Description
Projectile and submunition with biasing body The present invention relates to a projectile in accordance with the preamble of claim 1, as well as a submunition in accordance with the preamble of claim 13.
In artillery and mortar projectiles, accelerations of up to 17,000 G occur during discharge. The discharge acceleration acting on various partial masses, such as shell, ejector charge, active body and the active masses worked into it, cause high inertia forces which temporarily place a high strain on the overall system of the projectile as well as on the associated single systems.
Projectiles, and in particular smoke projectiles of various calibers, have a construction wherein various submunitions are carried along in the projectile shell.
The submunitions have a construction in which the active mass body, e.g. smoke body, of active mass body sheath with bottom, support tube and lid, and corresponding active masses are worked into a steel casing.
Such projectiles having, for instance, smoke masses as active masses, are known, e.g., from US 5,454,324.
Further smoke projectiles are known from US 5,551,345.
A method for,manufacturing a smoke projectile charge is known from DE 28 41 815 C2. i
Pyrotechnic smoke active masses for charging into smoke-generating projectiles are known, e.g., from EP 0 106 334 A2.
All of the smoke projectiles mentioned in the above prior art, in particular those having large-caliber designs such as, e.g., in a 155-mm smoke projectile, may exhibit the drawbacks explained in the following: During discharge of, say, a 155-mm smoke projectile, the load on the smoke body in front of the projectile bottom amounts to approx. 2650 kN owing to the overlying smoke body column.
The smoke active masses generally include various charges, mostly on the basis of red phosphorus, as described, e.g., in EP 0 106 334 A2, wherein the smoke active masses generally comprise an igniter charge, a preliminary smoke charge as well as a main smoke charge, but also mixed charges of preliminary and main smoke.
The smoke active masses used generally are shock sensitive. If the above mentioned discharge load of 2650 kN is concurrently transmitted to the smoke active mass, this may result in a sudden reaction of the active mass even within the weapons tube.
Moreover during passage of the projectile through the weapons tube, the spin is applied to the overall system, wherein a projectile including smoke bodies attains rotational speeds of up to 18,500 rpm after approx. 12 ms upon clearing the muzzle. This high rotational speed generates tangential, radial and axial stresses in the smoke active mass, which may result in the active masses being torn open and sliding away in a radial direction on the free surface of the active masses. Sliding away and disruption of the active mass may then - as was repeatedly observed in practice - result in spontaneous ignition of the smoke active mass andthus in a critical failure of the projectile altogether.
In the prior art it was attempted to mechanically
uncouple the single submunitions with the aid of an air gap between the free surface of the active mass and the lid. Nevertheless enormous strains still occurred. Thus the forces occurring in the steel walls during discharge, e.g. of a smoke body of the prior art, amount to approx.
1000 N/mm2. Due to the principle of uncoupling in accordance with the prior art, involving an air gap between a planar lid and the active mass, compressive strains of about 15 N/mm2 occur on the free surface of the active masses owing to the discharge acceleration. In addition, by the high radial acceleration at approx.
18,500 rpm radial, axial and tangential forces in the range of approx. 15 to 25 N/mm2 are furthermore introduced into the active mass. These strains may, besides the sudden decomposition, result in destruction of the mechanical integrity of the active masses and thus in failures of the ammunition.
In view of all this, it was an object of the present invention to furnish an improved ammunition which is capable of better tolerating the discharge load and the high spin impulse than conventional projectiles.
This object is achieved through a projectile having the characterizing features of claim 1, and a submunition in accordance with claim 13.
The core item of the present invention is a projectile including a projectile shell and submunitions arranged therein on top of each other, wherein the submunitions have a submunition body shell with active mass contained therein, the active mass resting on a bottom, and the submunition body shell being provided with a lid in the direction of discharge, and wherein at least one biasing body is provided between the upper surface of the active mass in the direction of discharge and the lid.
In accordance with the present invention, the free surface of the active mass of each submunition of a projectile is provided with at least one biasing body which applies a certain bias on the active mass.
This artificially generated bias has the effect that the loads acting as a result of the spin impulse may be tolerated without any sliding off and an associated disruption of active mass portions, and the above described problems of prior-art active masses do not occur.
As a biasing body, e.g., simply elastic discs may be used which generate compressive strain by compression.
Here it is advantageous that these elastics discs are instantaneously burnt without releasing toxic gases when the active mass is kindled. Suitable materials are, for example, synthetic foams, rubber foam, rubber or plastic panels of various plastics, natural and synthetic felts, for example polyester felts.
Altogether it is possible with the simple measure in accordance with the present invention, to raise the tolerable stresses in the active mass to 30-35 N/mm2.
Thanks to this measure, destruction of the active masses owing to the high discharge acceleration and the high rotation speed of the projectile do not occur.
The present invention acquires particular importance if the projectiles used are smoke projectiles, the active mass of which is in particular on the basis of red phosphorus.
Preferably the smoke active mass comprises an igniter charge, a preliminary smoke charge, and a main smoke charge, wherein a so-called mixed charge of preliminary lO and main smoke active mass may be arranged between preliminary smoke charge and main smoke charge.
A preferred embodiment of the present invention is that the biasing body at least partly covers the surface of the active mass. Thus the present invention encompasses both full-area covers of the active mass and also, e.g., annular covers, wherein covers on the external zone relative to the longitudinal axis of the active mass are preferred.
