Description

Die Erfindung betrifft eine Bremseinrichtung gemäß dem Oberbegriff des Anspruches 1. Eine solche Bremseinrichtung ist aus der DE 100 23 345 A1 bekannt.The invention relates to a braking device according to the preamble of claim 1. Such a braking device is known from DE 100 23 345 A1 known.

Vorliegender Erfindung liegt die technische Problemstellung zugrunde, eine Bremseinrichtung gattungsgemäßer Art dahingehend weiterzubilden, dass sich einerseits ein spürbar vergrößerter Bremseffekt bei andererseits stabiler Ballistik während des Initiierens der Bremseinrichtung ergibt.The present invention is based on the technical problem of developing a braking device of the generic type in such a way that, on the one hand, a noticeably increased braking effect results on the other hand in stable ballistics during the initiation of the braking device.

Dieser Aufgabenstellung liegt die Erkenntnis zugrunde, dass eine sternförmige Anordnung von radial ausklappbaren Bremssegmenten trotz der Wirbelbildungen in den Lücken zwischen den Bremssegmenten noch nicht die wünschenswerte Bremsbeiwerte zum möglichst raschen und definierten Übergang aus der ballistischen Verbringungsbahn in eine versteilerte Abstiegsbahn erbringt. Die Bremswirkung lässt sich zwar verbessern, wenn die freien Zwickel zwischen den einzelnen Bremssegmenten von spitzwinklig dreiecksförmigen Tüchern überspannt werden, die beim Verbringen aus dem Geschütz zunächst noch zusammen mit den Bremssegmenten in den Stauraum unter einer Halterungs-Haube eingefaltet sind und dann mit dem Absprengen der Haube zum fliehkraftgestützten Aufrichten freigegeben werden; aber die Kombination aus scharnierartig angelenkten Bremssegmenten und dazwischen eingespannten Textilien ist außerordentlich montageaufwendig und weist darüber hinaus den Nachteil auf, dass aufgrund der kompakten Pressung im Stauraum lokale mechanische Beanspruchungen zur bereichsweisen Beschädigung der textilen Lückenfüller führen können. Nachdem es ohnehin kritisch ist, alle diese Lückenfüller durch das Ausschwenken der mantelschalenförmigen Bremssegmente rundum gleichzeitig zu spannen, so daß keine unsymmetrischen Anströmkräfte auftreten und zu unkontrollierbarer Ablenkung aus der bisherigen Flugbahn führen können, sind derartige Störungen gar nicht mehr zu vermeiden, wenn die Dreiecktücher lokal beschädigt sind und somit in nicht vorherbestimmbaren Sektoren um die Projektilogive herum ein vom Standard abweichendes Bremsverhalten erbringen.This task is based on the finding that a star-shaped arrangement of radially expandable brake segments, despite the formation of vortices in the gaps between the brake segments, does not yet provide the desirable brake coefficients for the fastest possible and more defined transition from the ballistic transfer path to a steepened descent path. Although the braking effect can be improved if the free gussets between the individual brake segments are spanned by acute-angled triangular wipes, which are initially folded together with the brake segments in the storage space under a support hood when moving out of the gun and then with the blasting of Hood to be released for centrifugal assisted erection; but the combination of hinge-hinged brake segments and textiles clamped therebetween is extremely difficult to install and also has the disadvantage that local mechanical stresses due to the compact pressure in the storage space to the area Damage to the textile gap filler can lead. After all, it is critical to tension all these gap fillers at the same time by swinging out of the shell shell-shaped brake segments, so that no asymmetrical flow forces occur and can lead to uncontrollable distraction from the previous trajectory, such disturbances are no longer avoidable when the triangular cloths locally are damaged and thus provide non-standard braking behavior in non-predictable sectors around the projectile log.

Die oben umrissene Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kombination der im Hauptanspruch angegebenen Merkmale verwirklicht ist, wonach die bisher diskreten Bremssegmente praktisch zu einem integralen textilen Gebilde von der Form eines die Ogive umgebenden, zum flachen stumpfwinkligen Hohlkegelstumpf angestellten Kreisringes mit nach voraus weisender kleiner Basis aufgespannt werden.The above outlined object is achieved in that the combination of the features specified in the main claim is realized, according to which the previously discrete brake segments practically to an integral textile structure of the shape of an ogive surrounding the flat obtuse hollow truncated cone annealed annulus with pointing ahead smaller Base be spanned.

