Abstract
The utility model relates to a range extending shell, particularly a cannon rocket bottom range increasing shell which is 130 mm. The utility model comprises a warhead (1), rocket accelerating engine (2) and a bottom range device (3). The arc radium of the arc-shaped part of the bullet is matched with the arc radium of a fuze. The structure reduce the resistance and the frictional resistance of the head part of a bullet and enhance the ranges of shells. The utility model has the advantages of simple structure and reliable action. The utility model is suitable for the development of new shells and the improvement of various old shells.
Description
The utility model relates to a kind of extended range projectile, particularly a kind of 130 millimeters gun rocket base bleed range expansion bullets.
At present, old-fashioned artillery range is generally all nearer, can not satisfy the modern war requirement, then will cause very big waste as all discarding.
The purpose of this utility model is: old-fashioned shell is done some improvement, its maximum range is improved a lot.
The purpose of this utility model is achieved in that profile by improving bullet is to reduce head resistance, frictional resistance and projectile tail resistance, install the rocket boost engine additional to increase flying speed and the height of bullet on ascending branch of the trajectory, install bottom row device additional to reduce resistance at the bottom of the bullet.
Bullet curved portions radius and fuse arc radius match; Bullet portion relative length is 3d～4d.Shell cylinder afterbody is equipped with the rocket boost engine, and rocket boost engine and bottom row device are in-line arrangement; Be solidified with the high energy rocket medicine of special medicine shape in the rocket boost engine, rocket delayed firing device and end row's igniter are installed on bullet and rocket engine bottom respectively; Be 2～7 seconds the burning time of rocket boost engine.The shell afterbody is equipped with bottom row device.Bottom drainage drug is surrounded on around the rocket nozzle, forms projectile tail by bottom row device, and it is 1～2d that the shell afterbody has relative length, and the tail cone angle is 2.5～4.5 degree.
The utility model is simple in structure, reliable effect, restructuring cost are low, also for the various old-fashioned shells of repacking, gives old equipment and provides effective, the most practical, the most most economical simple and easy to do approach with new performance characterisitic simultaneously.
Concrete structure of the present utility model is referring to accompanying drawing:
Fig. 1 is 1/4 profile of extended range projectile.
Wherein: arranging device behind the 1-bullet 2-rocket boost engine 3-
Row's igniting loading amount at the bottom of the 4-centering 5-ignition device for rocket 6-
7-bottom drainage drug post 8-high energy rocket medicine 9-jet pipe
The utility model is by bullet (1), and rocket boost engine (2) and bottom row device (3) are formed.Bullet curved portions arc radius and fuse arc radius match, and bullet (1) relative length is 3.85d; Be the columnar portion that 2～7 seconds rocket boost engine (2) has been formed bullet burning time, be solidified with the high energy rocket medicine (8) of special medicine shape in it, ignition device for rocket (5) and end row's igniter (6) are installed on bullet (1) and rocket engine bottom respectively; Be surrounded on jet pipe (9) bottom drainage drug post (7) on every side with special fire-retardant, high temperature resistant, high strength covering thermosetting in bottom row device (3).
Claims (4)
1. an extended range projectile is made up of bullet, rocket engine, bottom row device, it is characterized in that: bullet curved portions radius and fuse arc radius match; Bullet portion relative length is 3d～4d.
2. extended range projectile according to claim 1 is characterized in that: shell cylinder afterbody is equipped with the rocket boost engine, and rocket boost engine (2) is an in-line arrangement with bottom row device (3); Be solidified with the high energy rocket medicine (8) of special medicine shape in the rocket boost engine (2), rocket delayed firing device (5) and end row's igniter (6) are installed on bullet (1) and rocket engine (2) bottom respectively; Be 2～7 seconds the burning time of rocket boost engine (2).
3. extended range projectile according to claim 1 is characterized in that: the shell afterbody is equipped with bottom row device.
4. extended range projectile according to claim 1 is characterized in that: bottom drainage drug is surrounded on around the rocket nozzle, forms projectile tail by bottom row device, and shell afterbody relative length is 1～2d, and the tail cone angle is 2.5～4.5 degree.
