In the past, most of the calculations and analyses focused on the performance parameters of the aircraft, lacking the combination with simulation deduction, effectiveness evaluation and other technical means, resulting in uncertainty in the system contribution of advanced layout aircraft when participating in red-blue confrontation. Therefore, it is necessary to conduct survivability evaluation of advanced layout aircraft to assist in design, thereby ensuring a high mission completion rate from the bottom up.

[0038] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] Figure 1 The flowchart of a method for evaluating the survivability of an advanced aerodynamic configuration aircraft is shown. The specific implementation steps of the method are as follows.
[0040] Step (1) selects a certain type of advanced aerodynamic layout aircraft as a target object, and collects data on the advanced layout aircraft, wherein the collected data includes at least one of the following: the appearance characteristics of the layout, RCS characteristics, fuselage internal volume, control performance, lift-to-drag ratio under different states, and flight altitude.
[0041] Advanced aerodynamic layout aircraft refers to aircraft that are different from conventional layouts and have advanced aerodynamic layouts (appearance characteristics), such as waverider layout aircraft, tilt-rotor aircraft, variable configuration aircraft, C-wing aircraft, etc.
[0042] In step (1), based on the selected advanced layout aircraft shape characteristics, determine the range of RCS characteristic values, the range of fuselage internal volume (determined based on actual digital model measurements), control performance score, maneuverability score, lift-to-drag ratio under different flight conditions (determined by CFD calculation based on digital model), confrontation radius, and flight altitude parameters.

If the new damage ratio is better than the previous damage ratio, the number, formation, and penetration route of the advanced layout aircraft (core confrontation unit) are changed, and the damage ratio of the simulation is compared, and the step (6) is returned to carry out iterative confrontation simulation. If the damage ratio cannot be improved for multiple consecutive times, the corresponding confrontation assumption is selected based on the last simulation result.
[0053] Step (7), using the adversarial simulation results of step (6), conduct performance evaluation analysis.
[0054] In step (7), based on the determined confrontation scenario, the effectiveness is evaluated using the ADC method, fuzzy comprehensive evaluation method, TOPSIS analysis method or SEA method.
[0055] Step (8), using the results of the performance evaluation analysis in step (7), analyze the survivability of the advanced layout aircraft.

[0058] Where P D is the probability of an aircraft being discovered at a certain location (simulation and statistical average), P T is the probability of an aircraft at a certain position being tracked (simulation and deduction statistical average value). LGH P is the probability that a missile or artillery shell is successfully launched, guided (or aimed) and hits an aircraft. K / H is the probability of damage to the aircraft when it is hit.
[0059] Step (9), using the results of the survivability analysis in step (8), analyze and correct the penetration flight profile of the advanced layout aircraft.
[0060] In the analysis process, refer to Table 1 and linearize each flight profile into segments to form take-off segment, cruise segment, penetration segment, etc. Linearize the geometric mean of parameters for each segment of the k-th flight profile, and calculate the maneuverability parameters, speed term (V max , H d ), fuel item (K m ) for comparative analysis, the data is extracted in sections and then brought into the efficiency calculation formula, and the efficiency is calculated according to the formula, and the weighted average solution is completed to obtain the efficiency of the kth flight profile The performance calculation formula is as follows:

[0066]
[0067] The range coefficient is used to reflect the drone's ability to stay in the air on the battlefield and has a significant impact on the drone's sustained combat capability. m is the maximum range of the fuel in the aircraft, and the calculation formula is:
[0068]
[0069] K is the reference range, which is selected according to the technical characteristics of the selected equipment.
[0070]
[0071] The calculated Sort by numerical value, and select one or more flight profiles (penetration trajectories) with low efficiency values of advanced layout aircraft, that is, Value lower than During the flight, the flight altitude, flight speed, overload, infrared characteristics, stealth performance, load characteristics, damage points, maneuverability and other equipment parameters of the advanced layout aircraft are improved and adjusted, and then return to step (5). After repeated corrections, when each penetration flight profile meets the requirements of not less than After the requirement is met, go to step (10).
[0072] Step (10), using the analysis results of survivability in step (9), preliminarily solidify the actions (penetration trajectory) of advanced layout aircraft, adjust the counter-cluster strategy, optimize the coordination mode of the counter-cluster, reconstruct the actions of non-advanced layout aircraft, and adjust the equipment model.
[0073] In step (10), a series of combat simulations are conducted based on the use of the advanced layout aircraft (core confrontation unit) in step (9). During the simulation, the deployment position, flight altitude, speed characteristics, and flight trajectory of the non-core confrontation unit are continuously adjusted.
[0074] The judgment is made based on the damage comparison results of the combat simulation (which can be done using war game simulation software). If the new damage ratio is higher than the previous damage ratio, the data of the non-core confrontation unit will continue to be adjusted. If the damage ratio cannot be improved for multiple consecutive times, the deployment position, flight altitude, speed characteristics, and flight trajectory of the non-core confrontation unit will be determined based on the last simulation result, and then the data will be entered into step (11).
[0075] Step (11), combined with the adjustment and correction of step (10), makes a final assessment of the survivability of the entire confrontation cluster.

This method is mainly used for survivability assessment in the confrontation simulation process of future new aviation aircraft, and is applicable to the field of aviation aircraft technology.
[0078] At the same time, due to the high uncertainty of the use of advanced aerodynamic layout aircraft in future confrontation environments, its survivability is extremely important in the confrontation process. With the help of confrontation simulation deduction, supporting indicator system, effectiveness evaluation and other auxiliary means, the survivability of the confrontation unit is combined with the confrontation action design (penetration trajectory, flight route, confrontation unit coordination, inter-machine communication, etc.), and a set of survivability assessment methods is formed for complex confrontation environments. The survivability assessment method can be used to assist in the formation of quantitative support for the battlefield action design of advanced aerodynamic layout aircraft. At the same time, the survivability assessment method can be used as a feedback means to correct the demonstration and design work of advanced aerodynamic layout aircraft, which has strong engineering significance and application prospects.

[0080] Compared with the existing survivability assessment method for advanced aerodynamic layout aircraft, the survivability assessment method for the original aircraft equipment has a low correlation with factors such as confrontation simulation, effectiveness assessment, and adaptability in the confrontation environment of high-intensity confrontation. The present invention has opened up a new idea for survivability assessment, which is combined with the equipment demonstration, development, and modification of advanced aerodynamic layout aircraft.
