Den foreliggende opfindelse angår en ammunitionsenhed, der kan skydes ud med overlydshastighed og er finnestabiliseret, til øvelsesformål beregnet til at erstatte kampammunition med konventionelt ogivalt eller konisk næseparti, og af den art, som ud til en maksimal skudafstand har 5 en ballistik, der hovedsagelig svarer til ballistikken for tilsvarende konven tionel kampammunition, men som har en maksimal skudrækkevidde, der er væsentligt reduceret, f.eks. til det halve, i forhold til den konventionelle kampammunition, omfattende en forreste spidsformet del, en cylinderformet mellemdel og et langstrakt haleparti, hvis længde overstiger mellemdelens 10 og spidsens respektive længder, og er udformet med et antal finner.BACKGROUND OF THE INVENTION The present invention relates to an ammunition unit which can be shot out at a supersonic rate and is finely stabilized, for training purposes intended to replace combat ammunition with conventional ogival or tapered muzzle, and of a type which, up to a maximum firing distance, has a ballistics which is substantially similar. for the ballistics of similar conventional combat ammunition, but which has a maximum firing range that is substantially reduced, e.g. by half, relative to the conventional combat ammunition, comprising an anterior pointed portion, a cylindrical intermediate portion, and an elongate tail portion, the length of which exceeds the respective lengths of the intermediate portion 10 and the tip, and is formed with a plurality of fins.
Øvelsesammunitionen er beregnet til at udgøre et mere økonomisk fordelagtigt alternativ til den kampammunition, som den er beregnet til at erstatte under øvelse. Et krav til øvelsesammunitionen er således, at den har i det mindste hovedsagelig samme ballistik som den pågældende kamp-15 ammunition. Der kendes en mængde øvelsesammunition, som opfylder dette krav.The exercise ammunition is intended to provide a more economically advantageous alternative to the combat ammunition it is intended to replace during exercise. A requirement for the exercise ammunition is that it has at least essentially the same ballistics as the combat-15 ammunition in question. A quantity of exercise ammunition is known which meets this requirement.
For at kravet til hovedsagelig samme ballistik ud til skud rækkevidde skal kunne opfyldes, er man hidtil gået ud fra, at f.eks. maksimale skudrækkevidder for den pågældende ammunition skal svare til den, som gælder 20 for den kampammunition, der skal erstattes. Dette har på sin side medført, at man måtte afspærre forholdsvis store områder ved de pågældende øvelsesskydninger.In order to be able to fulfill the requirement for essentially the same ballistics out of shot range, it has so far been assumed that e.g. the maximum firing ranges of the ammunition in question must correspond to that of 20 for the combat ammunition to be replaced. This, in turn, meant that relatively large areas had to be closed off during the exercise shoots in question.
Ammunitionsenheden ifølge den foreliggende opfindelse tager sigte på at løse bl.a. problemet med at kunne formindske kravet til tilgængelige 25 skydebanelængder. Opfindelsen udnytter i dette tilfælde erkendelsen af, at en spids i form af en spike giver fordele, bl.a. set ud fra et stabilitetssynspunkt. Det, der i det væsentlige kan anses for at være karakteristisk for den nye ammunitionsenhed, er i dette tilfælde, at den forreste spidsformede del udgøres af en i og for sig tidligere kendt cylinderformet 30 spids, såkaldt "spike", hvis diameter er væsentligt reduceret i forhold til mellemdelens diameter, og hvis længde er 1,6-2,0 gange mellemdelens diameter, og at halepartiet er udformet på en sådan måde, at finnerne med fuldt kalibermål strækker sig langs i det væsentlige hele halepartiets længde og forrest slutter sig til den bageste del af mellemdelen.The ammunition unit of the present invention is intended to solve, inter alia, the problem of being able to reduce the requirement for available 25 shooting range lengths. In this case, the invention utilizes the recognition that a spike in the form of a spike provides advantages, i. from a stability point of view. What can essentially be considered to be characteristic of the new ammunition unit is in this case that the anterior tip portion is constituted by a previously known cylindrical tip, so-called "spike", the diameter of which is substantially reduced. in relation to the diameter of the middle part, the length of which is 1.6-2.0 times the diameter of the middle part, and that the tail portion is formed in such a way that the full-caliber fins extend along substantially the entire length of the tail portion and foremost the posterior part of the middle part.
