Abstract
Description
Technical Field
[0001] This invention relates to the field of liquid rocket technology, and in particular to a dynamic stabilization device for propellant sloshing during sea-launched liquid rocket refueling. Background Technology
[0002] As rocket carrying capacity, satellite operational lifespan, and the complexity of deep space probe missions continue to increase, the proportion of liquid propellant in the total mass of spacecraft is also constantly rising. However, the sloshing of liquid propellant significantly affects the motion stability of spacecraft and the reliability of attitude and orbit control systems. The sloshing of large amounts of liquid propellant can generate substantial disturbance forces / torques on the spacecraft. If these disturbance forces / torques exceed the adjustable range of the control system or the structural tolerance, it will cause instability in the control system or structural damage.
[0003] Most marine rocket propellant loading is done on an ad-hoc, on-demand basis to ensure optimal launch conditions; propellant cannot be pre-loaded into the propellant tanks. This is because various checks and preparations are required before loading propellant into the rocket's fuel tanks to ensure its safety and reliability. Furthermore, during loading, parameters such as propellant flow and pressure must be monitored and controlled to prevent any problems. Pre-loading propellant into the tanks would increase the risk of rocket accidents. Additionally, due to the complex chemical properties of propellants, improper handling could cause environmental pollution and harm. Therefore, to ensure rocket safety, propellant is generally not pre-loaded into the tanks.
[0004] At this point, ships at sea need to store the propellant in advance according to requirements. In particular, the storage tanks need to be specially made and have anti-sway treatment to ensure that the propellant does not shake significantly within its respective storage tank. However, most existing anti-sway technologies directly adopt the anti-sway technology of rocket internal tanks, adding anti-sway blades inside the tank to ensure that the propellant does not shake significantly. But this can only prevent the propellant from shaking slowly, just like the anti-sway situation of propellant inside the tank. However, the shaking of ships at sea is not only due to the shaking of the tank during rocket launch, but also the shaking of the ship in multiple directions such as vertical, forward and backward, and left and right. Moreover, the shaking speed is much faster than the shaking speed inside the tank. Existing anti-sway technologies are insufficient. Summary of the Invention
[0005] Addressing the shortcomings of existing anti-sloshing technologies for propellant storage tanks on ships at sea, this invention proposes a dynamic stabilization device for propellant sloshing during sea-launched liquid rocket refueling.
[0006] The present invention proposes a dynamic stabilization device for propellant sloshing during sea-launched liquid rocket refueling, comprising a spherical tank for storing propellant, wherein the upper and lower ends of the spherical tank are provided with inlet and outlet pipes equipped with valves.
[0007] The outer surface of the middle part of the spherical tank is provided with a retaining ring that is adapted to the outer surface of the spherical tank, and the outer surface of the retaining ring is fixedly installed with outward support legs.
[0008] The inner wall of the retaining ring is provided with ball bearings that are rolled and connected to the outer surface of the spherical tank.
[0009] The retaining ring has an arc-shaped buffer mechanism arranged in a ring array along its vertical outer surface. When the ball can rolls along the inner wall of the retaining ring, the arc-shaped buffer mechanism buffers and adjusts the speed and posture of the ball can before and after rolling.
[0010] The outer surface of the spherical tank is also fixedly equipped with a central control mechanism for adjusting the arc-shaped buffer mechanism.
[0011] Preferably, the inner wall of the spherical tank is provided with a ball groove that is adapted to the surface of the ball, and the ball is assembled into the inner wall of the ball groove and then protrudes outward to roll and connect with the outer surface of the spherical tank.
[0012] The surface of the ball is provided with a lubrication groove, and the inner wall of the lubrication groove is filled with grease.
[0013] Through the above technical solution, the balls can be manufactured according to the manufacturing process of bearing balls, which increases the sensitivity of the ball rolling, and the grease in the lubrication groove can ensure that the balls can maintain good lubrication for a long time.
[0014] Preferably, the arc-shaped buffer mechanism consists of a buffer module and a pipeline module, wherein the buffer module controls the buffering action on the tank through the pipeline module.
[0015] Preferably, the buffer module includes an arc-shaped hydraulic cylinder fixedly installed inside the retaining ring, and a contact ball is fixedly installed at the end of the piston rod of the arc-shaped hydraulic cylinder.
[0016] A buffer ring is fixedly installed on the outer surface of the spherical tank, and the contact ball achieves a buffering action on the spherical tank through the buffer ring.
[0017] Through the above technical solution, the buffer ring can not only easily contact the contact ball, but also has the functions of limiting and protecting the bottom valve.
