Description

Technical Field

[0001] The invention relates to the field of reverse thrust devices of aircraft engines, and in particular to a test fixture for follow-up loading of a baffle mechanism of a reverse thrust device. Background Art

[0002] The thrust reverser is an important component of the nacelle of large transport aircraft and large passenger aircraft. Its main function is to obtain reverse thrust by changing the direction of the engine exhaust flow, so as to decelerate the aircraft efficiently and reliably, significantly shorten the landing and roll distance of the aircraft, reduce the aircraft's requirements for the airport, and improve the efficiency of airport use. It can also be used for aircraft aborted takeoffs to improve the safety of aircraft operations.

[0003] At present, the thrust reverser widely used in high bypass ratio turbofan aircraft engines is the cascade thrust reverser, which includes the C-type cascade thrust reverser and the O-type cascade thrust reverser. Figures 1 - 9 , taking the C-type cascade thrust reverser 100 as an example for introduction. The C-type cascade thrust reverser 100 is composed of a left half C-type culvert 101 and a right half C-type culvert 102 with the same functions and similar structures. The left half C-type culvert 101 and the right half C-type culvert 102 are respectively composed of two components, a fixed structure 110 and a movable outer cover 120, wherein the fixed structure 110 includes an upper slide rail beam 111, a lower slide rail beam 112, a torque box 113, a core nacelle cover 114 and a cascade 115, and the movable outer cover 120 includes an upper slide rail 121, a lower slide rail 122, an outer wall plate 123, an outer culvert outer wall 124, 5 blocker doors 125 and 5 pull rods 126.

[0004] When the reverse thrust is working, the H-TRAS drives the mobile cover 120, and the upper slide rail 121 and the lower slide rail 122 of the mobile cover 120 move backward together in the slide rail groove 116 of the upper slide rail beam 111 and the slide rail groove 116 of the lower slide rail beam 112. The front end support of the outer wall 124 of the outer culvert drives the front end support of the five blocker doors 125 to move horizontally. At the same time, the five blocker doors 125 are deflected under the action of the five pull rods 126, and finally block the reverse thrust outer duct airflow. The outer duct airflow is deflected by the blocker door 125 and discharged obliquely forward through the cascade 115, thereby generating reverse thrust. Among them, a single blocker door 125, the relevant support on the blocker door 125 and the corresponding pull rod 126 constitute a single set of blocker door mechanisms, and the movement law of each set of blocker door mechanisms is completely consistent.

[0005] During the normal deployment and retraction of the reverse thrust device of an aircraft engine, the baffle in the reverse thrust device will move and rotate accordingly with the backward or forward movement of the movable outer cover, while carrying aerodynamic loads with different airflow intensities.

[0006] Before the thrust reverser is installed on the engine for the ground test of the whole machine, it is necessary to conduct a ground test of the thrust reverser alone. One of the important contents of the ground test of the thrust reverser is the deployment and retraction test of the thrust reverser, which detects the performance of the thrust reverser under the pneumatic loads of different airflow intensities during the movement of the blocker door along with the movable cowl, that is, the performance under follow-up loading.

[0007] Before the newly developed blocker door mechanism is integrated into the thrust reverser, if it has not been tested and verified separately, when the blocker door mechanism is tested along with the thrust reverser components, the test may fail due to the unreasonable design of the blocker door mechanism. Therefore, before the blocker door mechanism is integrated into the thrust reverser, it is necessary to conduct a component-level mechanism test specifically for the newly developed blocker door mechanism to eliminate design defects as early as possible, so as to ensure that the blocker door mechanism can be deployed and retracted normally during the test of the thrust reverser. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the defect that when the blocker door mechanism is tested along with the thrust reverser components in the prior art, the test may fail due to the unreasonable design of the blocker door mechanism, and to provide a test tool for follow-up loading of the blocker door mechanism.

