(c) To test model in Fluent

(d) To provide manufacturing

I got this question by my college professor while I was bunking the class.

This interesting question is from Conceptual Design Process topic in chapter Design Process Overview of Aircraft Design

Answer 1

Correct choice is (a) To provide data for initial layout

The best explanation: During the conceptual stage we make a rough sketch called a conceptual sketch. With the help of it we can provide initial estimation of some parameters such as aerodynamics, weight etc. This initial estimation will provide data for the initial layout. Thus, it is called as first order sizing.