35 Det væsentlige i dette tilfælde er længden af den cylindriske spids i forhold til det ydre kalibermål af mellemdelen. I overensstemmelse med en foretrukket udførelsesform skal den nævnte længde i dette tilfælde være 2The essential in this case is the length of the cylindrical tip relative to the outer caliber gauge of the intermediate member. In accordance with a preferred embodiment, the said length in this case must be 2

1,6 - 2,0 gange mellemdelens diameter, fortrinsvis 1,65 - 1,85 med en absolut foretrukket værdi på ca. 1,7 gange mellemdelens diameter.1.6 to 2.0 times the diameter of the intermediate member, preferably 1.65 to 1.85 with an absolute preferred value of approx. 1.7 times the diameter of the middle part.
Videreudviklinger af opfindelsens grundtanke omfatter yderligere konkrete opgaver, bl.a. når det drejer sig om halepartiets konstruktion.Further developments of the basic idea of the invention include further concrete tasks, i.a. when it comes to tail construction.
5 Ved at anvende en spids i form af en spike fås der omkring denne et dødluftområde ved overlydshastighed, således at den mod ammunitionsenhedens flyveretning vendende radiale flade ikke udøver nogen bremsende effekt på ammunitionsenheden. Ved underlydshastighed strømmer luften derimod langs spidsens kappeflade og nævnte radiale flade, således at den-10 ne sidste udøver en stor bremsevirkning på ammunitionsenheden, der således kan bevare en i det væsentlige upåvirket ballistisk bane, så længe den bevæger sig med overlydshastighed, men får en hurtig afbremsning straks, når den går over til underlydshastighed. Den nævnte afbremsning medfører, at ammunitionsenheden kommer til at få sin væsentligt reducerede 15 maksimale skudrækkevidde. Den anvendte spids har en hovedsagelig stabilitetsøgende virkning både ved over- og underlydshastigheder og under selve gennemgangen af lydmuren. Ved anvendelse af den foreslåede spids forøges afstanden mellem Tp og T^-punkterne effektivt med en afstandsværdi, som svarer til indtil et kaliber. Halepartiets foreslåede form bidra-20 ger også til nævnte stabilitetsfunktion.5 By using a tip in the form of a spike, a dead air area is obtained around this at a supersonic velocity, so that the radial surface facing the ammunition unit's flight direction exerts no braking effect on the ammunition unit. At subsonic velocity, by contrast, the air flows along the casing surface of said tip and said radial surface, so that the latter exerts a large braking action on the ammunition unit, thus being able to maintain a substantially unaffected ballistic trajectory as long as it moves at supersonic velocity but receives a fast braking immediately when switching to sub-speed. The said braking means that the ammunition unit will have its substantially reduced 15 maximum firing range. The tip used has a mainly stability-enhancing effect both at upper and lower sound rates and during the passage of the sound wall itself. Using the proposed tip, the distance between the Tp and T ^ points is effectively increased by a distance value corresponding to up to one caliber. The tail shape's proposed shape also contributes to said stability function.
Den nye ammunitionsenheds form bidrager til, at der kan anvendes en effektiv og dermed økonomisk fremstillingsmåde med kold flydepresning. Ved den kolde flydepresning opnås der automatisk en forøget styrke, som overflødiggør f.eks. hærdning. Derved elimineres farerne for, at der under 25 fremstillingen fremkommer f.eks. skæve finner på grund af hærdningen.The shape of the new ammunition unit contributes to the use of an efficient and thus economical production method with cold float pressing. In the cold float pressing, an increased strength is automatically obtained, which makes, for example, superfluous. hardening. This eliminates the dangers of producing e.g. crooked fins due to curing.
Den kolde flydepresning medfører, at ammunitionsenheden presses i ét trin, hvilket bevirker, at ammunitionsenheden opnås i hovedsagen i færdig tilstand. Det bliver kun nødvendigt at foretage drejning og påføring af bælte og eventuelt styrevulst. Ammunitionsenhedens udformning 30 og fremgangsmåden ved fremstilling af denne medfører besparelser, hvad angår materiale, energi og omkostninger.The cold float pressure causes the ammunition unit to be pressed in one step, which results in the ammunition unit being obtained in the finished state in the main. It will only be necessary to turn and apply belt and possibly steering wheel. The design of the ammunition unit 30 and the method of making it result in savings in material, energy and cost.

