The specific computer device may include more or fewer components than those shown in the figure, or combine certain components, or have a different arrangement of components.

[0044] In one embodiment, Figure 2 As shown, Figure 2 is a flow chart of a pipeline design method provided in an embodiment of the present application, which can be applied to Figure 1 The computer device comprises the following steps:

[0045] S201, meshing the three-dimensional model of the engine to be designed to obtain a search space for external pipelines of the engine to be designed.

[0046] Optionally, a three-dimensional model of the engine to be designed input by the user may be obtained, and then the surface of the three-dimensional model may be meshed to obtain a search space for planning external pipelines.

[0047] S202: Obtain path parameters of the candidate paths between the starting points and end points of each input external pipeline.

[0048] The path to be selected is a path between a node and the next node of the external pipeline.

[0049] In one embodiment, the starting point, the end point, and the path parameters of the selected path between the starting point and the end point of the external pipeline input by the user may be obtained, wherein the path parameters of the selected path may include, for example, the pipeline diameter, the maximum corner angle, and the priority of the selected path.

[0050] For example, the start point Start, end point End of the external pipeline Pipe1, and the pipeline diameter Diameter, maximum corner angle MaxAngle, and priority Priority of the selected path input by the user can be described in the form of a script, as shown below:

[0051] Pipe1:

[0052] Start: (x1, y1, z1)

[0053] End: (x2, y2, z2)

[0054] Diameter: d1

[0055] MaxAngle: a1

[0056] Priority: p1

[0057] S203 , for each external pipeline, in the search space, determine a target path between a start point and an end point of the external pipeline according to path parameters of each candidate path of the external pipeline.

[0058] In one embodiment, for each external pipeline, a target path between a starting point and an end point of each pipeline may be determined according to path parameters of each candidate path corresponding to each external pipeline.

[0059] Exemplarily, the target path between the starting point and the end point of the external pipeline can be determined in the following manner: a "seed" can be created for the starting point of the external pipeline, the starting point of the external pipeline is used as a node to be processed, at least one candidate node that can be used as the next node of the node to be processed is determined, and then based on the A* algorithm and the vine growth strategy, according to the path parameters of each candidate path corresponding to each candidate node, the next node of the starting point, that is, the target node corresponding to the node to be processed, is determined from the candidate nodes, and the candidate path corresponding to the target node is used as the intermediate path. Afterwards, the next node of the starting point, that is, the target node corresponding to the node to be processed, can be used again as the node to be processed, and then the target node corresponding to the new node to be processed is determined based on the A* algorithm and the vine growth strategy, and the above steps are repeated until the target node corresponding to the latest node to be processed is the end point, and the target path is determined according to each intermediate path.

[0060] Among them, the path to be selected is the path formed between the node to be processed and the node to be selected, and the path parameters of the path to be selected include at least one of the path length and maximum corner angle of the path to be selected, the degree of fit between the path to be selected and the surface of the engine to be designed, and the distance between the path to be selected and other external pipelines.

[0061] S204: Determine the target path of each external pipeline as a pipeline design scheme for the engine to be designed.

[0062] In one embodiment, when all external pipelines reach the end point, that is, when all external pipelines determine the target path, the path coordinates of each target path can be determined, and the pipeline design scheme of the engine to be designed is generated according to each path coordinate.

[0063] In an embodiment of the present application, by gridding the three-dimensional model of the engine to be designed, a search space for the external piping of the engine to be designed is obtained, and path parameters of the candidate paths between the starting points and end points of each input external piping are obtained. Then, for each external piping, in the search space, a target path between the starting point and the end point of the external piping is determined according to the path parameters of each candidate path of the external piping, and the target path of each external piping is determined as the piping design scheme of the engine to be designed, thereby enabling automatic generation of a design scheme for the external piping of an aircraft engine that meets the design requirements, thereby improving design efficiency, saving design costs, and the accuracy and reliability of the external piping design can also be improved through the above method.

[0064] Reference Figure 3 , Figure 3 1 is a flow chart of a target path determination method provided by an embodiment of the present application. This embodiment relates to a possible implementation method of how to determine a target path between a starting point and an end point of an external pipeline according to the path parameters of each selected path of the external pipeline. Based on the above embodiment, the above S203 includes the following steps:

[0065] S301, determining at least one node to be selected corresponding to the node to be processed of the external pipeline.

[0066] The node to be processed is any node between the starting point and the end point of the pipeline except the end point.

[0067] Exemplarily, the starting point may be determined as the first node to be processed, and then at least one candidate node that may be the next node of the node to be processed is determined.

[0068] For example, if node A is determined to be the node to be processed, then nodes B, C, D, and E adjacent to node A may be determined as candidate nodes corresponding to node A to be processed.

[0069] S302 , according to the path parameters of the candidate paths corresponding to the candidate nodes, determine the target node corresponding to the node to be processed from the candidate nodes, and use the candidate paths corresponding to the target nodes as the intermediate paths.

