Description

Technical Field

[0001] The present application relates to the field of rocket technology, and in particular to a combined deflector. Background Art

[0002] When launching a rocket, a deflector (or guide trough) is needed to smoothly guide the engine gas jet and keep the gas away from the launch area. The size of the deflector (or guide trough) is related to the diameter of the rocket and the number of engines. Small rockets generally use small-sized deflectors to meet the needs of tail flame guidance. As the diameter of the rocket increases and the number of engines increases, larger deflectors are required.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] It is understood by those skilled in the art that the large and medium-sized rockets in the embodiments of the present application generally refer to liquid fuel rockets, and do not include solid fuel rockets, and the diameter of the rocket is generally above 3.8 meters. In this way, during the launch of this type of rocket, the outer dimensions of the deflector are more than 10 meters in length, more than 4.5 meters in width, and more than 4 meters in height, and the mass is estimated to be more than 50 tons. If such a large deflector is formed in one piece, it will be difficult to form. Secondly, the deflector generally needs to be processed in the workshop, and then transported to the launch site after the processing is completed. If it is formed in one piece, during the transportation process, due to the large volume and weight of the deflector, it will be subject to transportation restrictions, resulting in transportation troubles. Even if a special channel is applied for transportation, due to the large mass of the deflector, a large-tonnage crane is required for overall lifting. If a single hook is used for lifting, a truck crane greater than 200 tons is required, and when loading and unloading vehicles at the launch site, a large-tonnage truck crane is not easy to guarantee and the cost is high.

[0025] Please refer to Figure 1 and Figure 2 Based on this, the present application provides a combined deflector for launching large and medium-sized rockets, the combined deflector comprising a first component 100 and a second component 200; the first component 100 comprises a first docking surface, the second component 200 comprises a second docking surface, the first docking surface fits the second docking surface, and the first component 100 and the second component 200 are detachably fixedly connected. It can be understood by those skilled in the art that the first docking surface can be a plane, a smooth curved surface, or composed of multiple planes. Those skilled in the art can set it according to specific circumstances, and the embodiments of the present application do not impose specific restrictions. On the same day, the second docking surface should be able to completely fit with the first docking surface. It can also be understood by those skilled in the art that the complete fit here should take into account the error problem in actual processing. For example, if the first docking surface and the second docking surface fit 90%, 95%, etc., it should also be considered that the first docking surface and the second docking surface are completely fit.

[0026] In the embodiment of the present application, the traditional one-piece molding method of the deflector is changed, and the deflector is divided into a first component 100 and a second component 200 that are detachably fixedly connected for processing, so that the weight and volume of the first component 100 and the second component 200 can be reduced. Therefore, for the first component 100 and the second component 200 after being split, the processing difficulty will be reduced, and the transportation conditions can be met, which is convenient for transportation. After the first component 100 and the second component 200 are transported to the rocket launch site, they can be fixed and assembled on the spot, thereby avoiding the situation in the prior art that is inconvenient for processing and transportation, thereby reducing the difficulty of rocket launch preparation and improving efficiency.

[0027] Please refer to Figure 3 and Figure 4 In some embodiments, the first component 100 includes a first substrate 110 and a first thermal insulation pad 120; the first substrate 110 includes an adjacent first upper surface 111 and a first side surface 112, the first side surface 112 faces the side of the second component 200, the first side surface 112 constitutes the first docking surface, and the first thermal insulation pad 120 covers the first upper surface 111; the second component 200 includes a second substrate 210 and a second thermal insulation pad 220; the second substrate 210 includes an adjacent second upper surface 211 and a second side surface 212, the second side surface 212 faces the side of the first component 100, the second side surface 212 constitutes the second docking piece, and the second thermal insulation pad 220 covers the second upper surface 211.