[0009] The present invention solves the above technical problem through the following technical solutions:

[0010] A test tool for follow-up loading of a blocker door mechanism, which is used to detect the reliability of the blocker door mechanism under pneumatic loads. The test tool is characterized in that it includes a first driving component, a loading component and a guiding mechanism. The first driving component is movably connected to the loading component, the loading component is movably connected to the front surface of the blocker door of the blocker door mechanism, and the guiding mechanism is movably connected to the loading component;

[0011] When the blocker door mechanism conducts a follow-up loading test, the first driving component cooperates with the guiding mechanism to keep the loading component perpendicular to the blocker door, and the loading component loads the simulated load onto the blocker door.

[0012] In this solution, the test tool includes a first driving component, a loading component and a guiding mechanism. During the process of the blocker door mechanism moving and rotating forward and backward along with the movable cowl, the first driving component and the guiding mechanism cooperate to guide and push the loading component to adjust its position and direction, so that the loading component is perpendicular to the blocker door. At the same time, the loading component applies a force to the blocker door, so as to ensure that during the movement of the blocker door, the force applied by the test tool to the blocker door is always perpendicular to the blocker door and the magnitude of the force can be adjusted, thereby simulating the pneumatic load situation borne by the front surface of the blocker door during the actual movement of the blocker door mechanism and detecting the reliability of the blocker door mechanism under pneumatic loads.

[0013] Preferably, the guiding mechanism includes a guiding plate, a guiding groove is provided on the guiding plate, the loading assembly includes a sliding member, the sliding member is arranged at a position corresponding to the guiding groove of the loading assembly, and the sliding member slides along the guiding groove.

[0014] In this solution, by arranging a guiding groove in the guiding mechanism, arranging a sliding member in the loading assembly, and setting the sliding member to slide along the guiding groove, during the movement of the choke valve mechanism, through the relative sliding between the guiding groove and the sliding member, the guiding mechanism in the test tooling provides support and guiding effects in a specific direction and position for the loading assembly. In cooperation with the acting force provided by the first driving assembly on the loading assembly, the loading assembly is kept perpendicular to the choke valve, ensuring that the acting force applied by the test tooling is always perpendicular to the choke valve, and simulating the situation of the pneumatic load borne by the choke valve during movement.

[0015] Preferably, the guiding groove penetrates through the guiding plate along the thickness direction of the guiding plate, and the sliding member is arranged in the guiding groove.

[0016] In this solution, by setting the guiding groove to penetrate through the guiding plate and arranging the sliding member in the guiding groove, the sliding member is more smoothly connected to the guiding groove and slides along the guiding groove, enabling the guiding plate to more smoothly support and guide the movement of the loading assembly, and keeping the loading assembly perpendicular to the choke valve.

[0017] Preferably, the loading assembly further includes a rolling member, the rolling member is fixedly connected to the end of the sliding member, and the rolling member rolls in the guiding groove along with the sliding member.

[0018] In this solution, by fixedly connecting a rolling member to the end of the sliding member and arranging the rolling member to roll in the guiding groove, a smoother relative sliding between the sliding member and the guiding groove is achieved, reducing the frictional resistance of the relative movement between the guiding plate and the loading assembly, and better realizing that during the movement of the choke valve, by adjusting the position and direction of the loading assembly, the loading assembly is kept perpendicular to the choke valve.

[0019] Preferably, the guiding mechanism includes a first actuating cylinder, the first actuating cylinder is movably connected to the loading assembly, and the connection position of the first actuating cylinder and the loading assembly is located at a position of the loading assembly away from the first driving assembly.

[0020] In this solution, by arranging a first actuating cylinder in the test tooling, movably connecting the first actuating cylinder to the loading assembly, and the connection position of the first actuating cylinder and the loading assembly is located at a position of the loading assembly away from the first driving assembly, through the combined action of the first driving assembly and the first actuating cylinder on the loading assembly, the loading assembly is supported and guided to be perpendicular to the choke valve during the movement of the choke valve.

[0021] Preferably, the first driving assembly includes a second actuating cylinder, a first guide rail, and a first slider. The first slider is slidably connected to the first guide rail. The second actuating cylinder is connected to the first slider, and the first slider is movably connected to the loading assembly.

