Description
Technical Field
The invention belongs to the technical field of mechanical fusion devices, relates to a mechanical fusion device for improving floating capacity, and particularly relates to a mechanical fusion device for improving floating capacity by increasing bubble volume.
Background
The high-energy fuel is filled in the bulk detonation warhead, and is thrown into the air under the explosive detonation throwing driving action, the high-energy fuel is mixed with the air to form a large-range active cloud cluster, and the active cloud cluster is subjected to secondary detonation by the explosive to generate bulk detonation, so that the high-energy fuel is one of the most powerful weapons. With the increasing power, the weight of the body detonation warhead has developed to the ten ton level.
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.
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. Once layered, the power of the body detonation warhead is greatly reduced, and the hit precision of the center of mass offset of the warhead on the target is reduced. In order to solve the problem of layering of solid-liquid phase mixed fuel under the action of gravity, gelling agent is added in the process of mixing the solid-liquid fuel and the liquid phase fuel, so that the solid-liquid fuel and the liquid phase fuel are gelled. The gelled state is viscous, and the gelled solid-liquid phase mixed fuel does not demix.
When the warhead is actually filled with the gelled solid-liquid phase mixed fuel, the solid-phase fuel, the liquid-phase fuel and the gel are uniformly mixed on a stirring and mixing device to form the gelled solid-liquid phase mixed fuel, and then the warhead shell is filled with the gelled solid-liquid phase mixed fuel. The weight of the warhead is 15-17 tons, the diameter of the warhead is 3.5-3.7 meters, the medicine loading opening is positioned in the center of the uppermost end of the warhead, the lower end of the scattering device is connected with an end cover of the warhead, the distance between the upper end of the scattering device and the end cover is 70-75 millimeters, and the diameter of the medicine loading opening is 0.6-0.8 meter.
In order to discharge the bubbles, a method is often adopted in which the body detonation warhead is heated, the viscosity of the gelled solid-liquid phase mixed fuel is reduced after the heating, the buoyancy force applied to the bubbles exceeds the viscous force of the fuel to the bubbles, the bubbles can gradually rise, and the bubbles can be discharged from the loading port in an ideal state. However, when the bubbles rise to the uppermost end of the body detonation part, the bubbles contact the upper end cover plate of the body detonation part, and the bubbles adhere to the lower surface of the upper end cover plate, and zhangyang et al reports "the influence of wall surface restraint on the dynamics of skirted gas bubbles" (mechanical report, 2017, 9 months, volume 49, page 5, 1050): after the bubbles in the fluid contact the inner wall of the housing, the movement of the bubbles is significantly resisted. The lower surface of upper end apron has great adsorption affinity to the bubble, leads to the bubble can't be automatic to the charge mouth removal, and ten tons of class warhead weight is great moreover, can't make inside bubble remove through vibrations or rolling, and the front end apron area is great moreover, and absorptive bubble is bulky great. Since the buoyancy of a bubble in fuel is proportional to the third power of its size and the viscous force of the bubble in fuel is proportional to the second power of its size, the larger the size of the bubble, the greater the ratio of buoyancy to viscous force it receives, the easier it moves, and guo et al report in the literature "kinetic behavior of a single bubble in viscous fluid" (proceedings of chemical engineering, 2009, 12 months, 23 vol. No. 6, page 917): the larger the size of the bubble, the stronger the floating capacity, and the easier it is to discharge from the loading port. The fuel has high viscosity, the bubbles are difficult to fuse with each other, the size of the bubbles is limited, and the bubbles are difficult to discharge from the fuel through floating. Once the air bubbles remain in the gelled solid-liquid phase fuel mixture, the air occupies the filling space of the fuel, the filling amount of the fuel is reduced, the total energy inside the warhead is reduced, and the power after the warhead explosion is influenced. The air contains oxygen, which is in contact with the fuel, and when the temperature is high, there is a risk of combustion, once the combustion occurs, explosion will occur, resulting in irreparable loss.

The working principle of the invention is as follows:
the body detonation warhead 1's upper end cover plate has adsorbed a large amount of bubbles on the terminal surface down, sweep the terminal surface under the upper end cover plate through the scraper blade 2 that gradually bursts at the seams, under the powerful drive effect of scraper blade 2 that gradually bursts at the seams, peel off the bubble from the terminal surface under the upper end cover plate by force, and with the bubble at the one side annular motion of scraper blade 2 that gradually bursts at the seams, after the bubble is gathered together by force, fuse together under the drive of scraper blade 2 that gradually bursts at the seams, the volume increases size increase after the bubble fuses, buoyancy increases, the floating capacity improves, can move to the center through buoyancy and discharge from the loading mouth. On the other hand, the normal direction of any point on the involute is tangent to the base circle. The force applied to the air bubbles under the driving action of the involute scraper 2 is tangential to the normal of the involute, namely the force applied direction of the air bubbles is tangential to the base circle and is directed to the center, and the air bubbles are applied with the force moving towards the center, namely the force moving towards the center can be used for driving the air bubbles to move towards the center. Can move to the charge opening to discharge upwards.
