Description

Technical Field

[0001] This invention relates to the field of rocket launch technology, and more specifically to a fast, automatically detachable connector, its design method, and a rocket launch system. Background Technology

[0002] Modern launch vehicles have numerous gas and liquid pipelines connecting to ground equipment during the launch preparation phase, with some pipelines connecting to the rocket itself until liftoff. Current rockets are equipped with numerous rocket-to-ground interface devices for onboard pressurization and propellant loading. The gas-liquid connector, as a critical interface between the launch vehicle and the ground gas-liquid pipelines, directly impacts the rocket launch process due to its reliability. Currently, gas-liquid connectors are equipped with locking mechanisms to reliably lock the connector to the rocket interface and to allow for connector detachment before or during liftoff. Reliable connector locking during propellant loading prevents propellant leakage and ensures the safety of the loading process.

[0003] The locking device of a connector is a core component, requiring targeted research to ensure its reliable operation. Different locking devices have different mechanical environments and application ranges. Many currently operational launch vehicles use cryogenic propellants, resulting in very low temperatures at the rocket-to-ground interface. Therefore, research is needed on locking mechanisms that can reliably lock at low temperatures. Most mainstream connectors in current technology employ claw-type, ball-lock, pull-out, or burst-type connectors. However, these connectors are structurally overly complex. Furthermore, the multi-point release synchronization of claw-type and ball-lock connectors is difficult to control. Pull-out and burst-out unlocking connectors are disposable products, containing untestable features, and their usage costs are high.

[0004] Therefore, there is an urgent need for a simple, reusable, and fast automatic connector. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a fast and automatic disconnecting connector, a design method, and a rocket launch system, which is not only simple in structure but also reusable, thus greatly saving costs.

[0007] The on-rocket flange connects to the rocket's propellant loading port;

[0008] The docking flange is connected to the end of the pipeline and is used to dock with the flange on the arrow.

[0015] In some possible implementations, a sealing assembly is provided between the docking flange and the arrow flange, the sealing assembly being one or more sealing rings, each of the sealing rings being disposed within the sealing groove of the docking flange;

[0016] The outer sides of the joint between the arrow flange and the mating flange are both V-shaped surfaces, and the inner surface of the wrapping tape is a V-shaped groove that matches the V-shaped surface.

[0017] In some possible implementations, the inner opening of the arrow flange is provided with a recess, and the mating flange is provided with a boss that matches the recess. The mating flange is mated with the arrow flange through the boss and the recess.

[0018] In some possible implementations, the connector further includes: a tensioning element;

[0019] The tensioning element is disposed between any two adjacent sub-joints and is used to tension multiple joints;

[0020] The tensioning element is a pull tab or a double-ended stud.

[0026] Step S5: Based on the pipe diameter, the sealing structure material, the connector material, the connector structure, and the unlocking method, a reliability design is performed. The reliability design includes strength reliability, stiffness reliability, and media compatibility reliability.

[0027] Step S6: Based on reliability design and in conjunction with process design, conduct preliminary structural design, locking design, and unlocking design; among which,

This design, using only flange docking, is simple in structure and can adapt to different pipe diameters. By quickly unlocking the multi-joint strap through the unlocking mechanism, the connector automatically unlocks and detaches, meeting 0-second detachment requirements. Furthermore, it is reusable, significantly reducing costs. Attached Figure Description

[0053] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the invention; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0054] A rocket gas-liquid connector is a ground-based device used to supply gas and liquid to a rocket, interfacing with the gas or liquid filling port on the rocket. It can detach from the rocket body surface before liftoff. The connector provided in this invention can be applied to gas-liquid connectors such as liquid oxygen filling connectors, methane filling connectors, kerosene filling connectors, nitrogen tetroxide filling connectors, unsymmetrical dimethylhydrazine filling connectors, and air conditioning connectors.

[0055] Figure 1 This is an assembly diagram of a fast-release, automatically disconnecting connector according to an embodiment of the present invention, as shown below. Figure 1As shown, the connector includes: a pipe 1, an on-rocket flange 2, a docking flange 3, a multi-joint strap 4, and an unlocking mechanism 5; wherein, the on-rocket flange 2 is connected to the propellant loading port of the rocket; the docking flange 3 is connected to the end of the pipe 1 for docking with the on-rocket flange 2; after the docking flange 3 docks with the on-rocket flange 2, it is connected and pressed together by the multi-joint strap 4; the multi-joint strap 4 is provided with an unlocking mechanism 5 at the joints, and after the multi-joint strap 4 is unlocked by the unlocking mechanism 5, the pipe 1 and the docking flange 3 automatically detach from the on-rocket flange 2.

