Description

Shell device filled with ten-ton-grade solid-liquid phase mixed fuel and having differential pressure stirring function

Technical Field

The invention belongs to the technical field of fuel filling shells, relates to a shell filled with ten-ton-grade solid-liquid phase mixed fuel, and particularly relates to a shell device filled with ten-ton-grade solid-liquid phase mixed fuel and having a differential pressure stirring function.

Background

The high-energy liquid-phase fuel is thrown into the air through the explosive explosion throwing driving action, the high-energy liquid-phase fuel is atomized and mixed with the air to form a large-range active cloud cluster, and the active cloud cluster generates body detonation through secondary detonation of the explosive to release strong shock waves, so that the high-energy liquid-phase fuel weapon is one of the most powerful weapons.

The improvement of the explosive power of the body detonation warhead mainly depends on the improvement of the energy of the internally filled fuel, and the improvement is reported in the literature "high power FAE liquid fuel optimization selection" (fire and explosive bulletin 2016, page 14 of 3 rd year): the metal powder is added into the liquid fuel, the liquid fuel and the metal powder are mixed to form the solid-liquid mixed fuel, and the energy of the fuel in the body detonation warhead can be greatly improved due to the high heat value of the metal powder.

With competitive development of weapon technologies at home and abroad, the power demand on the weapon is further improved, and the most direct method for improving the power of the warhead is to increase the size of the warhead. Along with the gradual improvement of the bearing capacity of the weapon platform, the carrying size is gradually increased, the large size of processing equipment is improved, the size of a warhead can be designed to be larger and larger, and at present, the weight of fuel loaded in the body detonation warhead can reach ten tons at most.

Because the solid-liquid phase mixed fuel can not be mutually dissolved and the densities of all components are different, the fuel with higher density in the solid-liquid phase mixed fuel can be settled to the lower part and the fuel with lower density can be lifted to the upper part under the action of gravity. The solid-liquid phase mixed fuel which is uniformly mixed can only be maintained for about one week, and the layering of the solid-liquid phase fuel and the liquid-phase fuel is very obvious after more than one week through practical observation. When the body detonation warhead is actually applied, solid-phase fuel and liquid-phase fuel are inevitably layered after the charging is finished and the actual use is carried out for a plurality of years.

The proportion of each component given by the solid-liquid phase mixed fuel in the process of developing the formula is the proportion of the maximum power. Once the solid-liquid phase mixed fuel is layered, the fuel at each part cannot participate in the explosion reaction in the maximum power proportion during subsequent scattering and secondary detonation. The royal sea et al report in the literature "experimental study of cloud detonation characteristics of gas-liquid-solid three-phase system" (high pressure physical report, 12 months 2014, volume 28, page 6, 671): when the proportions of the components of the solid-liquid mixture are different, the detonation pressure, the detonation velocity and the critical detonation energy of the body detonation are different greatly, and the power of the body detonation warhead is greatly reduced due to the change of the proportions of the components of the solid-liquid mixture.

After the solid-liquid phase mixed fuel is layered, the mass center of the body detonation warhead is changed along with the solid-liquid phase mixed fuel. The lie et al report in the document "trend toward centroid measurement and calibration technology" (measurement technology, 2016, vol 36, page 2, 1): in the field of defense, the position of a mass center is related to the flight attitude, the flight speed and the flight direction of a warhead, and finally the trajectory of the warhead is influenced, the flight trajectory of the warhead depends on the mass center, a guidance system and other factors, when the mass center of the warhead deviates from a flight plane, an additional moment is given to the warhead to change the motion trajectory of the warhead, the radial mass center deviation of the warhead can cause the warhead to generate a yawing moment, the axial mass center deviation can cause the pitching moment of the warhead, and the severe mass center deviation can cause the warhead to lose balance or deviate from the trajectory, so that the warhead cannot hit a target area, and therefore, the mass center deviation can cause the hit precision of the warhead on a target to be reduced.

