Following graph represents |
| A. | graphical method to find mac |
| B. | graphical method to produce drag |
| C. | graphical method to find lift |
| D. | graphical method to find lift-curve |
| Answer» A. graphical method to find mac | |
| Explanation: above figure is showing the typical graphical method to find the mac. here, first we project the root chord from tip chord and vice-versa as shown by dashed lines from respective chords. after that we draw a line from which will connect midpoints of root and tip chord. intersection of both lines will provide mac which will be located at y distance from root chord as shown. | |
| 52. |
For wing to be lofted as shown in below figure, what will be the approximated value of MAC? |
| A. | 8m from l.e. |
| B. | 8m from t.e. |
| C. | 12m from l.e. |
| D. | 12m from t.e. |
| Answer» A. 8m from l.e. | |

| B. | 2m from t.e. |
| C. | at l.e. |
| D. | at t.e. |
| Answer» A. 2m from l.e. | |
| Explanation: given, mac = 8m location of aerodynamic center = 25% of mac = 25% of 8 = 0.25*8 = 2m from l.e. | |
| 54. |
Which of the following is correct in terms of the wing layout with twist? |
| A. | incidence at each span station must be considered and chord should be rotated accordingly |
| B. | only untwist airfoils can be used for layout |
| C. | only rotation of chord line is required at c/6 points |
| D. | only chord line should be rotated by reducing length of chord |
| Answer» A. incidence at each span station must be considered and chord should be rotated accordingly | |
| Explanation: in general, airfoils are drawn to find the complete wing layout. when wing has some twist then, we need to find incidence at each span station in order to include effects of twist. also chord needs to be rotated accordingly before drawing an actual airfoil for lofting. | |
| 55. |
Which of the following is correct? |
| A. | generally, tip airfoils are selected for stall characteristics |
| B. | always root airfoils are elected for stall characteristics |
| C. | wing twist will increase thrust by engine |
| D. | wing twist is not considered for layout |
| Answer» A. generally, tip airfoils are selected for stall characteristics | |
| Explanation: generally, tip airfoils are selected for gentle stall properties. root airfoils are selected for best performance. by doing so we will have better wing which has overall good performance and stall properties. | |
| 56. |
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. | |
