Description

Technical Field

[0001] This invention relates to a bundled rocket with solid rocket boosters, and more specifically to a device and method for precisely adjusting and installing a solid rocket booster for a bundled rocket. Background Technology

[0002] Launch vehicles can increase their carrying capacity by attaching boosters to the core stage. In the final stage of docking and installing the boosters with the core stage, the position of the boosters needs to be precisely adjusted by micro-motion. However, the boosters themselves have a large mass and a large inertia, making it difficult to achieve precise micro-motion adjustment of the booster position. The docking and installation process is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a device and method for precisely adjusting and installing a solid rocket booster for a rocket, thereby solving the problem of difficulty in precisely adjusting the position of the solid rocket booster during the docking process between the solid rocket booster and the core stage.

[0004] To achieve the above objectives, the present invention provides a precise adjustment and installation device for a solid rocket booster, comprising a precise adjustment and installation device for the booster tail and a precise adjustment and installation device for the booster front; the precise adjustment and installation device for the booster tail includes a pull rope, a tension reversing device, and a tension amplification device; both the tension reversing device and the tension amplification device are connected to the pull rope, one end of which is connected to the tail of the solid rocket booster, and the other end of which is the end for applying tension; the precise adjustment and installation device for the booster front is a telescopic link, with both ends of the telescopic link connected to the booster front and the core stage, respectively.

[0005] The aforementioned precision adjustment and installation device for the solid rocket booster is described above. The force reversing device is a fixed pulley, and the force amplification device is a movable pulley or a reducer. The fixed pulley is installed on the core stage, and the pull rope passes around the fixed pulley.

[0006] The aforementioned precision adjustment and installation device for bundling solid rocket boosters includes a telescopic connecting rod that is either a screw mechanism or a hydraulic device.

[0007] The aforementioned precise adjustment and installation device for solid rocket boosters is used as follows: After the solid rocket booster is hoisted to a position approximately equal to the core stage, the tail end of the solid rocket booster is precisely adjusted using the tail-end precise adjustment and installation device to install the tail end of the solid rocket booster onto the core stage; after the tail end of the solid rocket booster is installed onto the core stage, the front end of the solid rocket booster is precisely adjusted using the front-end precise adjustment and installation device to install the front end of the solid rocket booster onto the core stage.

[0008] The aforementioned precise adjustment and installation device for the solid rocket booster involves coarsely adjusting the position of the solid rocket booster. After this, the operator applies tension to the other end of the pull rope. A tension amplification device amplifies the tension, and a tension reversal device changes the direction of the tension. Through these two devices, the micro-adjustment of the solid rocket booster tail to the core stage is achieved, allowing the rear binding mechanisms installed on the solid rocket booster and core stage to precisely align. This ultimately completes the docking and installation of the solid rocket booster tail and the core stage.

[0009] The aforementioned precision adjustment and installation device for the solid rocket booster of the strapped rocket involves three sets of linkage assemblies to install the front part of the solid rocket booster with the core stage. After the tail part of the solid rocket booster is docked with the core stage, the front part of the solid rocket booster is coarsely adjusted into position. A precision adjustment and installation device for the front part of the booster is installed on the two linkage supports of the first linkage assembly, and another precision adjustment and installation device is installed on the two linkage supports of the second linkage assembly. By adjusting the two precision adjustment and installation devices, the distance between the solid rocket booster and the core stage is continuously reduced. When the distance between the two linkage supports of the third linkage assembly is equal to the length of the linkage of the third linkage assembly, the third... The connecting rods of the three sets of connecting rod assemblies are as follows: Remove the booster front precision adjustment mounting device from the two connecting rod supports of the first set of connecting rod assemblies; adjust the booster front precision adjustment mounting device from the two connecting rod supports of the second set of connecting rod assemblies until the distance between the two connecting rod supports of the first set of connecting rod assemblies is equal to the length of the connecting rod of the first set of connecting rod assemblies; then install the connecting rod of the first set of connecting rod assemblies; finally, remove the booster front precision adjustment mounting device from the two connecting rod supports of the second set of connecting rod assemblies and install the connecting rod of the second set of connecting rod assemblies; the connecting rods of the first set of connecting rod assemblies and the second set of connecting rod assemblies are parallel to each other, and the connecting rod of the third set of connecting rod assemblies forms an angle with both the connecting rods of the first set of connecting rod assemblies and the connecting rod of the second set of connecting rod assemblies.

[0012] The precise adjustment and installation device and method for the bundled rocket solid booster of the present invention are given in the following embodiments and figures.

[0013] Figure 1 This is a schematic diagram illustrating the precise adjustment and installation of the solid rocket booster tail and core stage in a preferred embodiment of the present invention.

