1
Q
Taper ratio =
A
Root
2
Q
Aspect ratio =
A
Span
(average) chord
3
Q
Sweep wing =
A
Area
4
Q
Sweep angle is measured how
A
Angle between a lateral line and the sweep of the wing 25% back from the LE
5
Q
Rigging/incidence angle
A
The angle between the longitudinal axis (dropped down) and the chord
6
Q
What is MAC
A
A rectangular wing of this chord would show similar pitching moment characteristics of the swept wing
7
Q
What is wash out? where does it reduce the angle of incidence
A
A slight twist in the wing to reduce the angle of incidence meaning it’s lowest at the wing tip
8
Q
What is Dihedral?
A
Wings that tips are higher than root
9
Q
What is Anhedral?
A
Think A - tips that are lower than the root
10
Q
What is included when talking about wing span?
A
the fuselage
