[0002] Flight quality simulator testing utilizes advanced virtual simulation technology, precise electromechanical control devices, and a realistic audiovisual rendering system to create a simulated environment that closely resembles a real aircraft cockpit, reproducing a lifelike flight dynamic atmosphere. This enables human-environment flight quality assessment, allowing pilots to conduct in-depth and comprehensive testing of aircraft performance within a simulated environment. During flight quality simulator testing, the per-gram steady-state control force testing method is widely adopted. The core of this method is requiring pilots to perform step-like control stick actions. To ensure that flight quality across the entire flight envelope meets preset requirements, the test must establish a massive number of state points, directly leading to a significant increase in the scale of test data. Furthermore, manually processing the per-gram steady-state control force test data is not only time-consuming but also lacks accuracy, resulting in extremely low overall efficiency, far from meeting the standards of efficient testing.

[0012] Steady-state control force per g refers to the control force that the pilot needs to apply to the control stick (or control wheel) to generate and maintain each g increment of overload during a steady overload maneuver (i.e., steady-state maneuver).

[0013] In this embodiment of the invention, a method for identifying and evaluating test data of steady-state maneuvering force per gram is provided, such as... Picture 1 As shown, the method includes: Step S101: Preprocess the test data of steady-state control force per g collected from the flight quality simulator, remove erroneous data from the test data, generate preprocessed test data, and calculate the preprocessed test data of steady-state control force per g generated per second. The test data includes control stick displacement data, normal overload data, control stick force data, and flap deflection angle data. Step S102: Identify the action of each g steady-state control force using the preprocessed test data generated every second, and obtain the action of each g steady-state control force; Step S103: Using the test data of each g steady-state control force generated per second and the action of each g steady-state control force, perform equivalent fitting on the each g steady-state control force to generate a first ratio of overload to angle of attack change and a second ratio of overload to stick force change. Evaluate the flight quality of each g steady-state control force using the first ratio and the second ratio.

[0014] In specific implementation, the following steps are used to preprocess the test data of each g of steady-state control force collected from the flight quality simulator, remove erroneous data from the test data, generate preprocessed test data, and calculate the preprocessed test data of each g of steady-state control force generated per second: The test data of steady-state control force per gram, including time, is obtained from the flight quality simulator and sorted according to the time axis to generate time series data. Error judgment conditions are set if the time series data at a later time is less than the time series data at the current time, or if the difference between the time series data at a later time and the time series data at the current time is greater than a difference threshold. The time series data is traversed, and when the error judgment conditions are met, the time series data at the later time is truncated to generate corrected time series data. This corrected time series data is used as preprocessed test data. The test data of steady-state control force per gram generated per second is calculated using the corrected time series data and the corresponding total time.

[0015] In specific implementation, the following steps are used to identify the action of each g steady-state control force based on the preprocessed test data generated every second, and to obtain the action of each g steady-state control force: The control stick displacement data is divided into k segments. The start point, inflection point, and end point of each step control stick action are obtained to generate a segmented action group. Duplicate points in the start point and end point of the action are removed from the segmented action group. The start point, inflection point, and end point of the action are saved to the final segmented action group. The start point, inflection point, and end point of the action in the k segments of the final segmented action group are used as the action for each g steady-state control force.

[0016] In specific implementation, the control stick displacement data is divided into k segments through the following steps, and the starting point, inflection point, and ending point of the step control stick action corresponding to each segment are obtained: The control stick displacement data is divided into k segments, and the following processing is performed from the first segment to the kth segment: the control stick displacement data of the i-th segment is used to determine whether there is any action of the step control stick, where i is from 1 to k; if there is action, the starting point of the action of the control stick displacement data, the inflection point of the action of the control stick displacement data, and the ending point of the action of the control stick displacement data are obtained as the starting point, inflection point, and ending point of the action of the i-th segment.