Fig. 1-3 tager sigte på at vise et øvelsesprojektil, der er forsynet med 20 en hovedsagelig cylinderformet del 1, en spids 2, som slutter sig til denne, og et haleparti 3. Projektilspidsen 2 dannes af en såkaldt spike, der i princippet er tidligere kendt. Spidsen har hovedsagelig cylinderform og har en diameter d, som er væsentligt reduceret i forhold til den cylindriske del 1's diameter D, og som eksempel kan nævnes, at spidsens diameter d 25 er ca. 1/3 af mellemdelens diameter D. Halepartiet er forsynet med finner 3a, hvoraf der f.eks. kan være seks.FIG. 1-3 are intended to show an exercise projectile provided with a substantially cylindrical portion 1, a tip 2 joining it, and a tail portion 3. The projectile tip 2 is formed by a so-called spike, which is known. The tip is mainly of cylindrical shape and has a diameter d which is substantially reduced in relation to the diameter D of the cylindrical part 1, and as an example it can be mentioned that the diameter d 25 of the tip is approx. 1/3 of the diameter of the middle part D. The tail portion is provided with fins 3a, of which e.g. can be six.
Den hovedsageligt cylinderformede spids 2 er tildelt en længde L^, som i det viste tilfælde er ca. 1,7 gange mellemdelens diameter D. Den nævnte længde kan varieres i afhængighed af kaliber, ammunitionsart 30 o.s.v. mellem 1,6 og 2,0 gange nævnte diameter D, fortrinsvis mellem 1,65 og 1,85 gange nævnte diameter.The substantially cylindrical tip 2 is assigned a length L 2, which in the case shown is approx. 1.7 times the diameter of the intermediate member D. Said length can be varied depending on caliber, ammunition type 30, etc. between 1.6 and 2.0 times said diameter D, preferably between 1.65 and 1.85 times said diameter.
Halepartiets længde L2 er større end spidsen 2's og mellemdelen 1's respektive længder, henholdsvis og l_3· Halepartiets finner strækker sig langs den væsentlige del af halepartiets længde med fuldt kaliber-35 mål. I tilknytning til mellemdelen er finnerne formindsket under kalibermålet og har skråtstillede overkanter 3a', der strækker sig udefter og bagud regnet fra mellemdelen. Mel lemdel en er bagtil forsynet med en flade 4The tail portion length L2 is greater than the respective lengths of the tip 2 and the intermediate portion 1, respectively, and l3. · The tail portion fins extend along the substantial portion of the tail portion length with full caliber dimensions. Adjacent to the intermediate member, the fins are diminished below the caliber target and have inclined upper edges 3a 'extending outwards and backwards from the intermediate member. Flour limb one is at the rear provided with a surface 4

la, der i hovedsagen har form som en afkortet kegle. Den nævnte flade hælder i forhold til projektilets længdeakse under en vinkel a, der er mellem 10 og 20°, fortrinsvis ca.l5°. Den koniske flades smalleste del vender mod og er knyttet til finnernes ender. Den koniske flades længde 5 er 1-3%, fortrinsvis 2% af projektilets totale længde. Nævnte koniske flade bidrager til at styre den langs mellemdelen i dennes længderetning fejende luftstrøm nedefter mellem halepartiets finner 3a for derved at forbedre projektilets stabilitet.la, which in the main proceedings has the shape of a truncated cone. Said surface slopes with respect to the longitudinal axis of the projectile at an angle α which is between 10 and 20 °, preferably about 125 °. The narrowest part of the conical surface faces and is attached to the ends of the fins. The length 5 of the conical surface is 1-3%, preferably 2% of the total length of the projectile. Said conical surface contributes to controlling the air flow sweeping along the intermediate length downwards between the tail portion fins 3a, thereby improving the stability of the projectile.
Mellemdelens længde er i det viste tilfælde kortere end både spid-10 sen og halepartiet. Mellemdelen bærer et forreste ringformet ydre spor og et bageste ringformet ydre spor til en forreste styrevulst 4 og et bælte 5. Både styrevulsten og bæltet er udført af plast, f.eks. acetal eller tilsvarende.In the case shown, the length of the intermediate portion is shorter than both the tip and the tail portion. The intermediate member carries a front annular outer groove and a rear annular outer groove for a front guide bead 4 and a belt 5. Both the guide bead and belt are made of plastic, e.g. acetal or equivalent.
I fig. 3 er projektilets tyngdepunkt vist ved Tp, og dets tryk-15 centrum med T^,, medens den for stabiliteten væsentlige afstand mellem Tp og Tc er betegnet med A.In FIG. 3, the center of gravity of the projectile is shown at Tp, and its center of pressure with T 1, while the significant distance between Tp and Tc for stability is denoted by A.
