A projectile containing multiple propellant: charges that are able to be individually selected for ignition. Each charge has a selectable initiator that may be triggered by a wired or wireless firing system, preferably an inductive system, in order to determine the kinetic energy of the projectile. The projectiles are typically stacked for firing from the barrel of a weapon. Exit ports for ignition gases may be located in the tail portion of the projectile for propulsion of the respective projectile from the weapon, or in the nose portion of the projectile for propulsion of a leading projectile from the weapon. The charges may be distributed around a longitudinal axis of the body or distributed along the axis.

Description

200526917 (ii) Description of the invention: [Technical Field of the Ming] Field of the Invention The present invention relates to a 5-projectile having a variable energy selected when the projectile is launched. In particular, although not limiting, the invention relates to the selective ignition of one or more of a plurality of propellant doses associated with a &quot; usually a mortar-type projectile, and such propellant charges The quantities are axially stacked in the barrel to fire sequentially. L · il ^ r] |! 〇 BACKGROUND OF THE INVENTION It is possible to change the kinetic energy of conventional projectiles, such as standard mortars, by using a customized amount of propellant associated with each projectile before launch. This will, if possible, require different internal propellant loadings during the manufacture or use of auxiliary propellant doses. In 15 &amp; shells, the projectile and auxiliary propellant charge are usually separated from each other before launch. Supplementary propellants are usually provided in several small kits that can be supplied from different volumes or the same volume for incremental use. Depending on the required range, the 'mortar operator manually attaches one or more pill packs' to provide an appropriate amount of propellant to the mortar shell before it is inserted into the tube or barrel for launch. This procedure also significantly slowed the rate at which the weapon could be fired and was prone to human error during loading. Please understand the need for a more cost-effective, convenient, and reliable configuration for changing the kinetic energy of a projectile, especially when high launch rates are required. This is especially true when the projectile-launching weapon is a type that includes multiple rounds that are stacked in a barrel for sequential firing. It would be more advantageous if the structures of the individual rounds were roughly homogeneous.

I: Embodiment 3 Description of the preferred embodiment As can be understood with reference to the drawings, the present invention can be implemented in a variety of ways for a variety of projectiles and purposes 200526917. The present invention can be provided, for example, as a single projectile, as a projectile containing a weapon, or as a barrel assembly including a stacked projectile, for insertion into a weapon. The embodiments described herein relate to mortars with a maximum caliber of approximately 60 mm. Please understand that the present invention can be applied to a variety of projectile configurations. In particular, the projectile is configured to be axially stacked in a barrel assembly and configured to be sequentially fired by an electronic device, as derived from one or two earlier patent applications by these inventors Expose. Fig. 1A shows a projectile 10 having a body 10 including a nose and a tail 11 and 12, which can be stacked in a barrel with other similar projectiles. The projectile usually includes a payload 13 which may belong to various types such as explosives, flash-bangs, smoke or flame retardants. The propellant charge 14 is contained in a cavity in the projectile body and is selectively ignited by a respective initiator 15 preferably a sensing element such as a semiconductor bridge (SCB s), but a 15 series wire can be used Control or wireless detonator system. For example, the dose can be held in its cavity by a plug 16 which may have a thread or by gluing in place. The port 17 is provided in the nose to leave the gas produced by the combustion of the medicine amount. In this example, the port opens forward and advances a leading adjacent projectile from the barrel. This projectile is propelled by a trailing amount of medicine in the adjacent projectile or by the amount of medicine in the base of the barrel. The nose is preferably shaped to fit the tail of the front missile projectile, and the tail is also shaped to fit the nose of the trailing projectile. This provides a certain degree of sealing between the projectiles and can be achieved in a number of ways. Figures 1B and 1C are end views of the projectile of Figure 1, showing the nose and tail. There are four propellant drugs 200526917 with a volume of 14 symmetrically arranged around the longitudinal axis of the projectile, and with four plugs 1 (5 丄, 气体 17 which the combustion gas leaves.) The stomach is held and correspondingly provided. Four can be used for specific projectiles. However, the number of miles and the configuration may be changed to match the projectile before it is launched from the barrel, unless all the charges are in the flight characteristics of the projectile. ^, ' When the dose is selected and ignited, the 1D diagram of the projectile shows that the center of mass of the projectile may shift, for example. Medium. The nasal sound of the trailing projectile; two of this type of projectile are stacked in a barrel and are relatively small. It is better to extend the tail portion 12 into a two-port missile tail portion 12, for example, the nose of the nose is convex on the inside of Jing-sealed contact portion. This range is also a surface, and the tail portion also includes a flexible table. , Matches a concave table 18 in the tail. Among the trailing projectiles, the body of the projectile is in contact with the outer edge. <Multiple doses can be selected and ignited by the kinetic energy of = the projectile has been pushed from the barrel. Any remaining, extreme, etc. 5 The charges in the early hair tunnel projectiles are all ignited. The trailing projectiles of the missile projectiles generate a fixed weight of 15 and 15 lbs .