Appl. No.:

09/839738

Inventors:

Robert B. Dooley - Canton MA

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

G01L 514

US Classification:

73167, 738656, 738653

Abstract:

The invention features a modified catch tube component capable of performing the function of the conventional catch tube and the conventional MEM simultaneously. The catch tube will also feature a capability to accept modular units of mass for adjusting the available angular momentum (of the spinning catch tube) as well as to incrementally adjust inertial resistance for controlling post-impact translational motion. The safety and performance enhancements of the modified spinner are achieved by the above mentioned integration of the MEM with the catch tube. This invention will eliminate MEM free flight and prevent excessively soft, or excessively hard projectile impacts. Equipment such as rails and wheel sets are used to assure that the motion of the catch tube is constrained to translation and to rotation. The invention contrasts conventional spinners in that the motion of a conventional catch tube is limited to rotation only and the MEM to translation and rotation.

Abstract:

A method and structure for a full-bore artillery projectile fin deployment device comprising a projectile stabilization fin comprising an aperture and a movable pawl; a rod comprising a head portion and a shaft portion terminating with a beveled tip configured for engaging the pawl; a tailboom configured for housing the fin, wherein the tailboom comprises a hollow bore configured for receiving the rod; a pin slotted through the aperture and attached to the tailboom; and a bias member adjacent to the head portion of the rod. The rod is slotted to simultaneously engage a plurality of fins. The tailboom comprises a forward end and a rearward end and a slot configured for permitting the fin to articulate out of the tailboom, and wherein the tailboom connects to a projectile. Additionally, the power source for the device is the naturally occurring launch accelerations.
