The specific embodiment
With reference to accompanying drawing, should be realized that the present invention can realize with the variety of way and the purposes of multiple projectile.For example, the present invention can provide single projectile, comprises the weapon of projectile or be used for inserting weapon and barrel assemblies that comprise stacked projectiles.
Embodiment described here relates to the urgent slap shot bullet that bore reaches 60mm, it should be understood that the present invention can use various projectile configurations.Particularly, the inventor's the disclosed projectile configurations of previous patent application, it is suitable for axially being stacked in the barrel assemblies and is configured to be suitable for being launched continuously by electronic unit.
Figure 1A shows the projectile with main body 10, and this main body 10 has front portion 11 and rear portion 12, and described projectile is suitable for similar projectile with other and is stacked in the gun barrel together.Described projectile mainly includes imitates load 13, and this payload can be all kinds, for example explosive, flash fireworks, cigarette or artillery fire retarding agent.Advance ammunition 14 to be contained in the hole in the projectile and can optionally ignite, though can use the wired or wireless ignition system of leading of a cover by separately initiator 15, the sensing element that is preferably semiconductive bridge (SCB) and so on.Ammunition is contained in the hole in the embolism 16, and this embolism for example can be with being threaded or being adhesively fixed.The mouth 17 that is located at described front portion is used to discharge the gas that ammunition burning produces.In this example, described mouth is being opened forward and leading adjacent projectile is being released from gun barrel.And this projectile is advanced by the ammunition in the adjacent projectile of back conversely or the ammunition of gun barrel substrate advances.Described front portion is preferably shaped to the rear portion of adaptive described leading projectile, and similarly, this rear portion is configured as the front portion of adaptive back projectile.This provides sealing to a certain degree and can obtain by the whole bag of tricks between projectile.
Figure 1B and 1C are the end-view of projectile shown in Figure 1, and it shows front and rear.Schematically be provided with four around the longitudinal axis of projectile and advance ammunition 14, they keep also correspondingly being provided with four mouths 17 that are used to discharge burning gases by four embolisms 16.The number of ammunition and configuration can change the purposes with adaptive particular projectile.But it should be noted that the flight characteristics that when selecting and lighting ammunition, can change projectile, unless before the gun barrel emission, light all ammunitions at projectile.For example, the barycenter of projectile can change.
Fig. 1 D shows two, and to send out projectile this be how to be stacked in the gun barrel.The front portion 11 of back projectile cooperates the rear portion 12 of leading projectile, and rear portion 12 is expand into the gun barrel inner seal contact.In this example, the convex surface of described front portion mates the concave surface at described rear portion, and described rear portion also comprises edge 18, the main body of this EDGE CONTACT back projectile.Thereby one or more ammunitions of back projectile are chosen and light and will take the lead projectile with required kinetic energy and release from gun barrel.In case should leave by leading projectile, thereby all ammunitions that remain in the projectile of back are just lighted predetermined weight and the barycenter of generation in the projectile of back, the projectile of this back has become leading projectile now.So every emission bullet has rational standard and predictable flight characteristics.
How the last projectile that Fig. 1 E and 1F show in this projectile of a pile is launched.Advance ammunition 14 can be arranged on the gun barrel substrate, this substrate is the independently detachable element 19E of gun barrel self or fixing element 19F.The mode of ammunition is received and lights ammunition 14 in each of these accompanying drawings in the projectile to be similar to.Described separate substrate element 19E preferably was loaded in before projectile below the gun barrel, and anchoring base element 19F then is that ammunition wherein can be used as from the noncontinuous item at gun barrel rear portion and is loaded simultaneously.These ammunitions can be chosen and emission predetermined kinetic energy is offered last projectile.