[0056] The connector provided in this embodiment of the invention has a simple structure, which is achieved by flange connection only. The length of the multi-joint wrapping tape 4 can be arbitrarily selected to adapt to different pipe diameters 1. The multi-joint wrapping tape 4 can be quickly unlocked by the unlocking mechanism 5 to achieve automatic unlocking and detachment of the connector. It can meet the 0s detachment requirement and can be reused, which can greatly save costs.

[0057] Figure 2 This is an overall schematic diagram of a multi-joint strap according to an embodiment of the present invention. Figure 3 This is a partial schematic diagram of a multi-joint bandage according to an embodiment of the present invention, as shown below. Figure 2 and Figure 3 As shown, in some embodiments, the multi-joint strap 4 includes several sub-joints 41. Any two sub-joints 41 are connected by an unlocking mechanism 5 and a connector 42. The number of unlocking mechanisms 5 is greater than or equal to two to achieve unlocking redundancy and avoid jamming during unlocking. Optionally, the connector 42 and the unlocking mechanism 5 are alternately arranged among the several sub-joints 41 to achieve unlocking redundancy while fully avoiding jamming during unlocking. In addition, the material of the multi-joint strap 4 can be non-metallic or metallic, but it is best to have a high hardness to avoid plastic deformation after compression.

[0058] In this embodiment, the number of sections of the multi-joint strap 4 can be adaptively adjusted according to the circumference of the flange. The number of strap sections can be appropriately increased. Since there is a gap between two adjacent sub-joints 41, the overall flexibility of the multi-joint strap can be increased, and jamming can be avoided during unlocking. In this embodiment, the connector 42 can be any component that can movably connect two adjacent sub-joints 41, such as a bolt.

[0059] Figure 4 This is a schematic diagram of an unlocking mechanism according to an embodiment of the present invention, as shown below. Figure 4As shown, in some embodiments, the unlocking mechanism 5 includes an unlocking pin 51 and a steel cable 52. One end of the unlocking pin 51 is positioned between any two adjacent sub-joints 41, and the other end of the unlocking pin 51 is connected to the steel cable 52. Specifically, the joints are connected by the unlocking pin 51. When the unlocking pin 51 is pulled out by the steel cable 52, the two flanges can be unlocked. In this embodiment, the unlocking pin 51 and the steel cable 52 are used together. When unlocking, the unlocking pin 51 is pulled out from the joint connection by the steel cable 52 to unlock the multi-joint strap 4, achieving 0-second unlocking and detachment.

[0060] Figure 5 This is a schematic diagram of a sub-joint according to an embodiment of the present invention, as shown below. Figure 5 As shown, in some embodiments, one end of the sub-joint 41 is a single ear plate 411, and the other end is a double ear plate 412. Both the single ear plate 411 and the double ear plate 412 have holes in the middle. The two sub-joints 41 are movably connected together by an unlocking mechanism 5 or a connector 42 passing through the hole of the single ear plate 411 of one sub-joint 41 and the hole of the double ear plate 412 of an adjacent sub-joint 41. In this embodiment of the invention, by movably connecting the single ear plate 411 of one sub-joint 41 with the double ear plate 412 of an adjacent sub-joint 41, the joint can be movably connected while improving the flexibility between the joints.

[0061] Figure 6 This is a split diagram of a fast, automatically detachable connector according to an embodiment of the present invention. Figure 6 This is a schematic diagram of the structure of a sealing ring according to an embodiment of the present invention, as shown below. Figure 5 and Figure 6 As shown, in some embodiments, a sealing assembly is provided between the mating flange 3 and the upper flange 2. The sealing assembly consists of one or more sealing rings 6, each of which is disposed within a sealing groove of the mating flange 3. In the implementation of this invention, double or multiple seals can be performed according to actual needs. The material of the sealing rings 6 can be metal (e.g., aluminum) or non-metal (e.g., rubber, polytetrafluoroethylene, etc.) to achieve a structure with high sealing requirements.