[0070] Optionally, based on the A* algorithm and the vine growth strategy, according to the path parameters of the candidate paths corresponding to the candidate nodes, the target node corresponding to the node to be processed can be determined from the candidate nodes, and the candidate path corresponding to the target node can be used as the intermediate path.

[0071] In one embodiment, the starting point of the external pipeline can be used as the "seed" for the growth of the vine, and the growth direction of the vine can be determined from the starting point toward the end point. Specifically, determining the growth direction of the node to be processed means determining the target node corresponding to the node to be processed. The above-mentioned determination of the target node corresponding to the node to be processed from each node to be processed based on the path parameters of the path to be selected corresponding to the node to be selected based on the A* algorithm and the vine growth strategy can be achieved, for example, in the following manner: according to the weights of the path parameters of each path to be selected corresponding to the node to be selected and the path parameters of each path to be selected, the weighted summation result corresponding to the node to be selected is determined, and then according to the weighted summation result corresponding to each node to be selected, the target node is determined from each node to be selected.

[0072] Among them, the path to be selected is the path formed between the node to be processed and the node to be selected, and the path parameters of the path to be selected include at least one of the path length and maximum corner angle of the path to be selected, the degree of fit between the path to be selected and the surface of the engine to be designed, and the distance between the path to be selected and other external pipelines.

[0073] Exemplarily, the path between the to-be-processed node A and the to-be-selected node B is the to-be-selected path 1, the path between the to-be-processed node A and the to-be-selected node C is the to-be-selected path 2, the path between the to-be-processed node A and the to-be-selected node D is the to-be-selected path 3, and the path between the to-be-processed node A and the to-be-selected node E is the to-be-selected path 4. Then, the first weighted summation result corresponding to the to-be-selected node B can be determined according to the weight of the path parameter of the to-be-selected path 1 and the path parameter of the to-be-selected path 1, the second weighted summation result corresponding to the to-be-selected node C can be determined according to the weight of the path parameter of the to-be-selected path 2 and the path parameter of the to-be-selected path 2, the third weighted summation result corresponding to the to-be-selected node D can be determined according to the weight of the path parameter of the to-be-selected path 3 and the path parameter of the to-be-selected path 3, and the fourth weighted summation result corresponding to the to-be-selected node E can be determined according to the weight of the path parameter of the to-be-selected path 4 and the path parameter of the to-be-selected path 4. Then, the target node can be determined from each to-be-selected node according to the first weighted summation result, the second weighted summation result, the third weighted summation result, and the fourth weighted summation result.

[0074] S303, taking the target node as the node to be processed, and returning to the step of determining at least one candidate node corresponding to the node to be processed of the external pipeline, so as to determine the target node corresponding to the node to be processed, until the target node is the end point, and determining the target path according to each intermediate path.

[0075] In one embodiment, it can be determined whether the target node is the end point of the external pipeline. If the target node is not the end point of the external pipeline, the target node can be used as a new node to be processed, and then the above steps S301-S302 are returned to determine the target node corresponding to the new node to be processed until the target node is the end point, and then the intermediate paths are combined to obtain the target path.

[0076] In an embodiment of the present application, at least one candidate node corresponding to the node to be processed of the external pipeline is determined, and according to the path parameters of the candidate path corresponding to the candidate node, the target node corresponding to the node to be processed is determined from each candidate node, and the candidate path corresponding to the target node is used as the intermediate path, and the target node is used as the node to be processed, and the step of determining at least one candidate node corresponding to the node to be processed of the external pipeline is returned to determine the target node corresponding to the node to be processed, until the target node is the end point, and the target path is determined according to each intermediate path, so that the target path can be automatically determined based on the path parameters of the candidate path corresponding to the candidate node based on the A* algorithm and the vine growth strategy, and a design scheme for the external pipeline of the aircraft engine that meets the design requirements is obtained, thereby improving design efficiency and saving design costs. In addition, the accuracy and reliability of the external pipeline design can also be improved through the above method.

[0077] Reference Figure 4 , Figure 4 1 is a flow chart of a method for determining a target node provided by an embodiment of the present application. This embodiment relates to a possible implementation method of determining a target node corresponding to a to-be-processed node from each to-be-selected node based on the path parameters of the to-be-selected path corresponding to the to-be-selected node. Based on the above embodiment, the above S302 includes the following steps:

[0078] S401, determining a weighted sum result corresponding to the candidate node according to the weights of the path parameters of each candidate path corresponding to the candidate node and the path parameters of each candidate path.

[0079] Optionally, the path parameters of the path to be selected may include, for example, the path length and maximum corner angle of the path to be selected, the degree of fit between the path to be selected and the surface of the engine to be designed, and the distance between the path to be selected and other external pipelines.