Fig. 2 A shows the projectile that another kind has main body 20, and this main body has front portion 21 and rear portion 22, and if desired, described projectile is suitable for being stacked in the gun barrel together with other similar projectile.Described in this example projectile comprises payload 23.Advance ammunition 24 to be contained in the hole in the projectile and optionally ignite, though can use the wired or wireless ignition system of leading of a cover by separately initiator 25, the sensing element that is preferably semiconductive bridge (SCB) and so on.Ammunition is contained in the hole in the embolism 26, and this embolism for example can be with being threaded or being adhesively fixed.The mouth 27 that is located at described rear portion is used to discharge the gas that ammunition burning produces.In this example, described mouth is being opened backwards and projectile is separately being released from gun barrel.Described front portion is preferably shaped to the rear portion of adaptive described leading projectile, and similarly, this rear portion is configured as the front portion of adaptive back projectile.This provides sealing to a certain degree and can obtain by the whole bag of tricks between projectile.
Fig. 2 B and 2C are the end-view of the projectile shown in Fig. 2 A, and it shows front and rear.Schematically be provided with four around the longitudinal axis of projectile and advance ammunition 24, they keep also correspondingly being provided with four mouths 27 that are used to discharge burning gases by four embolisms 26.The number of ammunition and configuration can change the purposes with adaptive particular projectile, but it should be noted that the flight characteristics that can change projectile when selecting and lighting ammunition.For example, can change the weight and the barycenter of projectile.On the other hand, outlet backward can not produce resistance.
Fig. 2 D shows two, and to send out projectile this be how to be stacked in the gun barrel.The front portion 21 of back projectile cooperates the rear portion 22 of leading projectile, and rear portion 22 is expand into the gun barrel inner seal contact.In this example, the convex surface of described front portion mates the concave surface at described rear portion, and described rear portion also comprises edge 28, the main body of this EDGE CONTACT back projectile.It being understood that in all projectiles described here and can have shape and size widely.Each projectile is released from gun barrel with lighting thereby the one or more ammunitions in every emission bullet are chosen with required kinetic energy.The predictable flight characteristics of described projectile is generally than lacking among Figure 1A.
Fig. 3 A shows in detail the typical propellant charge 14 or 24 among Fig. 1 and 2.Ammunition material 300 is contained in the metal shell 301, and an end 302 complete openings and the other end 304 of this housing have less hole 303.The disk 305 that composite is made can be with hole 303 sealing, but one light ammunition material and will destroy sealing, and burning gases pass hole 303 and enter separately outlet like this.In this example, based on the SCB igniter, initiator 306 is screwed into or presses fit in the end 302.Initiator comprises the SCB307 in parallel with coil 308, and for example they all are installed in the plastic fittings 309.Thereby small amount of pyrotechnic material 310 is served as pro-knock agent around SCB in ammunition burning.Many other structures can be used for advancing ammunition and are used for initiator, for example also this ammunition directly can be introduced in the hole in the projectile and be need not housing 301.
Well-known semiconductive bridge has the outward appearance of the microchip described in picture US4708060 and subsequent the United States Patent (USP), and this semiconductive bridge has two terminals.If these two terminals have electrical potential difference, semiconductive bridge just discharges less energy, and major part is the form of heat.The energy that SCB discharged may be not enough to the propelling ammunition is directly lighted in some cases, the compound that initiator may also need to dispose (also promptly, the compound that can be lighted by SCB, and this compound will be lighted ammunition).SCB can be designed and be arranged so that the electric current of being responded between described two terminals can promote energy to discharge.Consider that those skilled in the art know very much and utilize magnetic field (induction) faradic various parts in coil, therefore needn't describe this details here, save an example.So all these parts that suitable emission current is provided are all fallen within the scope of the invention, no matter be by responding to described electric current or other.
Fig. 3 B schematically shows the induced emission system that can be used to launch projectile shown in Fig. 1 and 2.Can utilize the signal transmitting coil 33 that is wrapped in around the gun barrel 30, be suitable for responding to the magnetic field that is suitable for activating SCB near projectile 31, also, one of them transmitting coil or first coil, 33.1,33.2 grades are used for every emission bullet 31.1,31.2 etc.Electric current in first coil 33 can optionally be connected or be closed by emission controlling unit (FCU) 39, therefore can control resulting electric current in the receiving coil or second coil 35.1,35.2 in a like fashion.First coil can independently link to each other with FCU or connect.FCU can in all sorts of ways operation so that select kinetic energy and therefore light ammunition for next projectile that is about to emission.The user uses the hand operated rotary switch, and this switch indicates 1,2 concisely, and 3... or all ammunitions will soon be lighted.User or automatic transmitting system are determined the kinetic energy that particular projectile is required according to its residing environment.