Fig. 4a og 4b viser luftstrømningsforholdene ved projektilets henholdsvis overlyds- og underlydshastighed. I fig. 4a er kompressionsstødbølgen antydet ved 6, og et dødluftområde i form af et rotationssymmetrisk 20 område omkring spidsen er betegnet med 7. Det nævnte område begrænses af sideyderfladerne på spidsen 2, en radial forreste flade 1b på mellemdelen samt en ret konisk formet, tænkt yderflade 8, der strækker sig fra spidsens forreste endeflade til den radiale flade 1b's periferi. En uforstyrret strømning foregår i pilen 9's retning langs den rette konisk 25 formede yderflade 8 og medfører, at der ikke foreligger nogen bremsende virkning fra den radiale flade.FIG. Figures 4a and 4b show the air flow conditions at the projectile and sound noise velocity, respectively. In FIG. 4a, the compression shock wave is indicated by 6, and a dead air region in the form of a rotationally symmetrical region around the tip is denoted by 7. Said area is limited by the side outer surfaces of the tip 2, a radially anterior surface 1b of the intermediate member, and a rather conical shaped, imagined outer surface 8. extending from the anterior end surface of the tip to the periphery of the radial surface 1b. An undisturbed flow takes place in the direction of the arrow 9 along the straight conical 25 outer surface 8 and causes no braking effect from the radial surface.
Det ovennævnte indebærer, at projektilet, sålænge det har overlydshastighed, kan antage en ballistisk bane, som svarer til den ballistiske bane for et projektil forsynet med ogivalformet, konisk formet eller på 30 anden måde udformet næse. Anvendelsen af den som spike udformede spids medfører en fordelagtig tilbageflytning i projektilets længderetning af Tp og Tc samt en fordelagtig lang afstand A, hvilke sammen garanterer en tilstræbt høj stabilitet for projektilet i og for sig. Det skal i denne forbindelse bemærkes, at projektilet bliver stabilt, ikke alene ved over-35 lydshastighed, men også ved gennemgang af lydmuren og ved underlydshastighed.The above implies that the projectile, as long as it has a supersonic velocity, can assume a ballistic trajectory which corresponds to the ballistic trajectory of a projectile equipped with ogival, conical or otherwise shaped nose. The use of the spike-shaped tip results in an advantageous relocation in the longitudinal direction of the projectile of Tp and Tc as well as an advantageously long distance A, which together guarantee a high stability of the projectile per se. In this connection, it should be noted that the projectile becomes stable, not only at over-speed of sound, but also at the passage of the sound-wall and at under-speed.

Fig, 4b viser strømningsforholdene ved underlydshastughed. Luftstrømningen 10 kan foregå langs spidsens sideyderflade og den i det væsentlige radiale flade 1b på mellemdelen 1. Dette medfører, at den radiale flade 1b vil udøve en bremsevirkning på projektilet, som reducerer dettes 5 maksimale skud- eller flyverækkevidde væsentligt, f.eks. til kun ca. halvdelen af det, der gælder for konventionel kampammunition, som øvelsesprojektilet er beregnet til at erstatte.Fig. 4b shows the flow conditions at low noise speed. The air flow 10 can take place along the lateral surface of the tip and the substantially radial surface 1b of the intermediate member 1. This causes the radial surface 1b to exert a braking effect on the projectile which substantially reduces its maximum firing or flight range, e.g. for only approx. half of what applies to conventional combat ammunition that the exercise projectile is intended to replace.
Fig. 5a og 5b skal vise øvelsesprojektilets ballistiske egenskaber i forhold til en konventionel kampgranat. Som eksempel på nævnte kampgra-10 nat er der i dette tilfælde valgt en af Bofors markedsført 9 cm kampgranat, model 77, der har en vægt på ca. 3,7 kg. Øvelsesprojektilet har også kaliber 9 cm og har en vægt på ca. 3 kg. Diagrammets y-akse viser banens højde i meter og x-aksen skudafstanden, ligeledes i meter. Den maksimale skudafstand for den pågældende ammunition er 800 m.FIG. 5a and 5b are intended to show the ballistic properties of the exercise projectile relative to a conventional combat grenade. In this case, one of Bofor's 9 cm combat grenades, model 77, which has a weight of approx. 3.7 kg. The exercise projectile also has a caliber 9 cm and has a weight of approx. 3 kg. The y-axis of the diagram shows the height of the web in meters and the x-axis shot distance, also in meters. The maximum firing distance for the ammunition in question is 800 m.
