do you like aerodynamics?

Question

Incorporating wing twist into wing design creates ……..
a)higher angle of attack at the wing tip than wing root.
b)Lower angle of incidence at the wing tip than wing root.
c)lower angle of attack at the wing root than wing tip.
d)a&c
plz pay attention to " wing design" & its subsequences.....

Answer 1

Wing twist is used to lower the angle of attack at the outboard end of the wing to help maintain aileron control effectiveness during slow flight or during a stalled flight condition.

Therefore, a) is out of the question. d) is also therefore out.

c) is out of the question since the twist will lower angle of attack at the wing tip for the reasons I mentioned.

My answer is b), because:

Angle of incidence refers to the physical angle at which the wing lies in relation to the longitudinal axis of the aircraft. With the twist incorporated into the wing, the outboard portion of the wing (with the twist) will be at a lower angle of incidence than the wing root. I dislike the wording of the answer, as it should be "lower angle of attack at the wing tip" - but it is still the correct answer.

Answer 2

Yes, I like aerodynamics!

But are we answering your class test questions? We dont see much Multiple Choice Questions in the Yahoo Answers.

Answer 3

great speed great wind current
cool looking design
yes, i like aerodynamics

Answer 4

Anything wind the word aero or air, i dont like it. cause i'm afraid of heights.

Answer 5

yes when im flying i like aerodynamics

Answer 6

yup
love it!!!
