Abstract
A one-piece wrap around fin for a projectile which includes a main portion, a first end and a second end. The main portion has at least one flap. The first end and the second end cooperate such that the fin is circumferentially mountable around the projectile.
Claims15
A one-piece wrap around fin for a projectile, the one-piece wrap around fin comprising:
- (a) a main portion, the main portion comprising at least one flap;
- (b) a first end;
- and
- (c) a second end, the first end and the second end cooperating such that the fin is circumferentially mountable around the projectile, wherein when the fin is circumferentially mounted around the projectile the at least one flap extends outward from the projectile, the first end comprising a tab and the second end comprising a slot, the slot corresponding to the tab.
A one-piece wrap around fin for an aerodynamically stabilized kinematic infrared countermeasure, the one-piece wrap around fin comprising:
- (a) a main portion, the main portion comprising at least one flap;
- (b) a first end, the first end comprising a tab;
- and
- (c) a second end, the second end comprising a slot, the slot corresponding to the tab, the first end and the second and located on opposite ends of the one-piece wrap around fin, the tab and the slot cooperating such that the one-piece wrap around fin is circumferentially mountable around the countermeasure, when the one-piece wrap around fin is mounted around the countermeasure the at least one flap extends outward from the countermeasure, the one-piece wrap round fin manufactured from spring steel.
A one-piece wrap around fin for an aerodynamically stabilized kinematic infrared countermeasure, the one-piece wrap round fin comprising:
- (a) a main portion, the main portion comprising at least one flap:
- (b) a first end, the first end comprising a tub;
- and
- (c) a second end, the second end comprising a slot, the first end and the second end are located on opposite ends of the one-piece wrap around fin, the tab and the slot cooperating such that the one-piece wrap around fin is circumferentially mountable around the countermeasure, when the one-piece wrap around fin is mounted around the countermeasure the at least one flap extends outward from the countermeasure, the countermeasure comprising flanges, the flanges entrapping the one-piece wrap around fin on the countermeasure, the one-piece wrap around fin manufactured from spring steel, the spring steel containing about 0.69% to about 0.80% carbon, is oil tempered, quenched in oil during manufacture, and has a Rockwell Hardness in a range of about C44 to about C47.