[0028] Those skilled in the art will appreciate that the first substrate 110 and the second substrate 210 can be made of metal materials, such as cast iron, so that they have high strength and thermal conductivity, so that they can resist the impact of the airflow of the tail flame during rocket launch and can quickly transfer heat away. Those skilled in the art will also appreciate that when the rocket is launched, the temperature of the tail flame is extremely high. In order to avoid direct damage to the first substrate 110 and the second substrate 210 by the tail flame and increase the number of recycling uses of the first substrate 110 and the second substrate 210, in the embodiment of the present application, a first thermal insulation pad 120 is provided on the upper surface of the first substrate 110, and a second thermal insulation pad 220 is provided on the upper surface of the second substrate 210. Those skilled in the art will also appreciate that in the embodiment of the present application, the upper surface of the first substrate 110 and the upper surface of the second substrate 210 refer to the surfaces of the first substrate 110 and the second substrate 210 that can contact the rocket tail flame during the rocket launch. Those skilled in the art will also appreciate that the combined deflector in the embodiment of the present application can have different combinations, such as Figure 2As shown, it can be a combination type along the length direction. At this time, the upper surface of the first substrate 110 and the upper surface of the second substrate 210 refer to the surface of the first substrate 110 and the second substrate 210 facing upward; and when the first substrate 110 and the second substrate 210 are combined in the height direction, at this time, the upper surface of the first substrate 110 refers to the surface of the first substrate 110 facing upward, and the upper surface of the second substrate 210 refers to the surface of the second substrate 210 on both sides along the length direction. It can also be understood by those skilled in the art that in the embodiment of the present application, the height direction refers to the direction from the combined deflector to the rocket, and the length direction is perpendicular to the height direction. In the embodiment of the present application, by setting the first thermal insulation pad 120 and the second thermal insulation pad 220, the damage of the rocket tail flame to the first substrate 110 and the second substrate 210 during rocket launch can be reduced, and the service life of the first substrate 110 and the second substrate 210 can be increased. It can also be understood by those skilled in the art that the first thermal insulation pad 120 and the second thermal insulation pad 220 can be replaced as consumables.

[0029] Please continue to refer to Figure 3 and Figure 4 , the first side surface 112 fits the second side surface 212, and the first upper surface 111 and the second upper surface 211 have a smooth transition. It can be understood by those skilled in the art that a smooth transition refers to a continuous linear transition without the presence of sudden changes such as steps. It can also be understood by those skilled in the art that in actual processing and assembly, errors are inevitable, but such errors should be considered as a smooth transition. In the embodiment of the present application, through the smooth transition of the first upper surface 111 and the second upper surface 211, when the flame tail flame passes through the joint of the first upper surface 111 and the second upper surface 211, the tail flame can be smoothly guided, avoiding the situation where the tail flame gathers at the joint. The guiding effect of the rocket tail flame is guaranteed.

[0030] Please continue to refer to Figure 3 and Figure 4In some embodiments, a first mounting groove 130 is provided on a side of the first side surface 112 close to the first upper surface 111, and the first thermal insulation pad 120 extends to and covers the first mounting groove 130; a second mounting groove 230 is provided on a side of the second side surface 212 close to the second upper surface 211, and the second thermal insulation pad 220 extends to and covers the second mounting groove 230. It can be understood by those skilled in the art that during the launch of a rocket, the impact of the rocket tail flame is very strong. Therefore, under the impact of the rocket tail flame, the first thermal insulation pad 120 and the second thermal insulation pad 220 may be impacted by the flame tail flame on the first glass substrate 110 and the second glass substrate 210. To avoid this phenomenon, in an embodiment of the present application, the first thermal insulation pad 120 is extended from the first upper surface 111 to the first side surface 112, and the second thermal insulation pad 220 is extended from the second upper surface 211 to the second side surface 212. In this way, when the first side surface 112 and the second side surface 212 are in contact with each other, the portion of the first thermal insulation pad 120 extending to the first side surface 112 is squeezed by the second side surface 212, and the portion of the second thermal insulation pad 220 extending to the second side surface 212 is squeezed by the first side surface 112. In this way, the peeling strength between the first thermal insulation pad 120 and the second thermal insulation pad 220 can be increased, and the first thermal insulation pad 120 and the second thermal insulation pad 220 can be prevented from being peeled off by the impact of the rocket's tail flame, thereby avoiding damage to the first substrate 110 and the second substrate 210 and increasing the cycle life of the first substrate 110 and the second substrate 210.

