[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] like Figure 1 As shown, an embodiment of the present application provides a design method for an unmanned sub-drone in a mother-and-child type unmanned aerial vehicle system, comprising:

[0030] Step 101: Based on the target user survey results, determine the demand value of the user demand of the unmanned sub-machine; the user demand includes but is not limited to low cost, long flight time, multi-function, deployability, maintainability and survivability.

[0031] Step 102: In combination with the overall aircraft design theory and UAV design experience, determine the product design characteristics of the UAV related to the user needs; the product design characteristics include but are not limited to subsonic lift-to-drag ratio, fuel consumption rate, thrust-to-weight ratio, wing loading, deployment burden, payload, radar scattering area and electronic system power.

[0032] Step 103: Establish a correlation matrix reflecting user needs and the product design characteristics.

[0033] Step 104: Determine the evaluation result of each product design feature according to the demand value of the user demand and the correlation degree matrix.

[0034] Step 105: Sort the product design features according to the evaluation results to generate product design feature priorities.

[0035] Step 106: Design the unmanned sub-machine according to the product design feature priority.

[0036] In an exemplary embodiment, by quantitatively analyzing the correlation and priority between the requirements of the mother-child UAV system and the design features of the unmanned sub-machine, the design features with the greatest requirements for the mother-child UAV system, namely the key design features, are found out after data analysis and processing, so as to guide the designers to carry out the overall design work of the unmanned sub-machine and then develop the corresponding products.

[0037] Further investigation and research will be conducted to determine the application scenarios and mission objectives of the mother-child UAV system, and to preliminarily determine the mother aircraft, that is, the carrier of the unmanned sub-aircraft.

[0038] Based on the UAV design experience and basic aircraft design requirements, the product design features are listed; based on the specific application scenarios and mission objectives of the mother-child UAV system, user needs are summarized, and a quality house is established based on the above content. The quality house is as follows: Figure 2 Among them, in the user demand part, the difference from the existing analysis method is that the user demand of this application needs to include the matching demand between the mother machine and the child machine, that is, deployability, in order to design a drone that is more suitable for the mother-child drone system.

[0039] Based on design experience, the correlation between product design features, user demand weights, and the relationship between product design features and user needs are analyzed, and based on the above analysis results, the product design features are evaluated.

[0040] According to the above product design characteristics evaluation results, refer to the value of the evaluation results, determine the key important indicators, and carry out further overall design work of the unmanned sub-machine based on this.

[0041] In an exemplary embodiment, step 101 specifically includes: using the formula Determine the user needs of the drone; among them, P j is the demand value of the jth user demand; m is the total number of interviewees of the target users; n is the number of user demand items; P ij is the score given by the i-th target user to the j-th user requirement.

[0042] In an exemplary embodiment, step 103 specifically includes: determining a correlation value based on the degree of correlation between the user demand and the product design characteristics; the correlation degree includes strong correlation, moderate correlation and weak correlation; the correlation value of the strong correlation is equal to 9, the correlation value of the moderate correlation is equal to 3, and the correlation value of the weak correlation is equal to 1; and establishing a correlation degree matrix reflecting the user demand and the product design characteristics based on the correlation values.

[0043] In an exemplary embodiment, step 104 specifically includes: using the formula Determine the evaluation results of each product design feature; where P k is the evaluation result of the kth product design feature; n is the number of user requirements; P j is the demand value of the jth user demand; N jk The correlation value between the kth product design feature and the jth user requirement.

[0044] In an exemplary embodiment, step 105 specifically includes: sorting the evaluation results in order from large to small to obtain an evaluation result sequence; sorting the product design features corresponding to the evaluation result sequence according to the evaluation result sequence to determine a product design feature sequence; determining a product design feature priority according to the product design feature sequence; and the product design feature priority decreases in sequence according to the product design feature sequence.

[0045] In an exemplary embodiment, step 106 specifically includes: designing the unmanned sub-machine according to the product design feature priority and the correlation between the product design features; the correlation between the product design features includes positive correlation, weak correlation and negative correlation; the positive correlation means that when one product design feature is met, a product design feature that is positively correlated with the product design feature can also be met; the weak correlation means that there is a certain degree of correlation between the two product design features, but the impact is small; the negative correlation means that when one product design feature is met, a product design feature that is negatively correlated with the product design feature cannot be met.

[0046] Taking a transport aircraft airdrop type unmanned aircraft as an example, the design method for the unmanned aircraft in the mother-child type unmanned aircraft system provided by this application is used for overall design. The analysis results of the quality house are as follows: Figure 3 shown.

[0047] First, the application scenarios and mission indicators of the mother-child UAV system are designed. Combined with military needs, the airdrop UAV designed in this example will mainly perform reconnaissance and monitoring tasks, and there are a series of requirements for the UAV, such as long flight time and low cost. According to relevant research, the mother aircraft (i.e., carrier aircraft) uses the Y-9 medium-sized propeller transport aircraft, with a minimum speed of about 250km / h and an actual airdrop altitude of about 6000m.

