[0002] Spoilers are an important component of modern aircraft flight control systems. The up-deflection suppression function of spoilers is to automatically prevent spoilers from extending or to retract spoilers that have already extended under certain conditions, so as to prevent abnormal aerodynamic characteristics from endangering flight safety. As one of the key control surfaces for aircraft attitude control, spoilers play a vital role in the flight safety and efficiency of aircraft.

[0003] With the development of flight simulation technology, the use of simulation technology to determine the potential dangers and consequences that may be generated or induced when functional failure occurs has been widely applied. By establishing simulation models, studying the flight attitude and emergency response procedures under spoiler suppression has become an important means of aircraft design.

[0004] However, the coupling control is difficult to address when spoiler failure affects the aircraft's three-channel flight attitude, induces aircraft stall, and damages the wing and hinge structures.

It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] In this embodiment of the invention, a simulation method for suppressing deflection on a spoiler plate is provided, such as... Figure 1 As shown, the method includes: Step S101: Determine the deflection polarity of the spoiler, and based on the deflection polarity, obtain the real-time hinge torque of the left spoiler and the right spoiler; Step S102: Determine the deflection direction of the spoiler by the real-time hinge torque of the spoiler, set the deflection speed of the spoiler, input the deflection speed and the deflection direction to the spoiler actuator, and operate the control surface of the spoiler by the spoiler actuator; Step S103: Set the threshold value TH for stopping the deflection of the spoiler. When the absolute value of the real-time hinge torque is less than TH, the spoiler's control surface is stopped from deflecting by the spoiler actuator.

[0015] In specific implementation, the deflection polarity of the spoiler is determined through the following steps, and based on the deflection polarity, the real-time hinge torque of the left and right spoilers is obtained: Based on the characteristic that the aircraft spoilers deflect with the ailerons, the deflection polarity of the spoilers is determined, wherein the upper deflection polarity of the left spoiler is positive and the upper deflection polarity of the right spoiler is negative; the deflection angles of the left and right spoilers are acquired in real time by sensors; a hinge torque database is obtained, and the real-time hinge torques of the left and right spoilers are obtained from the hinge torque database based on the deflection polarity and the deflection angle.

[0016] In specific implementation, the real-time hinge torques of the left and right spoilers are obtained from the hinge torque database based on the deflection polarity and the deflection angle through the following steps: Based on the deflection angle, the hinge torque database is queried to obtain the corresponding reference hinge torque, wherein the hinge torque database is used to define the mapping relationship between the deflection angle and the hinge torque; real-time aerodynamic parameters of the aircraft are obtained, including aileron deflection angle, flap deflection angle, aircraft angle of attack, airspeed, and Mach number; the real-time aerodynamic parameters are input into the aerodynamic correction model, and the hinge torque correction amount for the current flight state is calculated through the aerodynamic correction model; the reference hinge torque and the hinge torque correction amount are fused to generate a first real-time hinge torque estimate; the pressure signals of the two chambers of the spoiler actuator are collected in real time, and the pressure difference between the two chambers is calculated through the pressure signals; based on the set pressure-torque mapping relationship table, the pressure difference is converted into a second real-time hinge torque estimate; the second real-time hinge torque estimate is used to verify and fuse the first real-time hinge torque estimate, and the final real-time hinge torques of the left and right spoilers are output.

[0017] In specific implementation, the following steps are used to determine the deflection direction of the spoiler by the real-time hinge torque of the spoiler, set the deflection speed of the spoiler, and input the deflection speed and the deflection direction to the spoiler actuator: Based on the real-time hinge torque and the deflection polarity, the deflection direction of the spoiler is determined. Specifically, for the left spoiler, when the real-time hinge torque is greater than zero, the control surface cannot deflect upwards; when the real-time hinge torque is less than zero, the control surface deflects downwards. For the right spoiler, when the real-time hinge torque is less than zero, the control surface cannot deflect upwards; when the real-time hinge torque is greater than zero, the control surface deflects downwards. The hydraulic system pressure of the spoiler actuator is obtained, based on a preset speed reflection... Using a velocity mapping table or a velocity function, the actual deflection speed of the spoiler is calculated based on the real-time hinge torque and the hydraulic system pressure. The actual deflection speed is positively correlated with the hydraulic system pressure and negatively correlated with the real-time hinge torque that counteracts the movement of the spoiler actuator. The deflection direction and the actual deflection speed are integrated into an actuator control command, which is then sent to the spoiler actuator to operate the spoiler's control surfaces for deflection.

[0018] In specific implementation, the threshold value TH for stopping the spoiler deflection is set through the following steps: when the absolute value of the real-time hinge torque is less than TH, the spoiler's control surface stops deflecting through the spoiler actuator. The spoiler deflection stop threshold TH is set based on flight state parameters; during spoiler deflection, the absolute value of the spoiler hinge torque is calculated in real time; the absolute value of the spoiler hinge torque is compared with the threshold TH, and when the absolute value of the spoiler hinge torque is less than the threshold TH, a deflection stop control signal is generated; the deflection stop control signal is sent to the spoiler actuator, and the spoiler actuator controls the spoiler control surfaces to stop deflecting.

