Chapter 10 Flashcards
What wing shape is the ideal pattern for span wise distribution of lift?
elliptical lift is the ideal pattern because the majority of the lift is created inboard.
Which wing design creates the largest tip vorticies and greatest downwash towards the tip?
The rectangular wing design
What is wing loading measured in?
Kg/m2
What effect does aspect ratio have on the CL Alpha curve?
A higher aspect ratio wing produces a steeper curve and a smaller critical angle of attack.
How do you minimise induced drag in a wing design
Any design which distributes the lift across the wing to minimise lift at the wing tip will reduce induced drag.
Which aspect ratio is more efficient?
Higher aspect ratio wings produce weaker tip trailing vortices and there for are more inherently efficient than low aspect ratio wings.
What taper ratio can reach the efficiency of a elliptical wing design
A taper ratio of 0.5 can approach the efficiency of an elliptical wing design.
What wing platform creates more downwash towards the wing tip?
The rectangular wing platform
What is wing loading?
The weight per unit of the wing area.
