Description

Technical Field

[0001] The present application relates to the technical field of aircraft simulation training equipment, and in particular to a spherical screen type aircraft flight simulation training cabin. Background Art

[0002] The pilot is the core of safe aircraft operation. Whether in manned or unmanned aircraft, the pilot needs to operate the driving instruments to make the aircraft perform corresponding actions and complete the predetermined mission.

[0003] Pilots need to go through a lot of training before performing a mission alone. The training includes real-machine training and simulation training. Among them, simulation training has low cost and high safety factor, so it accounts for a large proportion of the entire training. In simulation training, a common training method is for pilots to take a simulation training cabin to perform tasks in a simulated manner in a highly simulated environment, thereby gradually improving their ability to control the aircraft. Since it is necessary to display the simulated environment, a display device is required. Commonly used display devices are flat-panel displays, which cannot simulate the spherical field of view of the human eye. In order to improve the simulation effect, the existing technology also uses a spherical projection screen. By projecting images onto the spherical projection screen, the field of view of the human eye can be simulated more realistically, such as CN116543620A and CN206893134U.

[0004] However, in existing patents, the projectors are all installed on the top of the dome screen in an upside-down manner without any supporting structure underneath, which brings considerable difficulties to the installation and maintenance of the projector. Summary of the Invention

[0009] The angle adjustment device is arranged on the inner frame and is used to rotate the projector to a certain angle in response to an instruction input by an operator, thereby increasing the available space inside the inner frame.

[0014] More specifically, the spherical screen petal includes an inner panel and an outer panel, both of which are spherical structures, and the inner panels are connected by a sandwich frame.

[0015] More specifically, the inner plate and the outer plate are both made of glass fiber reinforced plastics.

[0016] More specifically, the inner side of the inner layer plate is coated with a gain paint.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] Figure 1-8 The present invention provides a structural diagram of a spherical screen aircraft flight simulation training cabin. The present invention provides a spherical screen aircraft flight simulation training cabin, comprising:

[0033] Dome 10;

[0034] A projector mounting seat is provided on the inner top surface of the dome screen 10. The projector mounting seat includes an inner frame 400. A projector 410 is provided on the inner bottom surface of the inner frame 400. The projector 410 is used to project an image onto the inner side surface of the dome screen 10. An extension platform 430 is also provided at the bottom of the inner frame 400. A folding ladder 431 is provided at the bottom edge of the extension platform 430.

[0035] The angle adjustment device is provided on the inner frame 400 . The angle adjustment device is used to rotate the projector 410 to a certain angle in response to an instruction input by an operator, thereby increasing the available space inside the inner frame 400 .

[0036] For example, the inner side of the ball screen 10 is a spherical surface, so when the projector 410 projects an image, the pilot can feel a real simulation effect through the spherical projection area.

[0037] In an embodiment of the present application, there are multiple projectors 410, and the multiple projectors 410 are respectively arranged at different positions on the inner bottom surface of the inner frame 400, and the orientations of the respective projectors 410 are different. After the multiple projectors 410 project corresponding images to different areas of the spherical screen 10, the multiple projected images are spliced ​​to form a complete projection image.

[0038] Furthermore, after using multiple projectors 410 to simultaneously project images to different positions in the projection area, the field of view formed is 270° horizontally and 65° vertically. In the vertical field of view, the upper field of view is 35° and the lower field of view is 30°. Through large-scale projection, a huge field of view can be provided to the pilot, simulating the training environment more realistically.

[0039] The inner frame 400 can be welded from 10# channel steel. In addition to multiple projectors 410 mounted on its inner bottom surface, an extension platform 430 for operators to stand on is also required at the bottom of the outer side surface. Specifically, because the projection area has a horizontal field of view of 270 degrees, the projectors 410 are not evenly mounted along the inner bottom edge of the inner frame 400. In other words, the distance between two projectors 410 may be greater than the distance between any other two adjacent projectors 410. The extension platform 430 is positioned on the inner frame 400 corresponding to the area between the two projectors 410, allowing operators to enter and exit the inner frame 400 with ample space.

[0040] Because the projectors 410 in this application are all mounted on the inner bottom surface of the inner frame 400, with one end of the projectors 410 facing the interior of the inner frame 400 and the other end facing the exterior of the inner frame 400, the space inside the inner frame 400 is relatively small, and operators may not be able to perform maintenance work in this limited space. Therefore, this application also provides an angle adjustment device on the inner frame 400, so that when the operator needs to enter the inner frame 400, they must first rotate the normally functioning projector 410 to a certain angle, thereby increasing the available space inside the inner frame 400.