[0019] In practice, the following steps are used to set the threshold value TH for stopping spoiler deflection based on flight state parameters: The system acquires current flight status parameters in real time, including airspeed, Mach number, angle of attack, and barometric altitude. Based on these parameters, it queries a preset threshold mapping table, which defines the correspondence between different combinations of flight status parameters and recommended threshold values ​​TH. According to the query results, it calculates a dynamic threshold value TH_dynamic applicable to the current flight status and uses this dynamic threshold value TH_dynamic as the threshold value TH.

[0020] In one embodiment of the present invention, such as Figure 2 As shown, this invention proposes a simulation implementation method for suppressing bias on a spoiler plate. The specific implementation steps are as follows: Step 1: Determine the spoiler deflection polarity and calculate the spoiler hinge torque. Based on the characteristic that the spoiler deflects with the aileron, the spoiler deflection polarity should be the same as that of the aileron on the same side. Furthermore, since the spoiler is located on the upper side of the wing, it can only deflect upwards relative to the wing. Therefore, the deflection polarity of the left spoiler is positive, and the deflection polarity of the right spoiler is negative.

[0021] The real-time hinge torque of the left and right spoilers is obtained based on the spoiler deflection angle obtained from the sensor and the hinge torque database obtained from the experiment.

[0022] Specifically, a baseline hinge moment is first obtained from a pre-established hinge moment database, based on a direct measurement of the current control surface deflection angle, using a database established through wind tunnel or flight testing. This forms the basis for the estimation. However, the aircraft's aerodynamic environment is dynamic. Therefore, the scheme incorporates real-time aerodynamic parameters (such as aileron and flap positions, angle of attack, and airspeed) and calculates the hinge moment correction using an aerodynamic correction model. This model is essentially a real-time aerodynamic calculator used to compensate for changes in the current flight state not considered when querying the database. Finally, by fusing the baseline value with the correction, a first real-time hinge moment estimate is generated—a more accurate estimate calibrated for the aerodynamic environment in real time.

[0023] Then, the physical signals are directly measured and redundancy checks are performed. To further improve reliability and address sensor failures, the solution introduces a completely independent, physics-based measurement channel. By acquiring the pressure signals from the two chambers of the spoiler actuator and calculating the pressure difference, the actual load that the drive surface needs to overcome is directly reflected.

[0024] Based on a pre-defined pressure-torque mapping table (obtained through actuator ground test bench experiments), the physical pressure signal is converted into a second real-time hinge torque estimate. This value is independent of aerodynamic models and angle sensors, providing a direct physical measurement reference.

[0025] Finally, data fusion and final decision-making are performed. Estimates from two different technical approaches (aerodynamic calculation approach and physical measurement approach) are verified and fused.

[0026] Data fusion can employ various algorithms, such as weighted averaging (when both are reliable) or selecting the more reliable one (when one exhibits a significant anomaly, such as sensor failure). The final output is the real-time hinge torque, which offers higher accuracy, reliability, and fault tolerance compared to any single data source.

[0027] A dual-redundancy architecture for aerodynamic model estimation and physical signal measurement was constructed. When the angle sensor fails or the aerodynamic model exhibits large errors under extreme conditions, the pressure signal provides a reliable backup calculation channel, ensuring that the simulation system can still provide reasonable torque estimates even in the "failure" mode of some components, thus avoiding simulation distortion or interruption caused by the failure of a single data source.

[0028] The hinge torque is the core input for controlling the deflection of the control surfaces and judging the suppression logic. The improvement of its calculation accuracy directly makes the simulation test results of the "spoiler deflection suppression" function more reliable, thus providing a more solid data foundation for evaluating the safety boundary of this function in actual flight.

[0029] Step 2: Determine the deflection direction and deflection speed of the spoiler.

[0030] When the hinge torque is positive, the rudder deflects in the positive direction; when the hinge torque is negative, the rudder deflects in the negative direction. Since the spoiler cannot deflect upwards due to an upward deflection suppression fault, based on the spoiler deflection polarity and hinge torque obtained in step one, for the left spoiler, when the hinge torque is greater than 0, the rudder cannot deflect; when the hinge torque is less than 0, the rudder deflects downwards. For the right spoiler, when the hinge torque is less than 0, the rudder cannot deflect; when the hinge torque is greater than 0, the rudder deflects downwards.

[0031] When the control surface deflects, it deflects at the maximum capacity of the spoiler actuator.

[0032] Introducing a health status parameter as a comprehensive indicator into the simulation is used to quantify the degree of performance degradation of the simulated actuator, such as simulating efficiency reduction caused by hydraulic leakage or increased friction caused by mechanical wear.

