Abstract
The present invention relates to a kind of charge constitution for improving beehive-shaped charge Penetration Speed, including initiator, explosive column and cavity liner, explosive column one end is connected with initiator, and the other end is equipped with cavity liner, and initiator, explosive column and cavity liner three's axis overlap；It is additionally provided with hole ball on explosive column, is air inside the hole, the centre of sphere is located on the central axis of explosive column, and close to cavity liner top.The present invention had both had big penetration aperture, can also improve and wear depth, and on the basis of existing big penetration aperture beehive-shaped charge, under conditions of penetration aperture does not reduce, Penetration Speed can be improved 15% or more, and powder charge capacity usage ratio is high, had wide applicability.
Description
Technical field
The present invention relates to a kind of novel loaded constitution of power-assembling structures that cumulative Penetration Speed can be improved.
Background technique
Using beehive-shaped charge technology, penetration is carried out to target or structures or is run through, is had in national defence and civilian industry
It is widely applied, often under limited charge space size constraint, should guarantee enough penetration apertures, it is also desirable to have
Have it is enough wear depth, to the design of beehive-shaped charge, more stringent requirements are proposed.Traditional beehive-shaped charge form as shown in Figure 1, is
Raising penetration aperture, often uses the cavity liner or segment-shaped cavity liner of big cone angle, but is formed by effluxvelocity often
It is lower than small-angle, it wears deep smaller.
Summary of the invention
Technical problem solved by the present invention is in order to solve this problem, this programme proposes a kind of new beehive-shaped charge knot
Structure can effectively improve Penetration Speed on the basis of big penetration aperture beehive-shaped charge form.
The technical scheme is that a kind of charge constitution for improving beehive-shaped charge Penetration Speed, including initiator, explosive
Column and cavity liner, explosive column one end are connected with initiator, and the other end is equipped with cavity liner, and initiator, explosive column and cavity liner three
Axis overlaps；It is air inside the hole it is characterized in that, being additionally provided with hole ball on explosive column, the centre of sphere is located at explosive
On the central axis of column, and close to cavity liner top.
A further technical solution of the present invention is: the hole radius of a ball is R, it is highly H that explosive column diameter, which is φ, medicine
Type cover maximum gauge is C, and axial height B, hole ball is close to the distance between the one end on cavity liner top and cavity liner top
For A；As H=(1.2~1.5) φ, R=(1/9~1/7) φ, R=(0.4~0.6) A.
A further technical solution of the present invention is: the hole outer surface of ball is made of the meltable material of plasticity.
Invention effect
The technical effects of the invention are that: the present invention increases a hole inside traditional beehive-shaped charge, works as detonation
Gas, which forms speed, when wave reaches hole top, in hole shifts to an earlier date hole lower part explosive greater than the strong shock wave of detonation wave velocity
Detonation improves detonation wave profile, is conducive to cavity liner overturning, while when detonation product is assembled into hole forms energy-gathering jetting,
It can also reinforce the impetus to cavity liner, to improve Penetration Speed.The novel energy-focusing charge constitution of this programme, both had
Big penetration aperture, can also improve and wear depth, on the basis of existing big penetration aperture beehive-shaped charge, not reduce in penetration aperture
Under the conditions of, Penetration Speed can be improved 15% or more, and powder charge capacity usage ratio is high, have wide applicability.
Detailed description of the invention
Fig. 1 is traditional big penetration aperture beehive-shaped charge form.
Fig. 2 is the beehive-shaped charge form for improving Penetration Speed.
Fig. 3 is the beehive-shaped charge technology mode for improving Penetration Speed.
In figure: 1. initiators, 2. explosives, 3. holes, 4. cavity liners, 5. top gun propellant separated loading charges, 6. spherical dies, 7. lower parts
Powder charge.
Specific embodiment
- Fig. 3 referring to fig. 2, a kind of loaded constitution of power-assembling that Penetration Speed can be improved, including initiator 1, explosive 2, hole
3 with cavity liner 4.Hole 3 is located at the axial centerline of powder charge, is spherical, radius R, and the overall dimensions of beehive-shaped charge are φ
× H, 4 finish dimensional of cavity liner are C, and high B, 3 lower part of hole is A away from 4 top of cavity liner.In H=(1.2~1.5) φ, hole 3
Size and positional relationship meet: when R=(1/9~1/7) φ, R=(0.4~0.6) A, Penetration Speed can be effectively improved, simultaneously
Penetration aperture is not reduced yet.
Loading method is described as follows by step:
A) when using press-loading process powder charge, including following sub-step:
Sub-step one: will manufacture the spherical die 6 of hole ball 3, make the outer of top gun propellant separated loading charge 5 and lower part gun propellant separated loading charge 7
Shell mold tool.(upper and lower two parts powder charge is boundary with the center in hole 3)
Sub-step two: using two parts outer casing mold combination spherical die 6, suppresses two parts powder charge up and down.
Sub-step three: powder charge sloughs all molds after suppressing, and obtains naked powder column.
Sub-step four: in the weapon explosive assembly casing of the application charge structure, the naked powder column of upper and lower two parts is assemblied into
Whole, the powder charge for inserting weapon is intracavitary.
B) when using dress technique powder charge is cast, including following sub-step:
Sub-step one: the spherical die 6 of hole ball 3 is manufactured.
Sub-step two: in the weapon explosive assembly casing of the application charge structure, lower part of first being cast using spherical die 6
Powder charge 7.(upper and lower two parts powder charge is boundary with the center in hole 3)
Sub-step three: after 7 basic forming of lower part gun propellant separated loading charge, spherical die 6 is removed, is packed into hole ball 3.
Sub-step four: in the weapon explosive assembly casing of the application charge structure, then top gun propellant separated loading charge 5 of casting.
It is air inside hole 3, outer surface uses the meltable material of plasticity with some strength.Refering to Fig. 3, by whole dress
Medicine is divided into top gun propellant separated loading charge 5 and 7 two parts of lower part gun propellant separated loading charge by the center in hole 3.It, can be with for the explosive of press-loading process
The cavity portion that spherical die 6 is used to form top gun propellant separated loading charge 5 Yu lower part gun propellant separated loading charge 7, Zhi Houqu are made according to the size in hole 3
Lower mold 6, is assemblied into whole powder charge.For the explosive of casting dress technique, it can guarantee charge process in such a way that substep is cast
Quality first cast lower part gun propellant separated loading charge 7 using spherical die 6, remove spherical die 6 and be packed into hole ball 3 and then top of casting
Gun propellant separated loading charge 5.
