The working principle of the automatic adjusting device for the internal pressure of the movable end cover is as follows:
the shell of the body detonation warhead is a thin-wall shell, the internal pressure bearing capacity is lower, and the volume expansion coefficient of the high-energy fuel in the body detonation warhead is larger than that of the shell, so that after the temperature is increased, the high-energy fuel expands to generate internal stress which is enough to break the shell.
In order to solve the problem of excessive internal stress after temperature rise, the movable end cover type internal pressure automatic regulating device of the embodiment adopts the movable end cover 2 which can move up and down in the first annular groove of the body detonation warhead shell 1, during upward movement, the space of high-energy fuel becomes smaller, during downward movement, the space of the high-energy fuel becomes larger, that is, the volume of the body detonation warhead shell 1 of the embodiment can be freely regulated, through regulating the volume, the volume is consistent with the volume of the high-energy fuel after thermal expansion and cold contraction, the generation of the internal stress is avoided, and the body detonation warhead shell is protected.
However, if air exists in the shell of the body detonation warhead, the air is wrapped by high-energy fuel, and when the explosive is thrown, the air is compressed to form hot spots, so that fire leaps are caused.
Because the inner cavity of the shell of the body detonation warhead is not provided with air, the fire leaping factor is avoided.
After the explosive is exploded and thrown, the temperature of the explosion product of the explosive is air but no fuel, the three burning factors are not satisfied, the high-energy fuel moves outwards to form a cloud cluster, the fuel is air but no temperature, and the three burning factors are not satisfied, so that the occurrence of fire leaping can be avoided.
In this embodiment, the body detonation warhead casing 1 is a casing of a body detonation warhead, and is used for loading and throwing explosives and fuel.
The movable end cap 2 is an innovation of the automatic adjusting device for the internal pressure of the movable end cap in the embodiment, the volume is adjusted by moving the movable cover plate 2 up and down, and air is not introduced into the shell 1 of the body detonation warhead.
The two-section type scattering device 3 contains explosives which are a power source for scattering fuel to form a cloud cluster, the two-section type scattering device 3 is composed of an upper section and a lower section, a third soft rope is a detonating cord and can propagate explosion, and the upper section and the lower section of the two-section type scattering device 3 are connected through the third soft rope.
The fuel 4 is a throwing explosive and fuel (also called high-energy fuel) filled inside the body detonation warhead.
The movable end cover 2 is assembled with the two-section type throwing device 3 and the body detonation warhead shell 1, the upper end face of a second circular plate of the movable end cover 2 is 5mm away from the upper end face of a first annular groove of the body detonation warhead shell 1, and the lower end face of the second circular plate of the movable end cover 2 is 14mm away from the lower end face of the first annular groove of the body detonation warhead shell 1. The installation is that considering thermal expansion and cold contraction simultaneously, the second plectane of movable end cover 2 can upwards remove also can downwards remove, considers actual conditions, and the temperature is reduced to minimum, and high energy fuel volume contracts to minimum, and movable end cover 2 upwards removes 5mm, and the volume of body detonation warhead casing 1 just is unanimous with fuel 4 volume, therefore design so. Similarly, the temperature is raised to the maximum, the volume of the high-energy fuel is increased to the maximum, the movable end cover 2 moves downwards by 14mm, and the volume of the body detonation warhead shell 1 is exactly consistent with the volume of the fuel, so the design is carried out. If the margin is too large, the stiffness is too large, and if the margin is insufficient, the adjusting capability is insufficient, and the internal stress is generated.
The inventor finds in tests that after the two-section type scattering device 3 explodes, the fuel 4 is scattered to form a cloud cluster, the shell 1 of the body detonation warhead part is impacted by explosive explosion in the two-section type scattering device 3 and moves upwards, the movable end cover 2 is impacted by explosive explosion in the two-section type scattering device 3 and moves downwards, and when the cloud cluster is flat, the subsequent power is the largest, and if the cloud cluster is irregular in shape, the explosion power is also influenced.
When the ratio of the distance between the lower end face of the first annular groove and the lower end face of the first lower annular boss of the body detonation warhead shell 1 to the thickness of the second circular plate of the movable end cover 2 is too small, the distance between the lower end face of the first annular groove and the lower end face of the first lower annular boss of the body detonation warhead shell 1 is too small, the movable end cover 2 is supported by the thickness of the part, namely, the supporting capacity for the movable end cover 2 is insufficient, the movable end cover 2 moves downwards after being impacted by explosive, and when the supported force of the movable end cover 2 is insufficient, the movable end cover 2 is firstly damaged, shells above and below a cloud cluster are damaged asymmetrically, a regular flat cylindrical cloud cluster cannot be formed, and the subsequent power is influenced.
When the ratio of the distance between the lower end surface of the first annular groove and the lower end surface of the first lower annular boss of the body detonation warhead shell 1 to the thickness of the second circular plate of the movable end cover 2 is too large, the distance between the lower end surface of the first annular groove and the lower end surface of the first lower annular boss of the body detonation warhead shell 1 is too large, which causes the stiffness to be too large and influences the fuel loading amount.
Through partial theoretical calculation, workers with relevant working experience are summoned to conduct collective consultation and discussion, the problems are resolved, and each module is subjected to experimental evaluation independently. The final experimental evaluation results show that the ratio of the distance between the lower end surface of the first annular groove and the lower end surface of the first lower end annular boss of the body detonation warhead shell 1 and the thickness of the second circular plate of the movable end cover 2 is 1: 0.8-0.85, the above problems can be avoided, the design advantages of the automatic movable end cap type internal pressure adjusting device of the present embodiment can be embodied, so that the functions can be well exerted, and the technical problems can be well solved by using the automatic movable end cap type internal pressure adjusting device of the present embodiment.

the ten movable end cover type internal pressure automatic adjusting devices of the embodiment are processed and used according to the using method of the device, and are respectively stored in the environment of +80 ℃ and-60 ℃, the shell 1 of the body detonation warhead is not damaged, the cloud cluster formed by the detonation two-section type throwing device 3 is flat and cylindrical, and fire leaping does not occur, so that the effect of the movable end cover type internal pressure automatic adjusting devices of the embodiment is proved.
According to the movable end cover type internal pressure automatic adjusting device, the movable end cover is adopted to adjust the volume of the inner cavity through up and down movement, so that the volume change caused by thermal expansion and cold contraction of fuel is compensated, the overlarge internal stress is avoided, and the safety of the shell of the body detonation warhead is ensured. Meanwhile, air does not exist in the inner cavity of the shell of the body detonation warhead, when explosive is thrown in an explosion mode, air is not compressed inside fuel, the three burning factors are not satisfied, the phenomenon of pre-ignition cannot occur, and the power of the body detonation warhead cannot be influenced.
Example 2:
example 2 differs from example 1 in that:
in this embodiment, the ratio of the distance between the lower end surface of the first annular groove and the lower end surface of the first lower annular boss of the body detonation warhead housing 1 and the thickness of the second circular plate of the movable end cap 2 is 1:0.85;
