For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In the related art, during the design and verification process of the rotor system, it is necessary to test various performances of the rotor system. The related art generally uses a rotor tower to test the rotor. The rotor tower is not only complex in structure and operation, but also has a single function, making it difficult to test the performance of the entire rotor system.

[0044] In response to the above problems, the present application provides a rotor system testing device, system and method. The rotor system testing device has a simpler structure and is more convenient to operate.

[0045] For ease of understanding, the first direction in this embodiment is Figure 1 The Z-axis direction of the coordinate system, the second direction is Figure 1 The X-axis direction of the coordinate system, the third direction is Figure 1 The Y-axis direction of the coordinate system.

[0046] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0047] Figure 1 It is a schematic diagram of the structure of the rotor system testing device shown in an embodiment of the present application.

[0048] See also Figure 1A rotor system test device includes a guide device 100, a motion component 200 installed on the guide device 100, and a tension sensing component 600 connected to the motion component 200; wherein the guide device 100 and the motion component 200 cooperate in motion in a first direction Z, and the motion component 200 is provided with a mounting portion 221, and the mounting portion 221 is used to mount the rotor system 300 of the aircraft; when the rotor system 300 is running, the tension sensing component 600 is used to sense the tension generated by the motion component 200 in the first direction Z. The rotor system test device provided in the embodiment of the present application has a simpler structure, which not only avoids the defects of the rotor system test device of the related art that the function is single and the operation is complicated.

[0049] The rotor system 300 is also called a power set. The rotor system 300 includes a driving mechanism and a plurality of blades 310 connected to the driving mechanism. When the driving mechanism is running, the plurality of blades 310 can rotate. The rotor system test device provided in this embodiment can sense the tension generated by the motion component 200 when it moves through the tension sensing component 600, and then can perform tests such as blade effect, tension response and NVH (Noise, Vibration, Harshness) on the rotor system 300.

[0050] The first direction Z of this embodiment can be a vertical direction. After the motion component 200 is assembled on the guide device 100, the motion component 200 can move vertically upward or downward under the drive of the rotor system 300, and the guide device 100 can guide the movement of the motion component 200 in the vertical direction.

[0051] Since the rotor system 300 is installed on the motion component 200, when the rotor system 300 is running, the upward pulling force generated by the rotor system 300 is transmitted to the mounting seat 210 through the connecting arm 220. The mounting seat 210 and the guide device 100 move in coordination to generate an upward displacement. The mounting seat 210 is connected to the tension sensing component 600, and finally the tension measurement is realized.

[0052] Figure 2 yes Figure 1 A partially enlarged schematic diagram of a rotor system test device shown in an embodiment.

[0053] See also Figure 2 In some embodiments, the motion assembly 200 includes a mounting seat 210 and a connecting arm 220 connected to the mounting seat 210; the mounting seat 210 is mounted on the guide device 100, the length direction of the connecting arm 220 is along the second direction X, and the mounting portion 221 is disposed at one end of the connecting arm 220 away from the guide device 100. In this embodiment, the mounting portion 221 is used to detachably cooperate with the rotor system 300, so as to facilitate the replacement of different types of rotor systems 300 and to conduct tests on different types of rotor systems 300.

[0054] In some embodiments, the mounting portion 221 includes a fixing tool, which is connected to the rotor system 300 and is detachable relative to the connecting arm 220 and the rotor system 300, so that the fixing tool can be easily replaced to match different rotor systems 300 for testing.

[0055] In some embodiments, the guide device 100 includes a guide rail 110 extending along a first direction Z, and the mounting seat 210 is provided with a guide connection portion, which is ringed on the guide rail 110. The guide connection portion slides with the guide rail 110 in the first direction Z and is limited with the guide rail 110 in the second direction. That is, after the guide connection portion is assembled with the guide rail 110, the mounting seat 210 and the guide rail 110 have relative movement in the first direction Z, but no relative movement in the second direction X.

[0056] In this embodiment, the second direction X can be a horizontal direction, and the second direction X is parallel to the rotation plane of the blade 310 of the rotor system 300. The connecting arm 220 has a preset length. When the blade 310 of the rotor system 300 rotates, it will not interfere with the mounting seat 210 and the guide device 100.

[0057] In some embodiments, the connecting arm 220 is rotatably connected to the mounting base 210, and the rotation axis of the connecting arm 220 coincides with the axis center line of the connecting arm 220; the connecting arm 220 is transmission-connected to the first driving device 500, and the first driving device 500 is used to drive the connecting arm 220 to rotate.

