Abstract
In combination with a plastic fuze radome, a structure for protecting the ternal electronic components housed within said radomes during flight, said structure being a strap-on metal cap designed to slip on or over the ogive of the radome of a fuze. This metal cap is a metal cone having two open windows. The antenna of the fuze electronics is permitted to radiate through the windows while being protected from rain damage by the large umbrella at the top over the plastic nose cone, and from heat flux into electronic components by the large metal band at the bottom. Mechanical ablation of the tip is prevented by the cone of metal acting as a heat sink and as a shield against the wind-stream stagnation pressure. Triboelectric charging is prevented by two conductive straps down the side of the structure, and by a grounding electrical connection.
