A device for liquid rocket recovery

Abstract

This invention discloses a device for recovering liquid rockets, comprising a landing plate, a recovery platform, a magnetic attraction assembly, and a support column. The lower rocket assembly descends into the clearance hole of the recovery platform. At this time, the magnetic attraction assembly operates and generates magnetic poles. The magnetic poles generated by the magnetic attraction assembly are controlled to be the same as the magnetic poles of the landing plate. Utilizing the repulsion of like poles, the recovery platform generates a certain amount of counter-thrust on the entire rocket. The recovery and descent can be completed by shutting down the rocket engine, reducing the requirements for variable thrust and minimizing the impact during landing. During the recovery and descent process with the rocket engine off, the magnetic pole assembly can be manipulated to change the magnetic poles, achieving an attraction between opposite poles of the magnetic poles of the landing plate. When the rocket engine is shut down, the magnetic attraction force reduces small jumps or displacements of the entire rocket, improving the stability of the recovery and landing, and enhancing the reliability of the rocket for reuse.

Description

Technical Field

[0001] This application relates to the field of liquid rocket technology, and in particular to an apparatus for liquid rocket recovery. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this disclosure. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this disclosure.

[0003] With the development of aerospace technology, the carrying capacity of launch vehicles is severely insufficient, failing to meet the ever-increasing demand for satellite and other payload launches. Reusability of launch vehicles is the best way to solve this problem. Existing liquid rocket recovery methods suffer from drawbacks such as high technical difficulty, complex recovery processes, high recovery challenges, and stringent requirements for variable engine thrust, significantly increasing the cost of rocket recovery. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this application provides a device for liquid rocket recovery, so as to solve the problems of complex operation, high recovery difficulty and high requirements for rocket variable thrust performance of traditional recovery mechanisms in the existing technology.

[0005] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0006] An apparatus for recovering liquid rockets, comprising:

[0007] A landing plate, which is used to fix the rocket to the rocket and is magnetic;

[0008] A recovery platform, wherein the recovery platform has a clearance hole in the middle for the rocket to fall;

[0009] A magnetic suction assembly is disposed on the recovery platform, and the magnetic suction assembly can generate different magnetic poles to drive the landing plate to move away from or towards the recovery platform;

[0010] A support column is fixedly installed under the recycling platform.

[0011] Furthermore, the landing plate is rotatably connected to the rocket.

[0012] Furthermore, a deployment mechanism is provided between the landing plate and the rocket to allow the landing plate to be deployed or attached to the rocket.

[0013] Furthermore, the deployment mechanism is a telescopic rod.

[0014] Furthermore, the landing plate has a working position, and when the landing plate is in the working position, the landing plate unfolds in a direction perpendicular to the rocket axis.

[0015] Furthermore, the magnetic attraction assembly includes a coil group, which is connected via a cable to a controller for changing the direction and magnitude of the current in the coil group.

[0016] Furthermore, the landing plate is made of magnetic material.

[0017] Furthermore, the landing plate is equipped with the magnetic suction component.

[0018] Furthermore, the landing pads are provided in multiple portions and are evenly spaced apart.

[0019] Furthermore, the length of the landing plate is greater than the radius of the avoidance hole.

[0020] Compared with the prior art, the advantages of this application are:

[0021] This application involves fixing a magnetic landing plate to a rocket and mounting a recovery platform at the rocket's landing position via support columns. The recovery platform has a clearance hole in the center for the rocket's descent. A magnetic attraction component is installed on the recovery platform, generating different magnetic poles to drive the landing plate closer to or away from the platform. In actual use, when the rocket needs to land, it flies above the recovery platform, and its lower components fall into the clearance hole, reaching the landing plate's working position. At this point, the magnetic attraction component activates and generates magnetic poles. The magnetic poles generated by the magnetic attraction component are then controlled to interact with the magnetic field of the landing plate. By utilizing the repulsion of like magnetic poles, the recovery platform generates a certain amount of counter-thrust on the rocket as a whole. At this point, the rocket engine can be shut down to complete the recovery and descent operation, reducing the requirements for variable thrust of the rocket, making rocket recovery operations more convenient, and reducing the impact of rocket landing. During the recovery and descent process with the rocket engine shut down, the magnetic pole assembly can be manipulated to change the magnetic poles, achieving a state of attraction between opposite poles and the landing plate. When the rocket engine is shut down, the magnetic pole attraction force reduces small jumps or displacements of the rocket as a whole, improving the stability of recovery and landing, and improving the reliability of rocket reuse.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0027] like Figure 1 As shown, a device for liquid rocket recovery includes a landing plate 1, a recovery platform 2, a magnetic suction assembly, and a support column 3, wherein:

[0028] The landing plate 1 is fixedly mounted on the rocket 6 and is magnetic. The landing plate 1 moves synchronously with the rocket 6 and has a stable connection with the rocket 6 so that the landing plate 1 can transmit the force to the rocket 6 under the action of external force.

[0029] like Figure 2 As shown, the recovery platform 2 has a clearance hole 21 in the middle for the rocket 6 to fall. During the recovery and descent of the rocket 6, the rocket 6 can pass through the clearance hole 21 and fall directly to the recovery position, which is convenient and avoids direct collision with the recovery platform 2.

[0030] The magnetic suction component is installed on the recovery platform 2, and the magnetic suction component can generate different magnetic poles to drive the landing plate 1 to move away from or closer to the recovery platform 2. Depending on different operating conditions, the magnetic suction component can be operated to generate different magnetic poles to cooperate with the magnetic poles of the landing plate 1 to perform corresponding operating purposes.

