Example Embodiment
[0027] Example 1
[0028] This embodiment is an embodiment of the elastic carrier structure.
[0029] please combine Figure 2 to Figure 4 As shown, the present invention discloses a stable propelling cartridge holder for an air cannon, which is applied in the air cannon and carries projectiles. The elastic support includes a cylindrical elastic support body, and at least one annular groove is arranged on the outer surface of the elastic support body, and the annular groove is circumferentially arranged on the elastic support body.
[0030] The specific description is, as figure 2 , there are three annular grooves 2 parallel to each other and evenly arranged on the spring holder body 1 , and the width and depth of the three annular grooves 2 are the same. The cradle structure is numbered as structure B in this embodiment. like image 3 , there are four annular grooves parallel to each other on the receptacle body 1 ′, and two annular grooves 21 ′ have the same width and ...
Example Embodiment
[0032] Embodiment 2
[0033] This embodiment is an embodiment of the design method of the ejector structure.
[0034] please combine Image 6 As shown in the present invention, the design method of the stable propelling susceptor for the air gun in the present invention comprises the following steps:
[0035] (1) Given the initial design parameters, design several types of elastic supports, and the number of grooves and groove widths on each elastic support are different;
[0036] (2) Through the analysis, modeling, calculation and analysis of the gap leakage of several different types of elastic supports, the leakage of different elastic supports is obtained;
[0037] (3) Comparing the leakage of each type of magazine, the type of magazine with the smallest leakage is used as the initial design configuration;
[0038] (4), set the leakage index of the spring carrier of the initial design configuration as the initial target parameter for further iteration;
[0039] (5) Giv...