[0018] Preferably, the pipeline module includes a return spring that is movably sleeved inside the arc-shaped hydraulic cylinder. The return spring springs the piston rod downward after the piston rod slides to the top, thereby achieving the reset action.
[0019] With the above technical solution, the reset spring is set inside the arc-shaped hydraulic cylinder, which not only enables the piston rod to have a rebound force, but also prevents surface rusting and extends service life.
[0020] Preferably, the pipeline module further includes a hydraulic oil pipe connecting the oil inlet and outlet of the arc-shaped hydraulic cylinder. A one-way pipe is installed in parallel in the middle of the hydraulic oil pipe. An adjustable one-way flow valve and a one-way valve are respectively installed on the surface of the two one-way pipes. An adjusting gear is fixedly sleeved on the rotating adjusting end of the adjustable one-way flow valve. Then, the valve body of the adjustable one-way flow valve is fixedly installed on the outer surface of the retaining ring.
[0021] The above technical solution utilizes adjustable flow check valves and ordinary check valves to achieve the effect of controlling the retraction of the large-diameter arc-shaped hydraulic cylinder and the flow-controlled reset buffer action.
[0022] Preferably, when the piston rod of the arc-shaped hydraulic cylinder slides upward and retracts, hydraulic oil is forced out from the hydraulic oil pipe at the top, the return spring is compressed and accumulates elastic force, and the hydraulic oil flows from the one-way pipe equipped with the one-way valve into the bottom of the cylinder body of the arc-shaped hydraulic cylinder. The hydraulic oil does not perform the action of flowing to the bottom of the arc-shaped hydraulic cylinder through the adjustable one-way flow valve.
[0023] When the piston rod of the arc-shaped hydraulic cylinder is no longer under pressure, the compressed return spring rebounds and resets, and the hydraulic oil flows back from the bottom of the arc-shaped hydraulic cylinder to the top of the arc-shaped hydraulic cylinder through the adjustable one-way flow valve. At the same time, the hydraulic oil does not perform the action of flowing to the top of the arc-shaped hydraulic cylinder through the one-way valve.
[0024] The above technical solution can clearly describe the principle of buffering action, which is beneficial to the implementation of buffering action.
[0025] Preferably, the centralized control mechanism includes a guide fixing seat fixed to the surface of the retaining ring near the adjustable one-way flow valve, a micro motor is fixedly installed inside the guide fixing seat, a drive gear is fixedly sleeved on the output shaft of the micro motor, and a toothed ring is slidably connected inside the guide fixing seat, with the tooth surfaces of the two relatively distributed toothed rings meshing with the tooth surfaces of the drive gear and the adjusting gear.
[0026] After the drive gear rotates, it drives the gear ring to mesh and rotate with the adjusting gear, thereby adjusting the adjustable one-way flow valve.
[0027] The above technical solution can achieve integrated control of the arc-shaped buffer mechanism, and improve the transmission ratio and transmission efficiency of the pneumatic gear meshing, thereby enhancing the accuracy of the adjustment action.
[0028] Preferably, the support leg consists of a linear hydraulic cylinder and a connecting seat, wherein the cylinder body of the linear hydraulic cylinder is hinged to the connecting seat located at the bottom, and the piston rod of the linear hydraulic cylinder is fixedly connected to the connecting seat located at the top.
[0029] Through the above technical solution, the linear hydraulic cylinder and the connecting seat can buffer the vertical shaking of the spherical tank when it experiences up-and-down swaying.
[0030] Preferably, a gyroscope is fixedly installed at the vertical center of the bottom surface of the spherical tank.
[0031] The above technical solution allows the use of gyroscopes to collect data on the shaking of the spherical tank, providing more accurate data for the buffering action of the arc-shaped buffer mechanism.
[0032] The beneficial effects of this invention are as follows:
[0033] 1. By providing a retaining ring on the outer surface of the middle part of the spherical tank that is compatible with the outer surface of the spherical tank, the spherical tank containing propellant can be placed on the support leg in the air, which can avoid the problem of the spherical tank swaying with the ship after being directly installed on the ship.
[0034] 2. By setting up an arc-shaped buffer mechanism, it can prevent the spherical tank from shaking suddenly, and also prevent the spherical tank from shaking too much and causing the propellant to shake violently when it suddenly returns to its original position.