For the small-volume and light-weight body detonation warhead, the internal layered solid-liquid phase fuel can be remixed by rolling back and forth before use, and the weight of the shell filled with ten tons of solid-liquid phase mixed fuel is too large to remix the internal fuel in a rolling mode.

the baffle 5 is a fifth rectangular plate, the front and the back of the baffle 5 are rectangles, the upper end surface of the baffle 5 is a fifth upper narrow and long plane, the lower end surface of the baffle 5 is a fifth lower narrow and long plane, the left end surface of the baffle 5 is a fifth left narrow and long plane, the right end surface of the baffle 5 is a fifth right narrow and long plane, and the total number of the baffles 5 is twelve;

the solid-liquid phase mixed fuel 6 is a ten-ton grade solid-liquid phase mixed material, solid and liquid are layered under the action of gravity, and the solid and liquid are uniformly mixed by the method;

the using method and the working principle of the invention are as follows:

step 1: assembling a shell 1, an upper end cover 2, a lower end cover 3, a scattering device 4 and a baffle 5 into a warhead shell, wherein the baffle 5 divides the internal space of the warhead shell into twelve intervals;

and 2, step: filling solid-liquid phase mixed fuel 6 into a closed space formed by the shell 1, the upper end cover 2, the lower end cover 3 and the scattering device 4;

and step 3: connecting the lower end of the eighth round tube of the guide tube 8 with one of the second peripheral round holes of the upper end cover 2;

and 6: after the inner cavity of the mixing chamber 7 is filled with the solid-liquid phase mixed fuel 6, stopping vacuumizing the seventh upper-end circular through hole of the mixing chamber 7, enabling the solid-liquid phase mixed fuel 6 in the mixing chamber 7 to flow downwards and enter the inner cavity of the warhead shell again, and connecting the lower end of an eighth circular pipe of the guide pipe 8 with a second peripheral circular hole of the upper end cover 2 next to the pointer;

The working principle of the invention is as follows:

the solid-phase fuel and the liquid-phase fuel in the solid-liquid phase mixed fuel 6 are layered under the action of gravity, and the solid-phase fuel and the liquid-phase fuel in the solid-liquid phase mixed fuel 6 are subjected to relative movement, convection occurs, and the solid-phase fuel and the liquid-phase fuel are re-mixed, so that the aim of uniform mixing can be fulfilled. The difficulty is that all solid-phase fuel and liquid-phase fuel in the solid-liquid phase mixed fuel 6 are required to be mixed, and the mixing needs a certain speed, and the mixing speed is enough to have enough mutual impact, so that the aim of uniform mixing can be achieved. The inner cavity of the warhead is divided into twelve sections, the upper end of one section is vacuumized, due to the pressure difference existing in the inner cavity of the warhead, solid-liquid phase mixed fuel 6 in the vacuumized section naturally flows upwards to enter a mixing chamber 7, the liquid level of solid-liquid phase mixed fuel 6 in other sections moves downwards, and solid-phase materials in the solid-liquid phase mixed fuel 6 are deposited at the lower end under the action of gravity, so that the solid-liquid phase mixed fuel 6 in other sections flows to the vacuumized section through a narrow gap between a baffle 5 and a lower end cover 3, the solid-phase materials deposited in the solid-liquid phase mixed fuel 6 at the lower end are impacted by the liquid flow in the solid-liquid phase mixed fuel 6, and the solid-liquid phase fuel and the liquid phase fuel in the solid-liquid phase mixed fuel 6 are relatively moved, and mixed. Because the solid-liquid phase mixed fuel 6 in the vacuumized interval in the inner cavity of the warhead is completely sucked into the mixing chamber 7, the liquid phase fuel and the solid phase fuel in the interval are all mixed, and through the other intervals which are vacuumized next to each other, finally, some fuel is mixed again, so that no dead angle can be ensured. The solid-liquid phase mixed fuel 6 which is uniformly re-mixed still can be layered under the action of gravity, but the layering has a time process, and experiments show that the liquid phase fuel has a certain year, is mixed with the solid phase fuel, the layering amount is limited within three days after the liquid phase fuel and the solid phase fuel are uniformly re-mixed, the concentration ratio of each position is still within an allowable range, and the mass center offset of the body detonation warhead is within an acceptable error range, so the solid-liquid phase mixed fuel has practical use significance.

