Description

Technical Field

[0001] The invention belongs to the technical field of lunar penetrators, and in particular to a lunar penetrator capable of preventing a communication module from tipping over. Background Art

[0002] In recent years, the exploration of extraterrestrial bodies has become a hot topic in international deep space exploration activities. The landing exploration modes include soft landing exploration mode and hard landing exploration mode. The soft landing exploration mode mainly relies on the reverse thrust engine to reduce the terminal velocity to zero to achieve a soft landing. Due to the small landing impact, this mode can carry a relatively rich functional operating equipment and detection payload, but its system structure is complex and the engineering cost is high. The hard landing exploration mode hits the surface of the planet at a high speed and penetrates to a certain depth, which is convenient for the detection of stellar soil at a certain depth. Compared with traditional soft landing exploration, hard landing exploration has the characteristics of simple structural system, good integration and flexible functional configuration. It is an efficient means to realize in-situ detection of the interior of extraterrestrial bodies and will be an important development direction for future extraterrestrial exploration missions.

[0003] As a hard landing detection mode, if the lunar penetrator is a two-stage configuration, that is, the penetration stage penetrates into the lunar soil to a certain depth for detection, and the communication module at the tail end of the power stage stays on the lunar surface to communicate with the relay satellite, then the communication module at the tail end of the power stage must face up after penetration and cannot overturn, so that the antenna and the relay satellite can communicate. If the components between the two ends of the power stage (such as the engine housing) are easily broken by impact, the penetration may cause the two ends of the power stage to separate, causing the communication module to overturn and flip, and unable to establish effective communication with the relay satellite. Therefore, it is necessary to design a reasonable limit device to prevent the two ends of the power stage from separating during penetration and causing the communication module to overturn and flip. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a lunar penetrator that prevents the communication module from overturning and flipping. Several limiting ropes evenly arranged along the circumference of the communication module are connected between the side wall of the communication module and the side wall of the non-fragile component. The communication module can be limited to prevent the communication module from overturning and flipping after the penetration of the lunar penetrator, thereby ensuring that the communication module and the relay satellite establish effective communication. The limiting ropes have a simple and reliable structure, light weight, and small size, which is conducive to the transportation of the lunar penetrator.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A lunar penetrator for preventing a communication module from tipping over and flipping over comprises a power stage, wherein the power stage comprises a communication module, a non-breakable component is connected below the communication module, and a plurality of limit ropes evenly arranged along the circumference of the communication module are connected between the side wall of the communication module and the side wall of the non-breakable component.

[0007] Preferably, a fragile component is provided between the non-fragile component and the communication module.

[0008] Preferably, the limiting rope is made of Kevlar fiber.

[0009] Preferably, there are six connection points between the communication module and the limiting rope, and at least two limiting ropes are provided at each connection point.

[0010] Preferably, it further comprises a penetration stage connected to the lower surface of the non-fragile component, and an umbilical cable is connected between the penetration stage and the non-fragile component.

[0011] Preferably, the side walls of the communication module and the non-fragile component are both provided with ears for fixing the limiting rope.

[0012] Preferably, the limiting rope is tied and fixed on the support ear by a weighing knot.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] Several limiting ropes evenly arranged along the circumference of the communication module are connected between the side wall of the communication module and the side wall of the non-fragile component, so as to limit the communication module to prevent it from overturning after the penetration of the lunar penetrator, thereby ensuring effective communication between the communication module and the relay satellite; the limiting ropes have a simple and reliable structure, are light in weight and small in size, and are conducive to the transportation of the lunar penetrator.

[0023] Combine the following Figure 1-Figure 3 The present invention is described in detail.

[0024] Example

[0025] A lunar penetrator that prevents a communications module from tipping over, such as Figure 1 As shown, it includes a power stage, which includes a communication module 4. A non-breakable component 2 is connected below the communication module 4. Several limiting ropes 5 evenly arranged along the circumference of the communication module 4 are connected between the side wall of the communication module 4 and the side wall of the non-breakable component 2.

[0026] The communication module 4 is reconnected to the non-breakable component 2 through the limit rope 5 to prevent the communication module 4 from tipping over. The non-breakable component 2, such as the structural member connecting the load stage (front stage) and the communication stage (rear stage), has a high structural strength.

[0027] A fragile component 3 is provided between the non-fragile component 2 and the communication module 4. The fragile component 3, such as the engine housing (empty shell) after working and burning, and the attitude control cylinder after working (if the attitude control adopts the cold air mode, the cylinder is empty after working), has a low structural strength. The fragile component 3 can play a certain buffering role on the communication module 4 to avoid damage to the communication module 4. The height difference between the fragile component 3 after deformation and the fragile component 3 before deformation is much smaller than the height of the communication module 4 to avoid the communication module 4 from flipping over.

[0028] The limit rope 5 is made of Kevlar fiber. The strength of Kevlar fiber is very high, which is 5 times that of steel of the same quality, while the density is only about one-fifth of that of steel. This high strength property makes Kevlar fiber not easy to be damaged when subjected to external force, thus showing excellent wear resistance. At the same time, Kevlar fiber also has high tear resistance, which further enhances its wear resistance. Therefore, the limit rope 5 made of Kevlar fiber can meet the needs of the lunar penetrator to penetrate.

[0029] There are six connection points between the communication module 4 and the limiting rope 5, and at least two limiting ropes 5 are set at each connection point. While ensuring that the communication module 4 is fixed by the limiting ropes 5 on all sides, the number of connection points is reduced as much as possible to reduce the number of ears 6 used and reduce the mass of the lunar penetrator. Therefore, the present application preferably uses six connection points to fix the limiting ropes 5, and two limiting ropes 5 are set at each connection point to meet the use requirements.

[0030] It also includes a penetration stage 1 connected to the lower surface of the non-fragile component 2, and an umbilical cable 7 is connected between the penetration stage 1 and the non-fragile component 2. The lunar penetrator penetrates the lunar soil 8 through the penetration stage 1, and the penetration stage 1 transmits the relevant detection data to the communication module 4 through the umbilical cable 7, and then the communication module 4 feeds back to the relay satellite.

[0031] The side walls of the communication module 4 and the non-fragile component 2 are both provided with ears 6 for fixing the limiting rope 5. The ears 6 are provided to assist in binding the limiting rope 5.

[0032] The limit rope 5 is tied and fixed on the support ear 6 by a weighing knot. Figure 3 After the method is wound, first tighten the B direction to tighten the knot, then tighten the B and A line ends at the same time to tighten the knot, and then tighten the C line end to tie the knot and the support ear 6 to fix it. The limit rope 5 will become tighter and tighter after being pulled.

[0033] When the present application is tested in the initial design stage, a penetration test on the ground is performed by mounting a lunar penetrator on a drone. Specifically: the lunar penetrator is mounted on a release device of the drone by a rope. During the test, the drone rises to a predetermined height, and after the posture is stabilized, the release device releases the lunar penetrator stationarily, and the lunar penetrator freely falls to the ground soil. After the test, whether the communication module 4 overturns and flips over is verified to verify the effectiveness of the limiting method of the limiting rope 5.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
