Uppfinnare: D L Coarsen Prioritet begard fran den 18 mars 1958 (USA) FOreliggande uppf inning avser springamnesskivor, dar en detonationsfront, soma alstras vid en punkt, bringas: att ankomma samtidigt till ett flertal punkter pa en Onskad rat eller krokt Nar en springinmesmassa initieras vid en punkt, fortskrider den bildade detonationsvagen utat frau punkten med lika hastighet i al-la riktningar. Osu exempelvis en tunn platt eirkular sprangamnesladdning initieras vid centrum, fortskrider detonationsfronten genom laddningen i form air en .expanderande cirkel och kommer samtidigt fram till alla punkter p. laddningens omkrets. Nar den Wilma platta laddningen har ratlinjiga granser, har detonationsfronten forst formen av en expanderande cirkel tills den kommer till den del av granslinjen, sorn ar narmast initieringspunkten, .och darefter gar fronten genom resten av laddningen som em expanderande cirkelbage, -Vars. kraningsradie Yid en given punkt i laddningen bestammes av avstdi' idet mellan varje slutpunkt och initieringspunkten. Det ar ocksa. klart, att detonalionsfronten inte kan komma samtidigt fram till ett antal punkter pa en krokt linje, som. icke sammanfaller sued detonationsfrontens naturliga krokning. Inventor: DL Coarsen Priority requested from March 18, 1958 (USA) The present invention relates to spring ammunition disks, in which a detonation front, generated at a point, is brought: to arrive simultaneously at a plurality of points on an unwanted rod or hook. one point, the formed detonation wave proceeds outward from the point at equal velocity in all directions. If, for example, a thin flat circular ballast charge is initiated at the center, the detonation front proceeds through the charge in the form of an expanding circle and simultaneously reaches all points on the circumference of the charge. When the Wilma flat charge has straight lines, the detonation front first has the shape of an expanding circle until it reaches the part of the boundary line which is closest to the point of initiation, and then the front passes through the rest of the charge as an expanding circular bag. crane radius Yid a given point in the charge is determined by the distance between each end point and the initiation point. It's too. clear, that the detonation front cannot simultaneously reach a number of points on a curved line, which. does not coincide with the natural hook of the detonation front.

I manga industriella .anvandningar av sprangamnen, andra an sprangningar, kan man erhalla forbattrade resultat, nar laddningen initieras .samtidigt vicl ett flertal punk-ter ph dess yta. Nar exempelvis en shdan tin-jar eller kilformad laddning som beskrives i den amerikanska patentskriften 2 605 704 for slitsning av par och liknande, initieras vid ett flertal punkter pa en rat linje over dess yta Stallet Thr vid en punkt, erhalles en okad penetrationsjamnhet. Vid det forfarande for forening air inetallelement rued hj alp air sprangamnen, som beskrives i den amerikanska patentskriften 2 367 206, kan en lokaliserad ii-tiering av sprangarrmesladdningen, som omger metallhylsan i redskapet, bland resultera i skada ph fogen, medan ingen sadan skada upptrader om den hylsliknande laddningen initieras vid ett flertal punkter runt laddningens ena aside. In many industrial applications of the explosives, other than explosions, improved results can be obtained when the charge is initiated simultaneously at a plurality of points on its surface. For example, when a tin or wedge-shaped charge described in U.S. Pat. No. 2,605,704 for slitting pairs and the like is initiated at a plurality of points on a straight line above its surface Stallet Thr at a point, an increased penetration uniformity is obtained. In the procedure for joining air metal elements rued by the alp air springs described in U.S. Pat. No. 2,367,206, a localized ignition of the spring arm charge surrounding the metal sleeve of the tool may result in damage to the joint, while no such damage occurs. if the sleeve-like charge is initiated at a plurality of points around one side of the charge.

