[0041] In order to enable those skilled in the art to better understand the present solution, the technical solution in the embodiments of the present solution will be clearly described below in conjunction with the drawings in the embodiments of the present solution. Obviously, the described embodiments are embodiments of a part of the present solution, not all embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.
[0042] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.
[0043] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:
[0044] Figure 1 A schematic diagram of the structure of a turbojet engine test platform provided by an embodiment of the present disclosure. Figure 1 The turbojet engine test platform 100 comprises:
[0045] U-shaped bracket 101 , thrust module 102 , control module 103 , sensor acquisition module 104 , power module 105 .
[0046] The U-shaped bracket 101 is used to place the external engine.
[0047] The U-shaped bracket 101 includes: a slide rail, a base plate, a pulley, a vertical baffle and a fixing bolt. The slide rail is arranged on the upper surface of the base plate. The pulley is arranged on the lower surface of the vertical baffle. The vertical baffle is vertically connected to the slide rail through the pulley. The vertical baffle is connected to the base plate through the fixing bolt.
[0048] The thrust module 102 is disposed below the U-shaped bracket 101 . The thrust module 102 is connected to the control module 103 .
[0049] The sensor acquisition module 104 is disposed on both sides of the vertical baffle and is connected to the control module 103 .
[0050] The control module 103 is connected to the power module 105. The power module 105 is used to connect to an external engine.
[0051] In this embodiment, the U-shaped bracket 101 is used as the basic supporting structure of the entire turbojet engine test platform 100, and adopts an ingenious structural design, taking into account flexibility and stability. The U-shaped bracket 101 is a platform for placing an external engine, which can be made of aluminum material, and its surface is hard-oxidized to extend its service life.
[0052] Figure 2 is a schematic structural diagram of a turbojet engine test platform 100 provided by another embodiment of the present disclosure, referring to Figure 2 The components of the U-shaped bracket 101 may include: a slide rail, a bottom plate, a pulley, a vertical baffle and a fixing bolt. The slide rail is used in conjunction with the pulley. The slide rail is arranged on the upper surface of the bottom plate, and the pulley is arranged on the lower surface of the vertical baffle. The bottom plate and the vertical baffle are combined by the slide rail and the pulley to ensure that the vertical baffle can slide on the slide rail through the pulley, thereby changing the accommodating size of the U-shaped bracket 101 to be suitable for external engines of different sizes and shapes. The bottom plate and the vertical baffle can be made of a relatively light aluminum metal material to ensure the firmness of the overall platform, for example, 7075 aluminum material.
[0053] The fixing bolts are fixed components provided to ensure the stability of the entire U-shaped bracket 101 structure and to prevent the vertical baffle from accidentally moving during the test. After the vertical baffle is moved to a suitable position, the vertical baffle can be fixed to the bottom plate by the fixing bolts. When the position of the vertical baffle needs to be readjusted, the fixing bolts can be removed to adjust the position of the vertical baffle.
[0054] The thrust module 102 is located below the U-shaped bracket 101 and is used to detect the thrust generated by the external engine, including not only the pressure of the external engine itself, but also the jet thrust generated by the external engine. The thrust module 102 is directly connected to the control module 103 and transmits the detected data directly to the control module 103. As the core control unit of the entire test platform, the control module 103 is the "brain" of the entire test platform. The control module 103 receives the collected data from each module, and accurately outputs the corresponding control instructions according to the preset test program or dynamic adjustment instructions, thereby regulating the working state of the external engine to detect different working states of the external engine. In addition, the control module 103 is also responsible for integrating all data and providing real-time test results to facilitate engineers to analyze and optimize engine performance.
[0055] The sensor acquisition module 104 is a module for collecting various performance parameters of the external engine. The sensor acquisition module 104 may include a variety of sensors, which are installed on both sides of the vertical baffle to monitor key parameters during the operation of the engine, such as temperature, pressure, vibration frequency, thrust output, etc. These data are crucial for evaluating the health status, performance and early fault warning of the engine. The sensor module transmits the collected data to the control module 103 in real time, so that the control module 103 can integrate the data and issue control instructions.
