[0051] In order to facilitate a clear description of the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and do not limit their sequence. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and "first", "second", etc. do not necessarily mean different.

[0052] It should be noted that in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present invention should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0053] In the present invention, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B may be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression below refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b or c may represent: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b and c may be single or multiple.

[0054] In the project of the virtual test run system for liquid rocket engines, since the transient working time of a liquid rocket engine is only about 4 seconds, within these about 4 seconds, there is a large amount of data information on the core components of the liquid rocket engine, including: sensor data, simulation data, etc. of components such as flow regulating valves, thrust chambers, and oxygen pumps. Among them, the simulation data is presented in the form of a three-dimensional geometric model and a three-dimensional field cloud map. Among them, the three-dimensional field cloud map changes more than 10 times per second. Through monitoring, it is found that 350MB of data volume is transmitted per second for the field cloud map.

[0055] When rendering this 350MB of data on a web page to generate a field cloud map, more than thirty thousand data points need to be processed per second, which consumes a large amount of CPU, GPU, and memory resources instantaneously. It is difficult to ensure the real-time rendering of the three-dimensional field cloud map using traditional technologies such as Unity3D.

[0056] To ensure the real-time rendering of the three-dimensional field cloud map, this application provides a method, device, equipment, and medium for displaying the field cloud map of a rocket engine, which will be described in detail one by one in the following embodiments.

[0057] Please refer to Figure 1 , Figure 1 which is the flowchart of the method for displaying the field cloud map of the rocket engine provided by the embodiment of this application.

[0058] As Figure 1 shown, the method for displaying the field cloud map of the rocket engine includes the following S101 to S107:

[0059] S101, during the test run of the liquid rocket engine, obtain the full-scale simulation data set during the test run of the liquid rocket engine.

[0060] The full-scale simulation data during the test run of the rocket engine refers to all relevant information about the engine performance, state, and environmental conditions collected through various sensors and measurement devices during ground testing. In the embodiment of this application, the sensors include but are not limited to temperature sensors, pressure sensors, vibration sensors, etc. The full-scale simulation data set includes various key parameters during the test run of the liquid rocket engine, such as combustion chamber pressure, turbine pump speed, fuel flow rate, thrust magnitude, and so on.

[0061] S102, from the full-scale simulation data set, determine the first simulation data corresponding to the first data point of the primary rocket engine model of the liquid rocket engine.

[0062] The primary rocket engine model of the liquid rocket engine refers to a rocket engine model with a relatively low level of detail set for the liquid rocket engine. In the embodiments of this application, for the liquid rocket engine, three rocket engine models with different levels of detail are respectively set, namely the high-level rocket engine model, the intermediate-level rocket engine model, and the primary rocket engine model. The rocket engine models with different levels of detail are successively constructed based on different levels of grid accuracy preset.

[0063] In the actual application process, the high-level rocket engine model includes 30,000 data points, the intermediate-level rocket engine model includes 9,000 data points, and the low-level rocket engine model includes 1,000 data points.

[0064] In order to construct different field cloud maps of different components of the rocket engine, it is first necessary to determine the data type corresponding to the field cloud map to be rendered, and then based on the corresponding data type, from the full-scale simulation data, and based on the position of the first data point in the liquid rocket engine, proportionally extract the first simulation data corresponding to the first data point from the full-scale simulation data set.

[0065] S103, according to the first simulation data, render the first data point, and generate and display the primary field cloud maps of each component of the liquid rocket engine.

[0066] The field cloud map of the rocket engine refers to the spatial distribution map of the physical field inside or around the rocket engine, and the physical field includes the temperature field, the pressure field, the velocity field, etc.

[0067] Specifically, the above S103 includes:

[0068] According to the first simulation data, determine the stress color values corresponding to each first data point of the primary rocket engine model; render the stress color values to the primary rocket engine model, and generate and display the primary field cloud maps of each component of the rocket engine.

[0069] That is, the physical quantity values of the first simulation data of each first data point are represented by stress color values, and then the corresponding field cloud map is formed.

[0070] In the actual application process, different physical quantities of different components of different rocket engines correspond to different field cloud maps. For example, for the oxygen pump of the rocket engine, there are an oxygen pump velocity field and an oxygen pump temperature field; for the regulator of the rocket engine, there are a regulator velocity field and a regulator pressure field; for the thrust chamber of the rocket engine, there are a thrust chamber pressure field and a thrust chamber temperature field.

[0071] S104, in response to the magnification operation on the primary rocket engine model, determine, from the full-scale simulation dataset, the second simulation data corresponding to the second data point of the intermediate rocket engine model of the liquid rocket engine.

[0072] The magnification operation on the primary rocket engine model refers to the magnification of the primary rocket engine model displayed on the web page through the mouse scroll wheel or control instructions, so that the primary rocket engine model on the web page is changed to an intermediate rocket engine model to optimize the detail level and accuracy of the rocket engine model, and further optimize the detail level and accuracy of the field cloud map.