[0058] The rotor system 300 of this embodiment may be a tilt rotor, and when the blades of the tilt rotor rotate, the entire rotor can tilt.

[0059] Continue to see Figure 2 In some embodiments, the connecting arm 220 is rotatably connected to the mounting seat 210 via a rotating mechanism. The rotating mechanism may be a turntable mechanism 230. The turntable mechanism 230 includes a fixed disk 231 and a rotating disk 232. The fixed disk 231 is connected to the mounting seat 210, and the rotating disk 232 is connected to the connecting arm 220. The first driving device 500 may be a turntable motor. The turntable motor is connected to the rotary transmission and can drive the rotating disk 232 to rotate, thereby driving the connecting arm 220 to rotate, so that the rotor system 300 tilts around the axis of the connecting arm 220, thereby realizing the testing of the multi-angle operating status of the rotor system 300.

[0060] It is understandable that the rotating structure 230 is not limited to a turntable mechanism, and in other embodiments, it may also be a rolling bearing.

[0061] In this embodiment, when the rotor system 300 is not tilted, since the rotation plane of the blades 310 of the rotor system 300 is along the horizontal direction, the tension of the rotor system 300 in the horizontal state can be tested at this time. When the rotor system 300 tilts forward or reversely at a preset angle, the rotation plane of the blades 310 of the rotor system 300 forms a certain inclination angle relative to the horizontal direction, and then the tension of the rotor system 300 in the tilted state can be tested. Since the first drive device 500 can drive the connecting arm 220 to rotate at different angles, the rotor system 300 can also be tested for tension at different tilt angles. Compared with related technologies, the testing function is richer.

[0062] In some embodiments, the connecting arm 220 may be assembled from a plurality of rod-shaped structures, or may be integrally formed.

[0063] The rotor system testing device of this embodiment also includes a second driving device 400 fixedly arranged relative to the guide rail 110, and a transmission member 410 is provided along the extension direction of the guide rail 110. One end of the transmission member 410 is transmission-connected to the second driving device 400, and the other end of the transmission member 410 is connected to the moving component 200. The second driving device 400 is used to drive the moving component 200 to move vertically upward or vertically downward through the transmission member 410.

[0064] See also Figure 1 In some embodiments, the second driving device 400 may be a winch motor, and the transmission member 410 may be a pull rope wound around the rotating shaft of the winch motor, and the end of the pull rope away from the winch motor is connected to the motion assembly 200. The pull rope may be made of metal material, such as steel, so the pull rope is also called a winch rope. When the winch motor rotates forward or reverse, the winch rope can be extended or shortened in the first direction Z.

[0065] In some embodiments, a motor bracket is provided at the top of the guide rail 110, and the winch motor is fixed to the guide rail 110 through the motor bracket. The motor bracket and the guide rail 110 are detachably connected to facilitate disassembly and assembly of the winch motor.

[0066] Figure 3 It is a schematic diagram of the coordination between the motion component and the guide device of the rotor system test device shown in one embodiment of the present application.

[0067] See also Figure 3 In some embodiments, at least two guide rails 110 are provided, and the two guide rails 110 are arranged in parallel in the third direction Y. Each guide rail 110 is provided with two guide portions 111, and the two guide portions 111 are respectively arranged on the back-to-back sides of the guide rail 110 along the second direction X; the guide connecting portion is provided with at least two connecting frames 2111, and the at least two connecting frames 2111 correspond to the at least two guide portions 111 one by one and are slidably matched.

[0068] In some embodiments, two guide rails 110 are provided, and the two guide rails 110 are connected as a whole through a connecting structure, and the cross-section of the structure connected as a whole is in an "I" shape.

[0069] The connecting frame 2111 is arranged in a ring around the corresponding guide rail 110, and two guide wheels 211111 are installed on the inner side of the connecting frame 2111. The guide rail 110 is located between the two guide wheels 211111, and the two guide wheels 211111 are respectively slidably matched with the two guide parts 111 of the guide rail 110. After such arrangement, the mounting seat 210 can not only slideably match with the guide rail 110 in the first direction Z, but also limit the mounting seat 210 with the guide rail 110 in the second direction X. In addition, the sliding of the mounting seat 210 in the first direction Z is made more stable.

