Barrel assembly 45 shown in Figure 4 is corresponding with the frame for movement of embodiment shown in Figure 3 basically.Yet high-pressure chamber 46 is exposed to the outside of gun barrel, and is connected with low-pressure chamber 47 by the hole portion 48,49 that aligns, and hole portion 48,49 is correspondingly on the wall and afterbody cover 51 of gun barrel 50.Cutaway view as shown in Figure 5, high-pressure chamber 46 is provided with like this, promptly is arranged on snugly in the space that is limited by the adjacent wall in one group of gun barrel 45.

In addition, the afterbody cover of above-mentioned each embodiment provides relatively large cylindrical surface, and the hole fluid-tight engagement of this cylindrical surface and gun barrel is so that help prevent ignition gas to pass through between afterbody cover and gun barrel.In addition, in the embodiment shown in Fig. 2,3 and 4, the inside protuberance that afterbody puts is bonded in the groove that is formed on the housing, and a labyrinth shape sealing that runs through the inner surface of afterbody cover is provided.

In above-mentioned all embodiment, the propellant in high-pressure chamber is suitable for by the electronic ignition device igniting, and this electronic ignition device can be known from our early stage international patent application.

As shown in Figure 6, a kind ofly comprise according to typical weapon of the present invention: one group is suitable for launching howitzer 56 and is installed in barrel assembly 55 on the launcher 57, and like this, almost the howitzer of the selected quantity of blast can at a time be launched synchronously.Howitzer 56 is selectively launched by computer control from launcher 57.Weapon in this embodiment comprises 98 barrel assemblies, and each barrel assembly all comprises the howitzer 56 that stacks, and has the outside or inner propellant charge of selectively igniting.In this embodiment, launcher 57 is installed on the rotating turret 58, therefore, is run-home, and gun barrel can be around vertical or horizontal rotational shaft.

Because existing 40mm howitzer 56 can obtain, therefore be suitable for adopting 40mm howitzer 56 as projectile.Selectively from launcher 57 emissions, these launcher 57 imaginations will comprise 98 barrel assemblies to this howitzer 56 by computer control, and each gun barrel all comprises the howitzer 56 that stacks, and all has the propellant charge of selectable inside or outside igniting.Howitzer 56 can be launched selectively, forms the array that hits of controllable blast howitzer in the survey area.

Mode by this embodiment, the barrel assembly of employing in the launcher of 98 40mm gun barrels can be measured the section zone of approaching 350mm * 700mm, the every gun barrel that is adopted is equipped with six emission bullets, each projectile is all similar to the size of the military howitzer of 40mm, needed barrel length is 900 millimeters, and this barrel assembly provides the capacity of 588 projectiles.This configuration is suitable for use in needs short-range seismic survey, as is used for from the gun barrel emission projectile towards the below.For long-range emission minority projectile, can in each gun barrel, adjust projectile, or adopt long gun barrel and adopt more propellant, go out speed to guarantee the higher muzzle of projectile.

The maximum fire rate of estimating each gun barrel is per minute 20000 emission bullets.Therefore, suppose all gun barrels synchronized transmissions when maximal rate, the maximum fire rate of 98 gun barrels combining is per minute 1960000 emission bullets.

For the first circle 98 emission bullets from 98 gun barrel emissions, huge variation takes place in its speed, can be to launch 98 emission bullets with the frequency that is exceedingly fast.

The launcher of above-mentioned 98 gun barrels is examples in the present available particular characteristic scope.Different performances can realize by the parts that change launcher.For example, launcher can load in advance so that change between the single gun barrel of launcher or the characteristic and the weight of explosive in a gun barrel and/or projectile.

A plurality of such launchers 57 can be installed and be arranged on the vehicle, and therefore, each launcher 57 can selectively point to a needed target and launch with selected speed.Selectable, launcher 57 can be jointly to same target emission.

In the embodiment shown in fig. 7, howitzer 56 is launched downwards from a pair of such launcher 57, only shows one of them of being carried by helicopter 58 among the figure, has formed the blast concentrated area on ground.This blast density and can be controlled by control variables by the earth coverage area territory that forms of blast is as the speed of emission rate, the elevation angle and aircraft.

Six such launchers 57 in the housing 61 of its each fuselage 63 sides, have been carried below the wing 62 at the unmanned dirigible 60 shown in Fig. 8 and Fig. 9.Imagine each launcher and can comprise that six 40mm howitzer launchers, each launcher have 100 barrel assemblies and have six howitzers in every gun barrel.To provide 7200 howitzer loading capacities corresponding to 3600 pounds destruction packages.

In this embodiment, the aiming that accommodates the gun barrel of howitzer 56 will realize that this aircraft can carry video camera or similarly install the Long-distance Control of assisting from the operator by the remote control of aircraft.

Figure 10 illustrates this projectile launch frame 70, and only show two barrel assemblies 71 of described type with cutaway view, this barrel assembly 71 is contained in the rectangular launcher casing 72 at certain intervals, and hangs installation from upper wall 73 and corresponding spherical bearing 74.

Each barrel assembly 71 extends downwards to align control device 75 by fixing spherical bearing 74, control device in this embodiment can be respectively or is controlled barrel assembly 71 selectively, be used for barrel assembly is moved to the obliquity of described normal vertical position one side or opposite side, or move to the front or rear position of normal vertical position, if desired, can move to the block position of these states.

