Definitions
- the invention relates to a braking device according to the preamble of claim 1, as is the subject of the main patent.
- 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 there is a noticeably increased braking effect with on the other hand stable ballistics during the initiation of the braking device.
- This task is based on the knowledge that a star-shaped arrangement of radially fold-out brake segments, despite the formation of eddies in the gaps between the brake segments, does not yet provide the desirable braking coefficients for the fastest and defined transition from the ballistic nerbring track to a taxed descent track.
- the braking effect can be improved if the free gussets between the individual brake segments are spanned by triangular-shaped cloths, which when they are brought out of the gun are first folded together with the brake segments into the storage space under a holder hood and then with the blasting off Hood to be released for centrifugal support; but the combination of hinge-like brake segments and textiles clamped in between them is extremely labor-intensive and has the further disadvantage that due to the compact pressure in the storage space, local mechanical stresses 2xn in some areas damage to the textile gap filler.
- Fig. 1 in the ogive area mounted on an artillery projectile detonator for warhead triggering, showing a ring-shaped textile brake element in the issued state and
- Fig. 2 shows the braking element as such in an end view.
- a detonator 11 which is designed for screwing into the ogive of an artillery projectile 12, has in its truncated cone-shaped outer surface 13 a storage space 14 which is recessed radially all round.
- This carries its rear wall 25 axially opposite, that is, in the direction of flight in front of the storage space 14, a ring 15 to which the inner circumference 31 of a brake element which is coaxial in the operative position and which is circular in the form of a disc is articulated in the form of a textile screen 16 which can be stretched against the direction of flight.
- the textile braking element is folded uniformly from the ring 15 backwards around the longitudinal axis 17 of the projectile into the storage space 14 and is overlapped by a hood until it breaks off into the shape of the dish due to centrifugal force due to centrifugal force is released. So that the under this radial tilting movement
- Rotation of the projectile 12 corriolis force occurring in the articulation region of the braking element on the ring 15 can be reduced in a targeted manner, it is expedient to allow the ring 15 to be temporarily rotated relative to the projectile 12 until the reduction in force leads to the end of this slip.
- the hood overlapping the circumferential storage space 14 with the folded-in brake element to complement the contour of the cone jacket surface 13 of the igniter 11 following the outer jacket surface 27 of the projectile 12 is designed at the front, in front of the small base of the brake screen 16, as a thick-walled hollow cylinder. This is followed in one piece by a very thin hollow cone-shaped wall. This thin-walled area is structurally designed to disassemble axially parallel to the hollow cylinder in front of predetermined breaking points in individual, then under the influence of centrifugal force radially lifting from the rotating storage space 14 shell pieces.
- the force elements 19 thus located on the inner periphery of the hollow cylinder serve to radially burst open the hollow cylinder of the hood, which is supported on the receptacle 18, and thus to allow this covering hood to be taken apart from the storage space 14 into defined pieces.
- Umbrella is at least equipped with a defined mass accumulation 29 by seam seams, but possibly also by sewing in reinforcements in comparison to the fabric surface, in order to quickly and stably lift out the folded position into the final shape specified by the cut in the interest of a quick effective large, symmetrical inflow surface for maximum braking effect.
- the so-called brake screen 16 which is flowed against its outer surface, is essentially a textile structure surrounding the fastening ring 15 in the form of an annular disk.
- this is designed not to be clamped under the influence of the centrifugal forces into a substantially flat and therefore flutter-prone textile disk, but only up to a relatively large angle with respect to the projectile axis 17, in order to be in the maximum flared condition without flutter to be able to maintain the same frustoconical geometry along the edge.
- the circularly cut cloth 33 of the screen 16 with radial sector cuts or sewing folds along narrow cut-outs in the circumferential direction is gathered in such a way that the outer circumference of the screen 16 in its conical ramp-shaped active position is smaller than the circumference based on the radius ,
- This wide annular disk-shaped brake screen 16 can be articulated with its cloth 33 directly looping around the ring 15 along its inner diameter. It is more expedient, however, to sew the cloth 33 in the form of a ray or a spoke with textile reinforcement tapes 34, which on the one hand are attached to the outer Connect the outer circumference 32 and from there extend radially beyond the inner circumference 31 to the ring 15, the outer diameter of which is somewhat smaller than that of the inner circumference 31.
- the circular, frustoconical cloth 33 is only attached to the ring 15 by means of the reinforcing bands 34, which promotes a uniform release when emerging from the storage space 14 and reliably prevents damage to the cloth 33 when the ring 15 initially slips.
- a circularly cut cloth 33 is equipped with a reduced outer circumference 32 by radial darts in such a way that the clamping movement thereby takes the form of a flat one is limited to an obtuse-angled hollow truncated cone, which is articulated by means of reinforcement bands 34, which are applied lengthways to the conical surface, on the inner circumference 31 of the small base pointing forward in the direction of flight, bridging a radial distance to the retaining ring 15 and on the rear, along the outer circumference 32, with a circumferential mass accumulation 29 is equipped to increase the centrifugal force; wherein the ring 15 in the front end region of the storage space 14, temporarily slipping relative to the projectile swirl, is axially clamped in the contour of the igniter 12.