Anyandningen av en serie individuella: iniiiatorer, sasom sprangkapslar, for att hstadkomana samtidig initiering vid ett antal punk-ter pa en rat eller krokt linje är inte alltid garlig, darfor att de individuella initiatorernag excentriciteter, ehuru de aro tillrackligt sma for att i allmanhet kunna ignoreras, utesluta sin verkligt samtidig initierirtg. Vidare ar den mekaniska uppsattningen av ett stort antal initiatorer intill ytan av det sprangamne, som skall initieras, ytterst besvarlig eller rentav omajlig av utrymmesskal. Den individuella initiatornsi splittringsverkan utesluter ocksa anvandningen av ett stort iantal av dem tatt intill varandra. Sprangaumesskivornas majligheter fOr sadana anvandningar inses darfor utan vidare. The use of a series of individual: initiators, such as bouncing capsules, to allow simultaneous initiation at a number of points on a straight or curved line is not always feasible, because the individual initiators have eccentricities, although they are small enough to generally ignored, exclude its truly simultaneous initiierirtg. Furthermore, the mechanical arrangement of a large number of initiators adjacent to the surface of the gap material to be initiated is extremely responsive or even impossible for space shells. The fragmentation effect of the individual initiator also precludes the use of a large number of them taken side by side. The possibilities of the spring rubber discs for such uses are therefore readily understood.

En linjevhggenerator har fOreslagits, vilken innefattar en bojlig slang, innehallande ett antal inerta fasta distansorgan, som bilda ett natverk av mellanrum, van i ett sprangamne är anbragt. Derma anordning, sorn beskrives i den amerikanska patentskriften 2 774 306, ger tillfredsstallande initiering for manga syften, men lider air att den ar komplicerat uppbyggd, sa att det atom antalet komponenter i .anord- Dupl. kl. 78 e: 2 ningen leder till en komplicerad tillverkningsprocess. A line wall generator has been proposed, which comprises a flexible hose, containing a number of inert fixed spacers, which form a network of gaps used in a gap blank. This device, as described in U.S. Pat. No. 2,774,306, provides satisfactory initiation for many purposes, but suffers from being complicated in construction, so that the atomic number of components in the device is doubled. at 78 e: 2 ning leads to a complicated manufacturing process.

Foreliggande uppfinning tillhandahaller en sprangamnes.skiva, som ãr enkel till konstruktion och effektiv i bruk. The present invention provides a springboard which is simple in construction and efficient in use.

Sprangamnesskivan enligt uppfinningen be-star av en skiva av snabbdetonerande explosivamne, vilken är s utformad med Oppningar, att de kortaste banorna fran initieringspunkten till varje slutpunkt pa den onskade detonationsfrontlinjen langs de av oppningarna begransade sprangamnesbanorna aro lika varj &lute skive:us tjoeklek iir sadan och oppningarna ha sadana dimensioner och inbordes avstand, att detonationen kan fortplantas endast langs sprangamnesbanorna. The explosive disk according to the invention consists of a disk of fast-detonating explosive substance, which is designed with openings, so that the shortest paths from the initiation point to each end point of the desired detonation front line along the explosive path bounded by the openings are equal to each disk and the thickness of the disk. the openings have such dimensions and inboard distance that the detonation can propagate only along the burst amnesty paths.

Nar initieringspunkten och den rata granslinjens andar bestamma en liksidig triangel, kunna oppningarna vara eirkulara med enhetlig storlek och vara fordelade i ett reguljart hexagonalt arrangemang, sa att de bilda sidoforskjutna rader parallella med angelns bas..

The openings may consist of a plurality of parallel-sided slits, which are parallel to each other and to one of the sides of the triangle, the spirits of the slits being on limes, one of which coincides with, or is preferably parallel to, the base and the other lies between the base and the third of the triangle. side and is parallel to the triangle. third page. When the point of initiation and the spirits of the straight boundary line define an equilateral triangle, the apertures may be circular in uniform size and be distributed in a regular hexagonal arrangement, so that they form laterally offset rows parallel to the base of the angle. Circular apertures may also be arranged at intersection points in a polar coordinate, the origin of which is at a point on the line passing through the tip of the triangle and the center of the base.

In the case of a polar coordinate night, however, the springboard with circular apertures centered at a polar coordinate preferably has the shape of a tip-back triangle, the apex of which is the point of initiation and whose axis is the end points containing the straight boundary line.

In addition to springboard disks, in which a detonation front simultaneously reaches a plurality of end points on a straight boundary line at the springboard, it is possible, by appropriate choice of the shape, size and arrangement of the openings, to produce a springboard, which at the endpoints form a hook line. ex. an eirkel, or several straight or crooked e.g. lines, which form a polygon.