For realizing this purpose, each barrel assembly all is provided with a cylindrical locating piece 78, and this locating piece 78 is rotated support around its lower end, is used to make its eccentric axis that centers on each barrel assembly motion.A midfeather with holes 80 closely holds each cylindrical locating piece 78.The vertical position of midfeather 80 is by first hydraulic jack 81 control in other words of vertical hydraulic oil cylinder, and the base plate that vertical hydraulic oil cylinder 81 is supported on launcher casing 72 is in other words on the pedestal 82.

The stretching out and/or withdraw in the vertical direction is moved midfeather 80 of vertical hydraulic oil cylinder 81, by the constraint of corresponding hole, it is moved along fixed axis, therefore, in described barrel assembly, because midfeather 80 moves downward, the bottom of barrel assembly 71 will move inward towards another barrel assembly mutually, because the fixed intervals of last spherical bearing 74 make barrel assembly outward-dipping corresponding to another barrel assembly mutually.

Therefore, as can be seen, by the location of control vertical hydraulic oil cylinder 81, barrel assembly can be with the vertical and parallel attitude location of its axis, perhaps tilt with respect to vertical direction with its axis and parallel attitude location, perhaps the mode that is in a certain lateral attitude with its axis is located.

Each locating piece can rotate around the lower end of barrel assembly selectively, this lower end is by the flexible installation of second hydraulic jack 84 in other words of horizontal hydraulic pressure oil cylinder, and horizontal hydraulic pressure oil cylinder 84 is supported on the midfeather 80 and in the lateral wall of corresponding locating piece 78 and extends a track 83.This track is to be provided with like this, and the normal vertical motion of midfeather 80 will can not cause that locating piece 78 rotates in the direction of arrow 85, unless horizontal hydraulic pressure oil cylinder 84 stretches out or withdraws.

As can be seen, vertical hydraulic oil cylinder 81 is connected with midfeather 80, on all barrel assemblies, concur so that when each horizontal hydraulic pressure oil cylinder 84 that is used for each barrel assembly 71 is provided, barrel assembly can and harmonic motion.

These horizontal hydraulic pressure oil cylinders 84 can not rely on vertical hydraulic oil cylinder 81 and independent control.Like this, for example, on the other hand, this locating piece 78 shown in the accompanying drawing is arranged relatively prejudicially corresponding to barrel assembly 71, one of them can rotate 780 degree by its horizontal hydraulic pressure oil cylinder 84 locating piece, so that make hydraulic pressure locating piece 78 and its axis parallel to each other, and has identical side-play amount with respect to the axis of barrel assembly 71.

In this was provided with, the work of vertical hydraulic oil cylinder 81 can be rotated barrel assembly to a side synchronously, or turned to other position from vertical position, at this moment, in the centre position with respect to certain a positioning block 78 of another locating piece, can realize the inclination of barrel assembly.Certainly, horizontal hydraulic pressure oil cylinder 84 and vertical hydraulic oil cylinder 81 can both be by driven in synchronism and by suitable controller 86 control, be implemented in the target direction marked change and from the dispersion of this emission projectile drop point.In addition, hitting being provided with of characteristic can change in the zone that sets.This barrel assembly also can be controlled to provide a limited number of rotating turrets, to realize projectile group's great depth density.

As can be seen; at the projectile launch frame remote controllers 86 can be installed; these remote controllers 86 can be from being installed on the barrel assembly or the parts relevant with barrel assembly or oil cylinder position receive the alignment sensor of information; can launch and very rapidly be distributed to objective apace; even objective can be on an aspect; after this, with the inclination angle remote control emission projectile with respect to vertical position normal or that change, to be implemented in the regional needed drop point of being hit by a bullet.The size of figure of being hit by a bullet can be change or remain on a constant with the different target distributed areas.

The drive unit that is used for rotating locating blocks 78 can not rely on midfeather 80, as has device of rotation driving flexible or that spline connects, and this device drives the pedestal of barrel assembly.In addition, base plate pedestal 82 in other words can maybe can be to be raised up to a certain obliquity to sidewall slope, and is final so that the approximate inclination angle in head for target zone to be provided, and realizes the Long-distance Control aiming by direction-control apparatus 75.

As shown in figure 11, it is to launch a kind of selected projectile array that a kind of typical case of above-mentioned launcher uses, by the projectile from the emission of same launcher, with knocking fuel/air cloud that the method that becomes control and pattern form a kind of qualification, this projectile holds the fuel that scatters from this projectile.

For example, the fuel that holds projectile can form a kind of fuel/air mixture cloud 90 that is roughly cone shape, and explodes and can take place synchronously from the some positions 91 around conical top, has formed a concentrated demolition point that points to required target 92.

The size of fuel/air mixture cloud 90 and weight can be chosen to be and make the emission high-pressure shocking wave to locating area.These can be owing to the mine fields that detonate a mine, as a kind of fatal land mine that prevents artificial destruction, or the blast that provides a kind of non-lethal that prevents ground forces to destroy by the fuel/air mixture cloud 90 that rises.

Only the mode by the above embodiment of the present invention has provided top content, to those skilled in the art, all variations and modification to foregoing are considered to all drop within scope of the present invention and the boundary, and are limited by additional claims.