[0070] In some embodiments, the connecting frame 2111 is a hollow rectangular structure, the guide rail 110 is inserted into the rectangular structure, and a guide wheel 211111 is respectively provided on two opposite side walls of the connecting frame 2111 in the first direction Z, and the guide rail 110 is clamped between the two guide wheels 211111.

[0071] In this embodiment, the guide rail 110 forms a protruding arc surface on both sides opposite to each other along the second direction X, and the arc surface is the guide part 111. The rotation axis of the guide wheel 211111 is along the third direction Y, so that the guide rail 110 can contact the arc surface and roll along the arc surface in the first direction Z.

[0072] In some embodiments, the guide wheel 211111 is provided with a concave surface in contact with the arc surface of the guide rail 110, so that the sliding fit between the guide wheel 211111 and the guide rail 110 is more stable.

[0073] It can be understood that the two opposite sides of the guide rail 110 along the second direction X can also form concave arc surfaces, and the guide wheel 211111 is provided with a convex surface in contact with the arc surface of the guide rail 110.

[0074] In some embodiments, the mounting base 210 includes a fixing plate 211, and the fixing plate 211 is arranged in a vertical direction. A connecting frame 2111 is fixed to the side of the fixing plate 211 facing the guide rail 110, and a mounting frame 212 is fixed to the side of the fixing plate 211 facing the connecting arm 220. The mounting frame 212 is assembled from a plurality of rod-shaped components, and an installation space is formed in the middle of the plurality of rod-shaped components. The first driving device 500 is accommodated in the installation space, which makes the structure more compact.

[0075] In some embodiments, two connecting frames 2111 are provided on one side of the fixing plate 211 facing the guide rail 110 in the first direction Z. The two connecting frames 2111 are spaced apart and connected to the guide rail 110 , which can further ensure the movement stability of the mounting base 210 .

[0076] It can be understood that the guide device 100 of this embodiment may not be limited to the matching mechanism of the guide rail 110 and the guide wheel 211111. In other embodiments, it can also be a matching mechanism of a gear and a rack, or a linear bearing mechanism, a slide rail and slider mechanism, etc.

[0077] It is understandable that the second driving device 400 is not limited to the winch motor, and the transmission member 410 is not limited to the winch rope. In other embodiments, the second driving device 400 can also be a cylinder, and the transmission member 410 can also be a chain or a rack.

[0078] In some embodiments, the winch motor may not be limited to being installed on the top of the guide rail 110 , but may also be installed on the bottom of the guide rail 110 . A pulley is provided on the top of the guide rail 110 , and the winch rope passes around the pulley and is connected to the motion component 200 .

[0079] The rotor system test device of this embodiment further includes a motion limiting component 700, which is disposed on the guide rail 110 at the side of the motion assembly 200 close to the top end of the guide rail 110, and is used to limit the vertical upward movement of the motion assembly 200. The motion limiting component 700 can be a limiting pin installed on the guide rail 110, and when the motion assembly 200 moves upward to contact the limiting pin, the motion assembly 200 can be limited.

[0080] The present embodiment does not limit the structure of the motion limiting component 700 . In other embodiments, the motion limiting component 700 may also be a limiting block or a limiting rod installed on the guide rail 110 .

[0081] In this embodiment, the motion limiting component 700 is detachably mounted on the guide rail 110. After removing the motion limiting component 700 and the winch motor, the operating assembly can be completely disassembled and assembled at the upper end of the guide rail 110. In some embodiments, the detachable manner can be threaded connection or clamping.

[0082] See also Figure 1 In this embodiment, the second driving device 400 can be installed at the top of the guide rail 110, and the guide rail 110 can support the second driving device 400. The guide rail 110 forms a sliding interval of a preset length along the first direction Z. The tension sensing component 600 is arranged between the motion component 200 and the bottom of the guide rail 110, and is detachably assembled on the guide rail 110; when the second driving device 400 drives the transmission member 410 to move vertically upward, the motion component 200 can be raised to the first position within the sliding interval, and the motion limiting component 700 can be set at the first position; when the second driving device 400 drives the transmission member 410 to move vertically downward, the motion component 200 can be lowered to the second position in the sliding interval, and the height of the second position is lower than the first position.