[0056] The power module 105 is a module used to provide necessary power support for the external engine to change the operating state of the external engine. The power module 105 may include but is not limited to electricity, hydraulic or air pressure supply to drive the external engine to start, operate and adjust a specific working state. The power module 105 can ensure the stability and controllability of power transmission during the entire test process. The control module 103 analyzes the real-time data transmitted from the sensor acquisition module 104 and the thrust module 102, and sends corresponding control instructions to the power module 105 to control the power module 105 to change the power output to the external engine. The control module 103 can also select the corresponding power output source according to the different models of the external engine to ensure that the external engine can obtain matching power support.
[0057] It can be concluded from the above that the turbojet engine test platform 100 realizes the real-time data collection process of the external engine through the integrated sensor acquisition module 104 and the thrust module 102, and realizes the flexible adjustment of the external engine placement platform through the U-shaped bracket 101, thereby improving the convenience of the test process, providing a convenient and lightweight test platform for the test of the external engine, helping to save operating costs and improve the convenience of testing.
[0058] In one embodiment of the present disclosure, the power module 105 includes:
[0059] A first DC regulated power supply and a second DC regulated power supply.
[0060] The control module 103 is connected to the first DC regulated power supply and the second DC regulated power supply respectively. The first DC regulated power supply and the second DC regulated power supply are both used to connect to an external engine.
[0061] In this embodiment, the power module 105 may include two independent DC regulated power supplies, a first DC regulated power supply and a second DC regulated power supply. The first DC regulated power supply and the second DC regulated power supply may be controlled by the control module. During different external engine test processes, different DC regulated power supplies provide stable and pure DC power to the external engine, ensuring that the external engine obtains reliable power support during the test process. The first DC regulated power supply and the second DC regulated power supply may be two power supplies of the same power, used to provide a backup power supply or a redundant power supply for the external engine; or they may be two power supplies of different powers, used to provide different power demand support for external engines of different models.
[0062] The control module 103 can make a judgment on the model, working state or test progress of the current external engine according to the data transmitted by the sensor module 104, and control the corresponding DC regulated power supply to provide power support for the external engine according to the judgment result, thereby dynamically adjusting and controlling the output of the two DC regulated power supplies to achieve precise control of the power supply to the external engine. For example, the control module 103 can choose to enable the first DC regulated power supply or the second DC regulated power supply according to different test stages (such as starting, boosting, stable operation or shutdown, etc.). For example, the control module 103 can judge the corresponding power supply demand of the external engine according to the various working parameters of the external engine sent by the sensor module 104, and thus choose to enable the first DC regulated power supply or the second DC regulated power supply to meet the power demand of the external engine under different working conditions.
[0063] It can be concluded from the above that this embodiment, by providing a dual power supply configuration, not only enhances the power supply flexibility and stability of the test platform, but also improves the diversity and depth of the test, providing more powerful support for the performance testing and research and development of turbojet engines.
[0064] In one embodiment of the present disclosure, the thrust module 102 includes:
[0065] Two support plates, spring supports and thrust sensors.
[0066] The two support plates are fixed by spring support. A thrust sensor is arranged in the middle area of the two support plates. The thrust sensor is connected to the control module 103.
[0067] In this embodiment, the thrust module 102 may include two support plates, namely an upper support plate and a lower support plate, which constitute the main structure of the thrust module 102 and are used to directly bear the thrust generated by the external engine. In order to reduce the weight of the two support plates and enhance the portability of the entire test platform, the two support plates may be two aluminum plates of the same size, for example, two aluminum plates of 300×300×15 in size. The two support plates may be fixed by spring supports to connect the two support plates, and the elastic properties of the spring are used to absorb and buffer the jet impact force generated when the engine is running, thereby protecting the entire test platform from damage. At the same time, because the compression amount of the spring can directly reflect the thrust size, the interference of non-thrust factors is reduced, which also makes the thrust measurement more accurate.
[0068] A thrust sensor can be set in the middle area of the two support plates. The thrust sensor is a key measuring element of the thrust module 102. It can directly sense and collect the thrust data generated by the external engine and convert it into an electrical signal. Through the high-precision thrust sensor, the change of the external engine thrust can be monitored in real time, providing direct and accurate data support for evaluating the engine performance. The thrust sensor transmits the collected thrust data to the control module 103 through a signal line or wirelessly. The control module 103 monitors the engine operating status based on these real-time data, evaluates the test results, and even automatically adjusts the test parameters or stops the test when necessary to ensure the safety and effectiveness of the test process.