For in the projectile (for example projectile 31.2) of appointment with ammunition igniting, the FCU39 electric current that will transmit offers first coil 33.2 around the gun barrel 30 that is wrapped in projectile 35.2.The magnetic field induced-current in second coil 35.2 that generates, this electric current is provided for initiator 32,33,34 two terminals.One or more propelling ammunition 36a, 36b, 36c is configured to transmit with regard to the initiator of lighting and light receiving in response to those.
SCB also can be designed to like this, and promptly SCB is because single electric current but only can not light when the electric current of specific " type " generation.In fact, the SCB technology has the ability of making SCB now, and this SCB needs the igniting signal of various different-energy grades to activate high energy material.If desired, encoder also can be used in combination with the SCB technology.Under the situation of using encoder/decoder and other logic circuit, signal modulation scheme can comprise any pulsewidth modulation (PWM), pulse code modulation (pcm) or pulse-amplitude modulation (PAM) scheme, perhaps any encoding scheme that other is fit to.This makes that independent, less propelling ammunition 36 is lighted 33,35 discretely via shared induction coil.
We begin to consider for example to adopt the variation of electric current to insert igniting signal now.For the propelling ammunition 36a igniting with (or any specific) projectile 35.2 usefulness of appointment, FCU39 offers first coil 33.2 related with this projectile with electric current (wherein inserting suitable modulation variable).The intensity of resulting electric current (passing through magnetic field induction) therefore changes pro rata with the electric current variable that FCU provides in second coil 35.2.Therefore, pass to the induced-current of SCB also along with the variation of magnetic field intensity changes pro rata.Like this, by using the single induction coil 33 of every emission bullet, the proprietary SCB32 among the propelling ammunition 36a of projectile 35.2 can be transmitted suitable code signal, and therefore is initiated under the situation of not lighting propelling ammunition 36b or 36c.
It being understood that one lights selected one or more propelling ammunitions 36, the rapid burning of this ammunition makes related projectile discharge from gun barrel 30.Only cause one at SCB33 and advance ammunition for example under the situation of center ammunition 36b, the kinetic energy that passes to projectile will be significantly less than all three kinetic energy that transmitted when advancing ammunitions to be lighted.
Fig. 4-8 shows the projectile with projectile body 46 45 of another embodiment of the present invention, and this projectile body has hole 49, and wherein a plurality of propelling ammunitions 50 vertically are arranged in this projectile.On the contrary, the propelling ammunition of the foregoing description is horizontally installed in the projectile.For reason clearly, initiator and second or receiving coil from accompanying drawing, save.
Because the diameter of propellant cavity diminishes towards the head 47 of projectile, if the first loading seal disc 51 is pushed to the head 47 of projectile, between the band edge in hole 49 and the conical inboard wall wedging action will take place, described disk will make top ammunition 50.1 be maintained fixed.Correspondingly, when directive force like the application class in emission process, for example be initiated second when advancing the power that ammunition 50.2 burnings are produced, seal disc 51 will further wedging be fixing by described inwall 56.This " wedge-sealing " acts on and is intended to reduce the possibility that advances ammunition 50.2 to light, because lighting of this propelling ammunition can make that 50.1 companions of propelling ammunition are lighted or " gas blowby (blow-by) " lights.
Yet, advance the adjacent seals band that will advance on other direction of lighting of ammunition 50.1, thereby this band opened and pushed it against the afterbody 48 of projectile 45.Seal disc 51 will be no longer mobile leave the cooperation inwall 56 in hole at its edge before, allow burning projectile 50.1 to touch the propelling ammunition 50.2 of back thus.Like this, the propelling ammunition 50.2 of Lin Jin back is lighted and this process continues rapidly until advancing ammunition 50.4 to be lighted.In brief, the propelling ammunition that will can not make near this projectile front portion of lighting of particular propellant charge 50 is lighted, as mentioned above.