- ^ Each projectile has a standard and conjectured flyaway 1e &amp; if diagram. Shows how this type can be fired-the last projectile in the stack. The propellant charge 14 may be provided in the base of the barrel to become a -removable removable element 19E, or to become a barrel-like element. The drug amount 14 in each figure is contained and ignited in a manner similar to the drug amount in the projectile. The separated base element 19E is preferably loaded down the barrel before the projectile, and the amount of medicine in the fixed element 19F can be loaded to be an individual object behind the barrel. These doses can be redirected and fired to provide a predetermined kinetic energy for the final projectile. 20 200526917 10 15 Figure 2A shows an alternative projectile with a body 20 including nose and tail portions 21 and 22, which can be stacked in a barrel with other similar projectiles as needed. In this example, the projectile includes a payload 23. The propellant charge 24 is contained in a cavity in the projectile body and is selectively ignited by a respective initiator 25, preferably a sensing element such as a semiconductor bridge (SCBs), but a series of wire-controlled or wireless Detonator system. For example, the dose can be held in its jealous cavity by a plug 26, which may have threads, or by gluing in place. The port 27 is provided in the nose so that the gas generated by the combustion of the medicine amount is separated. In this example, the port opens back and advances the respective projectiles from the barrel. The nose is preferably shaped to fit the tail of the front missile projectile, and the tail is also shaped to fit the nose of the trailing projectile. This provides a certain degree of sealing between the projectiles and can be achieved in a number of ways. Figures 2B and 2C are end views of the projectile of Figure 2A, showing the nose and tail. There are four propellant doses 24 ′ arranged symmetrically around the longitudinal axis of the projectile and held by four plugs 26 and correspondingly provided four = 璋, gas leaving 璋 27. The quantity and configuration of the dose may be changed to match: The purpose of the specific projectile. Please understand that the flight characteristics of the bomb can be changed when the dose is selected and fired. The weight and center of mass of the projectile may change, for example. _ On the other hand, future exit ports are less likely to generate resistance. The 2D picture in the text shows how two of this type of projectiles cannot be stacked in the middle of the tail of the carcass. The nose 21 is matched with the tail of the front missile projectile. ^ It is better to extend the tail 22 in the barrel __ dense The convex curved surface of the 'nose' in the esoteric touch matches the 'concave' in the tail: and the tail also includes-it can make contact with the body of the trailing projectile 20 200526917 28. Please understand that a wide variety of shapes and sizes can be used in any of the projectiles described here. One or more doses in each projectile can be selected and ignited to use the required kinetic energy to advance each projectile from the barrel. Projectiles generally have more unpredictable flight characteristics than Figure 1A. 5 Figure 3A shows in more detail a typical propellant dose of 14 or 24 in Figures 1 and 2. The dosing material 300 is contained by a metal casing 300, which is fully opened at one end 302 and has a smaller opening 300 at the other end 304. A disc 305 made of composite material blocks the openings 303 but will break when the dosing material is ignited to allow combustion gases to pass through the openings into a respective outlet port. 10 An initiator 306 fits into terminal 30 by threading or press-fitting, and is based on an SCB igniter in this example. The initiator includes a SCB 307 connected across a coil of 308, and both are mounted in a plastic accessory, such as 309. A small amount of pyrotechnic material 31o surrounds the SCB as a drug supercharger. Fifteen alternative structures can be used for the propellant dose and the initiator, and they can be introduced directly into the cavity in the projectile, for example, without the housing 301. Semiconductor bridges such as those shown in U.S. Patent No. 4,708,060 and subsequent U.S. patents are known devices having a microchip appearance that includes two termination lines. If a potential is placed across these two lines, the semiconductor bridge releases most of the energy as a small amount of heat. In some cases, the energy released by SCB may not be sufficient to directly ignite the propellant dose, and the initiator may further require a chemical compound (that is, a kind that can be