(For varje spranganme med, given tvarsnittsarea finns; det ,ett bestarnt minimiluftgap, over vilket en detonationsvag inte kan fortplantas). Salunda inses det latt, att detonationsvagen kan tvingas att folj a en forutbestamd och onskad bana. Nar luftgapen, oberoende ay deras form, ha tillracklig dimension fOr att styra avbojningen av detonationsvagen och aro sa fordelade, att den kortaste detonationsvagen mellan utgangspunkten och nagon slutpunkt Or lika med den kortaste detonationsvagen Indian initieringspunkten och varje annan slutpunkt, kommer detonationsvagen samtidigt fram till alla slutpunkterna 3 oberoende av den exakta formen av de banar, som vagen har tagit. More specifically, visor Figure 1 shows a skim of a fast-detonating fissure blank with a completely irregular shape and provided with numerous irregularly shaped openings randomly distributed over the disc. The fissure forms a continuous mass. When the charge is initiated at the point Po, the initiation point, the detonation proceeds outwards at a given speed along different detonation paths R, which are indicated by the dotted lines in the figure from the initialization point Po to the end points P1, P23 P3. • • • Pp., Which form the line L on the periphery of the charge. The detonation waves R taken by the detonation wave are determined by the shape and size of the random iris openings and have in all cases a cross-sectional area, Wo, which is equal to or greater than the minimum required to prevent the detonation from dying out. [For each range, there is a certain minimum dimension, (width or thickness), most suitable wages as cross-sectional area, which requirement for maintaining on detonations and detonation has been found gd in the middle between the edges of this minimum area, the sasor is shown by the dotted lines in the figure. As can be seen from Figure 1, the detonation carriage moves along various detonation carriages with a sufficient cross-sectional area to maintain the detonation, the carriage passing over or past air gaps alit as they are below or below the minimum size which prevents the detonation from propagating. (For each burst with a given cross-sectional area there is; there is a fixed minimum air gap, over which a detonation wave cannot be propagated). Thus, it is readily appreciated that the detonation wave may be forced to follow a predetermined and desired path. When the air gaps, regardless of their shape, have sufficient dimension to control the deflection of the detonation wave and are so distributed that the shortest detonation wave between the starting point and any end point is equal to the shortest detonation wave Indian initiation point and any other end point, the detonation wave reaches all the end points 3 regardless of the exact shape of the paths taken by the carriage.

Figure 2A shows a burst ammunition disk where the detonation front generated at point P0 advances along. detonation paths R and simultaneously reach a series of points P1 — P8 ph a rat Buie. The side of the spring is in the form of an isosceles triangle and is perforated with a number of parallel sides, slots, which are parallel to each other and with one side of the triangle and whose spirits are on lines, one of which is parallel to the axis of the triangle and the other Or parallel to the third side of the triangle.

The device, according to Figure 2D, is also of triangular shape and also produces a helical vaginal front, in that the detonation front simultaneously arrives at end points P1-11'10, which are covered by a helical line. In this case, the triangular fissure shape is formed with races of tightly fitted 1T-shaped openings, which are parallel to the triangular side containing the end points, and arranged so as to form straight columns of the openings.

Figure 2F shows a bursting disk, where a detonation front generated at a single initiation point Po is caused to land simultaneously at a plurality of points, forming a circle. In this embodiment, the spring material was in the form of a ring around a circular hall, the points of the lungs being the inner edge of the ring. The end points, some of which are denoted by P1-P8.

I figur 2G visas en utforingsform, dar den vid en enda initieringspunkt P0 alstrade detonationsfronten anla.nder samtidigt till ett antal punkter, som bilda en rektangel, varvid spranganmesskivans ytterkanter begransa en polyeder och innerkanterna en. rektartgel.

Figures 3a, 3b, 3c and 3d are images showing the travel of the detonation wave through the ammunition disk of Figure 2B, taken 7.25, 15.5, 21.2 and 31.7 microseconds, respectively, after initialization.

