Question

Aircraft production cost can be reduced by using _____________

(a) flat wrap surfaces

(b) non-flat surface

(c) more forging processes

(d) welding only on non-flat surfaces

I had been asked this question during an interview for a job.

This interesting question is from Configuration Layout topic in division Configuration Layout Considerations of Aircraft Design

Answer 1

The correct choice is (a) flat wrap surfaces

To explain I would say: Flat wrap surface is used to reduce the effort and cost of the structure. In flat wrapping, we can directly wrap a sheet on our surface. This can significantly lower the aircraft production cost.
