Description
Technical field
The invention belongs to artillery technical fields, and in particular to kill quick-fried rocket projectile.
Background technology
Terrorist forces tend to be active in recent years, mostly using key city as target.City fight-terrorism warfare is in landform spy
Sign, enemy and we staggeredly etc. in terms of situation with traditional field operation there are significant difference, special requirement weaponry has low subsidiary lethal
Energy.The main man-portable rocket spininess equipped both at home and abroad at present grinds traditional operational environment (field operation) and target (armoured tank)
Hair, such as domestic DZJ00 formula 80mm individual soldier's multipurposes rocket projectile, rifle hairdo force open the door bullet, BKM2 type 80mm individual rockets assault fortified position bullet,
WPF80mm individual rockets are connected high explosive anti-tank cartridge etc., external as MK153 shoot from shoulder multipurposes are assaulted fortified position rocket projectile, M141 shoot from shoulders multipurpose fire
Arrow bullet, M3 karr Gustafs rocket projectile, C90 rocket projectiles etc. are mainly used for hitting traditional field operation target, and warhead does not examine
Consider it is low incidentally kill factor, exist to neighbouring friendly troop and innocent people cause killing risk.
To solve the problems, such as this, fight-terrorism warfare ability is improved, pickaback Individual Rocket Launching Tube is transmitting to the present invention with domestic active service
Platform proposes that a kind of individual soldier kills quick-fried rocket projectile, by low subsidiary warhead design technology and killing control of element technology, realizes low
The synergy of subsidiary performance and target area fragment action, not only effectively struck target, but also avoid injuring other people of target proximity
Member and object promote city fight-terrorism warfare equipment Development.
We has developed one kind and killing quick-fried rocket projectile in order to solve problem above.
Invention content
The purpose of the present invention is that solve the above-mentioned problems and provides one kind and killing quick-fried rocket projectile.
The present invention is achieved through the following technical solutions above-mentioned purpose：

Close other personnel and object.
Further, shell is ladder-like hollow rotary structure, is round between the larger diameter end and smaller diameter end of shell
Cambered surface transition structure, external screw thread and the internal thread of head-shield larger diameter end on shell larger diameter end excircle match, and shell is big
Diameter end is threadedly coupled with head-shield larger diameter end；The external screw thread phase of internal thread and fuse structure first end outer wall on head-shield inner wall
Matching, head-shield are threadedly coupled with fuse structure.
Shell and head-shield, fuse structure and head-shield are attached using screw connection structure so that each component is being kept
While installation is stablized, has quick detachable advantage.
Specifically, charge constitution is made of three sections of front segment structure, middle section structure and rear section structure, in front segment structure one end
Outer diameter of the aperture of heart blind hole slightly larger than the first end of fuse structure；The first end of fuse structure is placed in front segment structure one end
In heart blind hole；Front segment structure is placed in head-shield；Annular groove is opened in the side wall of middle section structure；Middle section structure and rear section structure are equal
It is placed in shell.
Such mounting structure ensure that rocket projectile when hitting target, fuse structure energy successful detonation charge constitution；
Each section of installation site of meeting charge constitution is relatively reasonable, and the center of gravity of entire rocket projectile has been transferred near middle.
Preferably, Hexal explosive is pressed in charge constitution.
Hexal explosive is with good bursting property.
Further, shell smaller diameter end outer round surface is uniformly arranged there are four empennage mounting groove, and four empennages fix peace
In four empennage mounting grooves, empennage is made of nylon66 fiber.
The setting of four empennages ensure that the stability of rocket projectile flight, and in rocket projectile explosion, what empennage generated
Fragment will not injure target and neighbouring other personnel and object substantially.
The beneficial effects of the present invention are：
The present invention's kills quick-fried rocket projectile：
1, when charge constitution explodes, controlled fragment component can fly out along the notch direction of charge constitution upper groove, and
It is not to all the winds dropping fire, by hazard boundary control in a certain range, precision strike target, and avoid injuring target attached
Close other personnel and object.
2, controlled fragment component includes hard polyurethane foam interlayer ring cylinder structure and multiple steel balls, and multiple steel balls pass through
Adhesive glue even adhesion is fixedly mounted in hard polyurethane foam interlayer ring cylinder structure；Using such mounting structure, make
Obtaining steel ball can preferably be fixed, and will not shake；And installation site of the steel ball in controlled fragment component further determines
The control of hazard boundary.
3, shell, head-shield made of nylon66 fiber, in rocket projectile explosion, the fragment of generation will not injure substantially target and