Sasom framgar am del foregiende, kan den onskade omforrnningen av detonationsfronten latt uppnis ph ett ,antal olika sat ,utan att tillverkningen kompliceras Over hovart. De kritiska sardrag, som kravas, for oinformningen, One (1) att sprangannnet maste ha forraen av en sammanhangande massa, (2) att oppningarna mhste ha tillrackliga dimensioner for att hindra fortplantning am detonationsvagen tvars Over oppningen, och ,(3) att den kortaste detonationsvagen (dvs. den kortaste vagen med tillracklig tvarsnittsarea for att underhalla detonationen) fran initieringspunkten till en av slutpunkterna maste vara vasentligen lika med den kortaste detonationsvagen a frau. initieringspunkten till Var och en av de andra slutpunkterna.. Pa grundval av dessa uppgifter kunna nanga former av spranga_mnesskiva, forutona de ovan beskrivna, fram.sfallas for att producera linjara detonationsfronter v olika geometriska ' former. Dess'dont k-unna ett antal sadana vaggeneratorer 8ammanstallas, t. ex staplas, for att alstra en tvadimensionell, t. ex. plan, detonationsfront. As can be seen from the foregoing, the desired remodeling of the detonation front can be easily specified in a number of different ways, without complicating the manufacturing process. The critical features required for the information, One (1) that the gap must have the front of a continuous mass, (2) that the openings must have sufficient dimensions to prevent propagation of the detonation carriage across the opening, and, (3) that the the shortest detonation wave (ie the shortest wave with sufficient cross-sectional area to maintain the detonation) from the point of initiation to one of the end points must be substantially equal to the shortest detonation wave a frau. The initiation point to Each of the other endpoints .. On the basis of these data, some shapes of burst_mness disk, in addition to those described above, can emerge to produce linear detonation fronts in different geometric 'shapes. It is not necessary to assemble a number of such cradle generators, for example stacked, to produce a two-dimensional, e.g. plan, detonation front.

Den anvanda sprangamneskompositionen är ej kritis.k rami. blott explosivananet detoneras med stor hastighet och kan forums till den nodvandiga sammanhangande skivan. En komposition av ett'sprangkapselkansligt kris- tailintt. ex. PETN, och ett av elastomer och harts bildat hindemedel, t. ex. innehallande 92,5-77,5 % av sprangamnet och med bindemedlet innehallande 25-75 % av elastomeren, kan latt formas till den Onskade ski-van for omvandling till den kontinuerliga massan: samt detonerar i allmanhet med en hastighet av 6000-7000 m/s. Ehuru derma komposition ar det foredragna snabbdetonerande sprangamnet, ligger anvandningen av ,andra snabba skivlika sprangamnen, t. ex. skivor av spranggelatin, mom ramen fOr uppfinningen. The used explosive composition is not kritis.k rami. only the explosive is detonated at high speed and can be forums to the necessary cohesive disc. A composition of a bouncy capsule-sensitive crystalline. ex. PETN, and a barrier agent formed of elastomer and resin, e.g. containing 92.5-77.5% of the blank and with the binder containing 25-75% of the elastomer, can be easily formed into the desired disk for conversion to the continuous mass: and detonates generally at a speed of 6000-7000 m / s. Although this composition is the preferred fast detonating blaster, the use of other fast disc-like springs, e.g. slices of spring gelatin, within the scope of the invention.

,Oppningarnas dimensioner hero naturligtvis pa det specifika snabbdetonerande sprangamne, sour bildar massan, eftersom storleken av det luftgap, som behoys for att hindra fortplantning air detonationsvagen, beror pa. 'spranganmets beskaffenhet. Exempelvis mhste oppningarna i det sprangamne, som anvandes i exemplet nedan, ha en minsta dimension av atmin.stone 0,051 cm for att erbjuda det erforderliga luftgapet. Naturligtvis ãr detta varde annorlunda nar andra sprangaranen, sasom. spranggelatin, .anvandas och saledes ar det exakta minimivardet pa den minsta dimensionen joke ett fixerat varde. Sprangamnesbanornas tvarsnittsarea paverkar ocksa oppningarnas tvarsnittsarea, i det att ju stew-re banornas tvarsnittsarea 5r, desto storre oppning kravs for att forhindra detonationen Over dem. The dimensions of the apertures, of course, depend on the specific fast-detonating explosive, forming the mass, since the size of the air gap needed to prevent propagation of the air detonation path depends on. 'the nature of the leap. For example, the openings in the gap blank used in the example below must have a minimum dimension of at least 0.051 cm to provide the required air gap. Of course, this was different when the other runner, as well. spring gelatin, .used and thus the exact minimum value of the smallest dimension joke is a fixed value. The cross-sectional area of the track ammunition tracks also affects the cross-sectional area of the openings, in that the larger the cross-sectional area of the tracks, the larger the opening required to prevent the detonation above them.