triggered by a SCB and thereby charge the dose Ignition compounds). The SCB can be designed and configured so that the current induced between the two terminals will cause energy release. As those who are familiar with this technology 12 200526917 10 15 20 are already familiar with different kinds of hands using the electric field, "the (induction) in-wire coil t induction caused injustice / melon / again, so it is not described here These details are not necessary to provide examples. Therefore, 'all such providing appropriate emission current :: current or other means' are within the scope of the present invention. ⑷ Figure 3B shows schematically-can be used to shoot The inductive launch system of the projectile shown in the figure can be used. A buckle Mr. A can be used instead of a signal transmitting coil 33 wrapped around the barrel 30 and suitable for being located near the projectile 31, that is, for each projectile _ 2 etc. "Da or the main coil 33. Bu 33.2 etc., by which the magnetic field suitable for starting the SCB can be induced. The emission control unit can be used to selectively switch on or off the current in the main coil 33, so it can be done in the same way. Manipulate the current generated in the receiving or secondary coil 35. The FCU can be operated in different ways to select the kinetic energy, so the dose is ignited for the next projectile launch.-The user of the health can operate one Simple The ground refers to a rotatable switch that is not 1, 2, 3 ... or all the doses to be ignited. The user or an automatic launch system determines the required projectile for a particular projectile according to the environment in which the user or automated system is located In order to launch a charge in a designated projectile (such as projectile 31.2), the FCU 39 applies a firing signal current to the main coil 33.2 wrapped around the barrel 30 for the projectile 35.2. The generated magnetic field induces a current in the secondary coil 35.2 and applies it to the two terminals of the initiators 32, 33, 34. In response to these arrangements, it is possible to ignite when the transmitted signal is received.

While firing one or more propellant doses 36a, 36b, 36c. SCB can also be designed so that it will not be triggered by a simple current, and only when a specific "type" occurs. In fact, SCB technology is now available. The ignition signal energy to activate the SCB capability of energy materials. As needed, ^ -ρ can also be used in conjunction with the SCB technology, encoders and decoders. If a device / solution and other circuits, the modulation scheme can include any Pulse _ side), pulse code _ (pcM) or pulse amplitude modulation (PAM) scheme, or cup beat sweet / u &amp; any other appropriate coding scheme. This can be marinated by common induction coil pairs 33, 35 Eight secret ^ ^ wood will ignite discretely, the smaller propellant dose 36 discretely. At this time, people consider, for example, using a change in current to embed an ignition signal in order to 'fix (or any special) projectile. 2 After firing the propellant 10 amount 36a, the FCU 39 applies a current (with a suitably modulated change embedded in it) to the main coil 33.2 connected to the projectile. The motor (generated by the magnetic field) generated in the secondary coil 35.2 (Induced) so the needle ⑶ has The change in the applied current produces a proportional change in intensity. Therefore, the current induced to the plutonium also changes in proportion to the change in the magnetic field strength. Therefore, it is possible to adjust the propellant load of 15 projectiles 35.2 to 36 minutes. Moderately difficult 32 delivers appropriately coded signals, and therefore can be triggered using a single induction coil 33 in each projectile without initiating a propellant charge 36b or 36c. Please understand that one or more selected propellant charges When 36 is triggered, its rapid combustion will have the effect of ejecting the associated propellant from the barrel 30. If only 20 propellant doses are triggered, for example, by SCB 33, the central dose 36b will be transmitted to the projectile. The kinetic energy will be significantly lower than the kinetic energy delivered when all three propellant doses 36a, 36b, 36c are triggered. Figures 4 to 8 depict a projectile 45 according to another embodiment of the present invention, which has a The projectile body portion 46 of the cavity 49, wherein a plurality of propellants 200526917 with a dose of 50 are longitudinally arranged in the projectile. On the contrary, the propellant dose of the above embodiment is disposed laterally in the projectile. For the sake of clarity For the sake of illustration, the initiator and the secondary or receiving coils have been omitted in these figures. Figure 4 depicts the fringe projectile 45, which is in a state before any propellant dose 50 is ignited 5 in the cavity 49 The wall is separated from each other by a wall member. The propellant charge 50 is made of a moldable material in this embodiment, thereby opening through the opening of the conductive body adjacent to a tail portion of the body portion 46. The final dose of 50.4 is exposed. The wall member is suitable in the form of a sealing disc 51 having an edge surface. 'The contours of the edge surfaces are arranged to wedge into a shallow push-in wall of the cavity ^ 10. Thus, the shaped propellant dose and the alternating sealing disc can be positioned in the cavity 49 from the tail portion 48 of the projectile 45 through the opening 58. Because the propellant cavity becomes smaller in the direction of the projectile head 47, if the first loaded zoom disc 51 is forced to face the projectile head, 15 wedging will occur at the edge of the band and the cavity. 