[0022] In this solution, a second actuating cylinder, a first guide rail, and a first slider are provided in the first driving assembly. Under the control of the second actuating cylinder, the first slider moves on the first guide rail, thereby driving the adjustment of the position and direction of the loading assembly. With the cooperation of the guiding mechanism, the loading assembly is kept perpendicular to the choke valve during the movement of the choke valve.

[0023] Preferably, the loading assembly includes a third actuating cylinder and a support. One end of the third actuating cylinder is movably connected to the choke valve, the other end of the third actuating cylinder is fixedly connected to the support, and the support is movably connected to the first driving assembly.

[0024] In this solution, by providing a third actuating cylinder and a support in the loading assembly and connecting the support to the first driving assembly, the third actuating cylinder in the loading assembly can adjust the position and direction in real time under the combined action of the first driving assembly and the guiding mechanism during the movement of the choke valve, so as to be perpendicular to the choke valve and apply a force to the choke valve to simulate the load.

[0025] Preferably, the third actuating cylinder is perpendicular to the support.

[0026] In this solution, the third actuating cylinder is arranged perpendicular to the support, making the adjustment of the position and direction of the third actuating cylinder by the first driving assembly more sensitive and facilitating the loading assembly to be perpendicular to the choke valve.

[0027] Preferably, there are a plurality of the third actuating cylinders, and the plurality of third actuating cylinders are arranged in parallel. The connection positions of the third actuating cylinders and the choke valve are evenly arranged on the choke valve.

[0028] In this solution, by providing a plurality of third actuating cylinders in the loading assembly and connecting them in parallel and evenly to the choke valve, the load applied by the loading assembly to the choke valve is more evenly symmetric, better simulating the actual aerodynamic load situation on the choke valve.

[0029] Preferably, the test tooling further includes a second driving assembly, which is movably connected to the back of the choke valve and is used to drive the movement of the choke valve to simulate the unfolding and retracting processes of the choke valve mechanism.

[0030] In this solution, by setting a second driving component in the test tooling, the second driving component drives the baffle door to move to simulate the normal deployment and retraction processes of the baffle door mechanism. During the simulation of the deployment and retraction processes of the baffle door mechanism by the test tooling, a simulated load is applied through the loading component to detect the reliability of the baffle door mechanism during movement.

[0031] Preferably, the second driving component includes a second guide rail, a second slider, and a fourth actuator. The second slider is slidably connected to the second guide rail. The fourth actuator is connected to the second slider, and the second slider is movably connected to the back of the baffle door.

[0032] In this solution, by setting a second guide rail, a second slider, and a fourth actuator, the fourth actuator is used to control the movement of the second slider on the second guide rail, thereby adjusting the position and direction of the baffle door over time to simulate the normal deployment and retraction processes of the baffle door mechanism and detect the reliability of the baffle door mechanism during movement.

[0033] Preferably, the test tooling further includes a frame disposed around the first driving component, the loading component, and the guiding mechanism for supporting or fixing the first driving component, the loading component, and the guiding mechanism.

[0034] In this solution, by setting a frame in the test tooling to support or fix the first driving component, the loading component, and the guiding mechanism, a reliable peripheral support is provided for detecting the baffle door mechanism, ensuring the accuracy of the detection test.

[0035] The positive and progressive effects of the present invention are as follows: By setting a first driving component, a loading component, and a guiding mechanism in the test tooling, during the follow-up loading test of the baffle door mechanism, the first driving component and the guiding mechanism form a resultant force acting on the baffle door to cooperate with the movement of the baffle door mechanism, keeping the loading component perpendicular to the baffle door. At the same time, a simulated load is applied to the baffle door through the loading component, thereby accurately simulating the situation where the aerodynamic load is applied to the baffle door during the movement of the baffle door mechanism and detecting the reliability of the baffle door mechanism under the aerodynamic load.

