Drag Flashcards
1
Q
Effect of sweepback on drag
A
Wingspan is reduced, AR is reduced, induced drag increases
2
Q
CDi varies with
A
CL squared
3
Q
Effect of vortex generators on drag
A
Increase it as they reenergise the boundary layer
4
Q
What creates more induced drag, elliptical or rectangular
A
Elliptical
5
Q
What can be read from the drag polar
A
Min glide range and the parasite drag coefficient
6
Q
Wing for best L/D ratio
A
Clean wing
7
Q
Flap settings that effect the lift to drag ratio the most
A
30 to 45 degrees
8
Q
Wave drag is made up of
A
Energy drag and flow separation drag
