The working principle of the automatic adjusting device for the internal pressure of the movable end cover of the embodiment is as follows:
the shell of the detonation warhead is a thin-wall shell, the internal pressure bearing capacity is low, and the volume expansion coefficient of the high-energy fuel in the detonation warhead is larger than that of the shell, so that when the temperature rises, 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 2 adopted in the automatic adjusting device for internal stress of the movable end cover type detonation warhead shell 1 can move up and down in the first annular groove of the movable end cover type detonation warhead shell 1, when moving upwards, the space of high-energy fuel is reduced, and when moving downwards, the space of high-energy fuel is increased, that is, the volume of the movable end cover type detonation warhead shell 1 can be freely adjusted, and the volume is adjusted to be consistent with the volume of the high-energy fuel after thermal expansion and cold contraction, so that the internal stress is avoided, and the body detonation warhead shell is protected.
However, if air exists in the body detonation warhead shell, high-energy fuel is wrapped around the air, and when the explosive is thrown, the air is compressed to form hot spots, so that fire is leaped.
Because no air exists in the inner cavity of the shell of the body detonation warhead, the factor of fire bouncing is avoided.
After the explosive is blasted, the temperature of the detonation product of the explosive is air but no fuel, the three elements of combustion are not satisfied, the high-energy fuel moves outwards to form cloud clusters, the fuel is air but no temperature, and the three elements of combustion are not satisfied, so that the occurrence of fire bouncing can be avoided.
In this embodiment, the body detonation warhead housing 1 is a housing of a body detonation warhead for loading and throwing explosives and fuels.
The movable end cover 2 is an innovation of the automatic pressure regulating device of the movable end cover type in the embodiment, and the volume is regulated by the up-and-down movement of the movable end cover 2, and meanwhile, air is not introduced into the body detonation warhead shell 1.
The explosive is contained in the two-section type throwing device 3, and is a power source for throwing fuel to form cloud clusters, the two-section type throwing device 3 consists of an upper section and a lower section, a third soft rope is a detonating cord and can spread explosion, and the upper section and the lower section of the two-section type throwing device 3 are connected by the third soft rope.
The fuel 4 is the thrown explosive and fuel (also called high-energy fuel) filled in the 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 surface of the second circular plate of the movable end cover 2 is 5mm away from the upper end surface of the first annular groove of the body detonation warhead shell 1, and the lower end surface of the second circular plate of the movable end cover 2 is 14mm away from the lower end surface of the first annular groove of the body detonation warhead shell 1. The installation is that the second circular plate of the movable end cover 2 can move upwards or downwards in consideration of thermal expansion and contraction, the temperature is reduced to the minimum in consideration of actual conditions, the volume of high-energy fuel is reduced to the minimum, the movable end cover 2 moves upwards by 5mm, and the volume of the body detonation warhead shell 1 is exactly consistent with the volume of the fuel 4, so the design is carried out. Similarly, the temperature rise is highest, 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 dead weight is too large, and if the margin is insufficient, the adjustment capacity is insufficient, and internal stress is generated.
In experiments, the inventor finds that after the two-section type throwing device 3 explodes, the fuel 4 is thrown to form a cloud cluster, the body detonation warhead shell 1 is subjected to the impact force of the explosion of the explosive in the two-section type throwing device 3, the movable end cover 2 moves upwards, the movable end cover 2 also is subjected to the impact force of the explosion of the explosive in the two-section type throwing device 3, the movable end cover moves downwards, and when the cloud cluster is flat, the subsequent power is the largest, for example, the cloud cluster is irregular in shape, and the explosion power is also influenced.
When the ratio of the distance between the lower end face of the first annular groove of the body detonation warhead shell 1 and the lower end face of the first lower annular boss 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 of the body detonation warhead shell 1 and the lower end face of the first lower annular boss is too small, the thickness of the part supports the movable end cover 2, namely the supporting capacity of the movable end cover 2 is insufficient, the movable end cover 2 moves downwards after being impacted by the explosive, and when the supporting force of the movable end cover 2 is insufficient, the movable end cover 2 is firstly damaged, the upper and lower shells of the cloud are damaged asymmetrically, and regular flat cylindrical cloud clusters cannot be formed, so that the subsequent power is affected.
When the ratio of the distance between the lower end face of the first annular groove of the body detonation warhead shell 1 and the lower end face of the first lower annular boss to the thickness of the second circular plate of the movable end cover 2 is too large, the distance between the lower end face of the first annular groove of the body detonation warhead shell 1 and the lower end face of the first lower annular boss is too large, so that the dead weight is too large, and the fuel loading capacity is affected.
Through partial theoretical calculation, workers who collect relevant working experience collectively negotiate discussions and decompose the problems, and each module independently carries out experimental evaluation. The final experimental evaluation result shows that the ratio of the distance between the lower end face of the first annular groove of the body detonation warhead shell 1 and the lower end face of the first lower annular boss to the thickness of the second circular plate of the movable end cover 2 is 1: when the pressure is 0.8-0.85, the problems can be avoided, the design advantages of the automatic pressure regulating device with the movable end cover can be embodied, the functions can be fully exerted, and the technical problems can be fully solved by using the automatic pressure regulating device with the movable end cover.

ten movable end cover type automatic internal pressure regulating devices of the embodiment are processed, and are used according to the using method of the device, and are stored in environments of +80 ℃ and-60 ℃, the detonation warhead shell 1 is not damaged, cloud clusters formed by detonating the two-section type throwing device 3 are flat cylinders, and fire bouncing does not occur, so that the movable end cover type automatic internal pressure regulating device of the embodiment is proved to be effective.
According to the movable end cover type automatic internal pressure adjusting device, the movable end cover is adopted to adjust the inner cavity volume through up-and-down movement, so that the change of the fuel expansion due to heat and contraction due to cold is made up, the excessive internal stress is avoided, and the safety of the body detonation warhead shell is ensured. Meanwhile, no air exists in the inner cavity of the shell of the body detonation warhead, when explosive is blasted, no air is compressed in the fuel, three factors of burnup are not satisfied, the phenomenon of pre-ignition cannot occur, and the power of the body detonation warhead cannot be influenced.

example 2 differs from example 1 in that:
in this embodiment, 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 housing 1 to the thickness of the second circular plate of the movable end cover 2 is 1:0.85;
