Description

Technical Field

[0001] The present invention relates to the technical field of aircraft engine exhibitions, and in particular to an interactive exhibition structure and method for aircraft engines. Background Art

[0002] As the heart of an aircraft, an aircraft engine is a high-precision and complex thermal machine. In order to let more people understand aircraft engines, a part of aircraft engines will be displayed in the aviation museum so that visitors can understand the development history of aircraft engines, the differences in design ideas of different aircraft engines, and the main characteristics of aircraft engines in different eras. However, the current exhibition of aircraft engines is mostly in the form of static display. For visitors who do not understand the overall structure of aircraft engines and visitors who want to have a deep understanding of the structural characteristics of aircraft engines in different eras, this way of visiting is not so intuitive. Therefore, it is necessary to design a display method that can conveniently display the structure of each part of the aircraft engine and take into account the display of the coordinated operation logic of each part of the aircraft engine, so that visitors can have a more intuitive understanding of the composition and working principle of aircraft engines. Summary of the invention

[0003] In order to solve the problem that the existing aircraft engines are based on static display and it is difficult for visitors to intuitively understand their structures and working principles, the present invention proposes an interactive display structure and method for aircraft engines, in order to solve the above problem.

[0004] In a first aspect, a display structure for an aircraft engine is provided, comprising a support frame, an aircraft engine, a lighting device, a data acquisition device, an audio playback device, and a controller;

[0011] A servo motor connected to the controller for communication is arranged in the fairing on the fan, the transmission shaft end of the servo motor is connected to the keyway of the spline shaft, and the spline end of the spline shaft is fixedly connected to the aircraft engine shaft.

[0012] Furthermore, the fan, compressor, combustion chamber, turbine and tail nozzle components in the aircraft engine are all sprayed with diffuse reflection paint.

[0013] Furthermore, the lighting device is a projection lamp or a lamp with a spotlight; the lighting device projects light onto the fan, compressor, combustion chamber, turbine and tail nozzle respectively.

[0014] Furthermore, the data acquisition device includes an infrared sensor, and the infrared sensor is arranged at the entrance and exit of the exhibition hall or booth.

[0015] Furthermore, it also includes a display device; the display device is used to display the structure of the aircraft engine through video.

[0016] In a second aspect, a method for displaying an aircraft engine is provided, comprising the following steps:

[0017] S1. Determine whether someone has entered the exhibition hall or booth by using data collected by a data acquisition device at the entrance of the exhibition hall or booth; if so, proceed to S2, otherwise repeat S1;

[0018] S2. The controller sends a control signal to the lighting device, audio player, servo motor and display device to start audio and video and physical display;

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 This is a schematic cross-sectional view of the present invention after the outer shell of the aircraft engine is approximated as a regular cylinder;

[0032] Figure 2 The present invention is a flow chart of a method for displaying an aircraft engine. DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the specific embodiments of the accompanying drawings.

[0034] With the development of aerospace industry, more and more people are paying attention to aerospace related work. As the heart of aerospace, the aircraft engine is a high-precision and complex thermal machine. It is difficult for visitors to understand its working principle only through static display; therefore, the present invention hopes to provide a dynamic display method to realize the dynamic display of aircraft engines.

[0035] In a first aspect, an interactive display structure for an aircraft engine is provided, comprising a support frame, an aircraft engine, lighting equipment, a data acquisition device, an audio playback device, and a controller, etc.; the lighting equipment, the data acquisition device, and the audio playback device are all electrically connected to the controller.

[0036] The aircraft engine to be displayed is a complete aircraft engine, but in order to display its internal structure, its external shell needs to be cut. Figure 1 As shown, it is a schematic cross-sectional diagram of the outer shell of the aircraft engine after it is approximated as a regular cylinder and displayed from its end direction, with only one-quarter and one-half cross-sections taken; it can be known that the shell can be cross-sectioned along its axial direction at one-quarter to one-half of the circumference to obtain a display window; the fan, compressor, combustion chamber and turbine in the aircraft engine are all exposed through the display window for display.

[0037] A preferred implementation is to cut the shell into half of its circumference along its axial direction, that is, only half of the shell is retained.

[0038] Although the shell is cut, the internal structure of the aircraft engine is not destroyed, especially the transmission structure based on the aircraft engine shaft. In order to enable the transmission structure of the aircraft engine to rotate, a servo motor connected to the controller is arranged in the fairing on the fan in this embodiment, and the transmission shaft end of the servo motor is connected to the keyway of the spline shaft, and the spline end of the spline shaft is fixedly connected to the aircraft engine shaft. That is, by controlling the operation of the servo motor, the blades on the fan, compressor and turbine of the aircraft engine can be rotated, so that visitors can understand the working principle of the aircraft engine more intuitively. That is, driven by the servo motor, the compressor and turbine of the aircraft engine can be driven to rotate, simulating the transmission process and transmission effect of each internal part of the aircraft engine in working state, so that visitors can understand the overall transmission process of the aircraft engine more intuitively.