[0014] Figure 2 This is a schematic diagram of the precise adjustment and installation of the front part of the solid rocket booster and the core stage in a preferred embodiment of the present invention. Detailed Implementation

[0015] The following will combine Figures 1-2 The present invention provides a more detailed description of the precise adjustment and installation device and method for the bundled rocket solid booster.

[0016] The present invention provides a precision adjustment and installation device for a solid rocket booster, comprising a booster tail precision adjustment and installation device and a booster front precision adjustment and installation device. The booster tail precision adjustment and installation device is used for fine-tuning the position of the solid rocket booster tail to achieve precise docking between the solid rocket booster tail and the core stage. The booster front precision adjustment and installation device is used for fine-tuning the position of the solid rocket booster front to achieve precise docking between the solid rocket booster front and the core stage.

[0017] The tail-end precision adjustment and mounting device of the booster includes a pull rope, a force reversing device, and a force amplification device; the front-end precision adjustment and mounting device of the booster is a telescopic linkage, such as a screw mechanism or a hydraulic device.

[0018] The present invention will now be described in detail with reference to specific embodiments, including the precise adjustment and installation device and method for the bundled rocket solid booster.

[0019] After the solid rocket booster is lifted by a crane to a position approximately equal to the core stage, the tail section of the solid rocket booster is precisely adjusted before installation of the tail section onto the core stage. This process is achieved using a precise adjustment and installation device for the tail section of the booster. After the tail section of the solid rocket booster is installed onto the core stage, the front section of the solid rocket booster is precisely adjusted before installation of the front section onto the core stage. This process is achieved using a precise adjustment and installation device for the front section of the booster.

[0020] Figure 1 The diagram shown is a schematic diagram of the precise adjustment and installation of the solid rocket booster tail and the core stage in a preferred embodiment of the present invention.

[0021] like Figure 1 In this embodiment, the force reversing device is a fixed pulley 11, and the force amplification device 12 is a movable pulley or a reducer.

[0022] A fixed pulley 11 is installed on the core stage; one end of a pull rope 13 is connected to the tail of the solid booster and then passes around the fixed pulley 11. A force amplification device 12 is connected to the pull rope 13, and the other end of the pull rope 13 is the end where the force is applied. When a force is applied to the other end of the pull rope 13, the force amplification device 12 amplifies the magnitude of the force, and the fixed pulley 11 changes the direction of the force.

[0023] After the solid rocket booster is coarsely positioned, the operator uses a tension amplification device and a tension reversal device to make precise micro-adjustments from the tail of the solid rocket booster to the core stage, so that the rear binding mechanisms 20 installed on the solid rocket booster and the core stage are precisely aligned, and finally the docking and installation of the tail of the solid rocket booster and the core stage is completed.

[0024] Figure 2 The diagram shown is a schematic diagram of the precise adjustment and installation of the front part of the solid rocket booster and the core stage in a preferred embodiment of the present invention.

[0025] The solid rocket with solid boosters is mounted to the core stage via three sets of linkage assemblies. Each linkage assembly includes two linkage supports and one connecting rod. The two linkage supports are mounted on the front of the solid booster and the core stage, respectively. The two ends of the connecting rod are connected to the two linkage supports. The three linkage assemblies are located in the same plane. The connecting rods of two linkage assemblies are parallel to each other, and the connecting rod of the third linkage assembly forms an angle with the connecting rods of the other two linkage assemblies.

[0026] Let there be three sets of linkage assemblies, namely linkage assembly A, linkage assembly B and linkage assembly C. The links of linkage assembly A and linkage assembly B are parallel to each other, and the links of linkage assembly C are at an angle to the links of linkage assembly A and linkage assembly B.

[0027] In this embodiment, the booster front precision adjustment and installation device adopts a screw mechanism, and there are two sets of booster front precision adjustment and installation devices.

[0028] Combination Figure 2 This demonstrates the precise adjustment and installation of the front section of the solid rocket booster with the core stage:

[0029] After the solid rocket booster's tail section is docked with the core stage, the front section of the solid rocket booster is coarsely adjusted to the correct position. A set of lead screw mechanisms is installed on the two link supports of link assembly A, and another set is installed on the two link supports of link assembly B. By adjusting these two sets of lead screw mechanisms, the distance between the solid rocket booster and the core stage is continuously reduced. When the distance between the two link supports of link assembly C equals the length of the connecting rod of link assembly C, the connecting rod of link assembly C is installed. The lead screw mechanisms on the two link supports of link assembly A are then removed. The lead screw mechanisms on the two link supports of link assembly B are adjusted. When the distance between the two link supports of link assembly A equals the length of the connecting rod of link assembly A, the connecting rod of link assembly A is installed. Finally, the lead screw mechanisms on the two link supports of link assembly B are removed, and the connecting rod of link assembly B is installed. After the three connecting rods are connected, the position of the front section of the solid rocket booster is fixed, completing the connection between the front section of the booster and the core stage.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