[0069] It can be concluded from the above that the present embodiment can accurately measure the thrust of the external engine, effectively cope with the dynamic changes of the working state of the external engine during the test, improve the reliability and accuracy of the test, and provide solid technical support for the research and development and performance optimization of turbojet engines.
[0070] In one embodiment of the present disclosure, a turbojet engine test platform 100 further includes:
[0071] Timing module.
[0072] The control module 103 is connected to the timing module. The timing module is connected to the thrust sensor.
[0073] In this embodiment, the timing module is responsible for recording the time data during the test, including but not limited to the start time of the external engine, the test duration, the duration of a specific test phase, etc. Time data is essential for analyzing the change of engine performance over time, evaluating the engine start speed, recording the time point of key events, etc. The timing module can start, pause or stop timing according to the instructions of the control module 103 to ensure that the collection of time data is closely synchronized with the test process. In addition, the control module 103 can also adjust the test process based on the time data, for example, automatically adjust the test parameters or trigger the next test phase at a predetermined time point.
[0074] The timing module can also record the acquisition time of the thrust sensor by connecting to the thrust sensor, and realize the process of periodically marking the data uploaded by the thrust sensor by setting the acquisition cycle. For example, the timing module can synchronously record the thrust change detected by the thrust sensor and the corresponding time point. When the set acquisition cycle is reached, the timing module sets a time mark for the data currently collected by the thrust sensor to ensure that the collected data received by the control module 103 is distributed according to the periodic law, which is convenient for the control module 103 to process and integrate the data.
[0075] It can be concluded from the above that the present embodiment can provide detailed thrust-time data through the timing module, provide a data sorting cycle for the control module 103, and provide a more accurate time dimension analysis for external engine performance evaluation, fault diagnosis and optimization design, which is another important improvement to improve the efficiency and accuracy of engine testing.
[0076] In one embodiment of the present disclosure, a turbojet engine test platform 100 further includes:
[0077] Infrared receiving module.
[0078] The infrared receiving module is used to receive external signals and is connected to the control module 103 .
[0079] In the present embodiment, the infrared receiving module is a wireless communication component specially designed to receive infrared signals emitted from the outside. Infrared communication is widely used in the field of short-range wireless control because of its simplicity, low cost and low resistance to electromagnetic interference. The infrared receiving module can be used to capture instructions from an external remote controller, an automated test system or other infrared signal transmitting devices. For example, these signals may include commands such as starting a test, stopping a test, adjusting test parameters, and emergency shutdown, making the operation of the test platform more flexible and safe. The infrared receiving module decodes the received infrared signal via the infrared receiving module and transmits it directly to the control module 103. The control module 103 adjusts the working state of the test platform in real time according to the received instructions, for example, changes the monitoring parameters of the sensor, starts the timing module recording, changes the power source, etc., to achieve remote control and automated management of the test process.
[0080] It can be concluded from the above that, by integrating an infrared receiving module, this embodiment enables the turbojet engine test platform 100 to respond to external instructions and execute complex test procedures with little or no human intervention, thereby improving test efficiency and reducing potential risks of manual operation, while also providing technical support for remote monitoring and intelligent management.
[0081] Reference Figure 2 In one embodiment of the present disclosure, a turbojet engine test platform 100 further includes:
[0082] Multiple displays.
[0083] The control module 103 is connected to a plurality of display screens respectively. The plurality of display screens are used to display various parameters collected by the sensor collection module 104 respectively.
[0084] In this embodiment, in order to provide a more comprehensive and multi-dimensional display of test data. Multiple display screens can be set, and each display screen can focus on displaying one or several types of key information, so that testers can quickly and intuitively monitor the key parameters during the engine test. The control module 103, as the center of information processing and instruction issuance, can be connected to each display screen and is responsible for transmitting a large amount of data collected from the sensor acquisition module 104 and the thrust module 102 to each display screen in real time according to the preset display logic and format. Each display screen is used to display the various parameters collected by the sensor acquisition module 104, for example, the display parameters may include but are not limited to engine thrust, temperature, pressure, vibration amplitude, fuel consumption rate, speed, etc. Each display screen can correspond to a display parameter, so that the tester can intuitively see the current working status of the external engine.