47 between the push-like inner walls, and the dish holds the foremost dose 50.1 in position. For this reason, when a launch-like force is applied during the launch (such as the second propellant dose issued by the bow) 50.2 force caused by combustion), the sealing disc 51 will be further wedged into position with the internal wall 56. This "wedge seal," the purpose is to reduce the propellant charge by 20 doses of 50 2 ignition caused by ignition A quantity of 50 · 1 creates any possibility of sympathetic or "blow-by" ignition. However, the ignition of a propellant volume of 5 (U will push the adjacent seal band portion in other directions. It can be unlocked and forced towards the tail 48 of the projectile 45. The cooperation between the edge of the rhyme disc and the cymbal wall will be lost 15 200526917 5 10 before touching, the sealing disc 51 will not move to a distance, 1 let incineration The pusher agent 50.1 reached the rear propellant drug magnitude 2. So ^ will The next rear propellant dose of 50_2 will ignite and continue this process quickly, until the propellant volume of 50.4 is ignited. In summary, as mentioned above, one, ^ ^ special propellant dose of 50 igniters * will Ignite the propellant dose near the nose of the projectile. Figures 5, 6 and 7 show the projectile 45—selected push_ = fire sequence. In Figure 5, the third propellant dose 5G3 has been Ignition, resulting in the combustion of the doses 50.3 and 50.4. In the sixth figure, the first pumping ', the first brother's propellant dose 50.2 has been ignited', causing the combustion of the doses 50.2, 50.3 and 50.4. Figure 7 In the first propellant dose of 5 (U has been ignited, resulting in the burning of all propellant doses. The opening includes a device for resisting the sealing plate from advancing from the cavity, which presents a number of fingers or cards that extend radially inward. The form of stop 57 is shown in Figures 4 to 8.

15) to prevent or at least resist the sealing disc 51 from being completely driven out or otherwise leaving the projectile cavity 49. There are several small locking points 57 with matching openings and edges, as shown in FIG. 8. — A better alternative includes extending the locking point across the opening in the form of a crossbar to secure the disc in the projectile 20. In another form, the wall member of the sealing disc may be composed of a combustible material, and the rectification material has an outer surface which is treated to resist combustion, that is, it can only be consumed by burning the propellant in front of the wall member. The mouth is OK. A or I may or may not be able to conveniently make the ejection body. The knife I cavity 49 is already loaded with a propellant dose of 50 and a separate sealed dish. The ejection point 5 7 will be formed. For example, by the cooperation of the screw thread (not shown in Fig. W is detachably held in the tail of the separated components%. Figure 9 shows a modification of this component of the fourth embodiment.

16 200526917 In another modification, the integral cavity portion 49 including the rearward opening 58 can be formed as a separate component and is also removably retained in the projectile body portion 46. As mentioned above, the separate components containing the cavities may be formed with a propellant charge and a lateral arrangement of the respective extended sub-ports. 5 In the fifth embodiment of the present invention shown in Figs. 10 and 12 (the initiator and the secondary or receiving coil are omitted again), a projectile 60 series includes its own via the edge of the wall member and the propellant cavity. 63 cooperating threads 62 on the inner wall and threaded screwing to the wall member 61 in position. And, as shown in FIG. 10, each of the wall members 61 includes a sealing plug 64 that is wedged into a position of the wall member 10 in a manner similar to the above-mentioned sealing disc. The sealing plug 64 is provided with a shaped retaining member 65 for preventing or at least resisting the plug from completely leaving the projectile cavity 63. At present, it is expected that the seal 2 plug 64 will be made into two pieces (that is, the plug and the retaining member) and assembled on site. In a manner similar to that of the fourth embodiment described above, the T-shaped portion is composed of a plurality of small stop points instead of using the entire ring. However, in this embodiment, the locking point is a plurality of fingers 66 having a slightly cross-shaped # extending outward. As described above, when a T-shaped member 65 collides with its respective wall member ㈠, the propellant dose 67 will not appear closed to the outside of the projectile 60, as shown in the nth cross section. Shuangda 20 ‘Front considers that, for the screw-in wall 61 closest to the rear of the projectile, b 0 Shi Li main camera frontmost Γ holding member 65. Figure 12 shows the end result of igniting only the M dose 671 in this scenario. Each projectile may use an induction coil to ignite an individual propellant dose 67 (as described in Figure 3A and 1B), where for each propellant dose 17 200526917 67.2, 67.3, etc. After different obstructions. For this — in the example of the fifth embodiment, four kinds of _same_ ^ are currently required to display SCBs.