[0092]

Embodiment 1

[0093] As Figures 10 - 18As shown in the figure, Embodiment 1 of the present invention provides a test tooling for the follow-up loading of a choke valve mechanism. The test tooling is movably connected to the choke valve mechanism, and the test tooling applies different loads to the front surface of the choke valve 10, so as to simulate the loads of different air flow intensities borne by the choke valve 10 during movement. During the real-time movement of the choke valve 10, the test tooling applies the simulated load to the choke valve 10 in the vertical direction with different pressure intensities, that is, applies the load vertically to the choke valve 10 in a follow-up loading manner to test the reliability of the choke valve mechanism during the deployment and retraction of the thrust reverser. Specifically, the test tooling includes a first driving component, a loading component, and a guiding mechanism. The first driving component provides a force to the loading component from one end of the test tooling through hydraulic, electric, mechanical, or other driving control methods that can be conceived by those skilled in the art. The first driving component and the loading component are connected through a hinge connection or other movable connection methods that can be conceived by those skilled in the art. The guiding mechanism and the loading component are connected through a hinge connection, a sliding connection, or other movable connection methods that can be conceived by those skilled in the art. The guiding mechanism can also provide a force to the loading component through hydraulic, electric, mechanical, or other driving control methods that can be conceived by those skilled in the art. That is, the guiding mechanism and the first driving component form a resultant force acting on the loading component. During the real-time translational and rotational movements of the choke valve 10, this resultant force pushes the loading component to remain perpendicular to the front surface of the choke valve 10. At the same time, during the real-time translational and rotational movements of the choke valve 10, the loading component provides a vertical pressure or load to the front surface of the choke valve 10 through hydraulic, electric, mechanical, or other driving control methods that can be conceived by those skilled in the art, so as to simulate the aerodynamic load borne by the choke valve 10 during the actual movement process, and further independently detect the reliable performance of the choke valve mechanism at different positions, different rotation angles, and different loads during the movement process.

[0094] Furthermore, the test tooling may further include a frame 99 for supporting or fixing other components or mechanisms in the test tooling except the frame 99, including but not limited to the first driving component, the loading component, and the guiding mechanism, providing a reliable peripheral support for detecting the choke valve mechanism and ensuring the accuracy of the detection test. As Figure 10 、 Figure 11 and Figure 14 shown, the frame 99 is connected to the first driving component, the loading component, the guiding mechanism, or other components or mechanisms of the test tooling through a fixed connection or a hinge connection.

[0095] As Figures 10 - 18As shown, in Embodiment 1, the guiding mechanism in the test tooling for the follow-up loading of the flow blocking door mechanism includes a guiding guide plate 31. The guiding guide plate 31 is arranged on both sides of the loading component, which is beneficial to maintaining the balance and stability of the overall test tooling when supporting and guiding the loading component. The guiding guide plate 31 is provided with guiding grooves 32 with a certain orientation. The loading component includes a sliding member 41. The sliding member 41 is arranged at a position corresponding to the guiding groove 32 of the loading component. The sliding member 41 slides along the guiding groove 32. The connection between the loading component and the guiding mechanism is realized through the sliding connection of the sliding member 41 in the guiding groove 32. The sliding member 41 is a rod-shaped object in this embodiment. In other embodiments, it can also be a bump with a certain shape or other implementation manners that can be conceived by those skilled in the art.

[0096] By setting the guiding guide plate 31 and the guiding groove 32, during the movement of the flow blocking door mechanism, the guiding mechanism in the test tooling provides support and guiding effects in a specific direction and position for the loading component. In cooperation with the force exerted by the first driving component on the loading component, the loading component is kept perpendicular to the flow blocking door 10, ensuring that the force applied by the test tooling is always perpendicular to the flow blocking door 10, simulating the situation of the pneumatic load borne by the flow blocking door 10 during movement.

[0097] Furthermore, the position of the sliding member 41 in the loading component is at a position away from the first driving component of the loading component, so that the guiding guide plate 31 can give a larger lever arm to the loading component through the sliding member 41, thereby enabling the test tooling to more easily guide and adjust the position and direction of the loading component through the guiding mechanism, and keeping the loading component perpendicular to the flow blocking door 10.

