Virtual window for aircraft

Abstract

To create an environment in which the passenger has the same emotion, feel and visual experience that a pilot has with regard to freedom of flight and proximity to the exterior of the aircraft and where passengers have the impression that they are looking out of an actual panoramic window, a “virtual window” includes internal and the external aspects of a real window. The internal part can comprise a folded or flexible high resolution color display that conforms to the internal profile of the aircraft fuselage as if it were an actual window. The external part comprises a paint scheme that is indistinguishable from an actual window and which is placed on the outside of the aircraft fuselage in registry with the conformal display in the aircraft's interior.

DETAILED DESCRIPTION

(7) FIGS. 1A & 1B show an example prior art aircraft illustrating a jet windshield design that gives the pilot a panoramic view of the horizon. As can be seen, the window panels are formed in a curved wraparound design to provide a panoramic view with good visibility in all directions. An example non-limiting implementation of a virtual window display provided herein creates the impression and feel of an additional such a panoramic window above the cockpit window for example without requiring any expensive modifications or special aircraft fuselage designs. Such an example non-limiting implementation provides an environment in which the passenger has the same perspective, feel and emotion that a pilot has with regard to freedom of flight and proximity to the exterior of the aircraft.

(8) The creation of such an environment is accomplished through a virtual window according to the example non-limiting embodiment. To comprise the internal and the external aspects of a real window, the virtual window according to the example non-limiting embodiment has two main parts: an internal part and an external part.

(9) As shown in FIGS. 2, 3 and 4, the internal part of the virtual window comprises an internal screen (e.g., an electronic display) positioned on the aircraft ceiling in the forward region of the cabin adjacently to the windshield. The external part of the virtual window comprises a painting scheme on the external surface of the aircraft fuselage (see FIG. 4). This virtual window provides a sense of permeability between the outside and inside of the aircraft through the reproduction of images externally captured and internally transmitted in real time.

(10) The virtual window emulates a large actual transparent window on the aircraft ceiling. As this is a virtual window, there is no need to cut holes or otherwise modify the airplane structure or fuselage. The internal part of the virtual window may comprise a flexible conformal display capable of being pressed into conformance over the interior ceiling finishing or even integrated on the interior ceiling finishing (e.g., seamless transition or flush finishing). In one example non-limiting embodiment, such flexible display is positioned adjacent to the cockpit windshield region and shows the external viewing captured by a camera installed outside of the aircraft, as depicted in FIG. 3.

(11) To provide the external aspect of a window, the external part of the virtual window comprises a paint scheme on the external surface of the aircraft, matching in registration with the area of the internal part of the virtual window. This paint scheme emulates a window with a solar film protection applied, as can be seen in FIG. 4. When the passengers are outside the aircraft, they may have the impression of the presence of the actual additional window through this paint scheme.

(12) The example non-limiting embodiment gives to the passenger an impression that there really is an additional panorama window at that location in the aircraft. Once the passenger reaches the interior of the aircraft he will see the display which matches with the external paint scheme and thus continues to emulate the presence of a window at that location.

(13) The virtual window according to the example non-limiting embodiment gives to passengers the same feeling (and the same sense) the pilots have with respect to the freedom of flight and to the proximity to the exterior of the aircraft. By the presented virtual window, the passengers may have a view of the horizon as the pilots usually have by looking through a real panoramic cockpit window.

(14) In one example non-limiting implementation, the shape of the area of the virtual window adopts flowing lines that follow the cylindrical shape of the fuselage, seeking to maintain a visual language that combines with the external, internal and general language of an aircraft.

(15) As can be seen in FIG. 2, the internal part of virtual window may comprise a flexible display which is positioned on the aircraft ceiling in the forward region of the cabin adjacent to the windshield region. The virtual window extends upwardly from the windshield region. Alternatively, such flexible display, which composes the internal part of the virtual window, may extend upwardly from a region which is close (next) to the windshield region.