[0048] Secondly, we enter the parameter index design part of the overall design of the unmanned aircraft. Based on design experience and actual use requirements, we put forward product design characteristics such as high subsonic lift-to-drag ratio and low fuel consumption rate, as well as user requirements such as low cost and long flight time, and establish a quality house, such as Figure 3 As shown, the deployability includes the requirement that the unmanned aircraft can be carried on the Y-9 medium propeller transport aircraft platform and complete the release and recovery operations.

[0049] In order to better understand the design method of the unmanned sub-machine in the mother-child unmanned aerial vehicle system of this application, a brief introduction to the basic method of quality house is now given. Quality house, also known as quality function deployment, is a systematic, user-driven quality assurance method based on maximizing user needs during product development. Its purpose is to quantitatively analyze the correlation and priority between user needs and design features, and find out the design features that contribute most to meeting user needs after data analysis and processing, that is, key design features, so as to guide designers to grasp the main contradictions.

[0050] The design method for the unmanned sub-drone in the mother-sub drone system of the present application is applied to an actual scenario, specifically including the following steps 201 to 207.

[0051] Step 201: Through industry and target user research, it is concluded that the requirements for this type of UAV include low cost, long flight time, versatility, deployability, maintainability, and survivability, which constitute the user demand part of the quality house, namely the "left wall" part.

[0052] Further research is conducted on the above user needs and the degree to which they need to be met by means of market questionnaires, etc. Each user scores each need according to the requirement that the sum of the weights is 1. Then the scores of different users on each need are averaged to obtain the final demand weight, and the calculation formula is as follows.

[0053]

[0054] Among them, P j is the demand value of the jth user demand, the larger the value, the more important it is; m is the total number of interviewees of the target users; n is the number of user demand items; Pij The score of the jth user demand by the ith target user; and the demands are sorted according to the weights to determine the demand level, i.e. the "right wall" part, where the smaller the number, the higher the level.

[0055] Step 202: In combination with the overall aircraft design theory and UAV design experience, list the product design features corresponding to user needs, that is, the "ceiling" part. It should be noted that these product design features must meet the characteristics of measurability and pertinence. In addition, the product design features correspond to user needs, which means that user needs have direct or indirect requirements for certain design performance indicators. For example, the user demand for low cost requires the unmanned sub-machine to have a low fuel consumption rate in order to achieve the effect of saving fuel and reducing costs; for another example, the user demand for long flight time requires the unmanned sub-machine to have a high subsonic lift-to-drag ratio and a low fuel consumption rate in order to achieve the purpose of long endurance.

[0056] Step 203: Establish a correlation matrix reflecting user needs and product design characteristics (i.e. Figure 2 The relationship matrix in ), that is, the "room" part. Figure 3 As shown in , the solid blue circles represent strong correlations between product design features, with a correlation value of 9; the hollow blue circles represent moderate correlations between product design features, with a correlation value of 3; and the hollow blue triangles represent weak correlations between product design features, with a correlation value of 1. The above correlation values ​​will be used for the analysis in step 204.

[0057] In addition, it should be noted that strong correlation, moderate correlation, and weak correlation only measure the degree of correlation between user needs and product design characteristics, that is, for the correlation function of abstract user needs and product design characteristics, the absolute value of its slope determines the degree of correlation between the two; and the specific judgment needs to be determined by designers based on experience.

[0058] Correlation analysis needs to consider the degree to which different companies meet user needs and reflect the relative importance of different user needs.

[0059] Step 204: The product design characteristic evaluation result, i.e., the "floor" part, is obtained according to the evaluation formula, and the evaluation formula is as follows.

[0060]

[0061] Among them, P k is the evaluation result of the kth product design feature; n is the number of user requirements; P j is the demand value of the jth user demand; N jk The correlation value between the kth product design feature and the jth user requirement.

[0062]

[0063] Step 205: Establish the correlation between product design characteristics that reflects the relationship between product characteristics and is judged based on design theory, that is, the "roof" part. Figure 3 As shown in , each cell represents the correlation between the product design characteristics corresponding to the row and column where it is located, where the meanings of the graphics filled in the cells are as follows: a black solid circle represents a positive correlation between product design characteristics, a black hollow circle represents a weak correlation between product design characteristics, and a black slash represents a negative correlation between product design characteristics.

[0064] The specific evaluation method mainly relies on the overall aircraft design experience. Positive correlation means that when one product design feature is met, another product design feature can also be met. Weak correlation is a type of positive correlation, but the impact between the two is relatively small. Negative correlation means that when one product design feature is more met, the degree of satisfaction of another product design feature will decrease.

