る。In addition, research has been conducted to automatically supply a bullet and a propellant charge to a gun with a mechanical device for the purpose of improving the shooting speed of the gun and reducing the number of operators who operate the gun.
A propellant charge suitable for this purpose is a modular propellant charge composed of a plurality of basic units. A modularized propellant charge is prepared by connecting a plurality of modules required for shooting at the maximum firing distance in advance, and is mechanically separated into a number of modules corresponding to the target firing distance at the time of firing and loaded. Is what you do. A burnable container is indispensable for making this modular propellant charge, and there is a problem in how to make it connectable. Regarding the connection method of the burnout container, Japanese Patent Application Laid-Open No. 2-500772 discloses that
As shown in FIG. 7, connecting the modularized propellants 71 and 72 by using a plug-type connecting member 73 is disclosed in Japanese Patent Application Laid-Open No. 4-347500. Connecting parts 8 to the propellant charges 81 and 82, respectively.
By disposing 5,86, an invention is disclosed in which modules are integrated in a medicine chamber and simultaneous ignition is enabled.

Since kraft pulp and synthetic resin are used as the main raw materials, they are more fragile than metal materials, and their dimensions are easily affected by changes in climate such as humidity and the environment, and strictly control the manufacturing environment and the time of the manufacturing process. Even so, it is very difficult to increase the dimensional accuracy. In the method of connecting the modularized propellant charge by using the above-described plug-type connecting member or by providing a connecting portion at one end of the burnout container, the connecting force of the connecting portion is smaller than that of the ring-shaped female portion. Since it is determined by the fitting of the male part and the frictional resistance, it is impossible to make all modules have a constant coupling force.

性容器が破壊するといった問題があった。(Separation by mechanical device) A method of mechanically separating a modular propellant charge is to press the outer periphery of the burnout container so as to be sandwiched by a saw-tooth-shaped clamp claw of the separating device.
A method of pulling out in the long axis direction is generally used. If the coupling force of the modules is not constant, the separating force of the module and the pressing force of the clamp pawl must be set so that the module having the highest coupling force can be separated. When the separation force of the module and the pressing force of the clamp claw are set to be large in this way, the burnable container is deformed and cannot be separated, or when the separation is attempted with a larger force, the burnable container is not removed. There was a problem of destruction.

となる問題があった。(Manual Handling) When the mechanical device for separating the modules breaks down, it is necessary to have the operability that the modules can be rearranged manually and supplied to the gun. Therefore, when supplying the propellant charge to the gun by manual power, it is necessary to have a binding force that does not separate the module due to the deflection of the vicinity of the center due to the weight of the propellant charge even if both ends of the connected module are supported . Further, since it is difficult to separate the connected modules by pulling them out in the long axis direction by human power, a method of applying a short axis direction force to the modules to be separated and breaking the connected parts apart has been adopted. . If the coupling force is such that it does not separate even if both ends of the connected module are supported, the coupling portion of the burnout container is deformed or broken during the aforementioned manual separation, and it is difficult to reconnect. There was a problem.

In a modularized propellant charge, there must be no unburned residue from the number of modules to obtain the maximum range to one module. Considering the separation by machine and the handling by human power, the burnout container needs to be strengthened.However, when such a strong burnout container is used with a gun, especially when used in one module, There was a problem that unburned residue occurred. SUMMARY OF THE INVENTION An object of the present invention is to provide a burnable container which can be reliably separated when a mechanical separating means is used and which can be easily handled by human power.

The thickness of the burnable case and the burnable cap is 1/1 of the outer diameter of the cylindrical portion of the burnable case.
If the value is less than 50, the strength in the case of a modularized propellant charge is poor even if the dimensional accuracy is increased, while
When the thickness exceeds 1/50, unburned residue occurs when used with a gun. It should be noted that in FIG.
A clamp groove 14 can be attached to 1 as needed. It is not necessary to provide the clamp groove 14. However, when the clamp claw of the separation device is hooked on the clamp groove, an effective structure is obtained by providing the clamp claw 14 along the circumference of the burnout case 12. The clamp groove 14 can be arranged at an arbitrary position on the outer surface of the burnable case 12. There is the advantage that it can be kept constant. In addition, the clamp groove 14 does not need to be arranged over the entire circumference along the circumference of the burnout case 12, but it is preferable that the clamp groove 14 extends over the entire circumference in order for the clamp claw to be engaged at an arbitrary position. Further, the shape of the clamp groove 14 can be made to correspond to the shape of the clamp claw, such as a semicircular or trapezoidal cross section. Further, the clamp groove 14

から適宜選ばれる。The composition of the burnout container used in the present invention is mainly composed of nitrocellulose, kraft pulp and synthetic resin. The composition of the burnout container of the present invention used for a field gun firing charge is such that nitrocellulose is 40 to 80% by weight,
5-15% synthetic resin in parts by weight, except kraft pulp and Suruga it further to 1-4 weight ratio of nitrocellulose for kraft pulp. When the ratio of nitrocellulose to kraft pulp is high, the mechanical strength decreases, so it is necessary to add a large amount of synthetic resin.
Conversely, when the ratio of nitrocellulose to kraft pulp is low, unburned residue occurs when used with a gun, so it is necessary to reduce the amount of synthetic resin. In addition, ethyl centralite or diphenylamine can be blended as a stabilizer for suppressing spontaneous decomposition of nitrocellulose. These mixing ratios are appropriately selected depending on the required performance of the used gun.

Or, it was found to have 3 to 5 times the separating power as compared with 2.
The burnout container used is loaded with propellant to make it the same weight as the artillery propellant charge, and the module weighs 2.4 kg per piece. The purpose of this burnout container is to connect and use six modules. In this case, the six modules are placed in a state of being connected in the vertical direction, and when one module at the upper end is lifted, The weight of 12.0 kg of the remaining five modules works at the joint just below the module. Usually, the propellant charge is often handled in this way, but in Comparative Examples 1 and 2, it can be seen that it is separated even by this handling. On the other hand, in Examples 1, 2, and 3, this treatment is at a level that does not separate.