Figures 15 and 16 show the applicant's international PCT / A deletion _ shan shi _ _ _ _ _ Cheng: The case of the early invention is related to a plurality of pushers 结 与 with each projectile _ ΐ: Τ :: The muzzle velocity of the projectile of Γ. j

-The applicant has now understood that the present invention may have further applications as described in this sixth 15th embodiment. Here, each projectile assembly ⑽ includes a main projectile body 81, which has a head 82 and a tail 83 extending rearwardly including a push-type skirt 84, as in the 15th As shown. The projectile assembly 80 also includes a plurality of propellant cup members 85 that also include a tail 86. The tail 86 has a push-like skirt 87 extending 20 back from a transverse wall 88 similar to the main body 81, as shown in FIG. 16 As shown. When assembled together in a barrel (not shown) and subjected to an axial barrel load, the wedging action on the push-shaped skirt effectively seals the respective tail against the bore of the barrel, as applied As described in Human's Early International Application. Referring to Fig. 17, it can be seen that the assembled main projectile 81 and the cooperative 18 200526917 cup members 85 · 1, 85 · 2 are essentially wall members formed by the transverse 璧 88 of the pushed cup of y. The divided cavity. Therefore, by providing a coded launch signal to the initiator 90 configured with a respective propellant charge 89, it is possible to simultaneously launch-, two or three doses to achieve the required muzzle velocity. 5 帛 18, 19 and 2G show another embodiment of the present invention, in which the main projectile body 91 belongs to a head including a central spine extending backward 92 and a head disposed on the projectile body 91 The type of the belt part or the collar correction on the part%, wherein the collar and the head include complementary push-like surfaces 95, 96. 〆 The auxiliary projectile body ㈣ also includes-the central spine 98 and-the collar member 99 with a _ · 10 state. In both cases, the collar members are arranged to provide an operational seal against the bore of the barrel (not shown). With particular reference to FIG. 20, it can be understood that the individual propellant doses 101, 102, and 101 can be selectively simultaneously received by receiving emission signals from the respective initiators 1 u, 112, 113, 114, 115, and 116. 103, 104, 105 and 106 ignited. In the present embodiment, since each initiator is integrated with a receiving device, it can directly receive a transmitting signal from a signal transmitting coil disposed in a barrel (not shown), so a secondary receiving coil is not required. Φ And the 'example shows how different propellant dose separation devices can be used together in a projectile assembly, where a given pair of doses 103-1 〇 20 is via auxiliary projectiles 97.1, 97.2 Separated from the other pairs 101-102 and 105-106, and the individual doses within the pair can be separated by separate enclosures in the form of non-metal bags 121, 122, 123, 124, 125, and 126 . In the above embodiment, it can be known that after a specific projectile is launched, it can be cleared from the barrel by separating the trigger before the next bow single projectile in the projectile stack is fired. Dosage. Moreover, it is envisioned that the propellant split and selective initiation configuration of the present invention may be used in many other earlier projectile design and barrel 5 assembly configurations of the applicant. In simple terms, there is an existing design and configuration of the above method that utilizes separate smaller propellant loads and coded scB to achieve an electrically selectable range-changeable projectile, not mentioned here. For example, in the tube assembly 70 of FIG. 13, the projectiles 71 are axially stacked in a tube portion, as shown in the cross-sectional side view, and each of them can be used with a separate guide 74, 75, 76. The 77 and 77 bags divide the propellant charge 73 into four loads 73.1, 73.2, 73.3, and 73 4, as shown in FIG. 14. By adding different coded SCBs to each bag and one induction coil pair (not shown) for each projectile, we have a system similar to that described above. By way of example, the present invention may be applied to alternative configurations of projectiles and barrel assemblies (not explicitly mentioned here 15). These alternative configurations include but are not necessarily limited to This application configuration is within the scope of this patent application. Please understand that the above embodiments are provided only by exemplifying the present invention, and those skilled in the relevant art understand that further modifications and improvements are deemed to fall within the broad scope and spirit of the above 20 inventions.