[0083] When the rotor system 300 is not in operation, since the rotor system 300 does not generate a pulling force along the first direction Z, the rotor system 300 is in the second position of the guide rail 110. When the rotor system 300 is in operation, the rotor system 300 generates a pulling force along the first direction Z, and the motion component 200 moves vertically upward under the driving of the pulling force until it moves to the second position and abuts against the motion limit component 700 and stops. Since the pulling force sensing component 600 is arranged on the guide rail 110 on the side of the motion component 200 close to the bottom end of the guide rail 110, the pulling force sensing component 600 can detect the pulling force of the motion component 200 during the upward movement of the motion component 200, and then can obtain the pulling force generated when the rotor system 300 is in operation.

[0084] In this embodiment, the second direction X can be a horizontal direction, and the second direction X is parallel to the rotation plane of the blades 310 of the rotor system 300. The connecting arm 220 has a preset length. When the blades 310 of the rotor system 300 rotate, they will not interfere with the mounting seat 210 and the guide device 100, so that the operation of the rotor system 300 remains within the lateral space area of ​​the guide device 100.

[0085] In this embodiment, at least one of the rotor system 300, the first drive device 500, the tension sensing component 600 and the second drive device 400 is electrically connected to the control device. The control device can control the first drive device 500 and the second drive device 400 to operate synchronously or asynchronously, and can obtain the tension information sensed by the tension sensing component 600, which can improve the automation level of the rotor system 300 test.

[0086] In this embodiment, the control device can send a control signal to the first drive device 500, and the rotating disk 232 of the first drive device 500 can be rotated to a specified angle through signal control, thereby realizing the testing of the multi-angle operating status of the rotor system 300.

[0087] When testing the rotor system 300, firstly, the second driving device 400 is controlled to operate so that the winch rope moves vertically downward, and the connecting arm 220 can be lowered to a lower height position; after the rotor system 300 is assembled on the connecting arm 220, the rotor system 300 is controlled to operate, and under the action of the tension, the rotor system 300 and the mounting assembly 200 move upward along the guide rail 110 until they are limited by the motion limiting component 700. During the upward movement of the rotor system 300, the first driving device 500 can be controlled by the control device to operate so that the connecting arm 220 rotates, thereby driving the entire rotor system 300 to tilt. The tilt angle can be controlled by controlling the operating state of the first driving device 500. Therefore, the rotor system testing device of this embodiment can test the tension of the rotor system 300 at different tilt angles.

[0088] In some embodiments, in order to keep the guide rail 110 stable in the vertical direction, the rotor system testing device also includes a support assembly, which is used to stabilize the guide rail 110 along the first direction Z. The support assembly is connected to the bottom of the guide rail 110 and is detachably connected to the guide rail 110.

[0089] In some embodiments, the support assembly further includes a support assembly, the support assembly includes a plurality of support members 120, the plurality of support members 120 are distributed at intervals on the periphery of the guide device 100 and connected to the guide device 100, for supporting the guide device 100 along the first direction Z.

[0090] A plurality of support rods 120 are arranged at the periphery of the guide rail 110, and are used to support the guide rail 110 together at the periphery, so that the guide rail 110 is kept in a vertical direction. The lower end of the guide rail 110 can be supported on the ground or other fixed objects, and the plurality of support rods 120 are in the shape of straight rods, and are arranged obliquely relative to the guide rail 110. The lower ends of the plurality of support rods 120 are spaced a certain distance from the guide rail 110 in the horizontal direction, and are supported on the ground or other fixed objects. The lower ends of the plurality of support rods 120 can be on the same supporting surface as the lower ends of the guide rail 110, and the upper ends of the plurality of support rods 120 are detachably connected to the guide rail 110, so that the support rods 120 and the guide rail 110 can be easily disassembled and assembled.

In some embodiments, the number of the support members 120 may be four, but is not limited thereto, and may be more than four, for example.

[0093] Before testing the rotor system 300, first assemble multiple support members 120 and the guide rail 110, and then support the guide rail 110 in the vertical direction; after the rotor system 300 is tested, remove the tension sensing component 600 on the guide rail 110, and then control the winch motor to lower the mounting base 210 to the lowest point of the guide rail 110.

The control device can control the first drive device 500 and the second drive device 400 to operate synchronously or asynchronously, and can obtain the tension information sensed by the tension sensing component 600, which can improve the automation level of the rotor system 300 test.

[0097] The control device can send control signals to the rotor system 300 and the first drive device 500, realize automatic operation of the rotor system through signal control, and control the rotating disk 232 of the first drive device 500 to rotate to a specified angle, thereby realizing the testing of the multi-angle operation status of the rotor system 300.