In accordance with a preferred embodiment of the present invention, the biasing body may be selected from the group comprising: elastic bodies, in particular disc-shaped bodies; bodies of elastic materials such as synthetic foam, rubber foam, rubber, plastic panels; natural and/or synthetic felts, in particular polyester felts) plate springs including at least one spring, wherein the plate at least partly covers the surface in the direction of discharge of the active mass.
Preferably the biasing body is arranged in a compressed form between the surface in the direction of discharge of the active mass and the lid, so as to apply the appropriate bias on the active mass surface.
In accordance with the present invention it is preferred if the biasing body applies a biasing compressive load of approx. 0.2-20 MPa (N/mm2) on the surface in the direction of discharge of the active mass.
It is moreover preferred if at least 4 submunitions, in particular ones with smoke active masses, are provided inside the projectile shell.
-
It is moreover preferred to inwardly crimp the lid of the individual submunitions, and hereby compress the biasing body between active mass surface and inwardly crimped lid so as to achieve the suitable bias.
A preferred projectile in accordance with the present invention is a smoke projectile, wherein the submunitions comprise a smoke body shell, in particular of steel, with bottom, support tube and lid, wherein the smoke active mass is arranged.
Further advantages and features of the present invention result from the description of an embodiment and from the drawings, wherein: Fig. 1 shows a schematic view in longitudinal section of a prior-art smoke projectile with an air gap between lid and active masse and Fig. 2 shows a schematic view in longitudinal section of a smoke projectile in accordance with the invention, with a biasing body between inwardly crimped lid and active mass surface.
In Fig. 1, a smoke submunition in schematic longitudinal view, which are arranged on top of each other in a smoke projectile, is designated as 1.
The smoke submunition in accordance with Fig. 1 comprises a submunition body shell of steel 2, inside which the active mass 3 is located. The submunition body shell 2 is provided with a lid 4 in the direction of discharge. In the right-hand part of the submunition shown in Fig. 1 there is a venting hole 5 from which the smoke may exit after ignition of the active mass.
In order to uncouple the active mass 3 from the direction of effect of the inertia forces due to the discharge acceleration, in the prior art in accordance with Fig. 1 merely an air gap 6 between the planar lid 4 and the upper surface 7 of the active mass 3 when viewed in the direction of discharge is provided.
The inertia forces generated by the discharge acceleration are thus merely uncoupled from the active mass 3 by the air gap 6, to be distributed on the submunition body shell 2, the bottom 8, and the support tube 9.
In Fig. 2 an exemplary submunition for a projectile according to the invention is shown under 10. Identical reference symbols as in Fig. 1 designate identical components.
In contrast with the prior art in accordance with
Fig. 1, physico-mechanical uncoupling of the active mass of a submunition is achieved not only by means of an air gap between inwardly crimped lid and submunition body arranged above it in the direction of discharge, but additionally by means of a biasing body 12 which, in the exemplary case, has the form of an annular polyester felt formed to have a thickness of approx. 9 mm.
In the exemplary case, the polyester felt constituting a biasing body 12 leaves an air space 13 concentric around the support tube 9, which serves for pressure ignition of the smoke active mass 3.
In the present exemplary case the active mass 3 includes a main smoke not shown in detail in Fig. 2, a mixed charge, and a preliminary smoke which is ignited by an igniter charge via the central support tube 9 which at the same time forms the igniting passage, and then initially ignites the preliminary smoke, which then ignites the mixed charge following its combustion, which in turn ignites the main smoke following its combustion.
Upon arrival in the target area, an ejector charge is initiated with the aid of the primer, which ejector charge on the one hand ignites the smoke body, and expels the smoke body from the projectile shell. Following ignition, the felt disc between lid and igniter charge surface burns away to immediately liberate the venting openings 5 in the lid 4, so that the smoke may escape as intended.
In the embodiment, the active mass 3 includes an igniter charge comprised of: iron(III) oxide 40-60% coated red phosphorus 10-25% uncoated magnesium 5-25% Preliminary smoke: iron(III) oxide 10-30% coated red phosphorus 40-60% - 9 - coated magnesium 5-20% solvent-free dispersion binder 4-10% Mixed charge: preliminary smoke 50% main smoke 50% Main smoke: coated red phosphorus 60- 70% potassium nitrate 8-20% coated magnesium 5-20% solvent-free dispersion binder 3-8% The described active masses are press-processed in a pressing step with a specific compressive pressure of 125 N/mm2 in the order opposite to the direction of discharge: igniter charge, preliminary smoke, mixed charge and main smoke.
After working the smoke charges into the submunition body shell 2 of steel as the active mass 3, the above described polyester felt is inserted, after which an inwardly crimped lid 4 is pressed into the submunition 10. By pressing in the inwardly crimped lid, the polyester felt is compressed from an original thickness of approx. 9 mm to a thickness of 4- 5 mm, whereby a bias of approx. 0.5-0.8 N/mm2 is generated. The tolerable stresses in the active mass 3 are thus raised to approx.
30-35 N/mm2.
The required felt strips are in the exemplary case manufactured by punching from felt panels.
In the exemplary case four submunition bodies 10 are worked into a projectile according to the invention. Due to the fact that the bottom 8 of the submunition body 10 rests on the edge of the submunition located below it, there is an air gap between the inwardly crimped lid 4 and the bottom 8 of the submunition 10 located above it in the direction of discharge, with the result that the submunitions arranged on top of each other in the projectile are uncoupled from each other due to the resulting air gap.
Projectiles having this kind of construction tolerate both the discharge load of up to 2,650 kN and a spin of up to 18,500 rpm.
In the projectile described by way of example, destruction does not occur in the active mass 3. There are moreover no sudden spontaneous ignitions. - 11
