Description

Technical Field

[0001] The invention belongs to the technical field of civil cockpit design in the aviation field, and in particular relates to a flap handle device supporting automatic control and a control method. Background Art

[0002] The flap is a movable device on the wing of an aircraft, mainly installed on the trailing edge or leading edge of the wing. It can change the shape of the wing by deflecting or sliding downward, thereby affecting the lift and drag of the aircraft. The flap is a kind of aircraft lift-enhancing device. During the take-off and landing phase of the aircraft, the pilot lowers the flap through the flap control system to achieve the purpose of short-distance take-off and landing. The flap control system is mainly composed of the flap control handle, flap control box, and flap electric mechanism.

[0003] Currently, the flap handle in the flap control system is in passive mode, that is, the handle position angle is used as the driving signal, so flap configuration control cannot be completed during automatic flight. In addition, the flap position is inconsistent with the handle position during the power-on stage of the aircraft, which can easily cause injury to maintenance personnel. Summary of the invention

[0038] The automatic configuration mode switching switch is arranged on the top of the handle; the automatic configuration mode switching switch is used to switch the flap configuration;

[0039] The sleeve is sleeved on the handle 4;

[0040] The position limiter 6 shown includes a plurality of position limiting slots; the position limiting slots are used for positioning the handle;

[0041] The bottom of the handle 4 is connected to the position limiter 6;

[0042] The sensor 5 is provided at the bottom of the handle 4; the sensor 5 is used to measure the handle position angle and obtain the handle position angle signal;

[0043] The bottom of the position limiter 6 is mounted on the motor 7; the motor 7 is used to drive the position limiter 6 to rotate, thereby changing the flap configuration;

[0044] The sleeve 2 is moved, and the handle 4 is fixed in the position of the limiting slot by the buckle between the sleeve 2 and the limiting slot.

[0045] Furthermore, a positioning mark 3 is provided above the positioning limiter, and the positioning mark 3 is used for flap configuration identification.

[0046] Furthermore, the sensor 5 transmits the position signal of the handle 4 to the high lift computer and converts it into a driving signal for flap actuation, thereby driving the flap actuation.

[0047] Furthermore, the number of the limit slots is determined according to the number of flap configurations. If the number of flap configurations is N, the number of the limit slots is (3N-2). Figure 1 As shown in the figure, there are 5 flap configurations, and the flap configuration identifications are: 0, 1, 2, 3 and FULL, and the number of limit slots is 13. The limit slots in the figure include: A, B, C, D, E, F, G, H, I, J, K, L and M.

[0048] Furthermore, the motor receives a flap configuration change instruction from the automatic flight system, drives the position limiter 6 and the handle 4 to rotate together, thereby changing the flap configuration.

[0049] Furthermore, when the sleeve 2 is lifted, the sleeve 2 and the limiting slot are unlocked, and the limit of the handle 4 in the limiting slot is released; when the sleeve 2 is put down, the sleeve 2 and the limiting slot are locked, and the handle 4 is locked in the limit position.

[0050] A control method for the above device, the control method comprising three control modes: a manual control mode, an automatic control mode and a power-on mode;

[0051] The manual control mode and the automatic control mode are switched by pressing the automatic configuration mode switch; after the aircraft is powered off and then powered on again, it automatically enters the power-on mode, and when the handle position is consistent with the control surface position, the power-on mode is exited.

[0052] Furthermore, the manual control mode includes: lifting the sleeve, the handle is released from the limit position in the limit slot, moving the handle to the selected slot, lowering the sleeve, and the handle is locked in the selected slot position to achieve the adjustment control of the flap configuration.

[0055] The high-lift computer verifies whether the handle position is consistent with the rudder surface position. If the handle position is consistent with the rudder surface position, the power-on mode is exited and the manual control mode is entered. If the handle position is inconsistent with the rudder surface position, the high-lift computer sends a drive instruction to drive the motor according to the position of the rudder surface. The motor drives the position limiter to rotate, and the position limiter drives the handle to rotate to the position corresponding to the current rudder surface position, and the power-on mode is exited and the manual control mode is entered. Figure 6 shown.

[0056] Example 2

[0057] A flap handle device supporting automatic control, the flap handle device comprising: an automatic configuration mode switching switch 1, a sleeve 2, a position mark 3, a handle 4, a sensor 5, a position limiter 6 and a motor 7; Figure 1 shown.

