A blended wing body aircraft having an interior cabin with a usable volume of at most 4500 ftand a cabin aspect ratio of at most 4, wherein a combination of the wings and center body has a wetted aspect ratio of at least 1.7 and at most 2.8. Also, a blended wing body aircraft having an interior cabin with a usable volume of at least 1500 ftand at most 4500 ftand a cabin aspect ratio of at least 2 and at most 4, wherein a combination of the wings and center body has a wetted aspect ratio of at least 1.9 and at most 2.7. Also, a blended wing body aircraft wherein at least each profile section having normalized half-span values from 0 to 0.3 has a leading edge having a normalized height having a nominal value within the range set forth in Table 4.

Blended wing body aircraft

An aircraft is disclosed with a fuselage including a cabin delimited by a cabin floor and having crew quarters. The crew quarters include an upper portion above a floor plane defined by the cabin floor and a lower portion beneath the floor plane. The crew quarters include a seat adjustable between a sitting configuration and a berthing configuration. A method of transitioning a crew member of an aircraft to a berthing configuration in a crew quarters is also disclosed.

Aircraft with crew quarters

A blended wing body aircraft wherein at least each profile section corresponding to the normalized half-span values from 0 to 0.2 has a thickness ratio having a nominal value within the range set forth in Table 1. Also, a blended wing body aircraft wherein at least each profile section corresponding to the normalized half-span values from 0.15 to 0.3 has a normalized chord having a nominal value within the range set forth in Table 1, and wherein a ratio between a maximum thickness of the center body and the chord length along the centerline has a nominal value of at least 16%. Also, a blended wing body aircraft wherein a region of the aircraft defined by normalized half-span values from 0.1 to 0.2 has a normalized chord having a dimensionless rate of change from &#x2212;3.5 to &#x2212;5.1, and a thickness ratio having a rate of change from &#x2212;0.27 to &#x2212;0.72.
