    [0001] Modalities of the present invention generally refer to the dynamic fluid design. More particularly, embodiments of the present invention relate to the design of variable sweep dynamic fluid bodies. BACKGROUND
    [0002] The size limitations of commercial aircraft can be caused by the size restrictions of the circulation path of the airport gate. Increased wing spans can be used to increase aircraft performance such as lift-to-drag related efficiency performance. Increasing aircraft wing span to increase aircraft design may conflict with airport gate and passageway size restrictions. For example, airport gates and passageways built for one generation of aircraft may be too small for future generations of aircraft built with longer wing spans. Airport restrictions can prevent aircraft with larger wingspans from flying more efficiently because they are used at airports with such airport restrictions. SUMMARY
    [0003] A swivel joint and methods for rotatably coupling an oscillating tip assembly to a dynamic fluid body are presented. A turntable that can be coupled to the swing tip assembly comprises a slip ring consisting of an open center, an upper slide surface, an inner slide surface and a lower slide surface. A top gasket plate is slip-coupled to the top slide surface and the inner slide surface and can be coupled to the dynamic fluid body. A lower gasket plate is slide coupled to the lower slide surface and the inner slide surface, and is coupled to the upper gasket plate through the open center. The lower gasket plate can also be coupled to the dynamic fluid body.
    [0004] The swivel joint allows a wing tip to rotate backwards to facilitate a reduced wing span, for example, during movement and parking maneuvers, and other applications. The swivel joint comprises an inner “donut” ring attached to the wing tip, held in place by lower and upper plates attached to the wing box frame. In addition, the wing tip can be rotated forward for high speed aerodynamic benefit, rear rotation for low speed aerodynamic benefit, and increased rear rotation for driving and parking maneuvers.
    [0005] In this way, embodiments of the invention provide an ability to change an aircraft wing span. Therefore, the aircraft can be more efficient in flight with a larger wing span that can still be accommodated within existing airport restrictions.
    [0006] In one embodiment, a swivel joint for rotatably coupling an oscillating tip assembly to a dynamic fluid body, comprises a swivel plate, an upper joint plate and a lower joint plate. The turntable attaches to a wobble tip assembly and comprises a slip ring having an open center, a sliding top surface, a sliding inner surface, and a sliding bottom surface. The upper joint plate is slip-coupled to the upper sliding surface and the sliding inner surface, and is configured to mate with a dynamic fluid body. The lower gasket plate is slip-coupled to the lower sliding surface and the inner sliding surface, and is configured to mate with the upper gasket plate through the open center, and is configured to mate with the body of dynamic fluid.
    [0007] In another embodiment, a method for providing rotation of a swinging tip assembly coupled to a body of dynamic fluid provides a turntable configured to mate with the swinging tip assembly. The turntable comprises a slip ring comprising an open center, an upper slide surface, an inner slide surface and a lower slide surface. The method further slidingly couples an upper joint plate to the upper slide surface and the inner slide surface, the upper joint plate is operated to engage a body of dynamic fluid. The method further slidingly couples a lower joint plate to the lower slide surface and the inner slide surface, the lower joint plate is operated to engage a body of dynamic fluid. The method further couples the lower joint plate to the upper joint plate through the open center.
    [0008] In another embodiment, a method for operating a swivel joint for an oscillating tip assembly coupled to a dynamic fluid body slides a sliding top surface of a slide ring of a turntable onto a top sliding coupling to a platen upper joint coupled to the dynamic fluid body. The method further slides a sliding lower surface of the slip ring in a lower sliding coupling to a lower joint plate coupled to the dynamic fluid body. In addition, the method slides an inner sliding surface of the slip ring into the upper slip coupling, the lower gasket plate is coupled to the upper gasket plate through an open center of the slip ring. The method then sets up a position of the swinging tip mounting on an aircraft of the fluid dynamic body by rotating the turntable with respect to the upper joint plate and the lower joint plate; the turntable is attached to the swing tip mount.