15 Kurven a viser banen for kampgranaten og kuven b for øvelsesprojek tilet, når granaten skydes ud af løbet med Vg = 670 m/s og øvelsesprojektilet med Vg = 715 m/s. Kurverne viser, at ballistikken for skydning på en afstand op til maksimal skydeafstand bliver væsentligt den samme, hvilket bevirker, at der kan opnås en fuldgod træning af kanonbetjeningen 20 ved skydning med det viste øvelsesprojektil.15 Curve a shows the trajectory of the combat grenade and the bullet b for exercise project tilted when the grenade is fired out of the race at Vg = 670 m / s and the exercise projectile with Vg = 715 m / s. The curves show that the ballistics of shooting at a distance up to maximum shooting distance will be substantially the same, which means that a complete training of the cannon operation 20 can be obtained by shooting with the exercise projectile shown.
Diagrammet 5b viser ballistikkurverne for maksimal skudrækkevidde, idet y-aksen viser højden i meter og x-aksen horisontalafstanden i meter. Kurven a1 for kampgranaten ifølge ovenstående viser i dette tilfælde en maksimal skudrækkevidde, som er ca. dobbelt så lang (6000 m) som den 25 maksimale skudrækkevidde for øvelsesprojektilet. Dette har sin forklaring i, at øvelsesprojektilet bremses kraftigt ned, når det overgår til underlydshastighed. Det skal nævnes, at den viste konstruktion af øvelsesprojektilet er stabil indenfor hele sit hastighedsområde, f.eks. mellem 0 og 3 gange lydens hastighed. Dette indebærer, at øvelsesammunitionen 30 bliver let at spore.The diagram 5b shows the ballistic curves for maximum firing range, the y-axis showing the height in meters and the x-axis the horizontal distance in meters. The curve a1 for the fighting grenade according to the above shows in this case a maximum firing range which is approx. twice as long (6000 m) as the 25 maximum firing range for the exercise projectile. This has its explanation in that the exercise projectile slows down sharply when it switches to sub-speed. It should be mentioned that the shown construction of the exercise projectile is stable throughout its speed range, e.g. between 0 and 3 times the speed of sound. This means that the exercise ammunition 30 becomes easy to track.
Det beskrevne øvelsesprojektil kan med fordel fremstilles ved kold flydepresning. Et udgangsemne placeres i så fald i et værktøj til kold flydepresning, og med værktøjet fremstilles projektilet i et eneste trin, der samtidig medfører presning af spidsen og finnerne. Derefter foregår 35 der en efterfølgende mindre kalibermåldrejning.The described exercise projectile can advantageously be produced by cold float pressing. In this case, an output blank is placed in a cold float tool, and with the tool the projectile is manufactured in a single step, which simultaneously causes the tip and the fins to be pressed. Subsequently, a subsequent smaller caliber target rotation takes place.

6 I fig. 6a er der vist et emne 11, der anvendes som udgangsmateriale til fremstilling af f.eks. nævnte 9 cm øvelsesprojektil. Emnet har cylindrisk form med en diameter på 92 mm og en længde på 200 mm. Værktøjshalvdelene er antydet ved 12 og 12'. Presning foregår i et ene-5 ste trin og forudsættes at være fuldført i fig. 6b, hvor værktøjets delingsplan er betegnet med De og formningsrummet med F.6 In FIG. 6a there is shown a blank 11 which is used as a starting material for preparing e.g. said 9 cm exercise projectile. The workpiece has a cylindrical shape with a diameter of 92 mm and a length of 200 mm. The tool halves are indicated at 12 and 12 '. Pressing takes place in a single step and is assumed to be completed in FIG. 6b, wherein the partition plane of the tool is denoted by You and the molding space by F.
Når det færdigt pressede øvelsesprojektil er udtaget fra værktøjet, drejes det ned til de mål, som fremgår af f.eks. fig. 3. Projektilet får en længde på ca. 465 mm.When the finished pressed exercise projectile is removed from the tool, it is turned down to the targets shown in e.g. FIG. 3. The projectile has a length of approx. 465 mm.
10 Den kolde flydepresning som sådan er tidligere velkendt og skal derfor ikke beskrives nærmere her.10 The cold float press as such is well known in the past and is therefore not to be described in more detail here.
