Introduction
April 3, 2017, © Leeham Co.: In the first part of our investigation on how good an NMA can be, we explored low weight and drag fuselage design. We will now continue with the design consequences for the fuselage construction and the cabin. What drives whether one goes for an Aluminum or CFRP (Carbon Fiber Reinforced Polymer) fuselage?

What will be the typical dimensions for an NMA fuselage and what will be passenger capacities? Summary:
  • An elliptical fuselage will force a CFRP design.
  • The fuselage door configuration will be critical for cabin capacity and flexibility.