When the gap between the fifth lower end long and narrow plane of the baffle 5 and the upper end face of the lower end cover 3 is too large, the resistance to the flow of the solid-liquid phase fuel mixture 6 through the gap is reduced, and when the total flow rate of the solid-liquid phase fuel mixture 6 is the same, the larger the gap is, the smaller the flow resistance of the solid-liquid phase fuel mixture 6 is, the lower the flow speed of the solid-liquid phase fuel mixture 6 is, since the solid-liquid phase fuel in the solid-liquid phase fuel mixture 6 is deposited at the lower end, that is, the gap part mainly between the fifth lower end long and narrow plane of the baffle 5 and the upper end face of the lower end cover 3, the mixing operation will fail if the flow speed of the solid-liquid phase fuel mixture 6 is sufficient and the solid-liquid phase fuel in the solid-liquid phase fuel mixture 6 cannot be impacted and moved, and the gap between the fifth lower end long and narrow plane of the baffle 5 and the upper end face of the lower end cover 3 is too small, the resistance of the solid-liquid phase mixed fuel 6 flowing through the gap is too large, the flow rate in unit time is too small due to too small gaps, the working time is increased, and on the other hand, if the gap is too small, the solid phase mixed fuel is easily and completely blocked by the solid phase fuel in the solid-liquid phase mixed fuel 6, and the invention is invalid. Through a large amount of experiments, when the clearance between the narrow long plane of fifth lower extreme of baffle 5 and the 3 up end of lower extreme lid was 6 ~ 9mm, above-mentioned problem all can be avoided, and above-mentioned function all can be realized, satisfies the operation requirement.

In this embodiment, the gap between the fifth lower narrow long plane of the baffle 5 and the upper end surface of the lower end cover 3 is 6 mm;

the distance between the front and the back of the baffle 5 is the thickness of the baffle 5, when the thickness of the baffle 5 is too small, the strength of the baffle 5 is insufficient, because the solid-liquid phase mixed fuel 6 in the invention is mixed by pressure difference, the inner layer and the outer layer of the baffle 5 are subjected to different pressures, if the strength is insufficient, the baffle can be broken, the invention fails, when the thickness of the baffle 5 is too large, the baffle can play a role in hindering the subsequent fuel scattering of a warhead to form a cloud cluster, and the power of the warhead is reduced. Through a large amount of experiments, the thickness of the baffle 5 is 5-8 mm, the problems can be avoided, the functions can be realized, and the use requirement is met.

In this embodiment, the thickness of the baffle 5 is 5 mm;

when the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 is too small, the volume of the mixing chamber 7 is too small, the solid-liquid phase mixed fuel 6 is sucked into the inner cavity of the mixing chamber 7 and then released for mixing, if the volume of the mixing chamber 7 is too small, the mixing amount is too small each time, the uniform mixing effect cannot be achieved, and when the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 is too large, the volume of the solid-liquid phase mixed fuel 6 sucked into the inner cavity of the mixing chamber 7 is too large each time for sucking is too long. Through a large number of experiments, it was found that the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixture fuel 6 was 1: 5-6, the problems can be avoided, the functions can be realized, and the use requirements are met.

In this embodiment, the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 is 1: 5;

in the invention, the solid-liquid phase mixed fuel 6 is mixed mainly by sucking the solid-liquid phase mixed fuel 6 into the inner cavity of the shell of the warhead part after being lifted to the inner cavity of the mixing chamber 7, if the gravitational potential energy increment is too small, the speed of putting the solid-liquid phase mixed fuel 6 into the inner cavity of the shell of the warhead part is too small, the mixing effect is reduced, and the effect of full mixing cannot be achieved. When the distance between the lower end face of the mixing chamber 7 and the upper end face of the upper end cover 2 is too large, the increase of gravitational potential energy is too large after the solid-liquid phase mixed fuel 6 is lifted to the inner cavity of the mixing chamber 7, the speed of the solid-liquid phase mixed fuel 6 being put back to the inner cavity of the shell of the warhead is too large, the solid-liquid phase mixed fuel 6 easily overflows from other second peripheral circular holes of the warhead 2, and the total fuel amount filled in the warhead is reduced. A large number of experiments find that when the distance between the lower end face of the mixing chamber 7 and the upper end face of the upper end cover 2 is 11-14 mm, the problems can be avoided, the functions can be realized, and the use requirements are met.