[0080] Exemplarily, for the candidate path 1 between the node A to be processed and the candidate node B, the weights of each path parameter can be determined according to the importance of each path parameter of the candidate path 1, and then the weighted summation result corresponding to the candidate node B is determined by the weights of each path parameter of the candidate path 1, the path length and maximum corner angle of the candidate path 1, the degree of fit between the candidate path 1 and the surface of the engine to be designed, and the distance between the candidate path 1 and other external pipelines.

[0081] S402: Determine a target node from each candidate node according to the weighted summation result corresponding to each candidate node.

[0082] Optionally, the candidate node corresponding to the minimum weighted sum result may be determined as the target node. Alternatively, a preset threshold may be set, and the candidate node corresponding to the weighted sum result less than the preset threshold may be determined as the target node.

[0083] In an embodiment of the present application, a weighted summation result corresponding to a candidate node is determined based on the weights of the path parameters of each candidate path corresponding to the candidate node and the path parameters of each candidate path. A target node is determined from each candidate node based on the weighted summation result corresponding to each candidate node. This enables automatic determination of the target path, and obtains a design scheme for the external piping of an aircraft engine that meets the design requirements, thereby improving design efficiency and saving design costs. In addition, the above method can also improve the accuracy and reliability of the external piping design.

[0084] Based on the above embodiment, the above S402 can be implemented in the following manner:

[0085] The candidate node corresponding to the minimum weighted sum result is determined as the target node.

[0086] Exemplarily, the weighted sum results corresponding to the candidate nodes may be sorted, and then the candidate node corresponding to the minimum weighted sum result may be determined as the target node.

[0087] In an embodiment of the present application, the candidate node corresponding to the minimum weighted sum result is determined as the target node, so that the target path can be automatically determined, and a design scheme for the external piping of the aircraft engine that meets the design requirements is obtained, thereby improving the design efficiency and saving the design cost. The above method can also improve the accuracy and reliability of the external piping design.

[0088] Reference Figure 5 , Figure 5 FIG. 1 is a flow chart of another target node determination method provided by an embodiment of the present application. Based on the above embodiment, the method further includes the following steps:

[0089] S501: If the first target node corresponding to the first node to be processed is the same as the second target node corresponding to the second node to be processed, compare the first priority of the first external pipeline with the second priority of the second external pipeline.

[0090] The first node to be processed is a node to be processed of the first external pipeline, and the second node to be processed is a node to be processed of the second external pipeline.

[0091] In an embodiment of the present application, after each round of determining the target node, collision detection is required. If the first target node corresponding to the first node to be processed is the same as the second target node corresponding to the second node to be processed, it means that two different external pipelines have collided during the path selection process. At this time, the first priority of the first external pipeline and the second priority of the second external pipeline can be compared.

[0092] S502: If the first priority is higher than the second priority, determine the target node corresponding to the second node to be processed from other nodes to be selected.

[0093] The other nodes to be selected include the nodes to be selected corresponding to the second node to be processed except the second target node.

[0094] In one embodiment, if the first priority is higher than the second priority, it means that the priority of the first external pipeline is higher than the priority of the second external pipeline, and the second external pipeline triggers the bypass mechanism, that is, based on the above steps S301-S303, the target node corresponding to the second node to be processed is re-determined from other candidate nodes corresponding to the second node to be processed except the second target node.

[0095] In the embodiment of the present application, if the first target node corresponding to the first node to be processed is the same as the second target node corresponding to the second node to be processed, the first priority of the first external pipeline and the second priority of the second external pipeline are compared. If the first priority is higher than the second priority, the target node corresponding to the second node to be processed is determined from other nodes to be selected, so that when a collision is detected, the external pipeline with a low priority can be actively bypassed, avoiding conflicts between pipelines, and further improving the safety and reliability of the external pipeline design. At the same time, it avoids repeated rework due to collision problems after the design is completed, and improves the efficiency of external pipeline design.

[0096] Reference Figure 6 , Figure 6 1 is a flow chart of an automated design method for external piping of an aircraft engine provided in an embodiment of the present application. The method comprises the following steps:

[0097] S601, meshing the three-dimensional model of the engine to be designed to obtain a search space for external pipelines of the engine to be designed.

[0098] S602: Obtain path parameters of the candidate paths between the starting points and end points of each input external pipeline.

[0099] S603: Determine at least one node to be selected corresponding to the node to be processed of the external pipeline.

[0100] S604: Determine a weighted sum result corresponding to the candidate node according to the weights of the path parameters of each candidate path corresponding to the candidate node and the path parameters of each candidate path.

[0101] S605: Determine the candidate node corresponding to the minimum weighted sum result as the target node.

[0102] S606, taking the target node as the node to be processed, and returning to the step of determining at least one candidate node corresponding to the node to be processed of the external pipeline to determine the target node corresponding to the node to be processed, until the target node is the end point, and determining the target path according to each intermediate path.
