Compared with prior art, the present invention its remarkable advantage: (1) can reduce hyper firing-rate gun subtracts rear power；(2) energy
Enough improve the firing rate of hyper firing-rate gun；(3) it can guarantee muzzle velocity consistency.
Detailed description of the invention
Fig. 1 is overall structure diagrammatic cross-section of the present invention.
Fig. 2 is that mechanical details schematic diagram is closed in opening and closing.
Specific embodiment
Structure of the invention is to install a preposition nozzle additional on the barrel that more bullets connect transmitting cannon, when the folding of jet pipe
Between and aperture structure control closed by opening and closing, open closing structure and controlled by electronic control platform according to COMPUTER PARAMETER.In bullet
Before ball transmitting, opening closing structure is closed state, guarantees air-tightness in thorax；When bullet, which is run to, presets the time, opening and closing
It closes mechanism to open in the case where platform courses are controlled electronically, for gas port by preposition nozzle and gun barrel connection, intracavitary high pressure gas is logical
Cross gas port ejection；When bullet leaves gun muzzle, opens close mechanism and closed in the case where platform courses are controlled electronically, air guide bore closure,
It is returned to pellet injection original state.
To reach design requirement, solution is as follows:
Specifically, according to mission need, when by computer according to needs and interior ballistic calculation is emitted to ignition device
Between, stepping mechanism gets into length, opens the parameters such as electric current connection time and size in close mechanism interior loop and calculated.
Specifically, according to computer calculating parameter, by electronic control platform to each hair bullet ignition charge duration of ignition into
Row control.
Specifically, according to computer calculating parameter, close mechanism is opened when by electronic control platform to each hair pellet injection
Opening and closing conjunction opportunity is controlled.
Specifically, according to computer calculating parameter, length is got into stepping mechanism by electronic control platform and is controlled.
Specifically, big to current switching time and electric current in coil by electronic control platform according to computer calculating parameter
It is small to be controlled, so that the viscosity to magnetic rheological liquid controls.
Specifically, according to computer calculating parameter, when bullet goes out thorax mouth, by electronic control platform courses cutting coil
Electric current, reset spring realize the reset for opening close mechanism
Specific embodiments of the present invention will be further explained with reference to the accompanying drawings of the specification.
As shown in Figure 1, the present invention, which is that a kind of preposition nozzle formula for more bullets series connection transmitting cannon is magnetorheological, subtracts recoil dress
It sets, including platform is controlled electronically, barrel, computer, preposition nozzle, gas port, opens close mechanism.Preposition nozzle is installed at barrel
On, jet pipe direction is parallel with barrel direction.Multiple bullet is arranged successively inside barrel.Gas port is located at when not emitting along bullet
In front of all bullets of the direction of the launch.Computer is connect with electronic control platform by signal transmssion line, electronic control platform respectively with
Electronic ignition device opens stepping mechanism in close mechanism and coil is connected.As shown in Fig. 2, opening close mechanism positioned at preposition
Jet pipe front end can move in the vertical direction, wherein when the valve mechanism for opening close mechanism is located above gas port and does not work
Valve mechanism just blocks gas port, is stepping mechanism on the outside of chamber, for controlling the length of getting into of limiting piston, in chamber
Side is limiting piston, baffle, valve mechanism are arranged successively.It is reset spring on the downside of limiting piston, reset spring presses baffle, keeps off
Plate connecting valve structure, has throttle orifice on limiting piston and baffle, and magnetorheological fluid opens closing structure chamber full of entire
Room, coil are placed in baffle, are connect by signal transmssion line with electronic control platform.
When pellet injection, electronic ignition platform first lights a fire to the gunpowder in the coyote hole of front end, and gunpowder burns rapidly
Bulk gas is generated, front end Projectile Motion is pushed.Bullet before having not arrived gas port, it is magnetorheological in conductive coil keep
It is powered, remains closed the valve of close mechanism.Open position is precalculated when bullet is run to, opens close mechanism in electronics
Control platform control is lower to open, gas port connection, and high pressure gas is sprayed by preposition nozzle in cannon thorax.When bullet goes out thorax mouth
Afterwards, coil current is cut off, valve mechanism is restored to initial position under action of reset spring.Before next hair pellet injection, line
Circle, which recloses electric current, is kept closed valve mechanism.
When second hair bullet prepares transmitting, valving is returned to closed state, whole process and the first hair bullet shooting
When it is essentially the same, the difference is that, the stroke that bullet is sent out in front and back two is different.And to keep the initial velocity of multiple bullet constant, just
It needs to control gas port opening time and aperture.Therefore before transmission, control computer is according to required transmitting frequency
The inner trajectories index such as rate, muzzle velocity, calculating have determined the duration of ignition and the parameters such as opening/closing apparatus opening and aperture.Second hair
When pellet injection, relevant operation is carried out according to calculating parameter by electronic control platform.The emission process and preceding two of third hair bullet
It is substantially similar to send out bullet, does not do and excessively repeats.