[0031] The support column 3 is fixedly installed under the recovery platform 2. It can be pre-installed at the rocket 6 recovery position according to actual needs and can be moved and converted according to actual needs.

[0032] The working principle of this application is as follows: A magnetic landing plate 1 is fixed to the rocket 6, and a recovery platform 2 is erected at the landing position of the rocket 6 via a support column 3. The recovery platform 2 has a clearance hole 21 in the middle for the rocket 6 to fall. A magnetic attraction component is provided on the recovery platform 2. The magnetic attraction component can generate different magnetic poles to drive the landing plate 1 to move away from or towards the recovery platform 2. In actual use, when the rocket 6 needs to land, the rocket 6 flies above the recovery platform 2, and the lower components of the rocket 6 fall into the clearance hole 21 of the recovery platform 2 and reach the working position of the landing plate 1. At this time, the magnetic attraction component works and generates magnetic poles. The magnetic poles are the same as those of the landing plate 1. By utilizing the repulsion of like poles, the recovery platform 2 generates a certain amount of counter-thrust on the entire rocket 6. At this time, the rocket 6 engine can be shut down to complete the recovery and descent operation, reducing the requirements for the variable thrust of the rocket 6, making the recovery operation of the rocket 6 more convenient, and also reducing the impact degree of the rocket 6 landing. During the recovery and descent process of the rocket 6 engine shut down, the magnetic pole assembly can be operated to change the magnetic poles to achieve a state of attraction between opposite poles and the landing plate 1. When the rocket 6 engine is shut down, the magnetic pole attraction force reduces the small jumps or displacements of the entire rocket 6, improves the stability of the recovery and landing, and improves the reliability of the rocket 6 for reuse.

[0033] Furthermore, based on the above embodiments, the landing plate 1 is rotatably connected to the rocket 6 so that the landing plate 1 can rotate to different positions during normal flight and recovery of the rocket 6, so as to keep the drag coefficient of the rocket 6 from being affected by the landing plate 1, and can also play the role of the landing plate 1 during the recovery of the rocket 6.

[0034] Furthermore, based on the above embodiments, a deployment mechanism 4 is provided between the landing plate 1 and the rocket 6 to allow the landing plate 1 to be deployed or attached to the rocket 6. When it is necessary to change the rotation state of the landing plate 1, the deployment mechanism 4 can be used to drive the landing plate 1 to rotate relative to the rocket 6, thereby maintaining a stable and reliable driving effect.

[0035] Furthermore, based on the above embodiments, the deployment mechanism 4 is a telescopic rod, with the two ends of the telescopic rod connected to the rocket 6 and the landing plate 1, respectively. When the landing plate 1 needs to be deployed, the telescopic rod can provide a more stable support effect and occupy less space when the landing plate 1 is stored.

[0036] Furthermore, based on the above embodiments, the landing plate 1 has a working position. When the landing plate 1 is in the working position, the landing plate 1 unfolds in a direction perpendicular to the axis of the rocket 6. During the recovery of the rocket 6, the landing plate 1 can generate force with the magnetic attraction component with a larger area to achieve a larger and more stable reverse thrust state of the rocket 6, which can realize a more stable recovery of the rocket 6.

[0037] Furthermore, based on the above embodiments, the magnetic attraction component includes a coil group 51. The coil group 51 is connected to a controller 52 via a cable 53 for changing the direction and magnitude of the current on the coil group 51. Specifically, the magnetic attraction component is configured as a coil group 51 that can generate a magnetic field when energized. After the controller 52 is operated to energize the coil group 51, a circular magnetic field is generated in the space around the coil group 51. The position and orientation of the coil group 51 are set to keep the N pole or S pole facing the landing plate 1. The landing plate 1 has one of the magnetic poles, either N or S, so as to attract or push the landing plate 1 to move. According to the adjustment needs, the controller 52 can change the direction of the current passing through the coil group 51, thereby switching the N pole or S pole to complete the switching of the attraction or pushing state of the landing plate 1. At the same time, the magnitude of the current can be changed by the controller 52 to change the magnetic strength.

[0038] Furthermore, based on the above embodiments, the landing plate 1 is made of magnetic material, which, together with the magnetic poles generated by the magnetic pole assembly, forms the retro-thrust force during the recovery process of the rocket 6.

[0039] Furthermore, based on the above embodiments, the landing plate 1 is provided with the magnetic attraction component. By cooperating with the magnetic pole component on the landing plate 1 and the magnetic pole component on the recovery platform 2, a more flexible operation can be achieved.

[0040] Furthermore, based on the above embodiments, the landing plate 1 is provided in multiple forms and is evenly spaced, so that the force generated during the recovery of the rocket 6 is more uniform and stable, avoiding the risk of the rocket 6 tipping over.

[0041] Furthermore, based on the above embodiments, the length of the landing plate 1 is greater than the radius of the avoidance hole 21 in order to obtain a stable magnetic pole relative state and improve the reliability of recovering the rocket 6.

[0042] Furthermore, based on the above embodiments, the radius of the clearance hole 21 is larger than the radius of the rocket body 6. Specifically, the radius of the clearance hole 21 is more than 1.2 times larger than the radius of the rocket body 6, so that the rocket 6 can reliably fall into the clearance hole 21, reducing the control difficulty of the rocket 6.
