Abstract
A method and a device for the launching of a projectile is disclosed. A front and aft plate are coupled to an expansion vessel having an axis so that when the volume of the expansion vessel increases the pistons move in opposing directions along the axis. A projectile is so disposed that it is launched in a desired direction by the motion of the front plate. The motion of the plates along the axis is limited in that the two plates are connected to each other by an extendible coupling structure.
Description
Technical background
Under many tactics sights, particularly in the city, do wartime, it is very important reducing the feature that interrelates with the emission projectile.When emission projectile from the pipe that has rocket engine, the gas of discharge produces a higher-pressure region and can observe the tangible sense of hearing and visual signature.This has just got rid of from blindage and carries out the possibility of hidden shooting and make that the ejaculator is easy to be detected.
For reducing bad influence recited above, people have designed a kind of emission system of sealing.This system is limited in the gaseous product of propeller burning between two pistons that move in the opposite direction in the transmitting tube.Schnabels etc. are at U.S. Patent application US 3,771,417 and US3, disclose a kind of emission system of pulling the trigger projectile in 779,130, and this system is famous two " catching piston " design.One of piston promotes and quickens projectile along transmit direction, and another piston promotes a reverse group of moving until its injected going out along direction backward.Two pistons move till it moves to the front-end and back-end machinery halt of transmitting tube always.Even this system mates in the weight of propellant both sides very much, may on two pistons knock time of halt, not match yet, thereby cause the generation of recoil, thereby influence the degree of accuracy and ejaculator's safety.
In addition, because impact endways has been transferred to transmitting tube by piston, transmitting tube must withstand this impact tension force on structural design, and this makes the weight of transmitting tube have to increase.
Moreover, in design, be necessary brake apparatus in conjunction with a kind of distortion, disclosed like that at U.S. Patent application US 4,148,244 such as Schnabel etc., such device has increased the complexity of design and the weight of emission system.
The invention provides a kind of solution that is used to contain the gases at high pressure product of propellant combustion,, also can not produce recoil without the axial loading transmitting tube.
Summary of the invention
According to the present invention, projectile is launched from transmitting tube after being promoted by a plate that can be used as a piston.And another plate that can be used as a piston is launched away until this group along the oppositely mobile group of direction promotion one backward.Oppositely the group of moving is made of the flowable media with suitable high concentration.Two plates are interconnected, and the structure of two side plates of this connection makes the distance between two plates just stop two plates to move when reaching the predefine value again.In one embodiment, interconnect architecture is airtight, as to include two gases between a side plate telescoping tube, and transmitting tube can not be subjected to high pressure at all.In another embodiment, interconnect architecture is many ropes, and gas is accommodated in as the transmitting tube of pressure vessel with as between the side plate of piston.

Fig. 2 b is the emission system schematic diagram behind the emission projectile according to second embodiment of the invention.
Preferred embodiment
Fig. 1 has represented the first embodiment of the present invention.Emission system comprises that two ends have droppable transmitting tube 1 after the use of removable lid 2,3.Optical sight 4 and firing lock 5 are attached on the transmitting tube 1.The output of firing lock (electronics or pyrotechnics) by an electronic conductor or pyrotechnics hawser (as, lead quick-fried type pyrotechnics rope) 6 send propeller ignition system 7 to.Propellant 8 is closed in as between two side plates 9 of piston and 10.
Projectile 11 is put in the front of front side board 9, and reverse mobile cumularsharolith is in the back of side plate 10.Oppositely the group of moving can be the flowable media with suitable high concentration.Biside plate 9 and 10 is connected to each other by an open syndeton 13.Syndeton 13 is made of several ropes making with the high-tensile strength material or hawser, and the high-tensile strength material can be strong steel or strong fiber as Kevlar fabric or the combination of the two.If nonmetal, the last layer insulating materials can be coated with, on rope or hawser as rubber.When the ejaculator started firing lock 5, a signal sent propeller ignition system 7 to.Propellant 8 is lighted and is burnt, thereby produces high temperature, gases at high pressure.The pressure that in transmitting tube 1, produces and as the pressure collision that produces between the side plate of piston 9,10 on piston.Projectile 11 is promoted forward by side plate 9, launches away from transmitting tube 1 subsequently.Oppositely the group of moving 12 is promoted backward by side plate 10 and scatters after leaving transmitting tube 1.
The distance of structure 13 between two plates of two side plates of connection just stops two plates to move when reaching the predefine value of being determined by the tension force of rope again.The length of rope or hawser can be the same, and also difference slightly also can be different on thickness, thereby make the prevention of piston to stretch to certain time interval, and can not stop suddenly.
For the dispersion that helps the reverse group of moving with progressively discharge pressure between the projectile launch back side panel, on piston, several openings 14 can be arranged, as hole or explosion vent.
Fig. 2 has represented the second embodiment of the present invention.Do not show in Fig. 2 with components identical embodiment illustrated in fig. 1 and mark.Identical part can be with reference to figure 1.Emission system comprises that two ends have droppable transmitting tube 1 after the use of removable lid 2,3.Optical sight 4 and firing lock 5 are attached on the transmitting tube 1.The output of firing lock (electronics or pyrotechnics) by an electronic conductor or pyrotechnics hawser (as, lead quick-fried type pyrotechnics rope) 6 send propeller ignition system 7 to.
Projectile 11 is in the front of front side board 9, and reverse mobile cumularsharolith is in the back of side plate 10.Oppositely the group of moving can be the flowable media with suitable high concentration.When the ejaculator started firing lock 5, a signal sent propeller ignition system 7 to.Propellant 8 is lighted and is burnt, thereby produces high temperature, gases at high pressure.The pressure collision of pressure that produces in telescoping tube 23 and generation between side plate 9,10 is on side plate.Projectile 11 is promoted forward by side plate 9, launches away from transmitting tube 1 subsequently.Oppositely the group of moving 12 is promoted backward by side plate 10 and scatters after leaving transmitting tube 1.
The distance of telescoping tube 23 between two plates of two side plates of connection just stops two plates to move when reaching the predefine value of being determined by the extended length of telescoping tube again.Except that telescoping tube connects, also can add with some powerful ropes and connect biside plate, thereby make the prevention of side plate to stretch to certain time interval, and can not stop suddenly.
For the dispersion that helps the reverse group of moving with progressively discharge pressure between the projectile launch back side panel, on side plate, several openings 14 can be arranged, as hole or explosion vent.