[0098] In this embodiment, the trajectory orientation of the guiding groove 32 on the guiding mechanism is obtained by comprehensive calculation of factors such as the unfolding and retracting processes of the flow blocking door 10, the shape and length of the loading component, the force and driving process of the first driving component on the loading component, the connection position of the first driving component and the loading component, and the connection position of the guiding mechanism and the loading component.

[0099] Furthermore, as Figure 12 shown, the guiding groove 32 in the test tooling penetrates the guiding guide plate 31 along the thickness direction of the guiding guide plate 31. The sliding member 41 is inserted into the guiding groove 32, so that when sliding, the sliding member 41 can completely pass through the guiding guide plate 31 and slide, strengthening the stable connection between the sliding member 41 and the guiding groove 32, and enabling the guiding guide plate 31 to more stably support and guide the movement of the loading component.

[0100] Further, the loading component of the test tooling further includes a rolling member 42. The rolling member 42 is fixedly connected to the end of the sliding member 41 and rolls in the guiding groove 32 along with the sliding member 41 without coming out. In this embodiment, the rolling member 42 is a rolling bearing. In other embodiments, the rolling member 42 may also be other structural members that can be conceived by those skilled in the art, so as to achieve a smoother relative sliding between the sliding member 41 and the guiding groove 32, reduce the frictional resistance of the relative movement between the guiding plate 31 and the loading component, and better realize that during the movement of the flow blocking door 10, by adjusting the position and direction of the loading component, the loading component is kept perpendicular to the flow blocking door 10.

[0101] The first driving component in the test tooling includes a second actuating cylinder 1, a first guide rail 6 and a first slider 7. As Figure 15 shown, the first slider 7 is slidably connected to the first guide rail 6. The second actuating cylinder 1 is connected to the first slider 7. Therefore, by the acting force of the second actuating cylinder 1, the first slider 7 can be driven to slide along the first guide rail 6. The first slider 7 is hingedly connected to the loading component. In other embodiments, the connection manner between the first slider 7 and the loading component may also be other movable connection manners that can be conceived by those skilled in the art, so as to realize that the first driving component controls the acting force on the loading component, guides and adjusts the position and direction of the loading component, and further, with the cooperation of the guiding mechanism, the loading component is kept perpendicular to the flow blocking door 10 during the movement of the flow blocking door 10.

[0102] The loading component includes a third actuating cylinder 2 and a support 4. One end of the third actuating cylinder 2 is hingedly connected to the flow blocking door 10. In other embodiments, it may also be other movable connection manners that can be conceived by those skilled in the art, so as to realize the follow-up loading of the third actuating cylinder 2 on the flow blocking door 10 during the movement of the flow blocking door 10, and at the same time, the third actuating cylinder 2 is kept perpendicular to the flow blocking door 10. Under the combined action of the first driving component and the guiding mechanism, the third actuating cylinder 2 in the loading component adjusts the position and direction in real time during the movement of the flow blocking door 10, is kept perpendicular to the flow blocking door 10, and applies an acting force to the flow blocking door 10 to simulate a load. The other end of the third actuating cylinder 2 is fixedly connected to the support 4. The third actuating cylinder 2 and the support 4 are connected at an angle. Preferably, the third actuating cylinder 2 and the support 4 are perpendicularly connected. In this embodiment, setting the third actuating cylinder perpendicular to the support makes the adjustment of the position and direction of the third actuating cylinder by the first driving component more sensitive and facilitates keeping the loading component perpendicular to the flow blocking door. Of course, in other embodiments, the third actuating cylinder 2 and the support 4 may also be connected at a non-angled manner. The support 4 is connected to the first driving component by a hinge connection or other movable connection manners. The fixed connection position of the third actuating cylinder 2 and the support 4 at a reasonable position on the support 4 is beneficial to the adjustment of the position and direction of the third actuating cylinder 2 by the first driving component and facilitates keeping the loading component perpendicular to the flow blocking door 10.

[0103] Similarly, the connection position of the first driving component and the support 4 at a reasonable position on the support 4 is conducive to the first driving component adjusting the position and direction of the third actuator 2, facilitating the perpendicularity between the loading component and the choke valve 10.