[0017] In specific implementation, the following steps are used to perform equivalent fitting on the steady-state control force per gram by using the test data of the steady-state control force generated per second and the action of the steady-state control force per gram, thereby generating a first ratio of overload to angle of attack change and a second ratio of overload to lever force change: Effective stick force data is obtained by generating test data of steady-state control force per gram per second; The normal overload before the start of the action of each g steady-state control force is calculated using the action of each g steady-state control force, the normal overload data of the test data, the angle of attack data, and the effective control stick force data. Nz s Angle of attack before the start of the action α s The force of the control stick before the start of the action Fe s Normal overload after motion stabilization Nz e Angle of attack after the movement stabilizes α e and the control stick force after the action stabilizes Fe e ; through the force of the control stick Fe s The force of the control stick Fe e The normal overload Nz sand the normal overload Nz e The first ratio of overload to angle of attack change was calculated. ; through the aforementioned normal overload Nz s The normal overload Nz e The angle of attack α s and the angle of attack α e The second ratio of overload to change in rod force was calculated. .

[0018] In specific implementation, the following steps are used to calculate the normal overload before the start of the action of each g steady-state control force using the action of each g steady-state control force, the normal overload data of the test data, the angle of attack data, and the effective control stick force data. Nz s Angle of attack before the start of the action α s The force of the control stick before the start of the action Fe s Normal overload after motion stabilization Nz e Angle of attack after the movement stabilizes α e and the control stick force after the action stabilizes Fe es : The time period from 1 second before the start of the action to the start of the action is defined as the first time period. The normal overload data, angle of attack data, and effective control stick force data within this first time period are acquired. The average of the normal overload data within the first time period is taken as the normal overload before the start of the action. Nz s The mean of the angle of attack data is taken as the angle of attack before the start of the operation. α s The average value of the effective control stick force data is taken as the control stick force before the action begins. Fe s The time interval from the inflection point of the action to 5 seconds after the inflection point is designated as the second time interval. Based on the preprocessed test data of steady-state control force per second generated per gram, the sum of the differential slopes of overload data, angle of attack data, and effective control stick force per second within the second time interval is calculated. By adding the sums of the differential slopes of the overload data, angle of attack data, and effective control stick force, and taking the minimum value, the start and end points of the steady-state effective data action are determined and designated as the third time interval. The mean value of the normal overload data within the third time interval is taken as the normal overload after the action stabilizes. Nz e The mean of the angle of attack data is used as the angle of attack after the action has stabilized. α e The average value of the effective control stick force data is taken as the control stick force after the action is stabilized. Fe es .

[0019] In specific implementation, the flight quality of each g steady-state control force is determined by using the first ratio and the second ratio through the following steps: Based on the preprocessed flap deflection data, the flight phase to which the test data belongs is determined, wherein the flight phase includes the navigation phase and the takeoff and landing phase; the preset flight quality standards for each flight phase are obtained, and the first ratio and the second ratio are compared with the preset flight quality standards for the corresponding flight phase; according to the comparison results, the judgment result of the flight quality level per g steady-state control force is output, wherein the judgment result is the flight quality level.

[0020] In one embodiment of the present invention, the following steps are included: Step 1: Data preprocessing.

[0021] Step 1.1: Import the test data (including time series data, control stick displacement data, normal overload data, master control stick force data, co-pilot control stick force data, angle of attack data, and flap deflection data). Iterate through the time series data. If the time at position t0+1 is less than the time at position t0, or the time difference is greater than the threshold A, truncate all test data from position t0+1 and retain all data after that. If the condition is still not met after iterating to the end of the data, retain all test data and proceed to the next step.

[0022] Step 1.2: Compare the total amount of data L on the extracted time series data with the total time T and round down to obtain the amount of data per second.

[0023] The logic diagram of the data preprocessing process is as follows: Picture 2 As shown, the processed data is as follows Picture 3 As shown.

[0024] Step 2: Find and capture the steady-state control force action per g.

