Known armor-piercing bullet has the shell case that has the inner step surface, and shell case has head, leader and afterbody.Lining and armor-piercing bullet core are installed in head, make by its protrusion like this and are fixed in the shell case.Playing core is fixed in the shell case along core and afterbody.Shell case is made ladder along outer surface, have the guiding surface of protrusion and the armour-piercing core between leader and afterbody, and the scope at the thickness of core shell case and the ratio of leader ball shell thickness is by 2 to 5 (patent RU No.2077021,1997).(patent RU No.2018780, No.2077021) armor piercing effect is to be realized by big bullet core diameter in known bullet design.Its scope is 0.66 to 0.85 (scope that plays core-bullet middle part section ratio is 0.43 to 0.74) of bullet calibre.Meanwhile definite, the principal element of decision bullet armor-penetrating ability is the unit energy that plays core, because shell case and lining reality are not participated in penetrating of obstacle.The shortcoming of known bullet design is that armour-piercing validity is not high, and it depends on the relation of bullet parameter.The method of known manufacturing armor-piercing bullet comprises that the bullet core that will have lining is press-fitted the head (patent US No.3069748,1962) that enters shell case and compression shell case.The method of known manufacturing armor-piercing bullet mainly is that the armor-piercing bullet core is protruded by shell case, method comprises that the bullet core that will have lining is press-fitted the head that enters shell case and compression shell case, the compression of shell case head here is to carry out simultaneously with shell case to the necking down of the side in the cutting coupling district that plays core, to obtain along shell case and to play the level and smooth transition (patent RU No.2082942,1997) of core outer surface.
In the method for two kinds of known manufacturing armor-piercing bullets (patent US No.3069748 and patent RU No.2082942), play core and protrude by shell case, the assembly surface that its bullet core afterbody is used is directly in shell case.The bullet core that will have lining then is press-fitted and enters shell case, carries out the compression of bullet head after this.When stating method in realization, the distortion of shell case when it causes shooting might be produced between bullet core end face and cartridge case base owing to the gap that exists mattress to form.The necessity in the gap between lining and shell case can cause the wall thickness of bullet correction back bush poor.Above-mentioned defective causes that the dispersion of ballistic performance and the aloft stability of bullet reduce, thereby finally reduces the penetration capacity of bullet.
Summary of the invention
The objective of the invention is to make the armor-piercing bullet that has the high-penetration ability, keep being similar to the size and the recoil impulse of same model bullet simultaneously again.From technological standpoint, the mode that reaches this purpose is:
-make armor-piercing bullet have the shell case of ladder, it comprises head, leader and afterbody, the armor-piercing bullet core is installed in wherein, makes by wherein protruding, and is connected with lining along the inner surface of shell case afterbody;
-to make the scope of bullet core-bullet middle part section ratio be 0.3 to 0.4;
-make the weight ratio that plays core and bullet be not less than 0.45;
-to make the scope at the thickness of afterbody shell case and the diameter ratio that plays core be 0.1 to 0.2;
-in making the method for armor-piercing bullet, this armor-piercing bullet has the armor-piercing bullet core that is protruded by shell case, and said method comprises that the bullet core that will have lining is press-fitted and enters shell case, and the head that compresses above-mentioned shell case:
When compressing the head of shell case, the method comprises that also compression is along the afterbody that plays core simultaneously.
Description of drawings
The present invention can understand better referring to accompanying drawing, wherein:
Fig. 1 illustrates the design drawing of the armor-piercing bullet that cuts part;
Fig. 2 illustrates the preceding position of armor-piercing bullet element in former and drift of compression section;
Fig. 3 illustrates the armor-piercing bullet figure behind the head that plays core compression shell case;
Fig. 4 illustrates the thickness that penetrated steel plate and the graph of a relation of distance;
Fig. 5 is illustrated in the volume in pulse hole temporary transient in the gel piece and the graph of a relation of distance.
The specific embodiment
The armor-piercing bullet of above-mentioned design (Fig. 1) has shell case 1, lining 2 and plays core 3.Shell case is a stairstepping, has head A, leader B and afterbody C.Afterbody at shell case has inner chamber, plays the assembling of core along its surface, with lining 2 and play core 3 be placed in the straight-cylindrical shell case 1 after (Fig. 2), they are placed in the former 4.When moving bullet by drift 5, in former, carry out the compression of shell case head, playing on the core until shell case and sealing.Drift has endoporus D, and it equals to play the diameter and the shell case double thickness sum of core.When drift further the further distortion of stress deformation pattern and shell case occurred by carrying out along playing core tail compression shell case when mobile in the head at shell case.So just cause shell case and play core not having the gap closely at head and afterbody and engaging, and with engage (Fig. 3) of lining.