Zur näheren Erläuterung der Erfindung, ihrer Vorteile und Weiterbildungen wird außer auf die weiteren Ansprüche auch auf die nachstehende Beschreibung eines in der Zeichnung unter Beschränkung auf das Wesentliche stark abstrahiert aber angenähert maßstabsgerecht skizzierten bevorzugten Realisierungsbeispiels für die erfindungsgemäße Bremseinrichtung verwiesen. In der Zeichnung zeigt:

In the drawing shows:

Wie im Hauptpatent näher dargestellt, weist ein Zünder 11, der zum Einschrauben in die Ogive eines Artillerie-Projektiles 12 ausgelegt ist, in seiner kegelstumpfförmigen Mantelfläche 13 einen umlaufend radial eingesenkten Stauraum 14 auf. Dieser trägt seiner Rückwand 25 axial gegenüber, also in Flugrichtung vor dem Stauraum 14 einen Ring 15, an den der Innenumfang 31 eines in Wirkstellung koaxial kreisscheibenförmig umlaufenden Bremselementes in Form eines der Flugrichtung entgegen aufspannbaren textilen Schirmes 16 angelenkt ist. Dieses textile Bremselement ist in seiner Depot- und Verbringungsstellung vom Ring 15 her nach rückwärts gleichförmig um die Projektil-Längsachse 17 herum in den Stauraum 14 eingefaltet und von einer Haube übergriffen, bis es durch das Absprengen der Haube zum fliehkraftbedingten radialen Ausstellen in die Schirmform freigegeben wird. Damit die bei dieser radialen Ausstellbewegung unter Rotation des Projektiles 12 auftretende Corrioliskraft im Anlenkbereich des Bremselementes an den Ring 15 gezielt abgebaut werden kann, ist es zweckmäßig, bei der axialen Einspannung des Ringes 15 ein vorübergehendes Durchdrehen relativ zum Projektil 12 zuzulassen, bis der Kräfteabbau zur Beendigung dieses Schlupfes führt.As shown in detail in the main patent, an igniter 11, which is designed for screwing into the ogive of an artillery projectile 12, in its frustoconical lateral surface 13 on a circumferentially radially recessed storage space 14. This carries its rear wall 25 axially opposite, so in the direction of travel before the storage space 14, a ring 15 to which the inner circumference 31 of a coaxial in operative position circular disk-shaped braking element is hinged in the form of a flight direction against the stretchable textile screen 16. This textile brake element is folded in its depot and transfer position from the ring 15 forth uniformly around the projectile longitudinal axis 17 around in the storage space 14 and overlapped by a hood until it is released by the blowing off of the hood for centrifugal radial issuing in the umbrella shape , In order that the occurring during this radial Ausstellbewegung under rotation of the projectile 12 Corrioliskraft in the articulation of the brake element can be selectively reduced to the ring 15, it is expedient to allow a temporary spin relative to the projectile 12 in the axial clamping of the ring 15 until the loss of power to Completion of this slip leads.

Die den umlaufenden Stauraum 14 mit dem eingefalteten Bremselement übergreifende Haube zur Ergänzung der Kontur der Kegelmantelfläche 13 Zünders 11 im Anschluss an die Außenmantelfläche 27 des Projektiles 12 ist vorne, vor der kleinen Basis des Bremsschirmes 16, als dickwandiger Hohlzylinder ausgelegt. Daran schließt sich einstückig nach rückwärts eine dagegen sehr dünne hohlkegelstumpfförmige Wandung an. Dieser dünnwandige Bereich ist konstruktiv dafür ausgelegt, sich achsparallel bis zum Hohlzylinder vor sich erstreckender Sollbruchstellen in einzelne, dann unter dem Einfluß der Zentrifugalkraft radial vom rotierenden Stauraum 14 abhebende Schalenstücke zu zerlegen. Dafür greift wie beim Hauptpatent der Stiel einer pilzförmigen Aufnahme 18 für mehrere über den Umfang gleichförmig verteilte, radial wirkende pyrotechnische Kraftelemente 19 von vorne, der Flugrichtung also entgegen, axial durch den Hohlzylinder der Haube und durch den Anlenk-Ring 15 hindurch in eine Fassung in der mechanischen Struktur des Zünders 11 ein. Die dadurch an der Innenperipherie des Hohlzylinders gelegenen Kraftelemente 19 dienen dazu, bei Zündung den auf der Aufnahme 18 lagernden Hohlzylinder der Haube radial Aufzusprengen und damit diese Abdeckhaube in definierte Stücke zerlegt vom Stauraum 14 abheben zu lassen.The circumferential storage space 14 with the folded brake element cross hood to supplement the contour of the conical surface 13 detonator 11 following the outer circumferential surface 27 of the projectile 12 is front, before the small base of the brake 16, designed as a thick-walled hollow cylinder. This is followed in one piece to the rear against a very thin hollow frustoconical wall. This thin-walled area is designed to disassemble axially parallel to the hollow cylinder in front of extending breaking points in individual, then under the influence of centrifugal force radially from the rotating storage space 14 contrasting shell pieces. For attacks as in the main patent, the stem of a mushroom-shaped receptacle 18 for a plurality of uniformly distributed over the circumference, radially acting pyrotechnic force elements 19 from the front, the flight direction so, axially through the hollow cylinder of the hood and through the Anlenk-ring 15 through into a socket in the mechanical structure of the igniter 11 a. The thus located on the inner periphery of the hollow cylinder force elements 19 are used to radially aufzusprengen when stored on the receptacle 18 hollow cylinder of the hood and thus disassemble this cover disassembled into defined pieces of storage space 14.