Regarding the second involute of the involute scraper 2, if the diameter of the base circle is too large, the curvature radius of the involute is too large, when the involute scraper 2 drives the bubble to move, the force applied to the bubble is tangent to the base circle, and the larger the base circle is, the farther the direction of the force applied to the bubble deviates from the central direction. The invention provides a force to the center of the bubble through the involute scraper 2, so that the bubble moves to the center and is discharged from a medicine charging port. If the force direction deviates from the center, the effect of the invention cannot be achieved, and even the efficiency of the invention is reduced. If the diameter of the base circle is too small, the curvature radius of the involute is too small, the second involute of the involute scraper plate 2 gradually opens from the base circle to the terminal, the rotation angle is too large, a large number of paths need to be wound, the path of the bubble moving from the edge to the center is increased, the longer the path of the bubble moving is, the greater the difficulty is, the more difficult the bubble is to be discharged, and the size of the second involute of the involute scraper plate 2 is too large, so that the cost is increased. Through a large number of experiments, the ratio of the base circle diameter of the second involute of the involute scraper blade 2 to the diameter of the body detonation warhead is 1: 21-25; in time, the problems can be avoided, the functions can be realized, and the use requirements are met.
Regarding the inclination angle of the middle upper portion of the second tapered narrow face of the involute flight 2, it is effective to merge the drive bubbles if the design is good. If the included angle between the middle upper part of the second inclined narrow surface of the involute scraper 2 and the second cylindrical axis of the involute scraper 2 is too small, that is, if the middle upper part of the second inclined narrow surface of the involute scraper 2 is close to vertical, the air bubbles only have horizontal force under the action of the involute scraper 2, but basically have no vertical force, the air bubbles can only move in the horizontal direction under the action of driving, and the process of the air bubbles being fused is too violent, and no buffer area exists. And after the upper portion has certain slope in the oblique narrow face of second that the scraper blade 2 gradually bursts at the seams, the bubble receives decurrent power, and the bubble can the downstream displacement distance, can fuse in the region of the scraper blade 2 downside that gradually bursts at the seams, and this gives the certain buffer zone of the fusion of bubble, and fusion that can be better is unlikely to produce the broken little bubble that forms too violently, is unfavorable for the discharge of bubble. And if the upper portion in the second inclined narrow face of involute scraper 2 and the second cylinder axis contained angle of involute scraper 2 were too big, namely if the upper portion in the second inclined narrow face of involute scraper 2 is close to when horizontal, the vertical direction's that the bubble produced under the effect of involute scraper 2 power was too big, and the bubble is too easy downstream, in case walk around from involute scraper 2 lower extreme, will unable through let the bubble along the scraper 2 that involute move to the center and discharge. A large number of experiments find that when the included angle between the middle upper part of the second oblique narrow surface of the involute scraper plate 2 and the axis of the second cylinder of the involute scraper plate 2 is 31-36 degrees, the problems can be avoided, the functions can be realized, and the use requirements are met.
The reason why the lowest end point of the second inclined narrow surface is designed to be bent is that a large number of bubbles can be gathered at the lower side of the involute scraper blade 2, and in order to enable the bubbles to move and be discharged along the involute center without crossing the lower end of the involute scraper blade 2 and staying in the warhead shell, the lowest end point of the second inclined narrow surface is designed to be bent, so that a connecting line of the lowest end point of the bent second inclined narrow surface and the highest end point of the second inclined narrow surface and the second inclined narrow surface form a region with a certain area, the region can contain the bubbles and is equivalent to a storage space for the bubbles, and therefore, the larger the space is, the more the bubbles can be stored, the more the bubbles are beneficial to collection and gathering of the bubbles, and finally all the bubbles can be contained from the regionThe medicine is discharged from the medicine filling port, and the area is not too large enough. Through a large number of experiments, the area enclosed by the connecting line of the lowest end point of the bent second inclined narrow surface and the uppermost end point of the second inclined narrow surface and the second inclined narrow surface is 5.1-8.9 mm 2 In time, the problems can be avoided, the functions can be realized, and the use requirements are met.
Regarding the ratio of the base circle diameter of the second involute of the involute scraper blade 2 to the diameter of the body detonation warhead, the included angle between the middle upper part of the second oblique narrow surface of the involute scraper blade 2 and the second cylindrical axis of the involute scraper blade 2, the area enclosed by the connecting line of the lowest endpoint of the second oblique narrow surface after bending and the highest endpoint of the second oblique narrow surface and the second oblique narrow surface, any one of the following 2 modes can be adopted:
implementation mode 1: the ratio of the base circle diameter of the second involute of the involute scraper blade 2 to the diameter of the body detonation warhead is 1: 21;
the included angle between the middle upper part of the second inclined narrow surface of the involute scraper plate 2 and the axis of a second cylinder of the involute scraper plate 2 is 31 degrees;
the area enclosed by the connecting line of the lowermost end point of the bent second inclined narrow surface and the uppermost end point of the second inclined narrow surface and the second inclined narrow surface is 5.1mm 2 。
Implementation mode 2: the ratio of the base circle diameter of the second involute of the involute scraper blade 2 to the diameter of the body detonation warhead is 1: 25;
the included angle between the middle upper part of the second inclined narrow surface of the involute scraper plate 2 and the axis of a second cylinder of the involute scraper plate 2 is 36 degrees;
the area enclosed by the connecting line of the lowermost end point of the bent second inclined narrow surface and the uppermost end point of the second inclined narrow surface and the second inclined narrow surface is 8.9mm 2 。