[0031] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the thickness of the first thermal insulation pad 120 and the second thermal insulation pad 220 is 10 mm to 50 mm. For example, it can be 10 mm, 20 mm, 30 mm, 40 mm or 50 mm, etc. It can be understood by those skilled in the art that the specific thickness of the first thermal insulation pad 120 and the second thermal insulation pad 220 can be set by those skilled in the art according to different types of rockets. For example, if the rocket tail flame is enlarged, the thickness of the first thermal insulation pad 120 and the second thermal insulation pad 220 can be appropriately larger, otherwise it can be smaller. The specific thickness selection of the first thermal insulation pad 120 and the second thermal insulation pad 220 is not specifically limited by the embodiment of the present application. Of course, it can also be understood by those skilled in the art that, in general, the thickness of the first thermal insulation pad 120 and the second thermal insulation pad 220 can be set to be the same.

[0032] Please continue to refer to Figure 3 and Figure 4In some embodiments, the surface of the first thermal insulation pad 120 located in the first mounting groove 130 facing the second component 200 is flush with the first side surface; the surface of the second thermal insulation pad 220 located in the second mounting groove 230 facing the first component 100 is flush with the second side surface. In the embodiment of the present application, the first mounting groove 130 is set on the first side surface 112, and the first thermal insulation pad 120 is partially located in the first mounting groove 130. By setting it in this way, after the first thermal insulation pad 120 is located in the first mounting groove 130, the surface of the first thermal insulation pad 120 facing away from the first mounting groove 130 is flush with the first side surface 112, so that it can be ensured that there is no gap when the first side surface 112 and the second side surface 212 are attached, so as to ensure that the first upper surface 111 and the second upper surface 211 can be smoothly transitioned. The effect of setting the second mounting groove 230 on the second side surface 212 can refer to the effect of setting the first mounting groove 130 on the first side surface 112, which will not be repeated here.

[0033] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the combined deflector further includes a locating pin 300, the first side surface 112 is further provided with a first locating portion, the second side surface is provided with a second locating portion, a portion of the locating pin 300 is located in the first locating portion, and another portion of the locating pin 300 is located in the second locating portion.

Of course, it will also be appreciated by those skilled in the art that the locating pin 300 may also be preset on the first locating surface or the second locating surface, for example. The first locating portion is a stud, and the locating pin 300 includes a threaded hole section, such as Figure 5 As shown, the locating pin 300 is preset on the first side surface 112 by screwing the threaded hole section and the stud. Obviously, the same method can also be used to preset on the second side surface 212, and the first positioning portion can also be set as a threaded hole, and the locating pin 300 includes an external threaded section and other methods for preset, which will not be repeated here. Furthermore, the number of locating pins 300 can be multiple, such as two, three or four, etc., so as to increase the positioning ability. It should be noted that, under normal circumstances, the number of locating pins 300 should not be less than two. By providing the locating pin 300, the docking between the first docking surface and the second docking surface can be facilitated, thereby further ensuring a smooth transition between the first upper surface 111 and the second upper surface 211.

The first mounting portion 140 can be a boss protruding on the side of the first side surface 112 away from the first upper surface 111, and the second mounting portion 240 can be a groove provided on the second side surface 212. Obviously, the positions of the boss and the groove need to correspond. A stud is provided on the boss as the first positioning portion, and a round hole is provided in the groove as the second positioning portion, and the threaded hole section of the positioning pin 300 is screwed to the stud of the boss, so that the positioning pin 300 is preset to the first side surface 112.

Specifically, the first connecting portion 150 and the second connecting portion 250 can both be plate-shaped, and the first connecting portion 150 and the second connecting portion 250 are correspondingly provided with through holes for fastening. It can also be understood that the number of the first connecting portions 150 is two, and the two first connecting portions 150 are respectively fixed on the opposite sides of the first side surface 112.
