Description
FIELD OF THE INVENTION

The present invention relates generally to an aircraft interior with panels, and more specifically to a VTOL aircraft interior with panels that include functional components thereon.


BACKGROUND OF THE INVENTION

With the rise in popularity in ride sharing, small aircraft that can accommodate a small number of passengers for relatively short (e.g., intra-city) trips are contemplated. However, current smaller aircraft, such as helicopters, light civil/VIP aircraft and other with similar sized interiors are too heavy, costly, and low volume to meet the requirements for new vertical take-off and landing (VTOL) and electric VTOL (referred to as an eVTOL) aircraft.


Some of the challenges in developing these aircraft are cost and weight. The cost of manufacture and weight of prior art helicopters and light aircraft are prohibitive in trying to get the ultimate price point down for passengers in the VTOL aircraft. Prior art aircraft typically cost in the millions of dollars each and the cost of VTOL aircraft are targeted to be in the several hundred thousand dollars range each. Therefore, limiting the number of components on an aircraft can reduce both weight and cost.


SUMMARY OF THE PREFERRED EMBODIMENTS

In accordance with a first aspect of the present invention there is provided an aircraft that includes a body that defines a cabin interior and includes an exterior surface and an interior surface, and at least a first panel member having a front and a back. The back includes a set of panel mounting components thereon and the interior surface of the body includes a set of body mounting components thereon. The set of panel mounting components are removably mounted to the set of body mounting components (to form a panel system). In a preferred embodiment, the interior surface of the body includes at least a first panel indentation defined therein and the second set of mounting components is located in the first panel indentation.


In a preferred embodiment, the aircraft includes front and back rows of seats positioned in the cabin interior. The body includes a door that is positioned adjacent the front row of seats, the set of body mounting components is located on the door, and the first panel is secured to the door. Preferably, the first panel member includes at least one functional component on the front thereof, such as at least one of an armrest, cup holder, charging port, storage pocket, handle, tie down anchor or lighting. Preferably, the body is a composite monocoque structure and the aircraft is a vertical take-off and landing aircraft. In a preferred embodiment, the first panel member is electrically communicated with the body. This can be done by electrically connecting at least one of the panel mounting components with at least one of the body mounting components. In a preferred embodiment, the aircraft with the panel system also includes a divider system.


In accordance with another aspect of the present invention there is provided a method performed on or in an aircraft that includes a body that defines a cabin interior.

The back of the first panel member includes a first set of panel mounting components thereon and the back of the second panel member includes a second set of panel mounting components thereon. The interior surface of the body includes at least first and second sets of body mounting components thereon. The first set of panel mounting components is removably mounted to the first set of body mounting components and the second set of panel mounting components is removably mounted to the second set of body mounting components. The method includes disconnecting the first set of panel mounting components from the first set of body mounting components, obtaining a third panel member having a front and a back that includes a third set of panel mounting components thereon, and removably mounting the third set of panel mounting components with the first set of body mounting components.


In a preferred embodiment, the method includes disconnecting the second set of panel mounting components from the second set of body mounting components. The second panel member can be replaced with a fourth panel member or the second set of body mounting components can be left unoccupied for the next use of the aircraft. In a preferred embodiment, the first functional component does not require power, and the second functional component requires power (e.g., when upgrading from a basic interior to a VIP interior).


In accordance with another aspect of the present invention there is provided an aircraft that includes a body that defines a cabin interior and includes an exterior surface and an interior surface with a floor, and at least a first divider member having a bottom that includes a set of divider mounting components thereon. The floor includes a set of body mounting components thereon. The set of divider mounting components are removably mounted to the set of body mounting components and the first divider is positioned such that it divides the cabin interior into a passenger section and a pilot section. In a preferred embodiment, the first divider member includes at least one functional component on a front thereof, wherein the functional component is at least one of an entertainment system, cup holder, charging port, storage pocket, handle, tie down anchor or lighting.


In a preferred embodiment, the first divider member includes a storage portion that extends into the pilot section. The storage portion defines a storage area that is accessible through a door of the aircraft.


In accordance with another aspect of the present invention there is provided a method performed on an aircraft that includes a body that defines a cabin interior and an exterior surface and an interior surface that comprises a floor, and at least a first divider member having a bottom. The bottom of the first divider member includes a first set of divider mounting components thereon. The floor includes at least a first set of body mounting components thereon. The first set of divider mounting components is removably mounted to the first set of body mounting components and the first divider is positioned such that it divides the cabin interior into a passenger section and a pilot section. The method includes disconnecting the first set of divider mounting components from the first set of body mounting components, obtaining a second divider member having a bottom that includes a second set of divider mounting components thereon and has a different shape than the first divider member, and removably mounting the second set of divider mounting components with a second set of body mounting components.