Fig. 5,6 and 7 show the result who lights the selected propelling ammunition in the projectile 45.In Fig. 5, the 3rd advances ammunition 50.3 to be lighted, impels ammunition 50.3 and 50.4 burnings thus.In Fig. 6, second advances ammunition 50.2 to be lighted, impels ammunition 50.2,50.3 and 50.4 burnings thus.In Fig. 7, first advances ammunition 50.1 to be lighted, impels all to advance ammunition burning thus.
Described hole comprises the parts that prevent that seal disc from discharging from the hole, and these parts are a plurality of finger pieces that inwardly radially extend or in order to braking or prevent that at least seal disc 51 from discharging or leaving the retaining point 57 of projectile cavity 49 (shown in Fig. 4-8) fully.Be provided with several little retaining points 57 around the hole 58, this as can be seen from Figure 8.Preferably, thus described retaining put ground, the described hole of complete crosscut and stretch out and guarantee disk and be contained in the projectile for the form of cross bar.In another form, wall elements or seal disc can be made of combustible material, and its outer surface is processed to prevent burning, and also, the burning of propellant only causes burning in the place ahead of wall elements.
Because the retaining point can or cannot manufacture the part of projectile expediently, so retaining point 57 can form independent component 59, advanced ammunition 50 and seal disc separately in case hole 49 loads onto, this individual components for example by cooperation screw thread (not shown) with regard to removably remain on rear portion 48 '.Fig. 9 shows the modification of this element of the 4th embodiment.
In another modification, the whole hole 49 that comprises metapore 58 can form individual components and also equally removably remain in the projectile body 46.Selectively, the independent component that contains the hole can be formed with the propelling ammunition of landscape configuration mentioned above and expansion bleed ports separately.
Figure 10 and 12 (saved once more initiator and second or receiving coil) shown in the fifth embodiment of the present invention in, projectile 60 comprises wall elements 61, and this wall elements itself is screwed into its position respectively via the inwall of cooperation screw thread 62 set on the wall member edges and projectile cavity 63.In addition, as shown in figure 10, each wall elements 61 comprises gland cock 64, and the sealing embolism is wedged in the wall elements in the mode identical with above-mentioned seal disc.
Gland cock 64 is equipped with little T type keeper 65, and this keeper is braked or prevented that at least this embolism from leaving projectile cavity 63 fully.Think that at present gland cock 64 need be manufactured into two workpiece (also promptly, embolism and keeper) and assembling on the spot.In the mode identical with above-mentioned the 4th embodiment, T type portion is made up of several little retaining points, rather than utilizes whole circle to form.But, in the present embodiment, retaining point be a plurality of extend radially outwardly be the finger piece 66 of crisscross configuration a little.Similarly, as described above, when its separately wall elements 61 of T type spare 65 bump, it can not block and advances ammunition 67 to arrive projectiles 60 outsides, shown in the amplification view of Figure 11.
Should be taken into account that at present T type keeper 65 only needs the screw-in wall elements 61 at the most close projectile rear portion.Figure 12 shows the final result of lighting top propelling ammunition 67.1 in this case.Independent propelling ammunition 67 can only utilize the induction coil of every emission bullet (shown in figure Figure 1A and the 1B) and be lighted, and wherein the SCB of different coding is used for each propelling ammunition 67.1,67.2,67.3 etc.Correspondingly, need four kinds of different codings response SCB in the example of the 5th embodiment shown in current.
The above embodiment of the present invention all needs to use independently (and general volume is less) propelling ammunition.Usually, the operator can determine or automatic transmitting system can determine to burn available propellant 1/4,1/2,3/4 or all propellants that can use particular projectile.But, it being understood that to advance the volume of ammunition to be cut apart by this way, and in fact available any mode of wanting is cut apart.