[0035] 3. By setting up a centralized control mechanism, the buffering action amplitude of the arc-shaped buffer mechanism can be adjusted according to the actual swaying of the ship, so that the arc-shaped buffer mechanism has better anti-swaying performance. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0048] Reference Figure 1-10 A dynamic stabilization device for propellant sloshing during sea-launched liquid rocket refueling includes a spherical tank 1 for storing propellant, with inlet and outlet pipes equipped with valves at both the upper and lower ends of the spherical tank 1.
[0049] like Figures 1-2 As shown, in order to detach the ball tank 1 from the ship and prevent it from swaying with the ship, a retaining ring 2 adapted to the outer surface of the ball tank 1 is provided on the outer surface of the middle part of the ball tank 1. The outer surface of the retaining ring 2 is fixedly installed with outward support legs.
[0050] By providing a retaining ring 2 on the outer surface of the middle part of the spherical tank 1 that is compatible with the outer surface of the spherical tank 1, the spherical tank 1 containing propellant can be suspended on the support leg, which can avoid the problem of the spherical tank 1 swaying with the ship after being directly installed on the ship.
[0051] like Figures 3-4 As shown, to enhance the rolling connection between the spherical tank 1 and the retaining ring 2, a ball bearing 3 is provided on the inner wall of the retaining ring 2, which rolls and connects with the outer surface of the spherical tank 1. A ball groove 31, adapted to the surface of the ball bearing 3, is formed on the inner wall of the spherical tank 1. After the ball bearing 3 is fitted into the inner wall of the ball groove 31, it protrudes outwards and rolls with the outer surface of the spherical tank 1. A lubrication groove 32 is formed on the surface of the ball bearing 3, and the inner wall of the lubrication groove 32 is filled with grease.
[0052] The ball bearing 3 can be manufactured using the same process as bearing balls, which increases the rolling sensitivity of the ball tank 1, and the grease in the lubrication groove 32 can ensure that the ball bearing 3 can maintain good lubrication for a long time.
[0053] like Figure 5 As shown, in order to reduce the swaying amplitude of the spherical tank 1 when it sways in the forward, backward, left and right directions of the ship, an arc-shaped buffer mechanism is provided on the outer surface of the ring 2 along its vertical direction. When the spherical tank 1 rolls along the inner wall of the ring 2, the arc-shaped buffer mechanism buffers and adjusts the speed and attitude of the spherical tank 1 before and after rolling.
[0054] The arc-shaped buffer mechanism consists of a buffer module and a pipeline module. The buffer module controls the buffering action on the tank through the pipeline module.
[0055] To ensure smooth and noiseless cushioning, the cushioning module includes an arc-shaped hydraulic cylinder 4 fixedly installed inside the retaining ring 2. A contact ball 41 is fixedly installed at the end of the piston rod of the arc-shaped hydraulic cylinder 4. The hydraulic oil inside the arc-shaped hydraulic cylinder 4 not only has a good shock absorption and cushioning effect, but also does not generate noise during hydraulic operation.
[0056] like Figure 10 As shown, in order to achieve the necessary limiting action of the arc-shaped hydraulic cylinder 4, a buffer ring 48 is fixedly installed on the outer surface of the spherical tank 1. The contact ball 41 achieves the buffering action of the spherical tank 1 through the buffer ring 48. The buffer ring 48 not only facilitates contact with the contact ball 41, but also has the functions of limiting and protecting the bottom valve.
[0057] like Figure 6As shown, in order to enable the spherical tank 1 to automatically reset after buffering, the piping module includes a reset spring 42 movably fitted inside the arc-shaped hydraulic cylinder 4. The reset spring 42 springs the piston rod back downwards after it slides upwards, thus achieving the reset action. The reset spring 42, located inside the arc-shaped hydraulic cylinder 4, not only provides the piston rod with a rebound force but also prevents surface rusting, extending its service life.
[0058] To better control the amplitude and speed of the reset action after buffering, the piping module also includes a hydraulic oil pipe 43 connecting the inlet and outlet of the arc-shaped hydraulic cylinder 4. A one-way pipe 44 is installed in parallel at the middle of the hydraulic oil pipe 43. An adjustable one-way flow valve 45 and a one-way valve 46 are respectively installed on the surfaces of the two one-way pipes 44. An adjusting gear 47 is fixedly sleeved on the rotating adjustment end of the adjustable one-way flow valve 45. The valve body of the adjustable one-way flow valve 45 is then fixedly installed on the outer surface of the retaining ring 2. By utilizing the adjustable flow one-way valve and the ordinary one-way valve 46, the retraction of the large-diameter arc-shaped hydraulic cylinder 4 and the flow-controlled reset buffer action are effectively controlled.
