AIRCRAFT INCLUDING A PASSENGER CABIN EXTENDING AROUND A SPACE DEFINED OUTSIDE THE CABIN AND INSIDE THE AIRCRAFT

摘要

The sealed bottoms of aircraft passenger cabin have to be fastened with heavily sized fasteners so as to withstand loads induced by the cabin pressurization. Besides, the increase in aircrafts seating capacity makes an increase in passenger cabin widths of interest. Such a width increase however makes the structure delimiting passenger cabin less resistant to efforts induced by the cabin pressurization. The present invention proposes an aircraft wherein the structure delimiting passenger cabin extends over 360 degrees around a space defined outside structure. The invention allows structure to be more resistant to loads induced by the cabin pressurization, while allowing to reduce or even to avoid the need for a sealed bottom, and while allowing to increase the space available for passengers.

主权项

1. An aircraft, comprising a structure delimiting a passenger cabin, wherein when the structure is seen from above, the structure comprises:
at least two lateral portions respectively delimiting two lateral regions of the passenger cabin and separated from each other by a space defined outside the structure and extending between the lower and upper parts of an aerodynamic envelope externally delimiting the aircraft; a forward portion connecting two forward ends of the lateral portions of the structure to each other; and an aft portion connecting two aft ends of the lateral portions of the structure to each other.
