Description

Technical Field

[0001] This invention belongs to the field of aircraft technology and relates to a method for determining equipment parameters for advanced aerodynamic layout aircraft. Background Technology

[0002] Advanced aerodynamic configuration aircraft refer to aircraft with innovative aerodynamic layouts (shape characteristics) that differ from conventional layouts. Examples include waverider aircraft, tiltrotor aircraft, variable configuration aircraft, and C-wing aircraft.

[0003] In the past, the demonstration and conceptual design of advanced aerodynamic layout aircraft typically followed a design process of "researching requirements - comparing parameters of competing models - forming overall equipment parameters." However, given the unclear future combat application prospects and uncertain system contribution of advanced aerodynamic layout aircraft, equipment design has certain limitations on the application of advanced aerodynamic layout characteristics and subsequent modifications and innovations. Furthermore, existing aircraft equipment design processes have low correlation with operational requirements, operational simulation, and adaptability to application scenarios. Therefore, it is necessary to iteratively combine operational scenario design, operational simulation, and effectiveness evaluation to form a forward-looking equipment development process for advanced aerodynamic layout aircraft. Summary of the Invention

[0004] The technical problem solved by this invention is to overcome the shortcomings of the prior art and propose a method for determining equipment parameters for advanced aerodynamic layout aircraft. This method realizes the combined application of advanced layout aircraft design with combat simulation and performance evaluation, and meets the urgent engineering needs of organically integrating the overall demonstration, aerodynamic design, combat simulation, performance evaluation, and future battlefield application of advanced layout aircraft.

[0005] The solution of this invention is: a method for determining equipment parameters for advanced aerodynamic layout aircraft, comprising the following steps:

[0006] (1) Select a type of advanced aerodynamic layout aircraft as the target object and carry out data collection on the corresponding advanced layout aircraft, including the shape characteristics, RCS characteristics, fuselage internal volume, handling performance, lift-to-drag ratio and flight altitude under different conditions;

[0007] (2) Combat requirements are constructed by combining data collection results from advanced layout aircraft;

[0008] (3) Design operational application scenarios based on the established operational requirements;

[0009] (4) Based on the data collection results of advanced layout aircraft, carry out equipment model design;

[0010] (5) Utilize the results of equipment model design to carry out battlefield operation design for advanced layout aircraft;

[0011] (6) Based on the battlefield operation design of advanced layout aircraft and the corresponding combat application scenarios, a set of combat scenarios are formed;

[0012] (7) Use operational scenarios to adjust parameters and conduct the first round of large-sample operational simulation.

[0013] (8) Based on the results of the first round of large-sample combat simulation and the comparison of combat losses between the red and blue sides, conduct the second round of combat simulation and formulate new combat scenarios.

[0014] (9) Based on the designed combat application scenarios and the process and results of the second round of combat simulation, construct an indicator system for effectiveness evaluation and analysis;

[0015] (10) Through performance evaluation and analysis, aerodynamic parameters are assessed, equipment models are improved, flight paths are optimized, and battlefield operations are re-formed to achieve the adjustment of the new operational concept and equipment model parameters in step (8);

[0016] (11) Based on the effectiveness assessment analysis and the operational scenario adjusted in step (10), conduct the third round of simulation and make a judgment based on the results of the battle damage comparison. If the new battle damage ratio is higher than the previous battle damage ratio, return to step (10). If the battle damage ratio cannot be improved in multiple consecutive attempts, then based on the results of the last simulation, form a set of equipment parameters for advanced layout aircraft for engineering designers.

[0017] Furthermore, the design of the combat application scenario refers to selecting the combat location based on the three-dimensional map, selecting the position coordinates of the red and blue sides, the specific combat units, and the action rules and attack equipment usage rules of the combat units.

[0018] Furthermore, the equipment model design refers to the collection and encapsulation of data on the flight altitude, speed characteristics, infrared characteristics, stealth performance, load characteristics, damage points, and maneuverability of advanced layout aircraft.

[0019] Furthermore, the battlefield operation design of the advanced layout aircraft refers to combining the selected advanced layout aircraft's flight altitude, speed characteristics, stealth performance, and payload characteristics, and customizing flight routes according to the Blue Force's troop deployment, the reconnaissance capabilities of the main targets, and firepower deployment in specific application scenarios, so as to ensure that the aircraft has a survivability of no less than the preset level before it arrives at the predetermined action area to carry out fire strikes or detailed reconnaissance.