[0104] In this embodiment, there are two third actuators 2. In other embodiments, the number of the third actuators 2 can also be three or more. The multiple third actuators 2 are arranged in parallel with each other, and the connection positions of the third actuators 2 and the choke valve 10 are evenly distributed on the choke valve 10, so that the load applied by the loading component to the choke valve 10 is more evenly symmetrical, better simulating the actual aerodynamic load situation applied on the choke valve 10.

[0105] The test tooling may further include a second driving component, which is hingedly connected to the back of the choke valve 10 and is used to drive the choke valve 10 to move to simulate the deployment and retraction processes of the choke valve mechanism. Thus, during the simulated deployment and retraction processes of the choke valve mechanism by the test tooling, the simulated load is loaded through the loading component to detect the reliability of the choke valve mechanism during the movement process. In other embodiments, the connection between the second driving component and the back of the choke valve 10 can also be other movable connection methods conceivable by those skilled in the art.

[0106] Further, the second driving component in the test tooling includes a second guide rail 8, a second slider 9, and a fourth actuator 5. As Figure 16 shown, the second slider 9 is slidably connected to the second guide rail 8, and the fourth actuator 5 is connected to the second slider 9. The test tooling drives the second slider 9 to slide along the second guide rail 8 through the acting force of the fourth actuator 5. As Figure 13 、 Figure 18 shown, the second slider 9 is hingedly connected to the back of the choke valve 10. In other embodiments, it can also be other movable connection methods conceivable by those skilled in the art. By using the fourth actuator 5 to control the movement of the second slider 9 on the second guide rail 8 and under the combined action with the pull rod 11, the position and direction of the choke valve 10 are adjusted to simulate the normal deployment and retraction processes of the choke valve mechanism, and the reliability of the choke valve mechanism during the movement process is detected. As Figure 17 shown, one end of the pull rod 11 away from the choke valve 10 is arranged on the frame 99 simulating the internal fixed structure of the aeroengine.

[0107]

Embodiment 2

[0108] As Figure 19 and Figure 20As shown, Embodiment 2 discloses a specific implementation manner of another test tool for following and loading a choke valve mechanism. The structure of Embodiment 2 is basically the same as that of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the guiding mechanism of the test tool for following and loading the choke valve mechanism in Embodiment 2 includes a first actuator 33, and the first actuator 33 is hingedly connected to the loading assembly. In other embodiments, the connection manner between the first actuator 33 and the loading assembly can also be other movable connection manners conceivable by those skilled in the art to achieve the guiding effect of the first actuator 33 on the loading assembly and guide and adjust the position and direction of the loading assembly. At the same time, the connection position of the first actuator 33 and the loading assembly is located at a position of the loading assembly far from the first driving assembly, so that the guiding mechanism can give the loading assembly a greater lever arm through the first actuator 33, more easily guide and adjust the position and direction of the loading assembly, and keep the loading assembly perpendicular to the choke valve 10. In this embodiment, the first actuator 33 is located above the loading assembly. In other embodiments, the first actuator 33 can also be arranged below the loading actuator or at other positions of the loading actuator according to the setting of the test tool.

[0109] The first driving assembly, the second driving assembly, the loading assembly and the frame 99 in Embodiment 2 have the same settings as the first driving assembly, the second driving assembly, the loading assembly and the frame 99 in Embodiment 1, as well as the same expansion of structural selection.

[0110] In other embodiments, the guiding mechanism of the test tool for following and loading the choke valve mechanism can simultaneously include a guiding plate 31 and a first actuator 33, or it can also be a guiding mechanism including other components. The other components are connected to the loading assembly through hinge connection, sliding connection or other movable connection manners conceivable by those skilled in the art, and provide a force to the loading assembly through hydraulic, electric, mechanical or other driving control methods conceivable by those skilled in the art, so as to form a resultant force with the first driving assembly on the loading assembly, and realize that during the real-time translation and rotation processes of the choke valve 10, the loading assembly is pushed to be perpendicular to the front surface of the choke valve 10.

[0111] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims.
