Abstract: One embodiment is a system (300) comprising fuel tank (310) comprising a pressure vessel for storing fuel for a vehicle, the fuel tank (310) disposed within a fuselage (302) of the vehicle and extending a majority of a length of the fuselage (302), wherein a center of gravity of the fuel tank (310) is substantially aligned with a center of gravity of the fuselage (302). The fuel tank (310) may be disposed within the fuselage (302) such that the fuel tank (310) bears at least a portion of a load borne by the fuselage (302). Alternatively, the fuel tank (310) may be disposed within the fuselage (302) such that the fuel tank (310) is isolated from loads borne by the fuselage (302). In certain embodiments, the fuel tank (310) comprises a filament wound pressure vessel.

Abstract: An airframe for a tiltrotor aircraft (10) includes a wing airframe (24; 106) including a rib (20a, 20b; 124a, 124b), a fuselage airframe (26; 102) including a fore-aft overhead beam (28a, 28b; 126a, 126b) and a cradle support assembly (56a, 56b; 110a, 110b). The cradle support assembly (56a, 56b; 110a, 110b) includes a forward wing support (146a, 146b) coupled to the fore-aft overhead beam (28a, 28b; 126a, 126b) and the wing airframe (24, 106) and an aft wing support (148a, 148b) coupled to the fore-aft overhead beam (28a, 28b; 126a, 126b) and the wing airframe (24, 106). The rib (20a, 20b; 124a, 124b), the fore-aft overhead beam (28a, 28b; 126a, 126b), the forward wing support (146a, 146b) and the aft wing support (148a, 148b) are substantially aligned to form a wing-fuselage integrated airframe beam assembly (32a, 32b; 108a, 108b) to support the wing airframe (24, 106).

Abstract: According to one embodiment, an aircraft features a fuselage (130), a wing member (150), and two fuselage beams (220a, 220b). The fuselage (130) features a first plurality of structural supports, a second plurality of structural supports, a first opening (132a) disposed between the first plurality of structural supports, and a second opening (132b) disposed between the second plurality of structural supports. The wing member (150) is disposed above the first opening (132a) and above the second opening (132b). The wing (150) features a plurality of ribs (152) including a first rib (152a) and a second rib (152b). The first fuselage beam (220a) couples the first rib (152a) of the wing member (150) to the fuselage (130) and has an elongated body portion extending across the first plurality of structural supports. The second fuselage beam (220b) couples the second rib (152b) of the wing member (150) to the fuselage (130) and features an elongated body portion extending across the second plurality of structural supports.

Abstract: One example of a tiltrotor aircraft (100) includes a rotor system (110a, 110b), a pylon (102a, 102b) coupled to the rotor system (110a, 110b), a spindle (112) coupled to the pylon (102a, 102b), an actuator arm (114) coupled to the spindle (112), and an actuator (116). The actuator (116) can cause the actuator arm (114) to rotate, thereby causing the spindle (112) to rotate the pylon (102a, 102b) and the rotor system (110a, 110b). In an example, the actuator (116) is in front of a forward spar (122) of the wing (104) of the tiltrotor aircraft (100) and the actuator arm (114) is about one-half (0.5) of an inch (1.27 cm) to about five (5) inches (12.7 cm) from the wing (104).

Abstract: A wing airframe (20) for a wing (18) of a tiltrotor aircraft (10) includes a wing airframe core assembly (46) and a wing skin assembly (26) disposed on the wing airframe core assembly (46). The wing skin assembly (26) includes a lower wing skin assembly (48) disposed on the bottom side of the wing airframe core assembly (46). The tiltrotor aircraft (10) includes a fuselage (12) underneath the wing (18). The lower wing skin assembly (48) has one or more buckle zones (42, 44) outboard of the fuselage (12). The buckle zones (42, 44) are locally susceptible to buckling in response to an impact of the tiltrotor aircraft (10), thereby protecting the fuselage (12) from being crushed by the wing (18).

The airframe assembly (50) includes a first airframe member (214) having a first skin (202), a second skin (210), a large cell core (204) joined between the first (202) and second (210) skins and a solid insert (208) having a side surface. The solid insert (208) is joined between the first (202) and second (210) skins such that at least a portion of the side surface is adjacent to the large cell core (204). The first skin (202) has a first surface disposed opposite the solid insert (208). The airframe assembly (50) also includes a second airframe member (220) having a second surface (224). An adhesive joint (226) is disposed between the first and second (224) surfaces structurally bonding the first airframe member (214) to the second airframe member (220) such that the second airframe member (224) is positioned opposite the solid insert (208).