[0039] Since the servo motor drives the relevant parts of the aircraft engine to operate, in order to prevent visitors from touching the rotating blades in the aircraft engine and getting injured during the visit, a transparent acrylic sheet is needed to make a protective cover. The ideal appearance of the protective cover is to make a one-to-one replica of the cut-off aircraft engine shell, and then combine the replica acrylic protective cover with the remaining shell part of the aircraft engine, so that visitors can observe the internal structure and working method of the aircraft engine, and avoid injuries to visitors who accidentally touch the blades of the aircraft engine driven by the servo motor.

[0040] Since this embodiment requires the use of lighting effects to assist in the display, when an acrylic protective cover is provided, it is inevitable that the reflection of the light by the protective cover will cause a poor visitor experience. Therefore, the best solution in this embodiment is not to use an acrylic protective cover. In order to prevent visitors from accidentally touching the running blades and getting injured, the present invention is also provided with a set of sensors to collect whether there are visitors who are too close to the aircraft engine on the display support frame.

[0041] That is to say, a sensor such as an infrared sensor, a laser radar or a millimeter wave radar is set at a preset distance near the aircraft engine to detect whether a visitor's body, arm or foot enters the preset distance near the aircraft engine. Generally, we set the preset distance to 10cm, which does not affect visitors' viewing at a closer distance and can also prevent accidental injuries to visitors.

[0042] When infrared sensors are used, multiple sets of sensors are required, which are set at the periphery of the aircraft engine with a small spacing. This method requires more sensor groups and is more troublesome. In this embodiment, the best method is to use millimeter wave radar, which has been widely used in the field of intelligent driving of automobiles as the eyes of vehicles; it has the advantages of accurate detection, etc. When using millimeter wave radar, only one millimeter wave radar is needed, which is set just above the aircraft engine to detect the visitor's body parts approaching the aircraft engine.

[0043] When it is detected that a visitor's body part approaches and enters the preset safety distance of the aircraft engine, the controller controls the servo motor to stop rotating. Since the servo motor has good controllability and its transmission shaft end is connected to the keyway of the spline shaft, and the spline end of the spline shaft is fixedly connected to the aircraft engine shaft; when the servo motor stops rotating, the aircraft engine shaft will also stop rotating.

[0044] Since lighting effects are used to assist in the display, and the aircraft engine's fan, compressor, combustion chamber, turbine, tail nozzle and other structural parts are all made of metal, which is relatively smooth and easy to produce reflections, thus affecting the lighting display effect. Therefore, it is necessary to spray diffuse reflective paint on the fan, compressor, combustion chamber, turbine and tail nozzle components in the aircraft engine.

[0045] The processed aircraft engine is placed on the support frame, and the aircraft engine and the support frame can be welded or fixed by bolts. The fixing methods are easy to implement by those skilled in the art, so no further limitation is made on the fixing methods. In order to facilitate the movement of the aircraft engine and to install it in the corresponding exhibition stand or exhibition hall, rollers can be installed on the support legs of the support frame.

[0046] The lighting device in this embodiment is configured to provide a light source for the aircraft engine; specifically, the lighting device can be a lamp with a focusing tube, which can change the shape of the light beam to project a light beam that matches the relevant parts of the aircraft engine. The most preferred embodiment is that the lighting device is a projection lamp; the projected light is controlled by a controller, and while the light is given a color, corresponding light and shadow effects can be added. For example: the lighting device projects a light blue light effect with airflow effects at the fan, compressor and the periphery of the combustion chamber; the lighting device projects an orange light effect with a jet flame in the combustion chamber; the lighting device projects an orange light effect with an airflow effect at the turbine and tail nozzle. It can be seen that the use of a projection lamp can enable visitors to understand the working principle of the aircraft engine more intuitively, that is, the display effect is more vivid and interesting; it is conducive to the popularization of relevant knowledge.

[0047] In addition, the present embodiment also includes a display device; the display device is used to display the structure of the aircraft engine through a video. That is, during the display, relevant audio and video will be played to introduce the various components of the aircraft engine; when the audio and video introduce a certain component, the projection lamp will also project the corresponding lighting effect on the corresponding component of the aircraft engine; for example, when the audio and video introduce the combustion chamber, the projection lamp will project a light blue lighting effect with airflow effects on the periphery of the combustion chamber; in the combustion chamber (i.e., inside the combustion chamber, that is, the combustion chamber will also be cut open to show its internal structure), an orange lighting effect with a jet flame will be projected.