[0059] like Figures 5-8 As shown, the above buffer control action is implemented in the following way:
[0060] When the piston rod of the arc-shaped hydraulic cylinder 4 slides upward and retracts, hydraulic oil is forced out from the top hydraulic oil pipe 43, the return spring 42 is compressed and accumulates elastic force, and the hydraulic oil flows from the one-way pipe 44 equipped with the one-way valve 46 into the bottom of the cylinder body of the arc-shaped hydraulic cylinder 4. The hydraulic oil does not perform the action of flowing to the bottom of the arc-shaped hydraulic cylinder 4 through the adjustable one-way flow valve 45.
[0061] When the piston rod of the arc-shaped hydraulic cylinder 4 is no longer under pressure, the compressed return spring 42 rebounds and returns to its original position. Hydraulic oil flows from the bottom of the arc-shaped hydraulic cylinder 4 upwards through the adjustable one-way flow valve 45 to the top of the arc-shaped hydraulic cylinder 4. Simultaneously, the hydraulic oil does not flow through the one-way valve 46 to the top of the arc-shaped hydraulic cylinder 4. This provides a clear description of the buffering action principle, which is beneficial for achieving the buffering action.
[0062] By setting up an arc-shaped buffer mechanism, it is possible to prevent sudden shaking of the spherical tank 1 on the one hand, and to prevent the propellant from shaking too much when the spherical tank 1 suddenly returns to its original position.
[0063] like Figure 1 and Figure 9 As shown, in order to enable the buffer of the arc-shaped hydraulic cylinder 4 to be adjusted in a timely manner according to the different swaying conditions of the ship, a centralized control mechanism for adjusting the arc-shaped buffer mechanism is also fixedly installed on the outer surface of the spherical tank 1.
[0064] Specifically, the centralized control mechanism includes a guide fixing seat 5 fixed on the surface of the retaining ring 2 near the adjustable one-way flow valve 45. A micro motor 51 is fixedly installed inside the guide fixing seat 5. A drive gear 52 is fixedly sleeved on the output shaft of the micro motor 51. A toothed ring 53 is slidably connected inside the guide fixing seat 5. The tooth surfaces of the two relatively distributed toothed rings 53 mesh with the tooth surfaces of the drive gear 52 and the adjusting gear 47. After the drive gear 52 rotates, it drives the toothed ring 53 to mesh and rotate with the adjusting gear 47, thereby realizing the action of adjusting the adjustable one-way flow valve 45.
[0065] It can achieve integrated control of the arc-shaped buffer mechanism, and the gear meshing transmission ratio and transmission efficiency can improve the accuracy of the adjustment action.
[0066] By setting up a centralized control mechanism, the buffering action amplitude of the arc-shaped buffer mechanism can be adjusted according to the actual swaying of the ship, so that the arc-shaped buffer mechanism has better anti-swaying performance.
[0067] like Figure 10 As shown, in order to buffer the vertical swaying of the spherical tank 1, the support leg is composed of a linear hydraulic cylinder 6 and a connecting seat 61. The cylinder body of the linear hydraulic cylinder 6 is hinged to the connecting seat 61 located at the bottom, and the piston rod of the linear hydraulic cylinder 6 is fixedly connected to the connecting seat 61 located at the top. The linear hydraulic cylinder 6 and the connecting seat 61 can buffer the vertical swaying of the spherical tank 1 when it experiences vertical shaking.
[0068] Furthermore, a gyroscope 7 is fixedly installed at the vertical center of the bottom surface of the spherical tank 1.
[0069] A gyroscope can be used to collect data on the swaying of the spherical tank 1, providing more accurate data for the buffering action of the arc-shaped buffer mechanism. The data collected from the gyroscope 7 can also be used to directly control the adjustable one-way flow valve 45 in the arc-shaped buffer mechanism, thereby controlling the reset attitude and speed of the spherical tank 1. Alternatively, it can be directly connected to the gyroscope data on the hull.
[0070] When the hull rolls, the gyroscopic torque forces the frame, carrying the rotor, to rotate relative to the hull. This oscillating rotation generates another gyroscopic torque, providing stability to the hull. The Sperry active stabilizer adds a small maneuvering gyroscope to the aforementioned device, with its rotor positioned along the ship's transverse axis. Once the hull rolls, the small gyroscope rotates along its vertical axis, causing the control motor on the main gyroscope frame axis to activate promptly. This motor applies an active torque in the same direction as the original gyroscopic torque, thereby enhancing the frame's rotation and the resulting stabilizing effect on the hull. The same technology can also be used in arc-shaped buffer mechanisms for better stability of the tank 1.
[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
