Background Art

[0002] As a sea-based take-off and landing platform for carrier-based aircraft, aircraft carriers have the characteristics of platform movement and limited space, which results in a fast speed, short time and high risk factor in the landing process of carrier-based aircraft, which is one of the main safety hazards of carrier-based aircraft and aircraft carriers. The Landing Signal Officer (Landing Commander) is the commander who issues control instructions to the pilots of carrier-based aircraft and guides them to land safely on the aircraft carrier during the landing process of carrier-based aircraft. He is an important safety guarantee for carrier-based aircraft and aircraft carriers. However, due to the short development time of carrier-based aircraft and aircraft carrier technology in China, the relevant training equipment for landing commanders is not ideal, which cannot reflect the unique flight simulation of carrier-based aircraft during the landing process and cannot cover various emergencies faced by landing commanders, resulting in the inability of landing commanders to obtain good training results in simulation training, which prolongs the training time of landing commanders.

[0031] The objective evaluation program (130) includes a landing command training evaluation standard set (131), a landing command training evaluation weight factor library (132) and a landing command training calculation matrix (133); the landing command training evaluation standard set (131) is used to provide a landing command training evaluation standard; the landing command training evaluation weight factor library (132) corresponds to each parameter in the landing command training evaluation standard set; the landing command training calculation matrix (133) inputs the simulation data generated in the landing command personnel training simulator, and can compare and identify the data with the landing command training evaluation standard, output the deviation of the command result of the landing command personnel trainee during training compared with the standard value, and then calculate the deviation result with the weight value in the weight factor library, and finally output the training result;

[0032] The landing command training evaluation standard set (131) includes carrier aircraft standard glide path information, carrier aircraft landing longitudinal deviation value allowable range, carrier aircraft landing lateral deviation value allowable range, carrier aircraft landing speed deviation value allowable range, landing command command quantification standard of landing commander, and go-around command quantification standard;

[0033] The standard glide path information of the carrier-based aircraft is used to calculate the position of the standard glide path of the carrier-based aircraft according to the land-based / carrier-based airport information;

[0034] The allowable range of the longitudinal deviation value of the carrier-based aircraft landing is to establish a proportional relationship between the longitudinal deviation of the carrier-based aircraft in the longitudinal direction compared with the standard glide path;

[0035] The allowable range of the lateral deviation value of the carrier-based aircraft landing is to establish a proportional relationship between different distances from the runway and the lateral deviation of the carrier-based aircraft in the lateral direction compared with the standard glide path;

[0038] The quantification standard of the missed approach command is the position and status index of the carrier-based aircraft at which the missed approach command should be issued when the carrier-based aircraft cannot land during the landing process;

[0040] The information-based call command weight factor includes a correct call command weight factor and a command delay weight factor. A corresponding weight is given for each command. According to the dimensions of longitudinal deviation, lateral deviation, posture deviation, and speed deviation, the corresponding weights of correct command, wrong command, and fast or slow timing of issuance are given.

When the carrier-based aircraft is at a position far from the runway, such as the initial section and the middle section, the corresponding weight factor value is small, that is, the deviation of the carrier-based aircraft at this stage has little impact on the landing command evaluation of the landing commander; as the carrier-based aircraft approaches, the corresponding weight factor is gradually increased to increase the impact of the carrier-based aircraft deviation on the landing command evaluation, reflecting the key observation and evaluation stage in the landing process;

[0049] The landing command command deviation calculation module is used to calculate the carrier aircraft simulation data, match the carrier aircraft position and state in the landing command training evaluation standard set, generate the command command standard that the landing commander should issue, and compare it with the actual information issued by the landing commander during training to determine the time delay and correctness;

[0050] The evaluation result calculation and output module calculates the delay and correctness of different command commands with the corresponding objective evaluation weight factor library, generates and outputs the landing command evaluation result of the landing commander.

[0051] like Figure 2 As shown, an objective evaluation method (200) for landing command simulation training adapted to approach distance in this embodiment further illustrates the content of this patent. The specific steps of the method (200) are as follows:

[0052] Step 1: The operation of the method can be started by external control (201), including the pilot model, flight simulation, three-dimensional scene simulation, operation page simulation and subsequent evaluation method operation;

[0053] Step 2: Perform pilot model manipulation simulation (202), during which flight simulation data and command commands issued by the user are received. If the training is not completed, the simulation is run periodically to complete the simulation of the pilot manipulation process.

[0054] Step 3: A six-degree-of-freedom simulation model of the aircraft is established. According to the simulation results of the pilot's operation, the flight simulation data is solved and sent (203). The aircraft's real-time longitude, latitude, altitude, pitch angle, roll angle, heading angle, airspeed, actuation surface deflection and other data can be calculated to support the operation of other models.

[0055] Step 4: Based on the flight simulation data, three-dimensional simulation scene generation (204), operation page simulation (205), deviation and standard command solution (206) are realized, wherein the three-dimensional simulation scene and operation page simulation can be presented through a commercial display to support the user to judge the deviation and issue a command command (207), and the command command can further affect the pilot model operation simulation (202);

[0056] Step 5: Further, the deviation and standard command settlement (206) in S4 is performed according to the deviation of the flight simulation data and the standard glide path, and the deviation is solved in real time and the command content issued by the corresponding deviation miniature is matched; further, according to the position information in the flight simulation data, the position distance of the aircraft relative to the ideal landing point is determined, and the corresponding weight factor is adjusted, and the weight value is reduced when the aircraft is far away, and the weight value is increased when the aircraft is close;

[0057] Step 6: When the user issues a command (207), it is compared with the standard command (206), the correctness and timeliness of the command (209) are evaluated, and the weight value of the corresponding distance is further matched (210);

[0058] Step 7: Determine whether the training process is finished (211). If not, return to the pilot model simulation process (202) loop. If the training is finished, obtain the final evaluation result and end this method.