[0020] Furthermore, step (6) forms a set of operational scenarios, including:

[0021] Using commercial software, the battlefield operations of advanced deployment aircraft are edited and input, the deployment of red and blue forces is input, and the action rules and attack equipment usage rules of red and blue combat units are edited and input. The equipment models used are imported to form a set of combat scenarios.

[0022] Furthermore, the parameter adjustment and the first round of large-sample combat simulation exercises include:

[0023] The simulation analysis is conducted for each change in the location of the red and blue forces deployments; for each change in the number of red and blue forces deployments; and for each change in the reconnaissance and strike payloads carried by the red and blue combat units. Ultimately, a large-sample combat simulation is formed, creating a simulation database.

[0024] Furthermore, the second round of combat simulation exercises includes:

[0025] Based on the results of the first round of large-sample combat simulation exercises and the resulting simulation database, a comparison of battle damage assessments was conducted. In a series of scenarios involving changes to the deployment positions of both Red and Blue forces, no more than five deployment positions were selected based on the optimal battle damage comparison. Similarly, in a series of scenarios involving changes to the number of Red and Blue forces, no more than five deployment numbers were selected based on the optimal battle damage comparison. Furthermore, in a series of scenarios involving changes to the reconnaissance and strike payloads carried by Red and Blue combat units, no more than five payload arrangements were selected based on the optimal battle damage comparison. All selected scenarios were then randomly combined and filtered using battle damage assessments to conduct a second round of combat simulation exercises, resulting in new combat scenarios.

[0026] Furthermore, the construction of the indicator system for performance evaluation and analysis includes:

[0027] Based on the second round of combat simulation and results, the following indicators were extracted: battlefield action time of equipment units, communication quality of command and control links throughout the entire combat process, communication quality of communication links between combat units throughout the entire combat process, and average time of combat unit kill links. An indicator system was constructed, and firstly, multiple experts used the analytic hierarchy process to obtain the ranking vector containing each indicator. Then, expert cluster analysis was used to obtain the weight of each indicator. Based on the obtained indicator weights and ranking vectors, effectiveness evaluation methods were selected to complete the effectiveness evaluation analysis, including the ADC method, the TOPSIS method, and the weighted summation method.

[0028] Furthermore, the analysis of aerodynamic parameters, improvement of equipment models, optimization of flight paths, and re-formation of battlefield operations include:

[0029] After conducting combat simulation tests, it was found that the combat effectiveness was low due to the impact of the combat radius of the advanced layout aircraft. Therefore, the aerodynamic parameters were modified, including the lift-to-drag ratio and drag coefficient. Combining fuel consumption, flight speed, and velocity parameters, the combat radius was directly calculated and the model parameters in the equipment model library were modified.

[0030] After conducting combat simulation tests, it was found that the reconnaissance radius or accuracy of the advanced layout aircraft combined with the payload was insufficient. Therefore, modifications were made to the internal volume of the fuselage and the weight of the effective payload. The internal reconnaissance payload or strike payload was directly calculated and solved, and the model parameters in the equipment model library were modified.

[0031] Based on the modified aerodynamic parameters, overall parameters, and changes in combination parameters, the equipment model is modified; based on the designers' experience, the flight path of the advanced layout aircraft is optimized by changing the flight heading and altitude parameters, and battlefield operations are re-formed.

[0032] The advantages of this invention compared to the prior art are:

[0033] (1) This invention refines a design method for advanced aerodynamic layout aircraft equipment parameters, combining the design and development of advanced aerodynamic layout aircraft, aerodynamic design of aerodynamic layout, and combat simulation design. This method avoids the disconnect between aerodynamic layout design, overall parameter demonstration, and combat simulation, performance evaluation, and combat application scenario design in the previous process of advanced aircraft design and development. Meanwhile, with the continuous innovation of aircraft aerodynamic layouts, the existing design process of "researching requirements - comparing parameters of competing aircraft models - forming overall equipment parameters" is becoming increasingly restrictive. Therefore, this method, which combines advanced aerodynamic layout aircraft design with combat simulation and performance evaluation, forms a set of means for forward design of equipment parameters. It provides parameterized support for some advanced aerodynamic layouts and overall parameter indicators at the combat simulation level and performance evaluation level, which helps to realize the future concept of advanced layout aircraft.

[0034] (2) Compared with the prior art, the present invention innovatively incorporates important influencing factors such as combat scenarios, and conducts quantitative analysis of the future application of advanced layout aircraft in the early stage of design.

