Total Drag & Drag Polar. Flashcards
1
Q
What is Vmd?
A
The speed at where drag is at its minimum.
2
Q
What ratio does Vmd equal?
A
It equals L/D max ratio. (4 degrees)
3
Q
Where is L/D found in a Drag Polar graph?
A
It is found on the Drag Polar graph by drawing a straight line tangent from 0 to the curve.
4
Q
If there is less weight, what will happen to the induced drag and total drag on a Drag Polar graph?
A
Total drag would move down, and left.
Induced would move down, and left.
