Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultra-high-speed collision loading test, in particular to a launching projectile carrier for irregular projectile self-defined rolling angle and an assembling method thereof. BACKGROUND

[0002] Current ultra-high-speed impact damage test is mainly carried out by light gas gun, but in the experiment, the caliber of the light gas gun cannot be adjusted, which leads to the experiment needing to use a projectile carrier matched with the inner diameter of the light gas gun. The projectile carrier is used to cooperate with the projectile to accelerate in the barrel of the light gas gun to complete the loading test. However, the previous projectile carrier is single in form and only suitable for regular-shaped projectiles due to the need for separation, which limits the selection of projectile shape and cannot meet the actual situation of different shapes of explosive projectile fragments. In addition, since the high-speed impact in the actual explosion and space debris environment is generated from different directions, the existing projectile carrier can only launch the projectile in a fixed direction, which cannot meet the actual situation of explosive projectiles and space debris generated from different directions.

[0003] At present, the existing projectile carrier is used to control the trajectory of the projectile by aligning the axis of the projectile with the trajectory, which cannot realize the launching of the projectile at the required rolling angle, so the existing experimental method cannot realize the related experiment, and thus the accuracy of the conclusion cannot be obtained. Even if a large number of experiments are carried out to simulate the high-speed impact of a large number of fragments, the real damage situation of high-speed fragments cannot be reflected, and the accuracy of the experimental data is seriously affected. In addition, a large number of experiments will cause waste of manpower and material resources, and there are disadvantages of poor economy and low timeliness. SUMMARY

[0004] The present application aims to solve the above problems, and provides a launching projectile carrier for irregular projectile self-defined rolling angle, which can solve the problem that the existing projectile carrier cannot launch irregular projectiles and cannot be launched at the set angle, avoid the adverse effects of projectile separation on the trajectory of the projectile, and does not need a large number of experiments to simulate the high-speed impact of the projectile, improve the feasibility of the experiment, and ensure the accuracy of the experimental data. And provides an assembling method thereof.

[0005] Technical solution: A launching projectile holder for irregular projectile body self-defined rolling angle, comprising a holder body and a holder separator used in conjunction therewith, the holder body comprising an upper shell, a lower shell, positioning columns and a lever rod, the upper shell and the lower shell being coaxially screwed at the end portions, forming a cavity with one end closed and the other end open, the projectile body being placed in the middle of the cavity, the positioning columns filling the remaining space in the cavity and supporting the projectile body, the lever rod comprising a lifting rod, a flat plate lever and a support column, the flat plate lever being horizontally arranged on the end face of the lower shell, the lifting rod being arranged in the upper shell along the axial direction, one end of the lifting rod being in contact with one end of the flat plate lever, the other end of the lifting rod extending out of the head of the upper shell, the support column being arranged in the lower shell along the axial direction, one end of the support column being in contact with the other end of the flat plate lever.

[0006] When the high-pressure hydrogen gas in the light gas gun directly acts on the bottom pushing surface of the holder, the holder is pushed to move forward at high speed. When the projectile placement cavity segment moves to the position of the holder separator, the lever rod will collide with the holder separator, providing a force to the lifting rod in the lever rod, which will be transmitted through the flat plate lever, causing the support column in the lower shell to move in the direction of the projectile launching, so that the projectile can be provided with a corresponding thrust according to the set angle to make the projectile roll according to the set angle and hit the target. At the same time, the holder is limited by the holder separator and clamped in the holder separator, so it will not be ejected with the projectile.

[0007] Further, the upper shell is a cylindrical structure with a conical frustum-shaped head, and a through positioning column placement cavity is arranged in the middle of the upper shell along the axial direction. A plurality of through lifting rod positioning grooves are also arranged on the upper shell along the axial direction, the lifting rod positioning grooves being evenly distributed along the outer side of the positioning column placement cavity in a circumferential direction. The lifting rod is arranged in the lifting rod positioning groove.

[0008] Optimally, the positioning columns are arranged in multiple rings from the center to the outside in the positioning column placement cavity, and each ring of the positioning columns is arranged in a circular ring shape.

[0009] The positioning column placement cavity is arranged in the head of the upper shell, and the positioning columns are distributed in a circular ring shape in the positioning column placement cavity. According to the shape of the projectile body, the corresponding positioning columns are taken out of the positioning column placement cavity and the projectile body is placed at the position where the positioning columns are taken out. Thus, the requirement of placing different shaped projectile bodies can be met. Through the design and control of the positioning columns, different shaped projectile bodies can be adapted and the projectile body can be positioned during clamping.

[0010] The shape of the projectile placement cavity is determined according to the shape of the projectile body. By taking out the corresponding positioning columns below the projectile body, the remaining positioning columns will play a positioning role for the projectile body.

[0011] Further, the lower half body is cylindrical, and a boss is arranged at the center of the connecting end face of the lower half body, an outer thread for connecting with the upper half body is arranged on the outer circumferential surface of the boss, and a plurality of support column placement grooves penetrating the boss in the axial direction are arranged at intervals on the boss, a plurality of flat lever positioning grooves are arranged at intervals in the radial direction on the end face of the lower half body, the flat lever positioning grooves extend to the bottom surface of the boss, the support column placement grooves are in communication with the flat lever positioning grooves, the flat lever is arranged in the flat lever positioning groove, and the support column is arranged in the support column placement groove and abuts against one end of the flat lever.

[0012] Preferably, a downward extending groove is further arranged on the inner bottom surface of the end of the flat lever positioning groove away from the boss.