[0062] In some embodiments, the articulated strap 4 is fitted to the outer mating surfaces of the upper flange 2 and the mating flange 3. For example, the outer surfaces of the mating surfaces of the upper flange 2 and the mating flange 3 are both V-shaped surfaces, and the inner surface of the articulated strap 4 is a V-groove structure that matches the V-shaped surface. By fitting the articulated strap 4 to the flange surfaces, it is easy for the articulated strap 4 to detach from the upper flange 2 and the mating flange 3 after the unlocking pin 51 is pulled out.

[0063] Figure 7 This is a schematic diagram of the structure of an arrow flange according to an embodiment of the present invention. Figure 8 This is a schematic diagram of the structure of a mating flange according to an embodiment of the invention, such as... Figure 7 and Figure 8 As shown, in some embodiments, the inner opening of the arrow flange 2 is provided with a recess 21, and the mating flange 3 is provided with a boss 31 that matches the recess 21. The mating flange 3 is mated with the arrow flange 2 through the boss 31 and the recess 21.

[0064] In this embodiment, the recess 21 can be chamfered or trapezoidal in shape. The boss 31 engages with the recess 21 to position the two flange faces, facilitating precise docking. Furthermore, the boss 31 can withstand the shear force generated by gravity during the filling process, reducing the load-bearing requirements of the multi-joint strap 4. The shear force refers to the weight of the connector itself and the weight of the liquid inside the connector, acting as shear force.

Figure 9 As shown, in some embodiments, the connector further includes a tensioning member 7; the tensioning member 7 is disposed between any two adjacent sub-joints 41 for tensioning multiple sub-joints 41; the tensioning member 7 is a pull tab or a double-ended stud. In this embodiment, multiple joints can be tensioned by the tensioning member 7, which can be... Figure 9 The buckle structure shown can be tightened by adjusting the length of the multi-joint strap 4 through the middle screw, or by tightening through the double-headed stud. The length of the multi-joint strap 4 can be tightened by adjusting the threads at both ends.

[0066] Figure 10 This is a flowchart illustrating a design method for a rapid, automatically detachable connector according to an embodiment of the present invention. Figure 11 This is a deployment diagram of a design method for a rapid, automatic disconnection connector according to an embodiment of the present invention, as shown below. Figure 10 and Figure 11 As shown, the present invention also provides a design method for a rapid, automatically detachable connector, the design method comprising the following steps:

[0067] Step S1: Calculate the flow resistance based on the flow rate and velocity requirements, and determine the pipe diameter of pipe 1 based on the flow resistance.

[0068] In practical applications, excessively high flow velocities can lead to excessive hydraulic demands and also result in high flow resistance. Therefore, in the overall connector design, under the condition of a constant flow rate, a balance must be struck between the distribution of flow velocity and the cross-sectional area of ​​pipe 1. With a constant flow rate, the larger pipe 1 is, the slower the flow velocity; flow velocity refers to the speed at which the propellant flows.

[0069] Step S2: Select connector material based on media compatibility.

[0070] In this embodiment, the compatibility of the propellant medium and the connector material must be considered to avoid oxidation, corrosion, or electrochemical reactions. Where compatibility is permissible, some non-metallic materials, such as polytetrafluoroethylene (PTFE) plastic or rubber, can be appropriately selected.

[0071] In some embodiments, the sealing structure material is selected based on the medium temperature requirements and medium compatibility. For example, the temperature of hot gas may be 60 degrees Celsius, and the temperature of cryogenic propellant liquid oxygen may be 66K. Propellants at different temperatures exhibit different expansion and contraction; cryogenic materials are used for cryogenic sealing, and high-temperature materials are used for high-temperature sealing. In this embodiment, it is necessary to consider not only the medium compatibility between the propellant medium and the connector material, but also the medium compatibility between the propellant medium and the sealing structure material to avoid oxidation, corrosion, or electrochemical reactions. The sealing material can also be non-metallic or metallic O-state aluminum, etc.

[0072] Step S3: Design the connector structure according to the installation requirements.

[0073] These include weight requirements, space requirements, and guidance requirements. For example, the weight should be light, the structure simple, and it should meet the installation and operation space reserved at the interface on the arrow. It should also be easy to operate and connect in terms of space, and have high reliability in terms of guidance and low requirements for operators.