[0033] Based on the hydraulic system pressure (representing available power) and health status parameters (representing system efficiency), the current maximum theoretical output capacity is calculated. This means that the maximum capacity of the simulated actuator is not a fixed value, but rather changes dynamically with the virtual health status and system pressure, consistent with the characteristics of a real physical system.

[0034] A velocity mapping relationship is defined to characterize the nonlinear proportional relationship between the actual deflection speed and the current maximum theoretical output capability when an aerodynamic load (i.e., real-time hinge torque) counteracts the actuator's motion. The core characteristic of a real actuator—the greater the load, the slower the speed—is simulated. When the hinge torque counteracts the motion, a portion of the actuator's output capability needs to be used to overcome this aerodynamic load, resulting in a decrease in the effective capability for driving the control surface deflection. Consequently, the actual deflection speed will be less than or equal to the theoretical maximum capability according to the predetermined mapping relationship. The velocity decay or slippage phenomenon of the actuator under load is accurately simulated.

[0035] A logic was implemented to set the actual deflection speed to zero when the direction of the real-time hinge torque is the same as the deflection direction, simulating the physical nature of the "upward deflection suppression" fault. When the aerodynamic load (hinge torque) attempts to push the control surface in the required deflection direction (i.e., upward deflection), and the actuator, due to a fault, cannot provide sufficient force to overcome this load and moves in the opposite direction (i.e., downward deflection), the control surface is effectively "locked" in its current position by aerodynamic forces. Forcing the speed to zero in this scenario, rather than simply stopping the actuation, is a highly accurate mathematical description of this physical process, ensuring the realism of the simulation model under critical fault transients.

[0036] Step 3: Set the logic for stopping the spoiler deflection.

[0037] Set a threshold value TH for the spoiler to stop deflecting. When the absolute value of the spoiler hinge torque is less than TH, the spoiler stops deflecting.

[0038] The threshold value TH can be set to a fixed value. However, in typical real-world environments, the threshold value TH is affected by current flight parameters. Therefore, TH can be calculated in real time or obtained from a table based on flight parameters (such as airspeed, Mach number, angle of attack, and pressure altitude). At high speeds, aerodynamic loads are large, and hinge torque fluctuations are also large, which may require a higher TH to avoid false triggering. The opposite is true at low speeds.

[0039] Starting with real-time flight parameters, a baseline value is obtained by querying a preset mapping table, and finally the dynamic threshold used in the current simulation is calculated and set.

[0040] Specifically, by setting the actual deflection speed to zero, the system simulated the suppression state where the spoiler could not overcome the aerodynamic load and deflected upwards.

[0041] In this embodiment, a computer device is provided, such as... Figure 3 As shown, it includes a memory 301, a processor 302, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the above-mentioned simulation method for suppressing the deflection of the spoiler plate.

[0042] Specifically, the computer device can be a computer terminal, a server, or a similar computing device.

[0050] In one embodiment, the spoiler deflection module includes: A deflection direction determination unit is used to determine the deflection direction of the spoiler based on the real-time hinge torque and the deflection polarity. Specifically, for the left spoiler, when the real-time hinge torque is greater than zero, it is determined that the control surface cannot deflect upward, and when the real-time hinge torque is less than zero, it is determined that the control surface deflects downward. For the right spoiler, when the real-time hinge torque is less than zero, it is determined that the control surface cannot deflect upward, and when the real-time hinge torque is greater than zero, it is determined that the control surface deflects downward. The actual deflection speed calculation unit is used to obtain the hydraulic system pressure of the spoiler actuator, and calculate the actual deflection speed of the spoiler based on a preset speed mapping function or speed mapping table, according to the real-time hinge torque and the hydraulic system pressure. The actual deflection speed is positively correlated with the hydraulic system pressure and negatively correlated with the real-time hinge torque that resists the movement of the spoiler actuator. An operation deflection unit is used to integrate the deflection direction and the actual deflection speed into an actuator control command, and send the actuator control command to the spoiler actuator to operate the spoiler's control surface for deflection via the spoiler actuator.

[0052] The embodiments of the present invention achieve the following technical effects: To address the challenges of spoiler failures affecting aircraft's three-channel flight attitude, inducing stall, and causing damage to wing and hinge structures, as well as the difficulty of coupled control, a simulation method for spoiler bias suppression was designed. This method can be used for theoretical simulation of spoiler failures. By introducing real-time aerodynamic corrections, the calculation of hinge torques can dynamically respond to complex flight state changes, overcoming the limitations of static databases and significantly improving the consistency between the simulation model and the real physical world. Furthermore, by introducing health state parameters, the simulation of slow performance degradation or sudden failure of the actuators themselves was implemented within this simulation framework. This is crucial for studying the robustness of flight control systems under incomplete failure but performance degradation failure modes, covering a wider range of fault safety assessment scenarios.

When the absolute value of the real-time hinge torque is less than TH, the spoiler's control surface is stopped from deflecting by the spoiler actuator.
