.

Question 4

Rules to Angle of attack

Answer 4

• The steeper the angle of attack the steeper it will climb
• Their is a limit to the angle. If it goes over your plane will stall.
• Weight does not affect the angle of Attack
• Too steep of an angle of attack means wind separates from the wing

Question 5

Critical Angle of Attack

Answer 5

The critical angle of attack refers to the point in which the angle of the wing is to steep causing the plane to stall