[0041] Specifically, the angle adjustment device includes an instruction receiving unit and an angle control unit. The instruction receiving unit can adopt an input unit with or without display, such as a touch screen or a key panel, which includes control buttons corresponding to each projector 410. The input unit needs to include at least two buttons, "fold" and "reset", corresponding to each projector 410. The "fold" button is used to control the corresponding projector 410 to rotate a certain angle to free up space inside the inner frame 400, and the "reset" button is used to return the projector 410 to its initial position after folding for normal projection.

[0042] The angle control unit can be a stepper motor. Each projector 410 needs to be mounted horizontally on the inner bottom surface of the inner frame 400, and each projector 410 rotates under the drive of an angle control unit to switch between the stowed and reset states. When the operator needs to enter the inner frame 400, they can determine which projector 410 to stow based on the working conditions of each projector 410. Generally speaking, when a projector malfunctions, the operator needs to change the projector 410 to its current position, while other normally functioning projectors 410 can be stowed. Therefore, the operator can select the projector 410 to be stowed on the command receiving unit and control the corresponding projector 410 to rotate a certain angle using the corresponding button to put the projector 410 into the stowed state. When the operator completes the inspection of the projector 410, the command receiving unit is used to reset each stowed projector 410.

[0043] Furthermore, the instruction receiving unit can also use a single-chip microcomputer or a microprocessor to monitor the working status of each projector 410. When a fault is detected in any projector 410, the operator can set the other projectors 410 except the faulty projector 410 to a folded or reset state through one-click operation, thereby simplifying the operator's use.

[0044] Furthermore, the extension platform 430 can adopt a steel structure, and a folding ladder 431 is set on the bottom surface of one end thereof. When the folding ladder 431 is folded, it can be separated from the contact with the ground and hung under the extension platform 430, and the space occupied at this time is very small. When the folding ladder 431 is opened, its bottom end can be in contact with the ground, and the operator can climb to the extension platform 430 through each step in turn.

[0045] In a possible embodiment, a hanging frame 310 is provided on the outer side of the inner frame 400, a hanging plate is provided on the hanging frame 310, an opening is provided on the hanging plate that matches the position of the projection port of the projector 410, and the projection port of the projector 410 extends from the opening.

[0046] For example, the hanging frame 310 can also be made of a steel structure, and the hanging plate provided thereon is used to maintain the beauty of the hanging frame 310. Since the hanging plate is located on the outer side of the hanging frame 310 and the projector 410 is located on the inner side of the hanging frame 310, an opening needs to be provided on the hanging plate so that the light projected by the projector 410 can pass through the opening and illuminate the inner side of the spherical screen 10.

[0047] In the embodiment of the present application, a hanging opening is provided on the top of the dome 10 , and a hanging plate 300 matching the hanging opening is provided on the top of the hanging frame 310 , and the hanging plate 300 is overlapped on the top surface of the hanging opening.

[0048] After the hoisting opening is provided on the dome screen 10, the top surface of the dome screen 10 becomes horizontal, and the resulting hoisting opening is circular. Accordingly, the hanging plate 300 should also be a circular or annular structure, the same shape as the hoisting opening, but slightly larger in size. The hanging plate 300 can be connected to the top surface of the hoisting opening via bolts, while the hanging frame 310 is connected to the bottom surface of the hanging plate 300.

[0049] Furthermore, a hanging rod 420 is provided at the top of the inner frame 400 and is connected to the inner side of the hanging plate 300. The hanging rod 420 can be made of a steel pipe and connects the inner frame 400 and the hanging frame 310 together, ensuring a fixed distance between them and preventing relative movement. Furthermore, the inner frame 400, hanging frame 310, and hanging plate connected to the dome 10 form a closed system. Sunshades can be installed on the hanging rod 420 and the hanging plate to prevent external light from adversely affecting the projection effect inside the dome 10.

[0050] Furthermore, due to the large size and enclosed space of the dome 10, echoes are easily generated inside when audio is played. To reduce the impact of echoes, sound-absorbing panels can be installed inside the dome 10, for example, outside the inner side projection area, on the outside of the hanging panels, or on the ground. These panels can be porous, with multiple absorption holes that confine reflected sound vibrations within a limited space and gradually absorb them, thereby absorbing most of the sound and reducing the generation of echoes.