(16) FIG. 2 presents a side view of the virtual window (1) which is represented by the points A4, A5, B1, B2, B3 and B4. In this figure, the reference number 2 references the cockpit region.

(17) As shown in FIG. 3, the area of the internal part of the virtual window (3) is bounded by a set of curves defined by the points C1, C2, C3, C4, C5 and C6.

(18) As depicted in FIG. 3, the borders of the internal part of the virtual window comprise flowing lines.

(19) Relative to the passengers' view, as shown in FIG. 3, the left lateral border of the internal part of the virtual window (3) in one example non-limiting implementation comprises, from the point C1 to C3, a serpentine border formed by flowing lines. Relative to the center of the internal part of virtual window, this left lateral border, from the point C1 to C3, is preferably formed by a concavity followed by convexity which is followed by a concavity. As the virtual window is symmetric, the right lateral border of the internal part of the virtual window (3) is a mirrored line of the left border.

(20) According to FIG. 3, the angle between the lines formed by points C2C1 and C1C6 is obtuse. By symmetry, the angle formed by the lines C5C6 and C6C1 is obtuse. The line 4 represents the line of symmetry.

(21) As can be seen in FIG. 4, the external part of the virtual window may comprise a paint scheme that represents the same geometry as the internal part of the virtual window. This paint scheme gives to the virtual window the visual effect that emulates the extending of the windshield until a given intermediate section of the upper region of the aircraft fuselage.

(22) Alternatively, the external part of the virtual window may comprise a paint scheme that represents the similar geometry of the internal part of the virtual window.

(23) FIG. 4 shows the external part of the virtual window (3). In this figure, it is observed that the windshield of the aircraft is composed of units represented by the numbers 5, 6, 7 and 8. The lower border of the external part of virtual window (3) is parallel to the line formed by the windshield parts (5, 6, 7 and 8).

(24) The region of the cabin near the virtual window may contain a sofa, as illustrated in FIG. 2, or other type of furniture or structure such as seats or a bed. Imagine meditating, drifting off to sleep, etc. with a panoramic view of the sky and clouds spread out before you. The night sky would be magnificent in such a panoramic view, and the day sky with clouds, birds, other aircraft etc. would provide endless fascination.

(25) As shown in FIG. 5, the data processing system shown, through software, may provide the presentation of the exterior images in the flexible display according to the internal structural configuration in the forward region of the cabin. In particular, a front-facing camera 102 positioned on the outside of the aircraft may capture moving color images in real time of the sky and horizon in front of the airplane. An image processing module 104 may process the captured images in a conventional fashion under control of a control system 110. An image transformation module 106 may, under software control, transform or warp the image appropriately to match the perspective of viewers within the airplane's interior. For example, if in the region near to the flexible display there is a sofa, as illustrated in FIG. 2, the data processing system image transformation module 106 may provide the presentation of the images in certain way (at a certain angle of view, for example). On the other hand, if near the flexible display there are seats instead of sofa, the data processing system image transformation module 106 may provide the presentation of images in another way (at other angle of view, for example). This different way of image presentation provides the best visualization for the passengers so that they may enjoy the images from the horizon during the flight. The resulting transformed image may be displayed on a high resolution FOLED or other suitable electronic display device 108 within the interior of the aircraft. Preferably, the control module 110 is designed to display appropriate images on display 108 whenever the airplane is powered on but not yet moving to avoid destroying the illusion of a window.

(26) Another example non-limiting embodiment may be implemented by installing in the outside part of the aircraft, instead of a paint scheme, another flexible display (a FOLED display, for example) which may show the internal aircraft viewing captured by a camera installed inside of the airplane. This provides the illusion and functionality of a two-way transparent window. A polycarbonate layer may be applied over this external flexible display in order to avoid aerodynamic erosion. Such external flexible display, alternatively, may also show advertising messages or even any other kind of visual communication such as videos, movies, pictures or illustrations.

(27) The internal flexible display also, alternatively, may show advertising messages or even any other kind of visual communication such as videos, movies, pictures or illustrations.

(28) While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