Den_ minimitvarsnittsarea, som kravs fOr att underhalla detonationen, beror ocksâ pa. beskaffenheten av det sprangamne, som bildar skivan.. For det i nedanstaende ,exempel angivna sprangamnet Or derma minimiarea 7,8 mrn2 Eftersom tvarsnittsarean beror pa bred-den av bryggan: mellan oppningarna och sprangamnesskivans tjocklek, kan den minimikvantitet sprangamne, som lu.avs for att underhalla detonationen, ocksa uttryckas med sambandet+= K, dar T Or skivans T tjocklek, Wo Or den minimala bredd pa bryg- gan, sorn Or noclvandig I Or att underhalla detonationen, och K är en konstant. For det erremplifierade sprangaranet- är K 0,72 mm-1. Som ovan angivits med avseende p0. oppningsstorleken, kommer emellertid Oct specifika vardet pa tvarsnittsarean liksom ph konstanten K i tjockleks-breddekvationen, om derma skall tillampas, att variera med det ranvanda sprangamnet, sO att den. exakta minimitvarsnittsarean eller konstanten-inte är ett fixerat varde. The minimum cross-sectional area required to maintain the detonation also depends on. The nature of the gap element which forms the disc. For the gap name given below, for example, the minimum area 7.8 mnr2. Since the cross-sectional area depends on the width of the bridge: between the openings and the thickness of the gap member disk, the minimum quantity of gap substance, which is to maintain the detonation, is also expressed by the relation + = K, where T Or the thickness of the disc T, Wo Or the minimum width of the bridge, sorn Or noclvandig I Or to maintain the detonation, and K is a constant. For the errplified splitter network, K is 0.72 mm-1. As stated above with respect to p0. opening size, however, the specific value of the cross-sectional area as well as the pH constant K in the thickness-width equation, if applied to this, will vary with the usual gap blank, so that it. exact minimum cross-sectional area or constant-is not a fixed value.

I manga fall kan man for -en given konfiguration av sprangamnesskivan stalla upp ett matematiskt uttryck, som anger ett samband mellan ba:nornas erforderliga dimensioner och luftgapet eller oppningsstorleken. Exempelvis erhalles for konfigurationen enligt figur 2B, dvs. en triangular spranganmesskiva fOrsedd rued, ett regulj art hexagonalt mOnster av cirkulara ha], en fullkomligt rat detonations-front, nar 2(lAr W°)= 0,122 2R + Wo dar W Or bredden hos bryggan av sprangamne mellan narliggande hOJ, Wo Or den minimibredd hos bryggan, som underhaller -en -detonation, och R Or oppningens radie. Emellertid kan man .erhalla tillrackligt rata fronter fOr manga syften, nar foljande olikhet är satisfierad: 2(W — 0,00,9 2R +W0 Foljande exempel beskriver en 0.skad1igg5.. rande utforingsform av sprangamnesskivan enligt uppfinningen.

In many cases, for a given configuration of the springboard, a mathematical expression can be set up, which indicates a connection between the required dimensions of the tracks and the air gap or opening size. For example, for the configuration of Figure 2B, i.e. a triangular fissure blade provided, a regular hexagonal pattern of circular ha], a perfectly straight detonation front, when 2 (lAr W °) = 0,122 2R + Wo dar W Or the width of the fissure bridge between adjacent hOJ, Wo Or the minimum width of the bridge, which maintains -en -detonation, and R Or the radius of the opening. However, sufficiently straight fronts can be obtained for many purposes, when the following difference is satisfied: 2 (W - 0,00,9 2R + W0 The following example describes a damaging embodiment of the springboard according to the invention. a flexible sheet produced from a mixed grade 85/15 ratio of PETN and a binder consisting of 50% butyl rubber and 50% of a thermoplastic terpene carbonate resin ("Piceolyte" which is commercially available from Pennsylvania Industrial Chemical Corporation and consists essentially of polymers of the fl-pin).
