Abstract: An oblique wing aircraft (1) designed for reduced surface area to volume ratio. The aircraft has an oblique wing comprising a forward swept wing segment (27) on one side of the wing and an aft swept wing segment (29) on the opposite side of the wing. A center oblique airfoil section (25) connects the forward and aft swept wing segments. The center oblique airfoil section has a larger chord near its centerline than the chords of either of the forward or aft swept wing segments. The chord of the center oblique airfoil section tapers down more rapidly than the forward or aft wing segments as the center oblique airfoil section extends outboard toward the forward and aft swept wings. The center oblique airfoil section is not shaped solely to function as a circular fairing to fill the gap between an oblique wing and a fuselage at different oblique wing angles, nor is it a second wing in an X wing configuration. Preferably, the aircraft is an all-wing aircraft.

Abstract: Passenger accommodations are easily and rapidly convertible from conventional seats to bunk beds and back. A support structure (9) supports a seat pad (13) and a seat pad extension (15) and also rotatably supports a seat back (5). The seat pad extension (15) and seat back (5) are partially supported by the support structure (9) of a row of seats ahead of the convertible seats when the convertible seats are converted to bunk beds. A third bunk bed (21,23) may be unfolded under the lower bunk bed formed by the seat pad (13, 15).