[0065] It should be noted that there is no quantitative formula to distinguish between positive correlation and weak correlation, and designers can determine it based on experience and logical analysis. In addition, during the design process, the correlation analysis of this part can also be simplified to only distinguish between positive correlation and negative correlation.

[0066] For example, consider the relationship between high subsonic lift-to-drag ratio and low fuel consumption rate. When the subsonic lift-to-drag ratio is high, the aircraft's drag is small under a certain lift, and less fuel is consumed, so the fuel consumption rate can be lower. According to the above analysis, the more the aircraft meets the product design characteristics of "high subsonic lift-to-drag ratio", the more it can meet the "low fuel consumption rate", that is, the change of subsonic lift-to-drag ratio will directly affect the fuel consumption rate. Therefore, there is a positive correlation between the two product design characteristics, which is represented by a black solid circle and filled in the cell where the two product design characteristics intersect. The analysis of moderate correlation and weak correlation is similar.

[0067] Step 206: Based on the evaluation results of step 204 and the correlation between the product design characteristics of step 205, preliminary values ​​are taken for each product design characteristic, i.e., the "basement" part. The specific values ​​are determined based on relevant design experience and some design methods, such as the energy constraint curve method, are used to determine the initial values.

[0068] This application includes qualitative user needs obtained through research; user demand weights and level evaluation obtained through research, which uses a certain comprehensive scoring formula to obtain an evaluation value; product features that are listed in combination with design theory and experience and correspond to user needs; a correlation matrix between product design features that reflects the relationship between product features and is judged based on design theory; a relationship matrix that reflects the degree of association between user needs and product design features; product design feature evaluation obtained according to the evaluation formula; and product design feature target values ​​that are preliminarily determined through various means and methods of design requirement demonstration.

[0069] Then, based on the above content, this example focuses on the deployability analysis part related to the innovation point. Take the analysis of deployability and small thrust-to-weight ratio as an example (thrust-to-weight ratio, that is, the ratio of aircraft thrust to weight, reflects the maneuverability of the aircraft). The speed of existing general drones is generally below 200km / h, and the thrust-to-weight of general long-flight drones is relatively low. However, in order to meet the launch and recovery requirements of the mother-child drone system, the drone sub-machine needs to have a certain acceleration capability. Therefore, there should be a negative correlation between the user demand for deployability and the small thrust-to-weight ratio, so this position in the relationship matrix is ​​empty.

[0070] Finally, according to the evaluation results of product design characteristics, the core design requirements of the unmanned sub-machine are determined to be low fuel consumption rate and small thrust-to-weight ratio. Therefore, in the subsequent design process, while meeting the basic deployment requirements, the thrust-to-weight ratio should be reduced as much as possible to better meet the system requirements. Similarly, in terms of speed index determination, in order to ensure that the unmanned sub-machine infiltrates and reaches the mission area as quickly as possible, and at the same time needs to meet the requirements of aerial recovery of the unmanned aircraft, the speed should be relatively high. At the same time, in order to reduce the fuel consumption rate, the speed index should not be too high. The minimum flight speed of the Yun-9 is about 250km / h. Combined with the indicators of the same type of unmanned aircraft, and with a certain redundancy, the maximum speed of the unmanned sub-machine is temporarily set at 300km / h.

[0071] The present application provides a method for designing an unmanned sub-machine in a mother-and-child unmanned aerial vehicle system, which is an overall design method for an unmanned sub-machine that takes into account the matching requirements between the unmanned sub-machine and the mother machine. It can help unmanned sub-machine designers better find important indicators in the design, so that the design scheme of the unmanned sub-machine can better adapt to the needs of the entire mother-and-child unmanned aerial vehicle system and exert better performance.

[0072] Specifically, the present application adds the matching requirements between the mother machine (i.e., user requirements) and the sub-machine to the existing quality house design method that does not consider the performance matching relationship between the unmanned sub-machine and the mother machine, and can quantitatively analyze the matching requirements, directly reflect the relevant requirements in the design indicator characteristic evaluation, and act on the determination of the target value of the product design characteristic, which is beneficial to the design of the unmanned sub-machine in the mother-child UAV system. At the same time, because the design method of the present application has a certain similarity in operation mode compared with the existing method, it will not increase the complexity of the design work while ensuring the design effect.

[0073] Based on the same inventive concept, the embodiment of the present application also provides a design device for an unmanned sub-machine in a mother-and-child unmanned aerial vehicle system for implementing the design method for an unmanned sub-machine in a mother-and-child unmanned aerial vehicle system involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more embodiments of the design device for an unmanned sub-machine in a mother-and-child unmanned aerial vehicle system provided below can refer to the limitations of the design method for an unmanned sub-machine in a mother-and-child unmanned aerial vehicle system above, and will not be repeated here.
