| Q. |
In linear interpolation method, new airfoil is created as |
| A. | weighted average of root and tip airfoil |
| B. | heavier than the root airfoil always |
| C. | higher chord than root always |
| D. | lower chord than tip always |
| Answer» A. weighted average of root and tip airfoil | |
| Explanation: linear interpolation method is used to create new airfoil station between root and tip airfoil. in general, root airfoil is based on performance and tip is selected for stall properties. linear interpolation will give new airfoil as weighted average of the root and tip airfoil. | |
