  • Patent number: 6892646
    Abstract: A guidance electronics unit is provided for an explosively-launched vehicle, e.g., a projectile or missile, comprising a plurality of circuit card assemblies, each circuit card assembly containing a plurality of electronic components and interconnections, each circuit card assembly maintained in a housing and spaced apart. All spaces surrounding each circuit card assembly are filled with a granular material to provide support for each circuit card assembly during explosive launch. Further, a method for supporting circuit card assemblies in the guidance electronics unit is provided. The problem of enabling guidance electronics to survive the large loads encountered during an explosive launch out of a gun, such as a howitzer, or missile launch tube is thereby solved.
