Definitions

  • the invention relates to a device for reducing or damping the shock wave that occurs when a shot is fired at the mouth of the barrel of barrel weapons according to the preamble of claim 1.
  • muzzle brakes were used, if necessary, which have the task of reducing the recoil force of the weapon.
  • the shock wave that forms in the area of the muzzle causes a force against the recoil of the weapon and a reduction of this shock in the muzzle brake.
  • the explosive shock wave dynamically loads the structure of the gun.
  • the shock wave causes considerable noise pollution.
  • special ventilation must be provided for the discharge of the shot gases escaping at the mouth of the weapon barrel, even if the weapon barrel mouth flows around in rapidly moving vehicles, such as aircraft.
  • the object of the present invention is both the reduction of the shock wave load and the reduction of the weapon recoil force as well as the derivation of the shot gases from sensitive parts of the aircraft.
  • the device contains the weapon barrel 6, at the front end of the weapon barrel a muzzle brake 4 and, in connection therewith, the device 5 according to the invention, referred to below as a shock wave accumulator.
  • the longitudinal axis of the gun barrel is designated by A and the weapon barrel muzzle by 7 .
  • the weapon barrel 6 is accommodated in the weapon in the usual manner by means of bearings, not shown here.
  • the device according to the invention is combined here, for example, in connection with the muzzle brake 4 , of a known type. However, the device can also be used without such a muzzle brake or a muzzle brake in a construction that differs from the illustration in FIGS. 1 to 3.
  • the muzzle brake 4 is formed by a sleeve 12 on the front End of the gun barrel 6 is placed and fastened, the sleeve portion 12 ′′ projecting beyond the gun barrel end 7 .
  • the sleeve section 12 ' has, on the circumference and in the direction of the barrel longitudinal axis A , passages 18 and 18' which connect the space 8 in front of the weapon barrel end 7 to the interior of the device.
  • the sleeve part 12 ' also carries deflecting blades 16 which extend bell-shaped over part of the passages 18' .
  • the front weapon barrel end 7 with the sleeve part 12 'of the muzzle brake 4 are enclosed by a sheath tube 30 forming the shock wave accumulator 5 , which is firmly screwed to the sleeve 12' of the muzzle brake 4 by means of thread 31 and mating thread 32 .
  • the cladding tube 30 belonging to the shock wave accumulator 5 is supported on the rear by means of bearing webs 21 on the weapon barrel 6. Furthermore, a front and a rear weapon barrel bearing 9, 9 ′ are provided between the weapon barrel 6 and the envelope barrel 30 .
  • the cladding tube 30 forms with the bearing 9 an annular space 35, which is arranged to receive discharge tubes 36 arranged in the weft direction S R , which are distributed over the circumference of the annular space 35 concentrically to the weapon tube 6 .
  • the discharge pipes 36 are curved in such a way that they point to the rear (counter to the firing direction S R ) and by an angular amount to the outside in accordance with the discharge direction denoted by A R.
  • the tube bundle with the tubes 36 is held in the area of the tube outlet openings 39 with respect to the cladding tube 30 by means of a support 33 .
  • the discharge pipes 36 have, at a certain distance from their inlet opening 39 ', a constriction 37 with a section 38 correspondingly reduced in diameter.
  • the pipe constrictions 37 are designed with different distances from the inlet openings 39 ' in the annular chamber 35 with respect to the longitudinal extent of the pipes 36 .
  • the different distances between the pipe inlet 39 ' and the constriction 37 are achieved by the different radii of curvature of the discharge pipes 36 for the discharge of the shock wave S W to the side and counter to the direction of fire S R to the rear.
  • the tubes 36 or the constrictions 37 at different distances. As a result of the differences in distance between the inlet openings 39 'of the tubes 36 and the constrictions 37 , the delay in the shock wave path on the way to the outlet openings 39 is staggered and thus a short-term storage is effected.
  • the discharge pipes 36 open with their inlet opening 39 ' into the chamber 34 formed by the cladding tube 30 , which in turn are connected via the passages 18 and 18' to the interior 8 of the sleeve 12 ' and 12''in front of the weapon barrel end 7 .
