Horizontal double bubble aircraft design for the middle of the market

Abstract

The design of a horizontal double bubble aircraft for the middle of the market appears as a possible solution for the middle of the market segment, allowing to increase the number of passengers per row of seats and opening the way for new concept designs. The possibility of entering this market niche means a big opportunity for airliners. The design proposed offers new structural possibility as well as an improvement in the use of cabin space giving passengers more comfortable seats and a quitter and more efficient trip. After the design phase, the weight estimation will be carried out in depth, covering the entire structure of the aircraft, and the different systems that make it up. This step together with the computational fluid dynamic analysis of the aircraft wing, obtaining the values of the main aerodynamic forces will be of vital importance to evaluate the feasibility, the aerodynamic efficiency, and the range of the aircraft. At the end of the project, the conclusions of the project and possible future works and improvements will be stated
