Abstract
In the present invention a helical baffle is provided in a fuze head to pent a direct impact on the detonator by providing an effective cover to all elements of the detonator. This is done by providing a helical structure for protection against, solid objects, the build-up of a large volume of rain and inhibit direct impact of such material upon the detonator.
Claims1
An improved impact sensitive fuze for explosive missiles comprising:
- a truncated conically shaped body having a longitudinal axis and an axial bore;
- said body having a plurality of apertures in its base extending transversely of said axial bore and communicating with said bore;
- means for detonating said missile mounted in said bore;
- and
- barrier means, mounted in said bore intermediate the front end of said bore and said detonating means, adapted to provide an effective cover for said detonating means, thereby preventing axially moving objects from striking said detonating means, while permitting small objects, such as droplets of water, to pass through said barrier means in directions inclined to the longitudinal axis, wherein said barier means is in the form of a twisted cruciform having a twist angle of at least 90.degree..