[0035] (3) Based on the characteristics of advanced layout aircraft and the customized combat scenarios, this invention incorporates performance evaluation and quantitatively describes the research direction of key aerodynamic parameters of advanced aerodynamic layout aircraft.

In the process of performance evaluation, important parameters of advanced aerodynamic layout are introduced to further realize the tight coupling between the two. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] This invention proposes a method for determining equipment parameters for aircraft with advanced aerodynamic layouts, such as... Figure 1 As shown, the steps are as follows:

[0042] (1) Select an advanced aerodynamic layout aircraft as the target object and carry out data collection on the corresponding advanced layout aircraft, including the layout's shape characteristics, RCS characteristics, fuselage internal volume, handling performance, lift-to-drag ratio under different conditions, flight altitude, etc.

[0043] (2) Combine the data collection results of advanced layout aircraft to construct operational requirements.

[0044] (3) Design operational application scenarios based on the operational requirements.

[0045] Operational application scenario design refers to selecting the combat location based on a 3D map, determining the position coordinates of both the red and blue sides, the specific participating units, and the rules for action and use of combat equipment for the combat units.

[0046] (4) Based on the data collection results of advanced layout aircraft, carry out equipment model design.

[0047] Equipment model design refers to the collection and encapsulation of data such as flight altitude, speed characteristics, infrared signature, stealth performance, load characteristics, damage points, and maneuverability of advanced layout aircraft.

[0048] (5) Utilize the results of equipment model design to conduct battlefield operation design for advanced layout aircraft.

[0049] Battlefield operation design for advanced layout aircraft refers to combining the selected advanced layout aircraft's flight altitude, speed characteristics, stealth performance, and payload characteristics, and customizing flight routes according to the Blue Force's force deployment, the reconnaissance capabilities of the main targets, and firepower deployment in specific application scenarios, to ensure that the aircraft has a survivability of no less than the preset level before it arrives at the predetermined operational area to carry out fire strikes or detailed reconnaissance.

[0050] In the detailed design of battlefield operations, the focus should be on describing the flight trajectory of advanced layout aircraft, which includes, but is not limited to, the aircraft's takeoff and landing, flight path, and changes in flight altitude.

[0051] The flight trajectory accuracy formed by advanced layout aircraft is no higher than 10. 1 The accuracy requirement for combat operations is at the second level, and for other equipment, the time accuracy requirement is no higher than 10 seconds. 2 Seconds.

[0052] (6) Based on the battlefield operation design of advanced layout aircraft and the corresponding combat application scenarios, a set of combat scenarios are formed.

[0053] Specifically, using commercial software, the battlefield operations of advanced deployment aircraft are edited and input, the deployment of red and blue forces is input, and the action rules and attack equipment usage rules of red and blue combat units are edited and input. The equipment models used are then imported to form a set of combat scenarios.

[0054] (7) Use operational scenarios to adjust parameters and conduct the first round of large-sample operational simulation.

[0055] Based on the operators' experience and analysis, the location of the red and blue forces deployments was changed, and a simulation analysis was conducted for each change; the number of red and blue forces deployed was changed, and a simulation analysis was conducted for each change; the important payloads carried by the red and blue combat units, namely reconnaissance and strike payloads, were changed, and a simulation analysis was conducted for each change. This ultimately resulted in a large-sample combat simulation, forming a simulation database.

[0056] (8) Based on the results of the first round of large-sample combat simulation and the comparison of combat losses between the red and blue sides, conduct the second round of combat simulation and formulate new combat scenarios.

[0057] Based on the results of the first round of large-sample combat simulation exercises and the resulting simulation database, a comparison of battle damage assessments was conducted. In a series of scenarios involving changes to the deployment positions of both Red and Blue forces, no more than five deployment positions were selected based on the optimal battle damage comparison. Similarly, in a series of scenarios involving changes to the number of Red and Blue forces deployed, no more than five deployment numbers were selected based on the optimal battle damage comparison. Furthermore, in a series of scenarios involving changes to the important payloads carried by both Red and Blue combat units—namely, reconnaissance and strike payloads—no more than five deployment configurations of the important payloads carried by combat units were selected based on the optimal battle damage comparison. All selected scenarios were randomly combined and further refined using battle damage assessments to conduct a second round of combat simulation exercises, resulting in new combat scenarios.

[0058] (9) Based on the designed combat application scenarios and the second round of combat simulation and results, construct an indicator system for effectiveness evaluation and analysis.