In a preferred embodiment, the first set of body mounting components includes a plurality of members, the second set of body mounting components includes a plurality of members, and some of the members of the first set of body mounting components are the same as some of the members of the second set of body mounting components. Preferably, the aircraft includes front and back rows of seats positioned in the cabin interior. A first foot space area is defined between the front row of seats and the first divider member, a second foot space area is defined between the front row of seats and the second divider member, and one of the first foot space area and second foot space area is larger than the other of the first foot space area and second foot space area. It will be appreciated that in an embodiment with both the panel system and the divider system, the body mounting components can be the same for the panels and dividers or they can be different.


The present invention provides solutions addressing new requirements for the interior of eVTOL and VTOL aircraft (referred to together herein as VTOL aircraft) that arise due to deficiencies in the current state of the art. Products within the current state of the art (e.g., helicopters, light civil/VIP aircraft with similar sized interiors) are too heavy, costly, and low volume to meet the requirements for the new types of eVTOL and VTOL aircraft. The present invention relates to a new interior product that, in a preferred embodiment, is designed specifically for use in VTOL aircraft.


The present invention includes the integration and installation of panels with the primary structure and includes a new method of installing interior panels into the primary structure of the VTOL aircraft and can include, but is not limited to, interior panels for the doors, ceiling, personal service unit (PSU) and cargo hold. The enabling design feature is the primary structure functioning as a cosmetic surface visible to passengers, with discrete inset locations for interior panels to be inserted or installed therein. It will be appreciated by those of ordinary skill in the art that the present invention can provide weight reduction and cost efficiency or reduction, when compared to the prior art and can also provide custom branding opportunities on the panels.


In a preferred embodiment, the panels can be installed and removed with a quick release system, such that they are temporary and not permanently installed. Therefore, the panels can be changed as desired.


In a preferred embodiment, the panels can also be modular and include one or more features integrated therewith or thereon. Such features can include armrests, handles, cupholders, storage, power (e.g., USB charging port), lighting, etc. Preferably, the panels also provide acoustic and vibration dampening.


In a preferred embodiment, the body of the aircraft comprises a composite monocoque structure that includes an A-side (the exterior) and a B-side (the interior). Preferably, at least a portion of the interior of the body is visible to passengers in use. The interior includes the system of plug and play panels in key areas. The panels can be different shapes for different areas, but include a common, quick-release fastening system. Preferably the panels help dampen acoustics and vibration, but also help with the styling of the interior of the vehicle. This platform approach allows the panel system manufacturer to use the same system across multiple OEMs. In other words, the present invention includes common fasteners that allow standardization for installation across the multiple OEMs that provide the benefits of platform commonality rather than providing a different attachment methodology for each different VTOL manufacturer or OEM.


In a preferred embodiment, the panels can be enhanced with features that are usable on the interior of the aircraft. The panels themselves provide a baseline product that can be enhanced through selectable options, such as an armrest, that provide functionality. For example, the “New York taxi cab” version can simply include plastic panels inside, while the VIP version of the panel can include a padded leather cover, with a cup holder and a USB charger built into it.


VTOL aircraft can also be used for cargo shipment. In some scenarios, the same aircraft can be used at times for passenger transport and at other times for cargo transport. In this situation, removal and replacement of panels quickly is vital. Therefore, the panels can include provisions or features related to cargo shipment, such as loops, hooks or other tie-downs for the connection of straps. The aircraft may also be used for emergency evacuations and the panels can be functionally equipped as necessary. As a result, the system enables users to remove and replace panels quickly to completely cosmetically change out a passenger vehicle for a cargo vehicle in a minimum amount of time.


The present invention is directed to a system that allows one more aircraft dividers or bulkheads to be configured for different uses and interior arrangements that can provide for storage, additional front row leg room, cabin densification, asymmetrical cabin configurations (or symmetrical cabin configurations), etc.


This platform approach allows the divider member system manufacturer to use the same system across multiple OEMs. In other words, the present invention includes a common attachment system that allow standardization for installation across the multiple OEMs that provide the benefits of platform commonality rather than providing a different attachment methodology for each different VTOL manufacturer or OEM.


The present invention allows a divider member to be easily removed and replaced with a divider member having a different configuration. This allows fast reconfiguration of the aircraft interior. Furthermore, the divider members can include different built in functionality or components depending on the intended use of the aircraft. For example, a simple divider member with no functional components thereon can be used for a cargo aircraft, while a divider member that includes functional components such as storage pockets, cup holders, charging ports, televisions, etc. and other components related to passenger use can be included. For example, the basic divider member may just be a composite panel, and the VIP version may include a leather covered composite panel with embedded lighting and a cup holder.


It will be appreciated that both the removable panel system and the removable divider system can be used alone or together in a single aircraft.


The present invention can be used in conjunction with other concepts related to VTOL aircraft, such as the inventions and concepts taught in U.S. application Ser. No. 16/566,652, the entirety of which is incorporated by reference herein. The common quick-release system and concept can be similar to the systems described in U.S. Pat. Nos. 9,527,591 and 9,562,549, the entireties of which are incorporated herein by reference.

Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-5 show a VTOL aircraft 10 that includes a changeable panel system 12 therein. FIG. 1 shows a plan view of the aircraft 10 including a body 14 that defines a cabin interior 16 and a plurality of panel members 18 secured to an interior surface 14a of the body 14. The panel members 18 each include a front 18a and a back 18b. The back 18b includes a set of first or panel mounting components 20 thereon that is compatible with a set of second or body mounting components 22 on the interior surface 14a of the body 14. The set of panel mounting components 20 are removably mounted to the set of body mounting components 22. Generally, this means that the set of panel mounting components 20 can be easily and quickly removed from or disconnected from the set of body mounting components 22, as discussed above. For example, as shown in FIGS. 3-4, the panel mounting components 20 can be a post, protrusion or other male component that snap fits, press fits or otherwise is received and retained into a female receptacle (the body mounting component) in the wall of body 14. FIGS. 3-4 show a ridge 21 on the male component that is received in an annular groove in the female component. However, this is only exemplary and any complementary sets of first and second mounting components that allow quick release of the panel members from the body is within the scope of the present invention. The male and female components can be reversed such that the male components are on the wall and the female components are on the panel member.


As shown in FIGS. 2-4, in a preferred embodiment, the body 14 includes a plurality of panel indentations 24 that receive at least a portion of the panel members 18. The body mounting components 22 are positioned in the panel indentation 24. This allows the panel members 18 to be inset into the wall or body of the aircraft. The panel members 18 can be shaped so that a portion of the panel member is received in the panel indentation 24 and inset therein and an outer edge and/or surface can be flush with the inner surface 14a of the body 14. This can provide a relatively seamless look for the walls. FIG. 2 shows a first panel member 18 received in the forwardmost panel indentation 24 and two further panel indentations 24 without a panel member received therein. FIG. 2 also shows a long panel member connected to the ceiling of the body 14. It will be appreciated that the panel members 18 can be different sizes and can be connected to any interior surface within the cabin interior. Furthermore, the panel members 18 can be received in panel indentations or can be connected to an area of the body without a panel indentation.


As shown in FIG. 5, in a preferred embodiment, the panel members 18 are modular and can include one or more functional components on a front thereof that can be usable by passengers or for other purposes. For example, a panel member can include an armrest 26, cup holder(s) 28, charging port(s) 30, storage pocket(s) 32, handle(s) 34, tie down anchor(s) 36 (loops, hooks or the like for connecting straps or ropes to tie down cargo), lighting, branding, an opening for the door latch mechanism, etc. In an embodiment of the invention, the male and female mounting components can include electrical connection capability (at least one of the set can include electrical connection capability). Therefore, if the functional component needs power (e.g., lighting, charging port), power or electricity can be provided.


As shown in FIG. 1, in a preferred embodiment, the aircraft 10 includes front and back rows of seats 38 positioned in the cabin interior. The seats 38 include a door or doors 40 adjacent thereto for ingress and egress. The doors can include panel members 24 connected thereto.



FIGS. 1 and 6-10 show a VTOL aircraft 10 that includes a changeable divider system 50 therein. This system allows different dividers or bulkheads to be usable with different OEM bodies or allows different dividers to be changed or swapped out for different situations or arrangements within the same body.



FIGS. 6, 7 and 10 show different shaped from dividers 52 positioned between the pilot and the passenger cabin. Similar to the panel system discussed above, the divider system 50 includes a first or divider set of mounting components 54 that are positioned on or associated with the divider 52 and a second or body set of mounting components 56 that are positioned on or associated with the wall, floor or ceiling of the body 14.



FIG. 8 shows a plurality of male components that represent the set of divider mounting components 54 extending from the divider 52 and a plurality of female components on the floor or body 14 that represent the set of body mounting components 56. All discussion above related to sets of mounting components on the panel system is relevant to the divider system. FIG. 8 shows to different shaped dividers 52 and sets of body mounting components 56 related thereto. Therefore, a first set of divider mounting components 56 can be usable with one divider and a second set of divider mounting components 56 can be usable with a different divider.



FIG. 9 shows dividers similar to those in FIG. 8, but with tracks or channels on the floor that are the set of body mounting components 56 and feet on the dividers 52 that are the set of divider mounting components 54. These tracks or channels can be the same that are used for mounting the seats or can be separate.


As discussed above, an advantage of the different shaped dividers is the ability to provide space in different areas. For example, as shown in FIG. 6 storage space 60 can be provided on both sides of the pilot seat. As shown in FIG. 7, foot space 62 can be provided for the passengers in the front row. As shown in FIG. 10, both storage space 60 and foot space 62 can be provided by the divider shown therein. The storage space 60 can simply be space within the aircraft interior, as represented by the phantom lines in FIG. 6 or can be defined by structure, as shown in FIG. 10. FIG. 9 shows a storage portion 64 that is a part of and/or connected to the divider 52. The storage portion 64 can include a first set of mounting components 54 thereon that are secured when the divider 52 is installed.


In a preferred embodiment, the dividers 52 include functional components thereon, similar to the panel system discussed above (any of the functional components discussed above can be included thereon). For example, FIG. 8 shows tie down anchors 36 and entertainment systems 66 (e.g., TVs) thereon.
