4 Claims, 1 Drawing Figure Patented July 18, 1972 INVENTCRS GUNNAR GILJARHUS HANS VIEN TTORNEYS PROJECTILE WITH MULTIPLE EFFECT The present invention relates to projectiles having multiple eflect for use in ammunition to be fired from aircraft guns, anti-aircraft guns and ground artillery as well as for navy purposes, of small caliber, for instance up to 40 mm. The basic principle of the invention may, however, also be adapted to greater calibers.
Incendiary projectiles are known being charged with incendiary material in both of the main components of the grenade, that is the top portion and the body portion. An incendiary projectile having such a construction, however, has a strongly limited use in that it may only subjected to relatively small G- values. Consequently ammunition of this type and when used in modern weapons with high initial velocity and high gas pressures (P will be self-igniting in a gun because of set back of the incendiary charge of the top portion against the incendiary charge of the body portion. Such untimely igniting action is a critical fault in the ammunition.
Furthermore, the commonly known types of incendiary grenades have the drawback that, upon impact with thinwalled objects, such as the more vulnerable parts of an aircraft-wing, the grenade body does not disintegrate into fragments but will penetrate straight through the object in its initial form with minimal damaging effect.
It is known to attempt eliminau'on of this drawback by positioning a high explosive bursting charge inside the nose portion of the grenade on top of the incendiary charge. By impact the grenade will thus in a thin-walled object, such as parts of an aircraft, be subjected to fragmentation and the body fragments together with the incendiary charge will be sprayed into the target with great damaging effect. This known principle is based on the condition that the grenade is provided with a fuse, the initial and booster charge of which will bring about the detonation of the explosive charge of the grenade.
it is furthermore known for heavier and more compact targets, for instance light armored vehicles, fuel tanks, ships hulls and the like, to use plain armor piercing projectiles or armor incendiary projectiles. The main component in such a projectile type is a compact hardened steel core having great penetrating ability through steel and armor plates. However, this type of projectile has also substantial drawbacks, for instance that the armor core usually will not disintegrate on penetration and one therefore fails to achieve the damaging efi'ect of fragments inside the target. Furthermore, when using such projectiles the armor core will during penetration of the target peel off the incendiary charge, the top portion and the like. The substantial portion of the incendiary effect will thus take place on the front side (externally) of the target and not penetrate into same as was desired. Additionally such a projectile will at the moment of impact on a slanting target, with impact angles smaller than approx. 30, skid off and consequently have no effect at all.
It is thus a main object of this invention to make available a projectile which as such forms a combination of several new principles in order to achieve various forms of damaging effects in a variety of targets, such as incendiary eflect, fragment effect and penetrating effect. A further object of the invention is to provide a projectile having multiple efi'ects and which eliminates all of the above desired drawbacks.
This is achieved with a projectile having multiple efiects, comprising elements for incendiary effect and fragmentary effect as well as great penetrating capacity and which at the same time may be provided with per se known tracing elements and self-destruction elements, a characteristic feature of the invention being that the fragmentary effect is achieved by means of an explosive charge positioned behind a first and second incendiary charge, said explosive charge being detonated without any fuse means. Another feature of the invention resides in that the first incendiary charge portion positioned in the top portion is supported by a disc having left hand threads and a central bore through which the secondary incendiary charge is ignited. This supporting disc should be designed to stand very high G-values.
Particularly the feature comprising the explosive charge being detonated without any fuse means is obviously advantageous because the projectile or grenade may be supplied or filled with a considerably greater quantity of incendiary charge which means that it is not necessary to reserve any space for fuse means and booster charge. In addition to the desired fragmentary efi'ect, a maximum of incendiary effect is thus achieved. It is further of substantial economic importance that this type of grenade may be detonated without any fuse means because the fuse means as such usually represents nearly 50 percent of the total costs of the grenade for small caliber ammunition.
in the drawing is shown an embodiment of a projectile according to the invention, in longitudinal section.
With reference to the drawing a projectile according to the invention comprises a top portion 1 and projectile body portion 2, each of said main portions containing an incendiary charge 3 and 4 respectively. The projectile body portion 2 furthermore comprises internally an explosive charge 5, a socalled self-destructing means 6 with associated detonating means 7 and a tracer means 8 with associated igniting means 9. The projectile is further completed rearwardly by means of a sealing disc 11 and a steel ring 12, it being understood that the tracer means andself-destructing means for certain purposes may be omitted.
The first incendiary charge 3 comprised in the top portion 1 is maintained in position during firing of the projectile by a supporting disc 13 which by means of left hand threads has been screwed into the top portion 1. The supporting disc 13 has a central bore or opening 14 through which the secondary incendiary charge 4 is ignited. The incendiary charge 3 contained in the top portion 1 has a rearwardly supporting surface formed with a bridge construction 15 for the purpose of withstanding the shearing forces caused by setback of the charge 3 and thus prevents untimely ignition. The supporting disc 13 is designed and calculated to stand very high G-values of at least 150,000 without untimely ignition of the incendiary charge.
This incendiary charge is ignited by impact on a target, the ignition being initiated through friction, shock and heat through distortion of the nose by the impact.
The explosive charge 5 positioned in the body portion 2 directly beneath the second incendiary charge 4 is detonated without any fuse means but by means of the second incendiary charge 4 and this results in the said advantages comprising larger space for filling with incendiary charges inside the projectile besides substantially lower production costs. Furthermore, the detonation of the explosive charge 5 is delayed through the incendiary charges in such a way that the projectile also is provided with a greater piercing effect compared with explosive grenades by an appropriate choice of materials in the top portion 1 and the body portion 2 and by the fact that the total kinetic energy of the projectile is utilized contrary to the explosive grenades where the energy of the explosive is used.
The elements for tracing and self-destruction arranged in the projectile are per se known and should not require further explanation or description in this connection.
The above mentioned drawbacks in known projectiles such as armor piercing and incendiary projectiles, particularly the fact that same are not sufficiently disintegrated to cause damaging effects by fragments inside the target and that the incendiary charge, the top portion and the like are peeled off by the impact, have been eliminated in the projectile according to the invention. This is due to the form given to the top portion and projectile body in cooperation with the fact that a suitable choice of material for the same parts has proved by numerous tests to give the very surprising and advantageous result that the projectile will straighten itself and break through the target surface by impact on sloping targets through friction and braking effect in the top portion against the target surface. Simultaneously the incendiary charge above the explosive charge will provide a delay in thedetonation of the latter in such a way that the total kinetic energy of the projectile is utilized for the piercing work before the detonation and the disintegration of the projectile body. Furthermore, the projectile in the final phase of penetrating a steel plate will also partly disintegrate into fragments which will simultaneously blow or stamp out a hole having twice the size of the respective caliber. In addition to the grenade body fragments even fragments from the steel plate will penetrate into the target and cause great damaging effect. Because of the already mentioned piercing eflect, the incendiary charge will not be peeled off on the front side of the target, but on the contrary will be sprayed into same together with the fragments and having full incendiary effect.
The above described effects have been proved during a large number of tests with the projectile according to the invention and thus are not only theoretical results.
