[0002] At present, as a common loading device, a light gas gun is widely used in high-speed and super-high-speed impact experiments. However, various requirements may be generated in experiments, which leads to the fact that projectiles or fragments to be launched in impact experiments have different specifications, and in the impact test, the speed of the projectile is generally high, which can reach more than 6-7 km / s. The high-speed movement of the projectile in the barrel can easily cause serious damage to the launch tube. Therefore, a projectile carrier needs to be used to cooperate with the launch of the projectile during the launch of the projectile, and the projectile carrier and the projectile need to be completely separated before hitting the target, so as to ensure the accuracy and effectiveness of the experiment.

[0003] The existing projectile carrier launches the projectile by making the axis of the projectile coincide with the trajectory, and cannot realize the launch of the projectile according to the set roll angle. Therefore, the related experiment cannot be realized by the existing experimental method, and accurate and effective experimental data cannot be obtained. In addition, the existing projectile separation technology mainly realizes the separation of the projectile carrier and the projectile by impacting the projectile carrier with a separator. The projectile carrier produces an uncertain constraint on the projectile. Under the constraint, the separation of the projectile carrier and the projectile is affected, which leads to the inaccuracy of the experimental results, and the success rate of the experiment is also affected. SUMMARY

[0004] The present application aims to provide a launch self-separation projectile carrier capable of defining the roll angle of a projectile, solve the problem that the existing projectile carrier cannot realize the launch of the projectile according to the set angle, avoid the influence of the separation of the projectile carrier on the trajectory of the projectile, avoid the collection of a large number of high-speed impact conditions of the projectile through multiple experiments, ensure that the experiment can reflect the real damage condition of high-speed impact, improve the accuracy of experimental data, and provide an assembling method thereof.

And the support spring is placed in the set support spring positioning slot, while ensuring that the thrust of the support spring can be applied to the center of mass position of the elastic body.

[0031] The present application will be further illustrated below in combination with the drawings and specific embodiments, and it should be understood that these embodiments are only used to illustrate the present application and not to limit the scope of the present application.

[0032] A launch self-separation support capable of defining the rolling angle of a projectile, as shown in the figure, comprises a support body 1 and a launch tube 2 for placing the support body 1. Figs. 1-7

[0033] ​The elastic support body 1 comprises a left lobe 1-1, a right lobe 1-2, a support spring 4 and a separation spring 5, wherein the support spring 4 and the separation spring 5 are both helical springs.

[0034] The left lobe 1-1 and the right lobe 1-2 are of the same structure and are mirror-imaged, and the separation spring 5 is provided between the left lobe 1-1 and the right lobe 1-2. In one embodiment, the separation spring 5 is provided in three numbers and is arranged in a triangular shape between the left lobe 1-1 and the right lobe 1-2. The left lobe 1-1 and the right lobe 1-2 are arranged in close contact in the launching tube 2, and the outer wall surfaces of the left lobe 1-1 and the right lobe 1-2 are in abutment with the inner wall surface of the launching tube 2. The abutment surfaces of the left lobe 1-1 and the right lobe 1-2 are tooth surfaces in meshing engagement. The tooth surface of the left lobe 1-1 is provided with a plurality of left lobe separation spring placing grooves 1-1-1 at intervals, and the tooth surface of the right lobe 1-2 is provided with a plurality of right lobe separation spring placing grooves 1-2-1 at corresponding intervals. One end of the separation spring 5 is arranged in the left lobe separation spring placing groove 1-1-1, and the other end is arranged in the right lobe separation spring placing groove 1-2-1. When the left lobe 1-1 and the right lobe 1-2 are in close contact, each left lobe separation spring placing groove 1-1-1 is in abutment with a corresponding right lobe separation spring placing groove 1-2-1, so that the separation spring 5 between them is in a compressed state.

[0035] The left lobe 1-1 and the right lobe 1-2 form a columnar structure with a conical frustum-shaped head. An elastic body placing cavity for mounting the elastic body 3 is formed on the head end surface of the columnar structure in the axial direction. The central part of the head of the left lobe 1-1 is provided with a left lobe elastic body placing cavity 1-1-5, and the central part of the head of the right lobe 1-2 is provided with a right lobe elastic body placing cavity 1-2-5. The left lobe elastic body placing cavity 1-1-5 and the right lobe elastic body placing cavity 1-2-5 are in abutment to form the elastic body placing cavity, which is a cylindrical cavity.

[0036] A circle of support spring positioning grooves is formed on the inner bottom surface of the elastic body placing cavity. The inner bottom surface of the left lobe elastic body placing cavity 1-1-5 is provided with a plurality of left lobe support spring positioning grooves 1-1-4 at intervals, and the inner bottom surface of the right lobe elastic body placing cavity 1-2-5 is provided with a plurality of right lobe support spring positioning grooves 1-2-4 at intervals. The left lobe elastic body placing cavity 1-1-5 and the right lobe elastic body placing cavity 1-2-5 are in abutment to form a cylindrical elastic body placing cavity, so that the plurality of left lobe support spring positioning grooves 1-1-4 and the plurality of right lobe support spring positioning grooves 1-2-4 are combined to form a circle of support spring positioning grooves for arranging the support spring 4. According to the required tumbling angle, the support spring 4 is arranged in one of the support spring positioning grooves. When the elastic body 3 is arranged in the elastic body placing cavity, the left lobe 1-1 and the right lobe 1-2 clamp the elastic body 3, the elastic body 3 is in abutment with the inner bottom surface of the elastic body placing cavity and compresses the support spring 4 to make it in a compressed state, and the head of the elastic body 3 protrudes out of the elastic body placing cavity.

[0037] The angle between two adjacent support spring positioning grooves is 30°, and the total number of the support spring positioning grooves is 12.

[0038] The assembly method of the above-mentioned projectile with definable rolling angle from the separate projectile carrier includes the following steps:

[0039] Step 1: Place the plurality of separate springs in the right-limb separate spring placing groove provided in the right limb of the projectile carrier, and combine the right limb with the left limb of the projectile carrier to form the whole projectile carrier.

[0040] Step 2: Select the appropriate support spring, adjust the stress degree and placing position of the spring according to the experimental needs, until the projectile can be launched at the set arbitrary rolling angle, place the fragments or projectiles in the projectile placing cavity at the head of the projectile carrier, and at this time the support spring should be in a compressed state.

[0041] Step 3: Place the projectile carrier in the launch tube, and the outer peripheral wall of the projectile carrier should be tightly fitted with the inner peripheral wall of the barrel.

[0042] Step 4: After installing the projectile carrier into the barrel, activate the light gas gun.

[0043] Due to the presence of high-pressure hydrogen gas in the light gas gun, when launched, the high-pressure hydrogen gas will act on the bottom push surface of the separate projectile carrier, giving the projectile carrier a force to promote its forward movement and maintain a high speed. The projectile carrier flies along the barrel, and when it moves to the outside of the launch tube, the projectile carrier no longer receives a support force from the inner wall of the launch tube, and the separate spring provided in the projectile carrier will also provide a force to promote the separation of the left and right limbs of the projectile carrier. During the separation process, the trajectory of the projectile will not be affected. Due to the placement of the support spring under the projectile and the design of the position and adjustment of the pre-stress or stretching degree of the support spring, the projectile will generate an initial angular velocity, causing it to start rolling, thereby achieving the launch of the projectile at an arbitrary angle.
