The patent describes a fuze system designed for attachment to a munition body, featuring a power generator that harnesses energy from the surrounding airstream to power the fuze. This generator is uniquely configured to rotate relative to the munition’s foremost section while maintaining a compact profile that does not exceed the outer diameter of the body.

Claim 1

1 . A fuze system for attaching to a munition body, the fuze system comprising: a body comprising a foremost section; a fuze located in the body; and a power generator, attached to the body, for generating electrical power and providing it to the fuze system, the power generator configured to generate electrical power by interacting with an airstream around the fuze system, wherein at least a part of the power generator is located behind the foremost section, the at least a part of the power generator being arranged to rotate relative to the foremost section of the body, wherein the power generator comprises one or more recesses, channels, and/or grooves extending into or below a surrounding surface and configured to interact with the airstream around the body, and wherein an outermost diameter of the power generator, including the one or more recesses, channels, and/or grooves, does not extend beyond an outermost diameter of the body. a body comprising a foremost section; a fuze located in the body; and a power generator, attached to the body, for generating electrical power and providing it to the fuze system, the power generator configured to generate electrical power by interacting with an airstream around the fuze system, wherein at least a part of the power generator is located behind the foremost section, the at least a part of the power generator being arranged to rotate relative to the foremost section of the body, wherein the power generator comprises one or more recesses, channels, and/or grooves extending into or below a surrounding surface and configured to interact with the airstream around the body, and wherein an outermost diameter of the power generator, including the one or more recesses, channels, and/or grooves, does not extend beyond an outermost diameter of the body.