[0058] The automatic configuration mode switch is installed on the top of the handle. The pilot can switch the flap configuration by pressing the automatic configuration mode switch.

[0059] The sleeve is a handle limiter installed on the handle, and together with the position limiter, ensures that the handle position angle remains unchanged. When not in operation, when the sleeve is in the lowered position, the sleeve can ensure that the relative position of the handle and the position limiter remains unchanged.

[0060] The sensor is located at the bottom of the handle and is used to measure the handle position angle. The flap handle sensor transmits the handle position signal to the high lift computer and converts it into a flap actuation drive signal to drive the flap actuation.

[0061] The position mark is relatively independent from the handle and the position limiter. It is used by the pilot to identify the current flap configuration. Figure 1 As shown in FIG. 1 , the five configurations of the card position mark are marked as: 0, 1, 2, 3 and FULL. Figure 1 shown.

[0062] The bottom of the stop limiter is installed on the motor, which can receive the flap configuration change command from the automatic flight system, drive the stop limiter and the handle to rotate together, and then change the flap configuration. Figure 1 As shown, the card position limiter includes 13 card slots, namely A, B, C, D, E, F, G, H, I, J, K, L, and M. Figure 1 shown.

[0063] A flap handle and control method supporting automatic control mainly include three control modes: manual control mode, automatic control mode and power-on mode; the handle position angle is the only instruction to drive the flap actuation, and the pilot can switch between manual control mode and automatic control mode by pressing the automatic configuration mode switching switch set on the handle.

[0064] The automatic configuration mode switch can provide a light indication to remind the pilot of the configuration control status. In the automatic control mode, the AUTO (green) light is on, and in the manual control mode, the AUTO (green) light is off.

[0065] When the aircraft is powered off and then powered on again, the control mode automatically enters the power-on mode. When the handle position mark position is consistent with the control surface position, the power-on mode is exited.

[0066] After entering the power-on mode, the AUTO (red) light turns on. After exiting the power-on mode, the AUTO (red) light turns off.

[0067] In manual control mode, Figure 2 , 3 As shown, the pilot needs to manually lift the sleeve, manually release the limit lock of the sleeve, move the handle to the target position, the relative position of the handle and the position limiter changes, and then lower the sleeve to limit the handle. As shown in the figure, move the handle from the E slot to the F slot. At this time, the flap configuration also changes from the 0 position to the 1 position configuration.

[0068] Automatic control mode, such as Figure 4 , 5 As shown, the pilot sets the control mode to the automatic control mode. In the automatic control mode, the AUTO (green) light is on, prompting the pilot to be in the automatic control mode.

[0069] At this time, the flap configuration is controlled by the automatic flight system. When the automatic flight system issues a flap configuration change control command, the motor drives the position limiter to rotate, and the position limiter drives the handle to rotate together, rotate to the target position, and then the handle position angle is used as the output to drive the flap actuation.

[0070] like Figure 4 As shown in the figure, when the automatic flight system issues a flap configuration change control command, the command flap configuration changes from 0 position to 1 position, the motor receives the change command and drives the position limiter to rotate. At this time, the sleeve is in the lowered position, under which the relative position of the position limiter and the handle is locked unchanged, the handle is always in the E slot, the position limiter rotates under the drive of the motor, driving the handle to rotate together, so that the flap configuration pointed by the handle also changes, from 0 position to 1 position configuration, and then the current flap handle position angle is used as the output to drive the flap actuation.

[0071] The power-on mode provides a solution to the inconsistency between the handle and the control surface. Figure 6 shown.

[0072] When the aircraft is powered on again after a power outage, the handle automatically enters the power-on mode. At this time, the AUTO (red) light comes on, and the high lift computer checks the handle position and the control surface position obtained. If the handle position is consistent with the control surface position, the AUTO (red) light goes out to exit the power-on mode, and the flap handle is set to manual control mode.

[0073] If the handle position is inconsistent with the rudder position, the high lift computer sends a drive command to the motor according to the current position of the rudder, and the motor receives the change command and drives the position limiter to rotate. Under its action, the relative position of the position limiter and the handle remains unchanged, and the handle is rotated to the position matching the rudder position.

[0074] The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