Die radiale pyrotechnische Beanspruchung des an der Aufnahme 18 ruhenden Hohlzylinders am vorderen Ende der Verbringungshaube führt also zum Entfernen der Stauraumwandung und damit zum Freigeben des Bremsschirmes 16, der sich nun zentrifugal aus dem Stauraum 14 heraus um den Ring 15 herum als dessen kleinere Hohlkegelstumpf-Basis in eine zur Achse 17 nicht ganz orthogonale Wirkstellung ringscheibenförmig rasch und formstabil aufspannt.The radial pyrotechnic stress of resting on the receptacle 18 hollow cylinder at the front end of the delivery hood thus leads to the removal of the storage space wall and thus to release the brake parachute 16, which now centrifugally out of the storage space 14 around the ring 15 around as its smaller hollow truncated cone base in a not completely orthogonal to the axis 17 working position annular disc shape spans quickly and dimensionally stable.

Dieses fliehkraftbedingte Ausstellen des ringscheibenförmigen Bremsschirmes 16 wird noch dadurch gefördert, daß - der Anlenkung am Ring 15 gegenüber - der Schirm wenigstens durch Saumnähte, gegebenenfalls aber auch durch Einnähen von Verstärkungen im Vergleich zur Tuchfläche mit einer definierten Massenansammlung 29 ausgerüstet ist, um das Trägheitsmoment für ein rasches und stabiles Ausstellen aus der eingefalteten Lage in die vom Schnitt her vorgegebene Endform im Interesse einer schnell wirksamen großen, symmetrischen Anströmfläche für maximale Bremswirkung zu steigern.This centrifugal force issuing of the annular disc brake screen 16 is further promoted by the fact that - the shield at least by seam seams, but optionally also by sewing reinforcements compared to the cloth surface with a defined mass accumulation 29 is equipped with the moment of inertia for To increase a rapid and stable issuing from the folded position in the final shape given from the cut in the interest of a fast-acting large, symmetrical inflow surface for maximum braking effect.

Wie in der Zeichnung skizziert handelt es sich also beim hier so genannten Bremsschirm 16, der aber gegen seine Außenmantelfläche angeströmt wird, im wesentlichen um eine den Befestigungsring 15 ringscheibenförmig umgebendes textiles Gebilde. Das ist allerdings vom Schnitt her dafür ausgelegt, unter Einfluß der Zentrifugalkräfte nicht in eine im wesentlichen ebene und daher flattergefährdete textile Scheibe aufgespannt zu werden, sondern nur bis zu einem relativ großen Winkel gegenüber der Projektilachse 17, um im maximal ausgestellten Zustand ohne Flattererscheinungen längs des Randes stets die gleiche kegelstumpfförmige Geometrie stabil einhalten zu können. Dafür ist das an sich in der Ebene kreisrund zugeschnittene Tuch 33 des Schirmes 16 mit radialen Sektorschnitten oder Nähfalten längs schmaler Ausschnitte in Umfangsrichtung so gerafft, daß der Außenumfang des Schirmes 16 in seiner kegelstumpfförmig aufgestellten Wirkstellung kleiner als der auf den Radius bezogene Kreisumfang ist. Das führt zu einem auch unter der Anströmung ringsum gleichförmig aufgebauschten, mechanisch stabilen und geometrisch definierten kegelstumpfmantelförmigen Bremsschirm 16, der in Flugrichtung orientiert ist, dessen kleine Basis also gleich bei der Aufnahme 18 mit dem Ring 15 liegt, während die große Basis von dort nach rückwärts, zum Projektil 12 hin orientiert ist.As sketched in the drawing, in the case of the so-called braking screen 16, which, however, flows against its outer circumferential surface, essentially a textile structure surrounding the fastening ring 15 in the form of an annular disk. However, this is designed from the cut, under the influence of centrifugal forces not to be clamped in a substantially flat and therefore flatter end textile disc, but only up to a relatively large angle relative to the projectile axis 17, in the maximum issued state without fluttering along the Edge always the same frusto-conical geometry stable to be able to comply. For this purpose, the cloth 33 of the screen 16, which is circular in itself, is so gathered in the plane with radial sector cuts or sewing folds along narrow cutouts in the circumferential direction that the outer circumference of the shield 16 is smaller than the circle circumference based on the radius in its frustoconical active position. This leads to a uniformly inflated even around the flow uniformly, mechanically stable and geometrically defined truncated cone-shaped Bremsschirm 16, which is oriented in the direction of flight, so its small base is equal to the recording 18 with the ring 15, while the large base from there to the rear , oriented towards the projectile 12.