[0085] It can be concluded from the above that the multi-screen display design in this embodiment allows the tester to monitor the changes of multiple parameters at the same time, facilitate comparative analysis, and quickly identify abnormal conditions, so as to make timely adjustments or decisions during the test process. In this way, the setting of multiple display screens not only improves the operational convenience and richness of data visualization of the test platform, but also provides a more intuitive test data observation window for testers, which helps to deeply analyze engine performance, speed up the test process, and ensure the accuracy of test results and the efficiency of the test process.
[0086] In one embodiment of the present disclosure, the sensor acquisition module 104 includes:
[0087] Temperature sensor, speed sensor.
[0088] The temperature sensor and the rotation speed sensor are respectively arranged on both sides of the vertical baffle.
[0089] The temperature sensor and the rotation speed sensor are both connected to the control module 103 .
[0090] In this embodiment, the sensor acquisition module 104 may include a variety of sensors, among which the most important sensors may be temperature sensors and rotational speed sensors. These two sensors may be installed on both sides of the vertical baffle of the U-shaped bracket 101, respectively. Such a layout is conducive to directly collecting the temperature and rotational speed of the external engine placed on the U-shaped bracket 101, sensing the temperature changes and rotor speed during engine operation, and providing real-time and accurate measurement data.
[0091] Temperature sensors monitor the thermal conditions of the external engine and the surrounding environment, and are key components for evaluating the efficiency of external engine thermal management and preventing overheating. Speed sensors monitor the rotation speed of the external engine rotor, and are essential for ensuring the normal operation of the external engine and optimizing engine performance.
[0092] The temperature sensor and the speed sensor transmit the collected data to the control module 103 in real time to ensure that the collected data can be processed quickly. The control module 103 can display these parameters in real time to help the tester monitor the working status of the external engine, and automatically adjust the test parameters or issue an early warning based on these data. For example, when the temperature is too high or the speed is abnormal, the control module 103 can take braking measures in time to ensure that the test is carried out safely, and issue a corresponding buzzer alarm to remind the tester that the current external engine state is abnormal. For example, the control module 103 can also adjust the power module 105 to select the corresponding voltage-stabilized current source according to the data such as the temperature and speed of the external engine, and provide a matching power source for the external engine to ensure the normal progress of the test.
[0093] It can be concluded from the above that the present embodiment is capable of capturing the key parameters of the external engine operation in an all-round and high-precision manner, providing solid data support for the turbojet engine test platform 100, ensuring the efficiency and safety of the test process, and providing a reliable basis for engine performance optimization and fault diagnosis.
[0094] In one embodiment of the present disclosure, a turbojet engine test platform 100 further includes:
[0095] Multiple signal converters.
[0096] The temperature sensor and the rotation speed sensor are respectively connected to a plurality of signal converters in a one-to-one correspondence.
[0097] The plurality of signal converters are all connected to the control module 103 .
[0098] In this embodiment, the system is configured with multiple signal converters in view of the signal characteristics of the temperature sensor and the speed sensor. The function of the signal converter is to convert the original analog signal output by the sensor (such as the voltage change of the temperature sensor, the pulse signal of the speed sensor, etc.) into a digital signal after amplification, so as to facilitate the control module 103 to process and analyze the fault more efficiently and accurately. The temperature sensor and the speed sensor are directly connected to a signal converter respectively. Such a design ensures the specificity and accuracy of signal transmission, avoids signal crossing or confusion, and improves the reliability and real-time performance of data processing.
[0099] The multiple signal converters transmit the converted digital signals to the control module 103. Based on the digitalized precise information, the control module 103 can quickly respond and execute corresponding control strategies, such as adjusting test parameters, monitoring engine operating status, recording test data, etc. The control module 103 processes digital signals faster and more conveniently than analog signals, ensuring the high efficiency of the control module 103.
[0100] It can be concluded from the above that, by integrating multiple signal converters, the turbojet engine test platform 100 in this embodiment realizes efficient digitization of sensor signals, which not only improves the data processing speed, but also enhances the system's ability to accurately monitor engine operating parameters, providing a more solid data foundation for engine performance evaluation, fault diagnosis and optimized design.