  • the mode of operation of the device according to FIGS. 1 to 3 is as follows:
  • the shock wave S W that forms when the shot is fired in the muzzle chamber 8 in front of the weapon barrel end 7 is introduced into the chamber via the passages 18 and 18 ′ and with the aid of the deflecting blades 16 against the firing direction S R 34 of the cladding tube 30 and from there via the discharge pipes 36, the constrictions 37 and the pipe sections 38 to the outlet openings 39 .
  • the shock wave is split into the individual pipe parts by means of the discharge pipes 36 and deflected to the rear and to the side.
  • the shock wave W S is stored by means of the narrowing 37 of the drain pipes 36 for a short time or delayed and differently delayed via the openings 39 of the tubes 36 is derived to the outside.
  • the cladding tube 30 (30 '') itself has a scoop-shaped, curved wall 17 at its end lying in the weft direction S R , so that the shock wave entering the cladding tube chamber 34 through the passages 18 is counter to the weft direction S R is deflected as a second deflection stage to the inlets 39 'of the discharge pipes 36 .
  • a rear complete closure of the cladding tube 30 or the cladding tube chambers 34, 34 ' is provided, the shock wave deflected counter to the firing direction S R at deflection means at the rear end of the cladding tube 30, 30'. reflected back in the firing direction S R and passed via the deflection blades 16, 17 and the passages 18 and 18 ' into the muzzle space 8 in front of the weapon barrel muzzle and is released into the environment via the projectile outlet 13 .
  • the cladding tube 30 is extended to the rear bearing 42 and is mounted on the weapon barrel 6 via the bearing 42 .
  • the bearing 42 is mounted in the bearing 42 by means of radially movable abutting bearing rings 43 , which reduces overdetermination of the bearing between the cladding tube 30 and the weapon barrel 6 .
  • Two sections 30 ′ and 30 ′′ are formed by the cladding tube 30 , which have chamber sections 34 and 34 ′ .
  • the cladding tube is supported on the weapon barrel 6 between the section 30 ′′ and the section 30 ′ via a bearing 40 with radial webs 41 , in order to maintain the connection of the chambers 34 and 34 ′ .
  • the mode of operation of the device according to FIG. 4 is described as follows: When firing a shot, as in the embodiment according to FIGS. 1 to 3, the shock wave S W from the mouth space 8 of the sleeve part 12 'in front of the weapon barrel muzzle 7 via the passages 18 and 18' and the blades 16 and 17 of the first and the second deflection stage of the chamber section 34 of the cladding tube 30, 30 ' in the direction of the cladding tube end in the region of the bearing 42 counter to the firing direction S R.
  • the shock wave S W is reflected back in the weft direction S R after passing through the entire cladding tube 30 and via the deflection blades 16, 17 and the passages 18 and 18 ' to the sleeve part 12' to the muzzle space 8 of the gun barrel 6 and derived via the sleeve part 12 '' to the front.
  • the described redirection of the shock wave S W that is to say the double distance within the cladding tube 30, 30 ′, 30 ′′, results in a short-term storage or delayed discharge of the shock wave S W and thus a reduction in the shock intensity.
  • the rear end of the cladding tube 30 instead of the bearing rings 43 has an end cap 50 which is either fixedly connected to the cladding tube 30, 30 'and or to the weapon barrel 6 by means of locking pins 53 .
  • the end cap 50 has a concave inner wall 51 facing the section 34 'of the cladding tube chamber for the reflection of the shock wave S W starting against the firing direction S R when the shot is fired.
  • the formation of the inner wall 51 of the end cap 50 can also be made convex or conical in both directions of the longitudinal axis A.
  • a hose line 60 made of flexible material is provided at the rear end of the cladding tube 30 (30 '), which leads on the one hand into the cladding tube chamber section 34' and on the other hand into the open air.
  • the hose line 60 is fastened to the structure 61 of the gun by means of fastenings 62 and to the cladding tube section 30 ′ of the cladding tube 30 using the fastener 63 .
  • the connection between the cladding tube section 30 ′ and the surroundings, which is designed as a flexible hose line, can also be designed as a fixed tube without attachment to the surrounding structure.
  • the operation of the design according to FIG. 6 is the same as the design according to FIG. 5 with the difference that the vent pipe 60 enables a faster pressure reduction in the interior 34 'of the cladding pipe 30 .
