Publication number: 20050188891Abstract: A discarded propelling cage sabot for a sub-caliber projectile is provided. The sabot includes a plurality of propelling cage sabot sections arranged side-by-side in a circumferential direction and separated by separating joints, each of the propelling cage sabot sections having a pressure flange having a groove-shaped recess, and a frustum-shaped propelling cage sabot region which is positioned rearward in the direction of flight relative to the pressure flange. The sabot also includes a plurality of sealing band segments that are arranged side-by-side in the circumferential direction and are separated by separating joints, each of the sealing band segments corresponding to one of the propelling cage sabot sections.Type: ApplicationFiled: May 5, 2004Publication date: September 1, 2005Inventors: Thomas Heitmann, Michael Imdahl, Martin Berg, Stefan Keil

Patent number: 6769364Abstract: A full-caliber projectile having a cylindrical guide region (5) and an ogival projectile tip (7). To improve the stabilization of the projectile (1) inside a gun barrel (2) in a simple manner, and therefore improve the intermediate ballistics and hit accuracy over those of comparable projectiles, a guide ring (8), which is segmented in the circumferential direction, and whose outer diameter is smaller than the inner diameter of a gun barrel (2) of the same caliber, is secured to the projectile tip (7) such that the radially spaced guide-ring segments (9) detach from the projectile (1) in the gun barrel (2) when a predetermined firing acceleration occurs in the gun barrel, and the segments (9) are pushed toward the projectile (1), axially relative to the cylindrical guide region (5), by dynamic pressure until they rest against the inside wall (18) of the gun barrel (2) and against the projectile (1).Type: GrantFiled: November 25, 2002Date of Patent: August 3, 2004Assignee: Rheinmetall W & M GmbHInventors: Jürgen Kolodzey, Thomas Heitmann, Michael Imdahl, Michael Vagedes

Patent number: 6758435Abstract: A missile includes a missile body and a guide assembly mounted on the missile body. The guide assembly has a plurality of pivots and a plurality of vanes mounted on respective pivots for a swinging motion between a folded position of rest and a deployed flight position. The vanes are arranged for free pivotal motion during flight in response to forces acting thereon to determine the flight position. In the folded position of each vane, its center of gravity is situated at a greater distance from the longitudinal axis of the missile body than the pivotal axis of the respective vanes. Abutments limit the flight position of the vanes to a maximum angle between the length dimension of the vanes and the longitudinal axis of the missile body. The maximum angle is greater than 90°.Type: GrantFiled: August 23, 2002Date of Patent: July 6, 2004Assignee: Rheinmetall W & M GmbHInventors: Torsten Niemeyer, Manfred Dieter Schwies, Uwe Naderhoff, Thomas Heitman, Michael Imdahl, Rudolf Rombach