In the embodiment, the distance from the lower end surface of the mixing chamber 7 to the upper end surface of the upper end cover 2 is 11 mm;

processing a ten-ton warhead shell filled with the original scheme, filling the solid-liquid mixed fuel 6, standing for one month, measuring the mass center of the mixture, and measuring the concentration distribution of each part of the mixture. The experiment result shows that the mass center offset exceeds 23 percent of the total length of the warhead, and the maximum deviation of the concentration distribution of different parts exceeds 61 percent.

Ten warhead shells filled with ten tons of powder are processed, solid-liquid phase mixed fuel 6 is filled, the warhead shells are kept still for one month, the mass center of the warhead shells is measured, and the concentration distribution of each part of the warhead shells is measured, but the solid-liquid phase mixed fuel 6 is remixed by the invention three days before the measurement. The experimental result shows that the mass center offset is lower than 1% of the total length of the warhead, and the maximum deviation of concentration distribution of different parts exceeds 5%.

the internal space of the warhead shell is divided into twelve intervals, fuel in each interval is sucked into the mixing chamber by using pressure difference, and layered solid-phase fuel and liquid-phase fuel are mixed again until the mixture is uniform, and the concentration ratio of each component reaches the design value. According to the invention, the fuel at any position in the shell is uniformly stirred without dead angles, the stirring work is completed within three days before the explosion of the warhead, the separation of each component is limited within three days after the stirring, the concentration ratio of each position is still within an allowable range, the fuel can participate in detonation at a better concentration ratio when the warhead is detonated, and the power of the warhead is ensured. The mass center offset of the body detonation warhead is within an acceptable error range, so that the influence of the mass center offset of the warhead on the trajectory is avoided, and the target hitting precision is guaranteed.

the shell filled with ten-ton-grade solid-liquid phase mixed fuel and having a differential pressure stirring function comprises the following steps of:

step 6: after the inner cavity of the mixing chamber 7 is filled with the solid-liquid phase mixed fuel 6, stopping vacuumizing the seventh upper-end circular through hole of the mixing chamber 7, enabling the solid-liquid phase mixed fuel 6 in the mixing chamber 7 to flow downwards and enter the inner cavity of the warhead shell again, and connecting the lower end of an eighth circular pipe of the guide pipe 8 with a second peripheral circular hole of the upper end cover 2 next to the pointer;

The working principle of the invention is as follows:

When the gap between the fifth lower end long narrow plane of the baffle 5 and the upper end face of the lower end cap 3 is too large, the resistance to the flow of the solid-liquid phase mixed fuel 6 through the gap is reduced, and when the total flow rate of the solid-liquid phase mixed fuel 6 is the same, the larger the gap is, the smaller the flow resistance of the solid-liquid phase mixed fuel 6 is, and the lower the flow speed of the solid-liquid phase mixed fuel 6 is, since the solid-liquid phase fuel in the solid-liquid phase mixed fuel 6 is deposited on the lower end, that is, the gap portion mainly between the fifth lower end long narrow plane of the baffle 5 and the upper end face of the lower end cap 3, the mixing operation will fail if the flow speed of the solid-liquid phase mixed fuel 6 is too low to impact and move the solid-liquid phase fuel in the solid-liquid phase mixed fuel 6, and the gap between the fifth lower end long plane of the baffle 5 and the upper end face of the lower end cap 3 is too small, the resistance of the solid-liquid phase mixed fuel 6 flowing through the gap is too large, the gap is too small, the flow rate in unit time is too small, the working time is increased, and on the other hand, if the gap is too small, the solid phase mixed fuel is easily and completely blocked by the solid phase fuel in the solid-liquid phase mixed fuel 6, and the invention fails. Through a large amount of experiments, when the clearance between the narrow long plane of fifth lower extreme of baffle 5 and the 3 up end of lower extreme covers was 6 ~ 9mm, above-mentioned problem all can be avoided, and above-mentioned function all can be realized, satisfies the operation requirement.

