US Patent:

7849797, Dec 14, 2010

Filed:

Oct 31, 2008

Appl. No.:

12/262457

Inventors:

Chris E. Geswender - Green Valley AZ, US
Stephen E. Bennett - Tucson AZ, US
Cesar Sanchez - Tucson AZ, US
Matthew A. Zamora - Tucson AZ, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

F42C 13/04

US Classification:

102211, 342 68

Abstract:

A projectile fuze sends a signal having encoded telemetry data. The telemetry data may be encoded by modulating an aspect or characteristic of the signal, such as frequency modulation of the signal. The fuze may receive and interpret reflections in order to determine proximity to a target or other object, such as by functioning as a height of burst sensor. The signal may include a series of random or seemingly random pulses (a keyed pattern of pulses), such as pulses in amplitude of the signal. The fuze includes a pair of transceivers for sending signals of different frequencies through an antenna, and for receiving signals through the antenna. The transceivers are configured such that one or the other is used at any one time when telemetry data is sent, with telemetry being encoded by changes in frequencies.

International Classification:

F42B 15/01

US Classification:

244 324, 244 31, 244 325

Abstract:

A fuze guidance system is configurable by an end user, allowing the end user to select between different configurations of canards of the system. The different configurations of canards may include canards with different surface areas, optimized for providing appropriate control with different sizes of munitions. The different configurations may be accomplished by having canards with separable portions which may be broken off or otherwise removed by the end user, to reduce canard surface area and/or span. Alternatively the fuze guidance system may come in a kit with multiple sets of canards having different sizes or otherwise having different configurations for providing different aerodynamic characteristics. The end user may select a canard set based on the munition size or type that the fuze guidance system is to be used with.

Assignee:

Raytheon Company - Waltham MA

International Classification:

F42B 15/01

US Classification:

244 324, 102385

Abstract:

A multi-caliber fuze kit includes a fuze housing configured for coupling with multiple projectiles. One or more canards are moveably coupled with the fuze housing. The one or more canards are adjustable between two or more canard configurations. In a first canard configuration, the one or more canards are at a first canard angle relative to a bore sight of the fuze housing, and the first canard angle is configured for use with a first projectile. In a second canard configuration, the one or more canards are at a second canard angle relative to the bore sight of the fuze housing, and the second canard angle is configured for use with a second projectile. The first and second canard angles are different. In another example, in the first canard configuration the one or more canards include a first canard shape configured to provide a first specified trajectory with the first projectile. In the second canard configuration the one or more canards include a second canard shape configured to provide a second specified trajectory with the second projectile.

Assignee:

Raytheon Company - Waltham MA

International Classification:

F16J 15/02

US Classification:

277312, 277630, 277917

Abstract:

Methods and apparatus for a seal according to various aspects of the present invention include a seal operating in conjunction with a housing and a removable cover. A portion of the seal is attached to the housing and another portion of the seal is attached to the removable cover to enclose a joint between the housing and the removable cover. A cutter cuts the seal, which allows the removable cover to be removed.

International Classification:

F42C 11/00

US Classification:

102206

Abstract:

A smart fuze system includes a radome used to hold a replaceable smart fuze module in place. An internally-threaded collar screws onto threads on the main body of the smart fuze system. Pressure from the radome presses the smart fuze module against electrical connections in the main body. The smart fuze module may thereby be held in place without potting material, allowing different types of fuzes to be swapped into place. The different types of fuzes may include a type that communicates height of burst (HOB) information a type that communicates telemetry, and a type that communicates both HOB and telemetry information.
