Armor-Penetrating Ammunition Assembly With Aluminum Protective Cap

View page
US Patent:
47577665, Jul 19, 1988
Filed:
Jan 28, 1987
Appl. No.:
7/007851
Inventors:
Paul D. Ruffle - Edina MN
Randall L. Schiestl - Brooklyn Park MN
Robert L. Bonde - Minneapolis MN
Assignee:
Honeywell Inc. - Minneapolis MN
International Classification:
F42B 1316
US Classification:
102521
Abstract:
An armor-penetrating ammunition assembly is provided with a multiple segment aluminum protective cap 26. The cap 26 is provided with a plurality of stiffening ribs 34, 34', 35, 35', and torque resisting tabs 40, 40' which rest in one of the grooves 37, 37' defined by the ribs 34, 34'. Additional stiffening is provided by rolled stiffening portions 36, 36' at the trailing end 32 of cap 28 and by longitudinal ribs 38, 38' at the longitudinal edges of each segment 28, 28' of the cap 26. Attachment structure is provided for forming a fixed interconnection between each segment 28, 28' of the cap 26 and a corresponding portion 19, 19' of the sabot 18. Thus, each segment 28, 28' of the cap 26 remains attached to a corresponding sabot portion 19, 19' as each portion 19, 19' of the sabot 18 separates from the penetrator 12 at muzzle exit without disturbing the flight of the penetrator 12.

Fin Stabilized Armor-Penetrating Tracer Projectile And Method Of Manufacturing Same

US Patent:
47320869, Mar 22, 1988
Filed:
Jan 27, 1987
Appl. No.:
7/006859
Inventors:
Randall L. Schiestl - Brooklyn Park MN
Paul D. Ruffle - Edina MN
Assignee:
Honeywell Inc. - Minneapolis MN
International Classification:
F42B 1116
US Classification:
102513
Abstract:
A method of securing a tracer cup 26 and fin segments 32, 33 to armor piercing penetrator 21. The penetrator 21 is fabricated of tungsten, or steel, with fin segments 32, 33 and tracer cup 26 being fabricated of steel. The tracer cup 26 contains a pyrotechnic tracer mix 27. The mounting flange 28 of tracer cup 26 is placed over a second boss 24 projecting rearwardly from a first boss 23 at the aft end of the cylindrical body of penetrator 21. A cylindrical sleeve 30 is press fit over the tracer cup 26 and first boss 23, and pre-fabricated fin segments 32, 33 are positioned on the sleeve 30. The fin segments 32, 33, cylindrical sleeve 30, and mounting flange 28 of tracer cup 26 are laser welded to each other and to the first boss 23 of penetrator 20 in one step. Increased laser power is applied to weld a fin segment 32 or 33 to the sleeve 30 and the sleeve 30 to the first boss 23 of the penetrator 20 and the sleeve 30 to the mounting flange 28 of tracer cup 26 compared with the magnitude of the laser power applied to weld a fin vane assembly 32 or 33 to the sleeve 30.

Armor-Penetrating Ammunition Assembly With Molded Protective Cap

View page
US Patent:
47198605, Jan 19, 1988
Filed:
Jan 28, 1987
Appl. No.:
7/007852
Inventors:
Paul D. Ruffle - Edina MN
Randall L. Schiestl - Brooklyn Park MN
Robert L. Bonde - Minneapolis MN
Assignee:
Honeywell Inc. - Minneapolis MN
International Classification:
F42B 1316
US Classification:
102521
Abstract:
An armor-penetrating projectile assembly 10 is provided with a molded protective cap 28. The cap 28, which is preferably molded from Nylon 6/6, is provided with a plurality of longitudinal stress grooves 34 formed in the interior surface of the cap 28 for aiding cap break-up as the projectile assembly 10 exits the muzzle of a cannon, and with an integral centering band 32 for ensuring a desired fit of the projectile assembly 10 inbore and, to control the angular velocity of the cap 28 about its axis of symmetry 46 for better separation after being fired. The cap 28 is fastened to the sabot 18 of the projectile assembly 10 by means of a grooved extension 36 on the sabot 18 within which a plurality of ramped projections 38 of cap 28 are received. The ramped projections 38 are molded into the inner surface of the cap 28 aft of each window 40. The windows 40 and ramped projections 38 permit the cap 28 to be readily separated from the mold in which cap 28 is formed using a pull mold even when cap 18 is formed of a high strength non-resilient material such as Nylon 6/6.