[0048] When the audio and video introduce the entire aircraft engine one by one, the projection lamp here can simultaneously project the corresponding lighting effects to the corresponding parts. It should be noted that the specific lighting effect projection can be adjusted according to the situation, and its principle is similar to that of the projector, which will not be repeated here.

[0049] The installation of lighting equipment is generally set on a lamp rack on the ceiling of the exhibition hall. The installation of the equipment can be optimized according to the actual situation on site and is not limited to any one installation method.

[0050] In order to realize intelligent display, energy can be saved when there are no visitors, and labor costs will not be increased. The data collection equipment in the present invention is configured to collect visitor information; in addition to the aforementioned data on whether visitors are too close to the rotating blades of the aircraft engine, a sensor is also provided to collect information about visitors entering and leaving the booth or exhibition hall. The same sensor can also be an infrared sensor, a laser radar or a millimeter-wave radar, and the millimeter-wave radar method is also preferred; its specific settings and working methods are not described here in detail, and its method of collecting information about visitors entering and leaving the booth or exhibition hall is its conventional usage method or scenario.

[0051] It can be seen that the visitor's visit can be automatically identified and the display can be turned on through the relevant sensors. When the visitor leaves, the lighting equipment used for the display can be turned off according to the preset timer, thereby achieving the purpose of energy saving.

[0052] It should be noted that if infrared sensors are used, they need to be installed at the entrance and exit of the exhibition hall or booth.

[0053] In addition, the installation locations of the audio playback device and the display device can be determined according to the actual conditions of the exhibition hall or booth, which will not be elaborated here.

[0054] It should be noted that the controller in this embodiment can be a PC, and the light effect projection of the lighting device can be controlled by the PC; in addition, a single-chip microcomputer connected to the servo motor is also provided at the servo motor, and the single-chip microcomputer is used to control the operation of the servo motor and supply power to it. The single-chip microcomputer communicates with the PC through wireless communication methods such as Bluetooth or WIFI.

[0055] In a second aspect, based on the above-mentioned display structure, a display method for an aircraft engine is also provided, such as Figure 2 As shown, the following steps are included:

[0056] S1. Determine whether someone has entered the exhibition hall or booth based on the data collected by the data acquisition device installed at the entrance of the exhibition hall or booth; if so, proceed to S2, otherwise, repeat S1.

[0057] The best way is to set up the millimeter-wave radar equipment directly above the aircraft engine. When it detects someone in the exhibition hall or booth, it means that someone has entered the exhibition hall or booth; if there is no one, it means that no one has entered the exhibition hall or booth.

[0058] S2. The controller sends a control signal to the lighting device, the audio player, the servo motor and the display device to start the audio, video and physical display; wherein the audio, video and physical display are specifically:

[0059] When the audio and video are playing, the servo motor drives the blades in the fan, compressor and turbine to rotate; based on the current audio and video content, the lighting equipment projects the preset lighting effects on the corresponding parts of the aircraft engine. For example: the lighting equipment projects a light blue lighting effect with airflow effects around the fan, compressor and combustion chamber; the lighting equipment projects an orange lighting effect with a jet flame in the combustion chamber; the lighting equipment projects an orange lighting effect with airflow effects at the turbine and tail nozzle.

[0060] For a better visitor experience, the speed of the servo motor is adjustable, and its speed matches the flow rate of the airflow effects in the light effects projected by the lighting equipment.

[0061] S3. After the exhibition is started, the data collected by the data collection device installed at the exit of the exhibition hall or booth is continuously used to determine whether all people have left the exhibition hall or booth; if so, enter S4, otherwise repeat S3.

[0062] S4. The controller starts the timer. When the timer reaches the preset time, the controller sends a control signal to the lighting device, audio playback device, servo motor and display device to turn off the audio and video and physical display.

[0063] In addition, in the optimal display method, since no acrylic protective cover is provided, in the scheme of detecting whether a visitor has entered the exhibition hall or booth by setting up a millimeter-wave radar, when the millimeter-wave radar detects that there is a visitor in the exhibition hall or booth, it is also necessary to detect whether the visitor's body, arm or foot enters within a preset distance near the aircraft engine. If it is detected that the visitor's body, arm or foot enters within a preset distance (such as 10cm) near the aircraft engine, the controller immediately sends a signal to the microcontroller to stop the servo motor, and then the microcontroller controls the servo motor to stop working.

[0064] In summary, it can be seen that the scheme of the present invention can realize the dynamic display of the aircraft engine, and combined with the projection of lighting effects, the working principle of the aircraft engine can be displayed vividly and intuitively.
