DE102005039900A1 - Far-reaching full caliber bullet - Google Patents

Abstract

A long range large caliber tank shell (1) comprises a cylindrical body (2) with a primary section (11), a secondary section (12) at the front, a spike shaped tip (7), and a contact surface (8). The rear has a guide member. The outer diameter of the contact surface is smaller than the shell caliber.

Description

The The invention relates to a far-reaching, verschiessbares from a smooth tube Full caliber projectile.

requirements as possible great Payload volume, stable flight behavior over a large speed range, short flight time and high target speed with simultaneous compliance provide the given by the weapon system interface dimensions on anti-tank missiles for size Distances are a problem that usually compromise leads.

In front all due to the required payload volume are blasting projectiles preferably designed as full caliber bullets. However, this arises the problem, a high level of accuracy and a low To reconcile speed loss. Projectiles that out Smooth-tube guns are fired, requiring special constructive activities for a stable flight behavior and a small compensation swirl for compensation of inevitable manufacturing deviations.

to Stabilization of full caliber bullets for smoothbore guns are in practice two stabilization principles known, the wing stabilization by rigid or foldable tail and the shape stabilization by a butt edge with attached spike.

bullets, which are designed for low speed drop point usually an ogival tip contour on. These projectiles react but aufgunr big buoyancy forces and low stability measure across from Disorders.

A full-caliber projectile with a cylindrical guide area and an ogive-shaped projectile nose is the DE 101 57 563 A1 removable. In the DE 103 12 717 A1 It is further stated that this projectile outer shape causes a relatively low velocity drop of the projectile, so that for full caliber tank ammunition, since they have the greatest possible combat distances, this ogival bullet external geometry is used. It is further stated that this geometry is unfavorable for low combat distances in such wing-stabilized full-caliber projectiles with fold-out or swing-out tail wings. Therefore, it is proposed to provide a projectile with a hood-shaped adapter part, which has an outer contour, which is optimally designed to combat targets of short combat distance. On this adapter part is located on the front side a fastening device to which an ogival projectile nose is placed, if the projectile targets large combat distances are to be achieved.

Furthermore, wing stabilized practice bullets with a substantially identical caliber bullet casing and a peg-shaped bullet tip of the DE 198 34 395 C2 known. Such spikes significantly reduce the flow resistance, which is very important at high speeds of a projectile.

wing Stabilized Full caliber bullets need for one sufficient effectiveness either a folding mechanism or a rigid one Tail with a relatively large Distance to the actual projectile body. The disadvantage is However, that rigid tail units by the necessary distance available limit usable space while folding tail while the unfolding process has only low aerodynamic stability, so while this phase acting disturbances lead to significant flight path deviations.

Stabilized form Full caliber ammunition has a relatively high velocity drop on. The aerodynamic stability decreases with decreasing speed. The one by the spike Covered area usually stands for the payload to be transported not available.

Of the Invention is based on the object, designed as a full caliber projectile fin-stabilized Panzergeschoß the aforementioned type indicate which of a given payload volume with sufficient Accuracy and one possible huge Final speed at distances> 2500 m can transport.

These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.

The invention is based essentially on the idea to connect the three aforementioned structural elements shape stabilization, wing stabilization and ogival tip contour with each other. A spike with a sub-caliber impact surface ensures the necessary stability in the first flight phase. The sub-caliber impact surface reduces the velocity drop of previously known full-caliber solutions. The subsequent ogival tip area ensures sufficient payload volume and low loss of speed, and a folding mechanism ensures aerodynamic stability even at smaller projectile speeds.

To becomes the outer diameter the impact surface clearly chosen smaller, as the bullet caliber and thus the speed drop caused by the impact surface across from known comparable floors is substantially reduced, and Although such that one for the projectile stability necessary for the unfolding of the folding tail unit if possible low flow resistance is reached. In this case, the lateral surface of the cylindrical projectile body is within a second portion selected such that they are up to the outer edge the impact surface one constantly decreasing, preferably ogival, course has.

advantageously, owns the projectile according to the invention opposite known bullets reduced speed drop also one larger aerodynamic stability as the latter.

alternative to the ogival outer geometry of the second portion of the lateral surface of the projectile body can also be used a conically shaped external geometry, although calculated with an increase in flow resistance must become.

Further Details and advantages of the invention will become apparent from the following explained with reference to a figure Embodiment.

In the figure is with 1 an inventive tank projectile denotes, which has a substantially cylindrical projectile body 2 for receiving a payload, not shown, for example, explosives includes. At the back end 3 of the projectile body 2 closes a Leitwerksschaft 4 with a folding tail 5 at. In this case, the wings are located in the embodiment shown in the figure 5 ' the folding tail unit 5 already in its unfolded position.

To the front end 6 of the projectile body 2 closes a sub-caliber, spike-shaped bullet point 7 on her bullet body 2 facing side over a perpendicular to the longitudinal axis 100 of the projectile 1 extending impact surface 8th with the lateral surface 9 of the projectile body 2 is connected and the projectile tip side a known per se annular thickening 10 for improving the flow separation.

The lateral surface 9 of the projectile body 2 includes, in the direction of the longitudinal axis 100 of the projectile 1 seen, two subareas 11 and 12 , In this case, the first, relatively long portion 11 the lateral surface 9 a substantially same caliber outer diameter D0, while the front side subsequent smaller second portion 12 that is up to the abutment area 8th extends, according to the invention has an approximately ogival outer contour, so that the diameter D1 of the outer edge of the abutment surface 8th smaller than the bullet caliber D0.