[0051] In a possible embodiment, the spherical screen 100 is formed by splicing a plurality of spherical screen petals 100 .

[0052] For example, the number of the spherical screen petals 100 may be 8. When the 8 spherical screen petals 100 are completely spliced ​​together, a 360° surrounding structure in the horizontal direction can be formed. Therefore, the central angle of each spherical screen petal 100 in the horizontal direction is 45°.

[0053] In the embodiment of the present application, the dome flap 100 includes an inner panel 110 and an outer panel 120. Both the inner panel 110 and the outer panel 120 have spherical structures and are connected by a sandwich frame 130. The sandwich frame 130 can be a steel plate frame with the same shape as the inner panel 110 and the outer panel 120. The front and rear sides of the sandwich frame 130 are coated with a high-strength composite adhesive to bond the outer panel 120 and the inner panel 110 to the inner and outer sides of the sandwich frame 130, respectively.

[0054] Furthermore, both the inner panel 110 and the outer panel 120 are made of fiberglass reinforced plastic, and the inner side of the inner panel 110 is coated with a gain paint. Specifically, the gain paint can be D-type projection paint. By applying the gain paint, the relatively smooth inner surface of the inner panel 110 is roughened, causing light transmitted by the projector 410 to be diffusely reflected from the gain paint surface, thereby improving the display effect of the dome screen 10.

[0055] Furthermore, each spherical screen petal 100 is provided with a protruding plate 101 and an overlapping edge on both sides. The protruding plate 101 and the overlapping edge match each other. The protruding plate 101 of one spherical screen petal 100 and the overlapping edge of the other spherical screen petal 100 are overlapped together, and the overlapping portions are connected together by multiple connectors 102 to ensure a stable connection between the two adjacent spherical screen petals 100. Specifically, the connectors 102 can be countersunk hexagon socket head screws. By sequentially connecting multiple spherical screen petals 100 end to end, the spherical screen 10 is formed.

[0056] In a possible embodiment, a mounting base is further included, and the spherical screen 10 is disposed on the mounting base.

[0057] For example, the mounting base can be a steel frame or a flat plate structure. Regardless of the structure, a space for mounting the dome 10 and the simulation cabin must be reserved thereon. Specifically, expansion bolt holes can be reserved on the mounting base to facilitate mounting the dome 10 and the simulation cabin using expansion bolts.

[0058] In an embodiment of the present application, in order to facilitate the transportation of the installation base, a splicing structure can be adopted, which can be divided into multiple sub-bases 200. After the multiple sub-bases 200 are installed on site, they can be spliced ​​to form a complete installation base.

[0059] Furthermore, to prevent the simulated cockpit from transmitting vibrations to the mounting base during movement, a mounting groove 210 matching the simulated cockpit can be reserved on the mounting base. When the mounting base is installed on the ground, the mounting groove 210 will expose the ground, allowing the simulated cockpit to be fixed to the ground using expansion bolts.

[0060] In a possible embodiment, a rear room is further included. An entrance and exit are provided at the bottom of the dome 10. The rear room is connected to the outer surface of the dome 10 at a position corresponding to the entrance and exit. The interior of the rear room is used to place control equipment.

[0061] Exemplarily, the control device mainly includes a computer for controlling the projector 410 and the simulated cockpit, as well as auxiliary equipment such as tables and chairs for operators to operate the computer.

[0062] In an embodiment of the present application, the rear room is also installed on the mounting base. At the same time, in order to hide the cables, wire conduits for passing the cables can be pre-buried in the mounting base. After installing the projector 410, the simulation cockpit, the computer and other equipment, the cables can be connected between the various devices through the wire conduits, thereby improving the aesthetics of the interior of the dome screen 10.

[0063] Furthermore, the rear room body includes a room panel 500 and a door panel 510 at the opening of the rear room body. The room panel 500 includes multiple vertical panels and horizontal panels, and the vertical panels and horizontal panels are also spliced ​​to form the main body of the rear room body. At the same time, the vertical panels and horizontal panels also need to match the shape of the dome 10 to ensure that the connection between the rear room body and the dome 10 remains sealed.

[0064] After the vertical panels and the horizontal panels are spliced ​​together, the door panel 510 can be installed at the opening by pushing, pulling, or hinged connection to facilitate the opening and closing of the door panel 510 .

[0065] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0066] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