[0059] Combine the following Figure 3 Taking the correctness evaluation process of the objective evaluation method for landing command simulation training adapted to the approach distance as an example, the content of this patent is further explained. The specific steps are as follows:

[0060] Step 1: Quantify the standard command indicators. The specific process is to clarify the deviation range corresponding to all commands. When the deviation of a certain indicator of the simulated aircraft is within a certain command deviation, the corresponding command should be issued;

[0061] Step 2: The landing command of the landing commander should be consistent with the standard command content, and the correctness score is Z (0-100 points);

[0062] The formula for calculating Z is as follows:

[0063]

[0064] Among them, n means that the landing commander issued a total of n instructions;

[0065] Represents the correctness evaluation coefficient. The correctness evaluation coefficient is determined by whether the content of the command issued by the landing commander is consistent with the content of the standard command. When the landing commander's command is consistent with the standard command, the correctness evaluation coefficient is =1 otherwise =0;

[0066] Step 3: When the landing commander does not issue a command, if the carrier-based aircraft lands normally, the correctness score Z=100; if it does not land normally, the correctness score Z=0;

[0067] Step 4: When the landing commander issues a command, if the landing is not normal, the correctness score Z=0; if the landing is normal, the command content is traversed to determine whether it is consistent with the corresponding standard command content, and determine , and finally weight all passwords to get the correctness score Z.

[0068] Combine the following Figure 4Taking the timeliness evaluation process of the objective evaluation method for landing command simulation training adapted to the approach distance as an example, the content of this patent is further explained. The specific steps are as follows:

[0069] Step 1: quantify the standard command timeliness index according to the distance between the carrier-based aircraft and the ship and the content of the command. The specific process is to clarify the corresponding delay time range of all commands. That is, when a certain indicator of the simulated aircraft deviates, the landing commander should issue the corresponding command. The time difference from the deviation to the issuance of the command is the delay scoring item.

[0070] Step 2: The landing commander's command should meet the timeliness requirements of the standard command, and the timeliness of the landing commander's command is represented by a timeliness score. The timeliness score is J (0-100 points), and the higher the score, the more timely the command;

[0071] The calculation formula of J is as follows:

[0072]

[0073] in

[0074] n means that n timeliness rating judgments occur, and the judgment is triggered at

[0075] 1. When the quantitative data moves from the interval without timeliness requirement to the interval with timeliness requirement;

[0076] 2. When the quantitative data moves from a low timeliness requirement interval to a high timeliness requirement interval;

[0077] 3. At the beginning of phase X;

[0078] 4. When you pass the AR stage;

[0079] represents the timeliness assessment coefficient;

[0080] Step 3: When the landing commander does not issue a command, if the carrier-based aircraft lands normally, the timeliness score J=100; if it does not land normally, the correctness score J=0;

[0081] Step 4: When the landing commander issues a command, if the landing is not normal, the timeliness score J=0; if the landing is normal, determine the number of timeliness command triggers m, if the trigger number is 0, then the timeliness score J=100, if not 0, continue with the subsequent calculation;

[0082] Step 5: Traverse each time node where timeliness trigger occurs, and determine whether the password timeliness trigger time at the current time point exceeds the allowed time range after the time point where the deviation occurs. If not, determine whether the next time point exceeds the allowed time range. When it exceeds the allowed time range or the traversal of each timeliness trigger time point is completed, proceed to the next step of calculation;

[0083] Step 6: Traverse the commands issued by the landing commanders and make judgments based on the time of each command. If it is within the command trigger time and the allowed range, the timeliness score of the command JS=1; if it is not within the range, determine whether the commands of all landing commanders have been traversed. If the traversal is not completed, proceed to the next command. If the traversal is completed, the command timeliness score J=100×SUM(JS) / time is obtained, and the calculation is completed.

[0084] Combine the following Figure 5 , to further illustrate the content of this patent, with an example of timeliness evaluation of an objective evaluation method for landing command simulation training adapted to the approach distance, the specific steps are as follows:

[0085] Step 1: When the offset or offset rate crosses multiple timeliness requirement zones within a timing interval, the higher level requirement zone (1s) is timed independently, and the timing end point with a tighter time is used as the timeliness determination end point. In the figure, command 1 is timely, and the timeliness evaluation coefficient is 1; command 2 is not timely, and the timeliness evaluation coefficient is 0;

[0086] Step 2: Figure 4 In the upper part of the figure, 1s is more urgent. The landing commander's command 1 is issued within 1s of "Start timing 2", and the evaluation result is timely, and the timeliness evaluation coefficient is 1. The landing commander's command 2 is issued within 3s of "Start timing 1", but not within 1s of "Start timing 2", and the evaluation result is untimely, and the timeliness evaluation coefficient is 0;

[0087] Step 3: Figure 4 In the lower part of the figure, 3s is more urgent. The landing commander's command 1 is issued within 3s of "Start timing 1", and the evaluation result is timely, and the timeliness evaluation coefficient is 1. The landing commander's command 2 is issued within 1s of "Start timing 2", but not within 3s of "Start timing 1", and the evaluation result is untimely, and the timeliness evaluation coefficient is 0.

[0088] This patent is an objective evaluation system and method for landing command simulation training that is adapted to the approach distance. By analyzing the objective factors of command evaluation in the landing command process, a landing command training evaluation standard set, a landing command training evaluation weight factor library, and a landing command training calculation matrix are established. The evaluation method for the correctness and timeliness of commands in the landing command process is clarified, and ultimately the objective evaluation results of the landing command are obtained to assist students in simulation training.
