Description

Technical Field

[0001] The invention belongs to the technical field of artillery firing, and in particular relates to an electrically controlled firing artillery with a stepless adjustable range. Background Art

[0002] Improving the range and power of barreled weapons has long been a hot topic for researchers worldwide. Muzzle velocity is the most direct factor affecting range and power, and increasing projectile velocity essentially increases the propellant's ability to work on the projectile. As the primary energy source for barreled weapons, researchers both domestically and internationally are constantly exploring how to utilize new technologies and energy sources to improve propellant performance, thereby increasing range and power.

[0003] Electronically controlled propellant is a new type of gunpowder whose burning rate changes with the voltage applied to the charge. This coupled physical-chemical system overcomes the uncontrollable combustion drawbacks of traditional single-chemical propellant systems. By adjusting the burning rate through external electrical energy input, the gun's muzzle velocity and range can be adjusted.

[0004] Traditional variable-burning-rate propellants achieve variations in burning rate by introducing insensitive materials or modifying the charge structure. However, this variation cannot be dynamically adjusted and reduces the energy density of the propellant. Compared to traditional variable-burning-rate propellants, electronically controlled propellants can adjust the burning rate in real time through voltage without the need for insensitive materials. Furthermore, they eliminate the need for ignition powder, effectively increasing the charge's energy density. Modular charges achieve graded range control by varying the total charge energy. Compared to modular charges, electronically controlled propellants can achieve stepless range control.

[0005] Traditional propellants do not require the continuous action of positive and negative poles, and their charge structure is completely different from that of electronically controlled propellants. Traditional artillery firing does not require the continuous action of an external electrical power unit. The lack of mutual insulation between the components of traditional artillery makes it impossible to use electronically controlled propellants. Existing artillery systems cannot use electronically controlled propellants as the main charge. Summary of the Invention

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 A range-adjustable, electronically controlled cannon using an electronically controlled propellant as its primary charge is characterized by comprising a main gun body 1, two types of electronically controlled propellants 2, and a breech block 3. The electronically controlled propellants include end-face and coaxial types. In the end-face type, the positive metal mesh 12 is connected to the positive external electrode 8 via the positive electrode 4 and to the breech block positive electrode 22 via the positive external conductive ring 11. The breech block positive electrode is divided into two parts, connected in the middle by a positive spring 23, with a margin to ensure close contact with both the positive external electrode 8 and the positive electrode 24 of the electric power unit. The negative electrode 15 is connected to an insulating ring 16 and to the negative external electrode 7 via a compression spring 14. The compression spring 14 ensures dynamic contact between the propellant and both the positive and negative electrodes, and further connects to the breech block negative electrode 25. The breech block negative electrode is divided into two parts, connected in the middle by a negative spring 26, with a margin to ensure close contact with both the positive external electrode 8 and the negative electrode 27 of the electric power unit. The charge 13 is located between the two poles, and the adjusting nut 9 and the insulating base 6 ensure that all parts are in close contact. In particular, the area, number and arrangement of the positive electrode metal mesh will affect the combustion process of the propellant. The difference from the coaxial type is that the negative electrode is a plurality of negative electrodes 20, which are directly connected to the negative electrode outer electrode 7. The multiple negative electrodes are evenly distributed in the charge 13. The shape, size, density and arrangement of the negative electrode will affect the combustion process of the propellant. The pressure plate 5, the insulating sleeve 19, the insulating gasket 10 and the insulating glue 21 ensure the insulation of the relevant parts. The air-tight ring 28 is used to fix the warhead to ensure that the warhead begins to separate from the charge only after the pressure inside the bullet exceeds the threshold. In addition, it also includes a cartridge case 17 and a warhead 18.

[0032] The main charge of an electrically controlled gun uses an electrically controlled propellant. A closed gas ring regulates the pressure threshold for separation between the projectile and the charge. No ignition charge is required. A cooperating electric power unit provides power. The charge maintains dynamic contact with the positive and negative electrodes via a compression spring, or multiple electrodes are distributed within the charge. The positive and negative electrodes of the electric power unit are inserted into the rear end of the breech block and connected to the positive and negative electrodes.

[0033] The present invention uses mechanical processing to process the various parts and then assemble them. For an end-face electrically controlled projectile, the insulating sleeve 19, positive electrode 4, insulating gasket 10, negative electrode outer electrode 7, compression spring 14, negative electrode 15, and insulating ring 16 are assembled in sequence. The propellant charge 13 is loaded, the positive electrode metal mesh 12 is inserted, and the adjusting nut 9 is tightened. The above assembly is assembled with the cartridge case 17 and bullet 18, and the pressure plate 5 and insulating base 6 are assembled. For a coaxial electrically controlled projectile, the propellant is then injected between the assembled positive electrode 4 and the multiple negative electrodes 20, forming the propellant therein. The assembled electrically controlled projectile is then loaded into the gun barrel and connected to the breech block 3. The positive electrode outer conductive ring 11 is sequentially connected to the breech block positive electrode 22 and positive electrode spring 23; the negative electrode outer electrode 7 is sequentially connected to the breech block negative electrode 23 and negative electrode spring 24. The breech block electrode has a margin, and when there is a gap between the base of the electric-controlled launcher and the breech block, the spring pushes the breech block electrode to make close contact with the base of the electric-controlled launcher. Connect the positive electrode 24 and the negative electrode 27 of the external power supply unit.
