[0002] Mortar dummy rounds are training equipment used to simulate the effects of live mortar firing. They are primarily used for gunner training, allowing soldiers to become familiar with the mortar loading and firing processes. In actual use, mortar dummy rounds usually require the following techniques:
[0003] 1. Shell, simulating the shape and size of real shells;
[0004] 2. Tail fins, to ensure the missile maintains a stable attitude during flight;
[0005] 3. Fuze, which triggers some specific effects after the simulated projectile is launched;
[0006] 4. A driving assembly, used to propel the simulated projectile inside the barrel;
[0007] The fuze of a training round is usually a simulated device that does not trigger an explosion. It may just be a component that looks similar to a live round fuze and is used to train soldiers on how to identify and operate the fuze. Compared to live rounds, dummy rounds are cheaper to manufacture and can be used in large quantities, reducing training costs.
[0008] The shell and tail tube of the simulated projectile are fixedly connected, and the tail fin is fixedly connected to the barrel. The size of the tail fin is fixed, and the trajectory of the simulated projectile is not much different each time it is launched. During training, it is impossible to intuitively understand the impact of the tail fin on the dispersion range of the projectile, which has certain limitations in teaching and training.

[0025] The embodiment of the present application effectively solves the problem of fixed connection between the tail fin and the barrel by providing a simulated bullet for mortar training.

During training, it is not possible to intuitively understand the impact of the tail fin on the dispersion range of the bullet. During teaching and training, there are certain limitations. By rotating the shaft, the shaft is rotated at the top of the tail fin body. When adjusting multiple adjustment plates through the scale bar, multiple adjustment plates can be made to slide the same distance.

During the launch process, the changes in the muzzle velocity and angle of the simulated bullet under different tail fin body areas can be observed, thereby improving operating skills and accuracy.
[0026] Example
[0027] like Figure 1 - Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the problem of fixed connection between the tail fin and the gun barrel. The size of the tail fin is fixed, and the trajectory of the simulated projectile is not much different each time it is fired. During training, it is not possible to intuitively understand the impact of the tail fin on the dispersion range of the projectile. During teaching and training, there are certain technical limitations. The overall idea is as follows:
[0028] In response to the problems existing in the prior art, the utility model provides a simulation projectile for mortar training, comprising a projectile shell 11, a tail pipe 12 is provided at the side end of the projectile shell 11, a fixing ring 14 is fixedly installed at the end of the tail pipe 12, at least two tail wing bodies 15 are fixedly installed on the surface of the fixing ring 14, and an adjustment plate 21 is slidably installed on the side end of each tail wing body 15, and at least two scale bars 22 are fixedly installed on the top of each adjustment plate 21. One end of the adjustment plate 21 is a raised conical design. When adjusting multiple adjustment plates 21 through the scale bar 22, multiple adjustment plates 21 can be allowed to slide the same distance. At the same time, by adjusting the positions of the two adjustment plates 21, the overall area of the tail wing body 15 is increased. By adjusting the area of the tail wing body 15, the influence of the tail pipe 12 on the flight stability of the projectile can be intuitively demonstrated.
[0029] Two driving rods 19 are rotatably installed inside each tail wing body 15, and a rotating shaft 18 is rotatably installed on the top of each tail wing body 15. A mounting ring 13 is rotatably installed on the surface of the tail pipe 12, and two positioning plates 16 are fixedly installed on the side ends of the mounting ring 13. Two mounting buttons 17 are slidably installed on the outside of each positioning plate 16. The side ends of the projectile shell 11 are provided with docking grooves, and the top of the projectile shell 11 is provided with a fuse. Two exhaust ports are provided on the surface of the tail pipe 12, and a first cavity is provided inside the tail pipe 12. The first cavity is a cylindrical cavity. A hollow driving member is slidably installed inside the tail pipe 12, and an empty powder tube is provided at the end of the hollow driving member. The gas expands inside the tail pipe 12, so that the space between the front end of the hollow driving member and the front end of the first cavity increases, thereby driving the hollow driving member to move relative to each other in the first cavity, and the expanded gas drives the simulated ejection out of the muzzle.
[0030] Working principle:
[0031] In the first step, a first cavity is opened inside the tail pipe 12, and the first cavity is a cylindrical cavity. A hollow driving member is slidably installed inside the tail pipe 12, and a blank cartridge tube is provided at the end of the hollow driving member. The blank cartridge tube is loaded at the rear end of the hollow driving member, and the simulated ejection is ejected out of the muzzle through the blank cartridge tube, and sound and light are emitted. The gas expands inside the tail pipe 12, so that the space between the front end of the hollow driving member and the front end of the first cavity is increased, thereby driving the hollow driving member to do relative movement in the first cavity, generating a "boat-supporting" effect, and driving the simulated ejection out of the muzzle.
[0032] By rotating the mounting ring 13, the mounting ring 13 drives the positioning plate 16 to rotate inside the docking groove at the side end of the projectile shell 11. The positioning plate 16 is an arc-shaped design, and the outer side of the positioning plate 16 is a convex design, which is engaged with the inner part of the docking groove. At the same time, the movement of the positioning plate 16 drives the two mounting spring buttons 17 to move. The mounting spring button 17 is a retractable structure. The squeezed mounting spring button 17 is retracted into the interior of the positioning plate 16. By rotating the mounting ring 13, the mounting ring 13 drives the positioning plate 16 to deflect at the side end of the projectile shell 11, and the positioning plate 16 is matched with the opening of the docking groove. The tail pipe 12 is pulled, and the tail pipe 12 drives the mounting ring 13 to move, and the positioning plate 16 is pulled out of the side end of the projectile shell 11. The projectile shell 11 and the tail pipe 12 are designed to be split, which is convenient for maintenance and replacement.
[0033] The second step is to rotate the shaft 18 so that the shaft 18 rotates at the top of the tail body 15. The end of the shaft 18 is docked with the two drive rods 19, and the bevel gear installed at the end of the shaft 18 is connected to the drive rod 19 to drive the two drive rods 19 to rotate inside the tail body 15. At the same time, the surface of the drive rod 19 is a threaded design, and the top of the drive rod 19 is engaged with the adjustment plate 21. The two drive rods 19 simultaneously push the adjustment plate 21 to slide on the side end of the tail body 15. At the same time, a scale bar 22 is installed on the top of the adjustment plate 21. The top of the adjustment plate 21 drives multiple scale bars 22 to move, and the scale bars 22 are used to adjust the multiple adjustment plates 21. When making adjustments, multiple adjustment plates 21 can be allowed to slide the same distance. At the same time, by adjusting the positions of the two adjustment plates 21, the overall area of the tail wing body 15 can be increased. By adjusting the area of the tail wing body 15, the influence of the tail tube 12 on the flight stability of the projectile can be intuitively demonstrated. When the area of the tail tube 12 increases, it can be observed that the simulated projectile is more stable in flight, and the shaking and swing amplitudes are reduced; conversely, when the tail area decreases, the stability of the simulated projectile decreases, and the launch trajectory will change. During the launch process, the changes in the muzzle velocity and angle of the simulated projectile under different tail wing body 15 areas can be observed, thereby improving operating skills and accuracy.
[0034] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