In this embodiment, the gap between the fifth lower narrow long plane of the baffle 5 and the upper end surface of the lower end cover 3 is 9 mm;

the distance between the front and the back of the baffle 5 is the thickness of the baffle 5, when the thickness of the baffle 5 is too small, the strength of the baffle 5 is insufficient, because the solid-liquid phase mixed fuel 6 in the invention is mixed by pressure difference, the inner layer and the outer layer of the baffle 5 are subjected to different pressures, if the strength is insufficient, the baffle can be broken, the invention fails, when the thickness of the baffle 5 is too large, the baffle can play a role in hindering the subsequent fuel scattering of a warhead to form a cloud cluster, and the power of the warhead is reduced. Through a large amount of experiments, when baffle 5's thickness was 5 ~ 8mm, above-mentioned problem all can be avoided, and above-mentioned function all can be realized, satisfies the operation requirement.

In this embodiment, the thickness of the baffle 5 is 8 mm;

when the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 is too small, the volume of the mixing chamber 7 is too small, the solid-liquid phase mixed fuel 6 is sucked into the inner cavity of the mixing chamber 7 and then released for mixing, if the volume of the mixing chamber 7 is too small, the mixing amount is too small each time, the effect of uniform mixing cannot be achieved, and if the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 is too large, the volume of the solid-liquid phase mixed fuel 6 sucked into the inner cavity of the mixing chamber 7 is too large, the time of each suction is too long, and the invention is not practical because the invention starts within 3 days before the experiment and needs to complete the mixing work quickly, and the time is too long. Through a large number of experiments, it was found that the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 was 1: 5-6, the problems can be avoided, the functions can be realized, and the use requirements are met.

In this embodiment, the ratio of the volume of the mixing chamber 7 to the total volume of the solid-liquid phase mixed fuel 6 is 1: 6;

in the invention, the solid-liquid phase mixed fuel 6 is mainly sucked into the inner cavity of the mixing chamber 7 and then is put back into the inner cavity of the shell of the warhead part, if the gravitational potential energy increment is too small, the speed of putting the solid-liquid phase mixed fuel 6 back into the inner cavity of the shell of the warhead part is too small, the mixing effect is reduced, and the effect of fully mixing cannot be achieved. When the distance from the lower end surface of the mixing chamber 7 to the upper end surface of the upper end cover 2 is too large, the solid-liquid phase mixed fuel 6 is lifted to the inner cavity of the mixing chamber 7, the increase of gravitational potential energy is too large, the speed of the solid-liquid phase mixed fuel 6 being put back to the inner cavity of the shell of the warhead is too large, the solid-liquid phase mixed fuel 6 easily overflows from the second peripheral circular holes of other warheads 2, and the total fuel amount filled in the warhead is reduced. A large number of experiments find that when the distance between the lower end face of the mixing chamber 7 and the upper end face of the upper end cover 2 is 11-14 mm, the problems can be avoided, the functions can be realized, and the use requirements are met.

In this embodiment, the distance from the lower end surface of the mixing chamber 7 to the upper end surface of the upper end cover 2 is 14 mm;

processing an original scheme of ten-ton-level warhead shell, filling solid-liquid phase mixed fuel 6, standing for one month, measuring the mass center of the warhead shell, and measuring the concentration distribution of each part of the warhead shell. The experimental result shows that the mass center offset exceeds 23% of the total length of the warhead, and the maximum deviation of concentration distribution of different parts exceeds 61%.

the internal space of the warhead shell is divided into twelve intervals, fuel in each interval is sucked into the mixing chamber by using pressure difference, layered solid-phase fuel and layered liquid-phase fuel are mixed again until the mixture is uniform, and the concentration ratio of each component reaches the design value. The invention uniformly stirs the fuel at any position in the shell without dead angle, the stirring work is completed within three days before the explosion of the warhead, the separation of each component is limited within three days after the stirring, the concentration ratio of each position is still within the allowable range, the fuel can participate in the detonation with the better concentration ratio when the warhead is detonated, and the power of the warhead can be ensured. The mass center offset of the body detonation warhead is within an acceptable error range, so that the influence of the mass center offset of the warhead on the trajectory is avoided, and the target hitting precision is guaranteed.