[0059] Specifically, it includes:

[0060] Based on the second round of combat simulation and results, a series of indicators and parameters were extracted, including the battlefield action time of advanced equipment units, the communication quality of the command and control link throughout the entire combat process, the communication quality of the communication link between combat units throughout the entire combat process, and the average time of the combat unit kill link. An indicator system was constructed, and firstly, multiple experts used the analytic hierarchy process to obtain the ranking vector containing each indicator. Then, expert cluster analysis was used to obtain the weight of each indicator. Based on the obtained indicator weights and ranking vectors, an effectiveness evaluation method was selected to complete the effectiveness evaluation analysis.

[0065]

[0066] (10) Through performance evaluation and analysis, aerodynamic parameters are assessed, equipment models are improved, flight paths are optimized, and battlefield operations are re-formed to achieve fine-tuning of the new operational concept and equipment model parameters in step (8).

[0067] The fine-tuning for the new operational scenario mainly includes: adjusting the flight path of advanced layout aircraft, modifying operational doctrine and the rules for the use of strike equipment; the fine-tuning for equipment model parameters mainly includes: modifying the combat radius, fuel consumption and RCS of advanced layout aircraft under various flight conditions.

[0068] Specifically, such as Figure 2 As shown, the analysis of aerodynamic parameters, improvement of equipment models, optimization of flight paths, and re-formation of battlefield operations include:

[0069] For example, after conducting combat simulation tests, it was found that the combat effectiveness was low due to the impact of the combat radius of advanced layout aircraft. The resulting aerodynamic parameters, such as lift-to-drag ratio and drag coefficient, can be modified. Combined with parameters such as fuel consumption, flight speed, and velocity, the combat radius can be directly calculated and the model parameters in the equipment model library can be modified.

[0070] For example, after conducting combat simulation tests, it was found that the reconnaissance radius or accuracy of the advanced layout aircraft combined with the payload was insufficient (or the cost-effectiveness of our side in striking enemy targets was not high). Therefore, parameters such as the internal volume of the fuselage and the weight of the effective payload can be modified to directly calculate and solve the reconnaissance payload or strike payload carried inside, and the model parameters in the equipment model library can be modified.

[0071] In summary, the equipment model was modified based on the altered aerodynamic and overall parameters, as well as the changes in the combined parameters. Based on the designers' experience, the flight path of the advanced layout aircraft was optimized by changing parameters such as flight heading and altitude, thus reshaping its battlefield operations.

[0072] Furthermore, in the newly formed operational scenario in step (8), the flight path and battlefield actions of the advanced layout aircraft are modified to form a new operational scenario.

[0073] (11) Based on the effectiveness assessment analysis and the operational scenario formed after the adjustment in step (10), conduct the third round of simulation and make a judgment based on the results of the battle damage comparison. If the new battle damage ratio is higher than the previous battle damage ratio, return to step (10). If the battle damage ratio cannot be improved in 7 or more consecutive times, then based on the results of the last simulation, form a set of equipment parameters for advanced layout aircraft for engineering designers.

[0074] This invention utilizes Figure 1 The design process shown is based on the corresponding battlefield environment, combat system, and a series of combat simulations and effectiveness evaluations conducted through a supporting simulation platform, ultimately forming a set of equipment parameters for an advanced aerodynamic layout aircraft.

[0075] Furthermore, given the strong battlefield application requirements of advanced aerodynamic layout aircraft in future battlefields, operational simulations can be used to design combat operations. A corresponding indicator system can be constructed, and the results of effectiveness evaluations can be used as feedback to refine the operational design. Through multiple iterations, the equipment parameters of the advanced aerodynamic layout aircraft can be ultimately determined. Utilizing this method to complete the forward design process for the equipment design of advanced aerodynamic layout aircraft has significant engineering implications.

[0076] This invention, through in-depth analysis and summarization of the equipment characteristics of various advanced aerodynamic layout aircraft, utilizes new battlefield applications to define the battlefield functions of advanced aerodynamic layout aircraft and extracts the characteristic elements of advanced aerodynamic layout aircraft equipment units based on simulation results. It then conducts joint design of the characteristics and application scenarios of advanced aerodynamic layout aircraft equipment units, combining data from combat simulation and performance evaluation, to effectively support the future development direction of advanced aerodynamic layout aircraft equipment, the refinement of key technologies, and the development of engineering prototypes.