Dieser breite ringscheibenförmige Bremsschirm 16 kann mit seinem Tuch 33 längs dessen Innendurchmessers unmittelbar den Ring 15 umschlingend angelenkt sein. Zweckmäßiger ist es jedoch, das Tuch 33 strahlen- oder speichenförmig mit ebenfalls textilen Verstärkungsbändern 34 zu benähen, die einerseits an den Außenumfang 32 anschließen und sich von dort radial über den Innenumfang 31 hinaus bis zum Ring 15 erstrecken, dessen Außenendurchmesser etwas kleiner als derjenige des Innumfangs 31 ist. So ist das kreisringförmige, kegelstumpfförmig angestellte Tuch 33 nur mittels der Verstärkungsbänder 34 an den Ring 15 gefesselt, was ein gleichmäßiges Ausstellen beim Auftauchen aus dem Stauraum 14 fördert und Beschädigungen des Tuches 33 beim anfängliche Durchrutschen des Ringes 15 zuverlässig vermeidet.This wide annular disc-shaped brake shield 16 can be hinged with its cloth 33 along the inner diameter immediately surrounding the ring 15. It is more expedient, however, to sew the cloth 33 in the form of a ray or spoke, likewise with textile reinforcing tapes 34, on the one hand to the outer circumference 32 and from there extend radially beyond the inner circumference 31 out to the ring 15, whose outer diameter is slightly smaller than that of the Innumfangs 31. Thus, the annular, frustoconical salaried cloth 33 is tied only by means of the reinforcing bands 34 to the ring 15, which promotes a uniform issuing when emerging from the storage space 14 and damage of the cloth 33 at the initial slippage of the ring 15 reliably avoids.

Um also das fliehkraftbedingt radial ausstellende textile Bremselement 16 rasch in eine auch unter Anströmungsbedingungen stets definierte, formstabile Kontur zu bringen, ist ein kreisringförmig zugeschnittenes Tuch 33 durch radial verlaufende Abnäher derart mit einem verkleinerten Außenumfang 32 ausgestattet, daß die Aufspannbewegung dadurch auf die Form eines flachen stumpfwinkligen Hohlkegelstumpfes begrenzt wird, der mittels längs Erzeugender der Kegelmantelfläche aufgebrachter Verstärkungsbänder 34 am Innenumfang 31 der in Flugrichtung nach vorne weisenden kleinen Basis einen radialen Abstand überbrückend an den Haltering 15 angelenkt ist und rückwärtig, längs des Außenumfangs 32, mit einer umlaufenden Masseansammlung 29 zur Verstärkung der zentrifugalen Ausstellkräfte ausgestattet ist; wobei der Ring 15 im vorderen Stirnbereich des Stauraumes 14, relativ zum Projektildrall vorübergehend durchrutschend, in die Kontur des Zünders 12 axial eingespannt ist.So as to rapidly bring the centrifugal force radially exhibiting textile brake element 16 in a well-defined under flow conditions, dimensionally stable contour, a circular cut cloth 33 is equipped by radially extending dart so with a reduced outer circumference 32, characterized in that the clamping movement to the shape of a flat obtuse-angled hollow truncated cone is limited, by means of longitudinal generatrix of the conical surface applied reinforcing ribbons 34 on the inner circumference 31 of the forwardly pointing small base a radial distance bridging to the retaining ring 15 is hinged and rearwardly, along the outer periphery 32, with a circumferential mass accumulation 29 for reinforcement equipped with centrifugal release forces; wherein the ring 15 in the front end region of the storage space 14, temporarily slipping relative to the projectile twist, is axially clamped in the contour of the igniter 12.