[0074] Step S4: Design an unlocking method based on the detachment requirements.

[0075] The unlocking method must meet the requirement of 0s detachment and not produce any extra material (i.e., no uncontrollable fragments or objects). The unlocking force can come from the separating steel cable or other energy sources.

[0076] Step S5: Based on the pipe diameter, connector material, connector structure and unlocking method of pipe 1, a reliability design is carried out. The reliability design includes strength reliability, stiffness reliability and media compatibility reliability.

[0077] Specifically, reliability design is carried out based on the design requirements of steps S1 to S5, including designs for strength reliability, stiffness reliability, and media compatibility reliability. Strength reliability can be achieved by reserving a safety margin. A safety margin means that the actual stress state of the material must be less than its bearing capacity limit; the greater the margin, the larger the safety margin. For example, if the actual structural stress is 400 MPa and the usable strength of the material is 800 MPa, then the safety factor is 2. Media compatibility reliability can be achieved through the physicochemical properties of different materials and testing. Optionally, reliability design also includes sealing reliability, which can be achieved through different sealing schemes or multiple seals.

[0078] Step S6: Based on the reliability design and combined with the process design, conduct preliminary structural design, locking design, and unlocking design.

[0079] The preliminary structural design includes: using the arrow flange 2 and the docking flange 3 for connection. Since flange docking is simple and reliable, the connection method is designed as flange docking. The dimensions of the arrow flange 2 and the docking flange 3 can be determined according to the diameter of the pipeline 1.

[0080] The locking design includes: connection and clamping via a multi-joint strap 4;

[0081] The unlocking design includes: unlocking the multi-joint strap 4 via the unlocking mechanism 5 to unlock the docking flange 3 and the arrow flange 2.

[0082] In this embodiment, the difficulty lies in the connection and unlocking between the two flanges. This embodiment of the invention designs a connection and unlocking scheme with a multi-joint strap 4. The two flanges are connected and pressed together by the multi-joint strap 4. The multi-joint strap 4 can be designed according to the size of the flange. The multi-joint strap 4 is unlocked by the unlocking mechanism 5 to unlock the flange face.

[0083] In some embodiments, step S6 may further include: performing sealing design and weight optimization design based on reliability design and in conjunction with process design.

[0084] The sealing design includes determining the sealing structure based on the temperature of the propellant medium. For example, the temperature of hot gas might be 60 degrees Celsius, while that of cryogenic propellant liquid oxygen might be 66K. The different expansion and contraction of propellants at different temperatures affect the selection of the sealing structure. Cryogenic materials can use cryogenic sealing methods, while high-temperature materials can choose high-temperature sealing methods. Specifically, sealing grooves and sealing rings can be incorporated into the flange face. For structures with high sealing requirements, double sealing with two sealing rings or multi-ring sealing with multiple sealing rings can also be used.

[0085] Weight optimization design includes optimizing the structural weight through finite element strength calculations to improve material utilization efficiency. This can be achieved using software like Abaqus to perform strength calculations and assess the structural safety margin. If the safety margin is too large, weight reduction optimization can be implemented to design a compact and reliable connector that meets the requirements.

[0086] The connector designed using the method provided in this invention can adapt to different pipeline diameter requirements, ranging from small diameter (50mm) to large diameter (1000mm), with a wide range of applications. Furthermore, it has a simple structure, consisting only of flange connections and using traditional sealing rings for high sealing reliability. It also exhibits strong adaptability to high and low temperature deformation, accommodating both ambient and cryogenic propellants. Additionally, it is lightweight, easy to operate, reusable, and can meet the requirement of Os detachment.

[0087] In addition, embodiments of the present invention also provide a rocket launch system, which includes an automatically detachable connector.

[0088] The connector used in the rocket launch system of this embodiment can adapt to the requirements of different pipeline diameters, ranging from small diameter (50mm) to large diameter (1000mm), with a wide range of applications. Moreover, it has a simple structure, consisting only of flange connection and using traditional sealing rings for high sealing reliability. At the same time, it has strong adaptability to high and low temperature deformation and can adapt to both room temperature and cryogenic propellants. Furthermore, it is lightweight, easy to operate, reusable, and can meet the requirements for 0s detachment.