[0013] The extending groove can ensure that the lifting rod in the upper half body moves in the opposite direction of the ejection of the projectile when colliding with the ejector separator, and through the support of the flat lever, a force is provided to the support column in the lower half body, so that the support column below the projectile moves in the ejection direction of the projectile, thereby achieving the provision of a corresponding thrust to the projectile at a set angle to make the projectile roll at a set angle and hit the target.

[0014] Further, a ball is arranged at the middle of the flat lever as a fulcrum, which can better meet the needs of the lever.

[0015] Further, the positioning column is a columnar structure with a gradually decreasing diameter from one end to the other end, the large end is a flat end, and the small end is a circular arc curved end, and the large end faces the lower half body.

[0016] The positioning column has a structure of being narrow at the top and wide at the bottom, which can ensure that the upper half body can limit the positioning column during the separation of the projectile and the ejector, so that the positioning column does not follow the ejection of the projectile.

[0017] Preferably, the lever rod has at least one.

[0018] During the ejection of the projectile, the ejector moves forward, and when it moves to the ejector separator, the impact will generate a force on the lifting rod, which will act on the projectile through the support column, and the projectile will generate an initial angular velocity during ejection, so that it starts to roll, thereby achieving ejection at a set arbitrary rolling angle. The number of lever rods is set according to the needs of the experiment, and the number of lever rods is selected and the placement position of the lever rod is adjusted according to different experiments until the projectile can be ejected at a set rolling angle.

[0022] Step three: threadedly connect the upper half body and the lower half body into an elastic support body, and insert the pull rod into the corresponding position of the upper half body;

[0023] Step four: place the elastic support body on the inner wall of the launch tube, and ensure that the direction of the elastic support body is consistent with the direction of the high-pressure hydrogen gas acting on the light gas gun;

[0024] Step five: install the elastic support separator in the impact cabin and clamp the cabin wall;

[0025] Step six: complete the installation of the elastic support in the launch tube, and trigger the light gas gun, so that the elastic body and the elastic support are separated during the movement, and the elastic body rolls according to the set angle.

In the initial state, the positioning column placement cavity 2-1-1 is filled with positioning columns 3, the shell body is placed in the upper shell body 2-1, the shell body extrudes the positioning columns 3, the corresponding positioning columns 3 below the shell body are removed, thereby forming a shell body placement cavity 2-1-4, and the remaining positioning columns 3 support and position the shell body. According to the shape of the shell body, the corresponding positioning columns 3 are removed, the remaining positioning columns 3 can position the shell body, and the shape of the shell body placement cavity 2-1-4 formed is determined according to the shape of the shell body placed in the front part of the upper shell body 2-1. ​

[0044] The lever rod 5 comprises a pull rod 5-1, a flat plate lever 5-2 and a support column 5-3.

[0045] A plurality of support column placement grooves 2-2-1 are provided on the boss in an axial direction. A plurality of flat plate lever positioning grooves 2-2-2 are provided on the end face of the lower half body 2-2 in a circumferential direction of the boss. The flat plate lever positioning grooves 2-2-2 extend to the bottom surface of the boss, so that the support column placement grooves 2-2-1 are communicated with the flat plate lever positioning grooves 2-2-2. The flat plate lever 5-2 is arranged in the flat plate lever positioning groove 2-2-2, and the support column 5-3 is arranged in the support column placement groove 2-2-1 and abuts one end of the flat plate lever 5-2.

[0046] A plurality of through pull rod positioning grooves 2-1-2 are provided on the upper half body 2-1 in an axial direction. The pull rod positioning grooves 2-1-2 are arranged in a circumferential direction along the outer side of the positioning column placement cavity 2-1-1. The pull rod 5-1 is arranged in the pull rod positioning groove 2-1-2. One end of the pull rod 5-1 is in contact with one end of the flat plate lever 5-2, and the other end extends out of the head of the upper half body 2-1.

[0047] An inner bottom surface of an end of the flat plate lever positioning groove 2-2-2 away from the boss is further provided with a downward extension groove. A middle part of the flat plate lever 5-2 is provided with a ball as a fulcrum.

[0049] The pull rod 5-1, the flat plate lever 5-2 and the support column 5-3 form a U-shaped structure. The length of the pull rod 5-1 is greater than the length of the support column 5-3, and the lever principle is used for design.

[0050] The upper half body 2-1 and the lower half body 2-2 are connected by a threaded manner to form a whole which is placed in a launch tube. The outer peripheral walls of the two are respectively in abutment with the inner wall of the launch tube. The cartridge body 2 moves to the cartridge separator 1 in the barrel to realize the separation of the projectile body and the cartridge body 2.

[0051] When the projectile bodies of various shapes are placed in the projectile placement cavity, the remaining positioning columns can realize a good positioning of the projectile bodies according to the shapes of the projectile bodies and fix the projectile bodies.

[0055] Step three: Assemble the upper and lower petals into a whole through threads, and place the pull rod in the pull rod positioning slot.

[0056] Step four: Install the projectile holder separator in the impact cabin and clamp the cabin wall.

[0057] Step five: After installing the projectile holder into the barrel, fire the light gas gun.

[0058] There is high-pressure hydrogen gas inside the barrel. When the high-pressure hydrogen gas is released, a force will be generated on the bottom push surface of the projectile holder, prompting the projectile holder to move forward along the direction of high-pressure hydrogen gas release and maintain a high running speed. The projectile holder moves along the barrel and moves to the projectile holder separator, where the projectile holder will collide with the projectile holder separator. At this time, the upper petal lever rod will be forced in the opposite direction under the impact of the projectile holder separator, thereby pushing the lower petal lever rod to move in the direction of the projectile launch, providing a thrust to the projectile at a set angle, allowing the projectile to be launched with a roll at a set angle, and the launch angle can also be controlled.