In Figure 15 and 16, show the element of the projectile assemblies of type described in the applicant's the international patent application NO.PCT/AU/00932.Previous invention is about stage by stage or the successively-ignited a plurality of propelling ammunitions related with every emission bullet, thereby reduces the pressure in the gun barrel in emission process when keeping projectile initial velocity.
The applicant recognizes that the present invention also can obtain described other application about the 6th embodiment now.Here, each projectile assemblies 80 comprises projectile body 81, the afterbody 83 that this main body has head 82 and extends back, and this afterbody has tapered edge 84, as shown in figure 15.Projectile assemblies 80 also comprises a plurality of propellant cup members 85, and they also comprise the afterbody 86 with tapered edge 87, and this tapered edge extends back from the transverse wall 88 that is similar to main body 81, as shown in figure 16.When they being assembled in together in the gun barrel (not shown) and axial loading in gun barrel the time, the wedging action on the tapered skirt portion makes each afterbody seal barrel bore effectively, described in the applicant's previous international application.
With reference to Figure 17, as can be seen, projectile body of being assembled 81 and cooperation cup shell 85.1,85.2 have formed a hole effectively, and this hole is separated by the wall 88 formed wall elements of walking crosswise by propellant cup members.Therefore, offer the initiator that advances ammunition 89 to be provided with together along with each by transmitting of will encoding, thus can launch simultaneously one, two or three all ammunitions obtain desirable projectile initial velocity.
Another embodiment of the present invention is at Figure 18, shown in 19 and 20, wherein projectile body 91 comprises band or the ring 94 on head 92 with the central spine that extends back and the head that is arranged on projectile body 91, and wherein ring and head comprise complementary taper surface 95,96.Auxiliary projectile body 97 also comprises the ring 99 of central spine 98 and like configurations.In both cases, ring is arranged to provide effective sealing to the thorax hole of gun barrel (not shown).
With reference to Figure 20, it should be understood that independent propelling ammunition 101,102,103,104,105 and 106 can selectively light simultaneously by having transmitted of receiving that initiator 111,112,113,114,115 and 116 separately provided is excellent by special.In an embodiment of the present invention, each initiator and receiving-member one, this receiving-member can directly receive from the transmitting of signal transmitting coil set on the gun barrel (not shown), and so just need not second receiving coil.
In addition, it is how to be applied in the projectile assemblies together that this embodiment also shows different propelling ammunition separating components, because given a pair of ammunition 103-104 is via auxiliary projectile 97.1,97.2 walk crosswise wall and 101-102 separated with 105-106 with other ammunition, each internal ammunition of described ammunition can be via nonmetal bag 121,122,123 simultaneously, 124,125 with each shells of 126 forms and separate.
In the above-described embodiment, it being understood that before emission remains on any propelling ammunition in the gun barrel, next emission bullet emission in the projectile heap after the particular projectile and can remove from gun barrel by independent the initiation.
And what can expect is that propellant of the present invention is separated and selectively caused and dispose in many other the previous projectiles designs and barrel assemblies structure that can be used for the applicant.More briefly, but NM here existing design and structure can adopt the SCB method (or other initiating method) of the less propellant loads of independence of above-outlined and coding obtain the projectile of the variable range of electronic selection.
For example in the side view of the barrel assemblies 70 of Figure 13, projectile 71 axially is stacked in the gun barrel 72, advances ammunition 73 can be divided into four load 73.1,73.2,73.3,73.4, each load is contained in and contains initiator 74,75 separately, in 76,77 the bag, as shown in figure 14.
Be added with the SCB of different coding outward by each bag, every emission bullet adds induction coil to (not shown), and we have obtained and similar system above.Notice that the present invention can be applicable to other structure (clearly not mentioning) of projectile and barrel assemblies here, including but not necessarily limited to those inventions of the applicant, but these other structures must drop in the scope of the present patent application.
It should be understood that the foregoing description is only provided by example of the present invention, those skilled in the art are clear that other modification and improve and should drop in the above-mentioned broad range of the present invention and boundary.
