Chapter 3

Initial Sizing

Abstract

Powerful methods to perform the initial sizing of the airplane are presented. Starting with definition of cost, effectiveness, and cost-effectiveness, the chapter then presents a powerful method, called Constraint Analysis that helps the designer determining the W/S and T/W (or P/W) for the new design such that it will meet all prescribed performance requirements. This is followed by an introduction to various trade studies tools. Trade studies comprise methods that offer powerful approaches for the solution of various engineering problems. This includes carpet plots, design of experiments, and cost function approaches.