Thus, the wing 302 and the body of fluid dynamics 302 can be used interchangeably in this document. Similarly, the swivel wing tip 306 and the swivel tip assembly 306 can be used interchangeably in this document. Figure 4 may have functions, material, and structures that are similar to the modalities shown in Figure 3. Thus, common features, functions, and elements may not be redundantly described here.
    [00055] Increasing the span using the 304 Swivel Joint ensures constant structural integrity whether the 306 Swivel Wing Tip is in a High Speed Extended Configuration 404 Dismissed in Flight or the 406 Swivel Retracted configuration during gate or circulation parking maneuvers. The rotating wing tip 306 can also rotate in flight during different flight modes such as low speed flight.
    [00056] Figure 5 is an illustration of an exemplary perspective view of a swing tip mounting system 500 (system 500) showing the rotary wing tip 306 in the 404 high-speed extended configuration, and a rearward-projected configuration, low speed swivel 502, and in a rotated stowed position 406 during gate or circulation parking maneuvers in accordance with an embodiment of the invention.
    [00057] Swivel wing tip 306 can be installed by swivel joint 304 of aerodynamic body 302 through a plurality of positions. Positions can start by positioning the 306 rotary wing tip forward in the 404 high speed extended configuration and moving through the intermediate positions to the installed position. The installed position may comprise positioning the swivel wing tip 306, for example, but not limited to, in the backward designed configuration, low-speed swivel 502, the rotated stowed position 406 during circulation and gate parking maneuvers, or other installed position .

    [00062] When the tip of the rotating wing 306 is not rotated, the movable panel 318 is in up 710.
    [00063] Before the tip of the rotary wing 306 is rotated, the movable panel 318 folds into a folded position 712, and falls below the trailing edge 608 in response to a movable actuator of the panel 702. The movable actuator of the panel 702 may comprise, for example, but not limitation, a linear hydraulic drive, a ball screw drive, an electric drive, or other drive mechanism.
    [00064] In a rotated position such as the backward design configuration, low-speed swivel 502 and the rotated stowed position 406, a locking mechanism 704 can be coupled to the cylindrical mating surfaces 316 of the swivel joint 304 to secure the swivel wing tip 306. In this way, the locking mechanism 704 locks a position of the tip of the rotary wing 306 by locking a rotation position of a rotation plate 940 with respect to an upper joint plate 920 and a lower joint plate 960 (Figure 9). Locking mechanism 704 (locking actuator 704) may comprise, for example, but not limited to, a linear hydraulic actuator, a ball screw actuator, an electric actuator, or other drive mechanism.

The 700A system may have functions, material, and structures that are similar to the 700 system. Thus, common features, functions, and elements may not be redundantly described here.
    [00067] When the tip of the rotary wing 306 is not rotated as in the 404 high speed extended configuration, the movable panel 318 is in a closed position 720.
    [00068] Before the tip of rotary wing 306 is rotated, movable panel 318 in sliding configuration 726 slides on a roller 716 supported by tacks 718 in a slid position 722 in a rearward projected, low-speed rotary configuration 502, or on a slid position 724 in a rotated stowed position 406 during gate or circulation parking maneuvers.

The swivel joint 304 comprises compatible cylindrical surfaces 920, 940 and 960 (316 in Figure). 3), and is coupled to the swivel wing tip 306. The swivel joint 304 rotates the swivel wing tip 306 in plane 504 (Figure 5) of the wing 302.
    [00071] Compatible cylindrical surfaces 920, 940 and 960 comprise an upper fixed joint plate 920, a middle inner swivel joint plate 940, and a lower fixed joint plate 960. The middle inner swivel joint plate 940 is coupled to the rotary wing tip 306 and is configured to rotate rotary wing tip 306 in plane 504 of wing 302 in response to a drive command. The upper fixed joint plate 920 attaches to the middle inner swivel joint plate 940 and attaches to the wing 302 and holds the middle inner swivel joint plate 940 in place. The lower fixed joint plate 960 also attaches to the middle inner swivel joint plate 940 and attaches to the wing 302 and holds the middle inner swivel joint plate 940 in place.
    [00072] Figure 10 is an illustration of an exemplary perspective view of compatible cylindrical surfaces 920/940/960 of the swivel joint 304 of the wobble tip assembly 306 according to an embodiment of the invention. Compatible cylindrical surfaces 920/940/960 comprise upper fixed gasket plate 920 (upper gasket plate 920), middle inner swivel gasket plate 940 (rotating plate 940), and lower fixed gasket plate 960 (plate of the lower gasket 960).

In addition, the wing tip can be swiveled forward for high speed aerodynamic benefit, part swiveled backward for low speed aerodynamic benefit, and swiveled backward for circulation and gate parking. Thus, the modalities provide an ability to change the aircraft wingspan allowing the aircraft to be efficient in the flight with even greater wingspans being accommodated within the existing airport restrictions.