[0025] Step 2.1: Divide the control stick displacement data into k segments. Starting from the first segment, iterate through all the data. Take the absolute value of the i-th segment and search for the data segment l with a data length greater than 2 seconds and each data point greater than the threshold M. If l exists, it is preliminarily determined that there may be a step control stick action near this segment. Otherwise, jump to the next segment (i+1-th segment) before iterating through the last segment. Step 2.2: Take the control stick displacement data within the first 2 seconds of segment l. Find the last data position P that is greater than the threshold M in this data. Select the control stick displacement data from P to P1 1 second before it and iterate forward. P2 is the position 0.2 seconds before P. When the control stick displacement from P2 to P1 exceeds the threshold D, move both P2 and P forward by one position until all data does not exceed the threshold D. If the condition is still not met when P2 moves to the position of P1, jump to segment i+1 and re-identify and judge. After the above conditions are met, select the control stick displacement data and normal overload data from segment P201 to P2 1 second before P2 to judge the validity of the action. If the control stick displacement data does not exceed the threshold D and the change does not exceed the threshold E and the normal overload data does not exceed the threshold F during this period, then the position P2 can be determined as the starting point of the action of the control stick displacement data in this segment. Otherwise, jump to segment i+1 and re-identify and judge.

[0026] Step 2.3: Select the control stick displacement data from P2 to P21 (1 second later) and iterate backwards. P3 is the position 0.3 seconds after P2. If the control stick data in the segment from P2 to P3 exceeds the threshold D, move both P2 and P3 one position backwards until all data does not exceed the threshold D. If the condition is still not met when P3 moves to the position of P21, jump to segment i+1 and re-identify and judge. After the above conditions are met, it can be determined that the position of P3 is the inflection point of the control stick displacement data action in this segment.

[0027] Step 2.4: Select the data segment from P3 to P38 8 seconds later and traverse it backwards. P32 is the position 2 seconds after P3. If the average value U of the difference between adjacent data in the control stick displacement data segment from P3 to P32 is greater than 0.12, jump to segment i+1 to re-identify and judge. Otherwise, move both P3 and P32 one position backwards until U is greater than 0.12 or P32 moves to P38. After the above conditions are met, it can be determined that the position P32 is the end point of the control stick displacement data action in this segment.

[0028] Step 2.5: After completing the traversal of all k segments, remove duplicate values ​​from the found start and end point arrays, store the processed action positions, and complete the search and extraction of the steady-state maneuvering force action for each g.

[0029] The logic diagram for the search and extraction process is as follows: Picture 4 As shown, the action after truncating is as follows Picture 5 As shown.

[0030] Step 3: Selection and calculation of effective data for steady-state control force per g.

[0031] Step 3.1: In the preprocessed test data, first take the absolute value of the driver's stick force data and calculate the average value, and compare it with the average value calculated after taking the absolute value of the passenger's stick force data. Select the data with the larger average value as the effective driver's stick force data.

[0032] Step 3.2: Select the normal overload data, angle of attack data, and effective control stick force data for the time period 1 second before the start of the action P2, and take their average value as the normal overload before the start of the steady-state control force action per g. Nz s Angle of attack α s and control stick force Fe s .

[0033] Step 3.3: Select the inflection point P3 to the end point P32, with P322 being the position 2 seconds after P3. Simultaneously move P3 and P322 backwards until P322 reaches P32. Calculate the sum of the differential slopes of the overload data, angle of attack data, and effective control stick force from P3 to P322 after each round of movement. Find the steady-state effective data starting points P3' and P322' that have the smallest sum of slopes. Finally, calculate the average of the normal overload data, angle of attack data, and control stick force data between P3' and P322' as the normal overload after the action stabilizes. Nz e Angle of attack α e and control stick force Fe e .

[0034] Step 3.4: Calculate the ratio of overload to angle of attack change and the ratio of overload to rod force change according to the following formulas.

[0035] .

[0036] Step 4: Flight quality evaluation of test data.
