Question

Which of the following is correct?

(a) We can generate flat wrap surface by using linear interpolation method

(b) Flat surfaces can only be generated by using linear interpolation

(c) Linear interpolation will never give flat surface

(d) Linear interpolation is only used for flat wrap surfaces

I have been asked this question in unit test.

Asked question is from Configuration Layout topic in division Configuration Layout and Loft of Aircraft Design

Answer 1

Correct choice is (a) We can generate flat wrap surface by using linear interpolation method

To explain: A flat wrap surface has same tangent angles for different conic curves. When linear interpolation method is used, it does not always provide constant cross-sections or c/s with same tangent angles. Hence, it may or may not produce flat wrap. We can generate flat wrap by providing some constraints as well.