[0073] Specifically, the process of determining, from the full-scale simulation dataset, the second simulation data corresponding to the second data point of the intermediate rocket engine model of the liquid rocket engine is similar to the process of determining the first simulation data in S102 above.

[0074] That is, first, it is necessary to determine the data type corresponding to the field cloud map to be rendered, and then, based on the corresponding data type, extract, from the full-scale simulation data, the second simulation data corresponding to the second data point in proportion based on the position of the second data point in the liquid rocket engine.

[0075] S105, render the second data point according to the second simulation data, and generate and display the intermediate field cloud map of each component of the liquid rocket engine.

[0076] Similar to S103 above, S105 includes:

[0077] According to the second simulation data, determine the stress color values corresponding to each second data point of the intermediate rocket engine model; render the stress color values to the intermediate rocket engine model, and generate and display the intermediate field cloud map of each component of the rocket engine. For the relevant parts, refer to the introduction of S103, and details will not be elaborated here.

[0078] S106, in response to the magnification operation on the intermediate rocket engine model, determine, from the full-scale simulation dataset, the third simulation data corresponding to the third data point of the advanced rocket engine model of the liquid rocket engine.

[0079] The magnification operation on the intermediate rocket engine model refers to the magnification of the intermediate rocket engine model displayed on the web page through the mouse scroll wheel or control instructions, so that the intermediate rocket engine model on the web page is changed to an advanced rocket engine model to optimize the detail level and accuracy of the rocket engine model, and further optimize the detail level and accuracy of the field cloud map.

[0080] Specifically, the process of determining the third simulation data corresponding to the third data point of the advanced rocket engine model of the liquid rocket engine from the full-scale simulation dataset is similar to the process of determining the first simulation data in S102 above.

[0081] That is, first, it is necessary to determine the data type corresponding to the field cloud map to be rendered, and then, based on the corresponding data type, extract the third simulation data corresponding to the third data point from the full-scale simulation data in proportion according to the position of the third data point in the liquid rocket engine.

[0082] It can be understood that during the operation of the intermediate rocket engine model, the enlarged advanced rocket engine model can be the model of the entire rocket engine or the model of a certain device inside the rocket engine.

[0083] For example, in an alternative embodiment of the present application, in response to the zoom operation on the intermediate rocket engine model, the simulation data corresponding to the third data point of the target device of the liquid rocket engine is determined from the full-scale simulation dataset.

[0084] For instance, when the rocket engine model is the model of the flow regulator of the rocket engine, the intermediate rocket engine model includes the flow regulator model. However, even if the flow regulator model is further enlarged, due to the limited size of the display interface, the enlarged flow regulator cannot clearly show the changes of the internal valves and the flow field changes of the flow regulator. At this time, the zoom operation on the flow regulator model can correspond to the enlargement of a device inside it, namely the internal valves, so that relevant technicians can more intuitively see the changes of the internal valves and the corresponding flow field changes.

[0085] S107, render the third data point according to the third simulation data, and generate and display the advanced field cloud maps of each component of the liquid rocket engine.

[0086] Similar to S103 and S105 above, S107 includes:

[0087] According to the third simulation data, determine the stress color values corresponding to each third data point of the advanced rocket engine model; render the stress color values to the advanced rocket engine model, and generate and display the advanced field cloud maps of each component of the rocket engine. For the relevant parts, refer to the introduction of S103, and details will not be elaborated here.

[0088] In summary, the method for displaying the field cloud map of a rocket engine provided by the embodiments of the present application determines the first simulation data corresponding to the primary rocket engine model of the liquid rocket engine from the full-scale simulation data set, and renders the primary rocket engine model and the primary field cloud map with a lower level of detail based on the first simulation data. Compared with the prior art, this rendering method can ensure the rendering and display of the primary field cloud map while reducing the data volume. At the same time, the LOD (Level of Detail) technology is adopted, and in cooperation with the zoom operation for the primary rocket engine model, the intermediate rocket engine model and the high-level rocket engine model, as well as the corresponding intermediate field cloud map and high-level field cloud map, are gradually displayed, realizing the accuracy adjustment of the field cloud map. This method is beneficial to improving the rendering efficiency and maintaining visual fidelity.

[0089] The embodiments of the present application also provide a device for displaying the field cloud map of a rocket engine.

[0106] Obtain sensor data collected by each sensor during the test run of the liquid rocket engine;

For the technical details not described in detail in this embodiment, reference can be made to the specific processing content of the method for displaying the field cloud map of the rocket engine provided in the above embodiments of the present application, and details will not be elaborated here.

[0113] It should be understood that the units in the above device can be implemented in the form of a processor invoking software. For example, the device includes a processor, the processor is connected to a memory, and instructions are stored in the memory. The processor invokes the instructions stored in the memory to implement any of the above methods or the functions of each unit of the device. The processor can be a general-purpose processor, such as a CPU or a microprocessor, etc., and the memory can be a memory inside the device or a memory outside the device.
