Abstract
A radome wall structure includes one or more laminate plies, a first syntactic foam layer on one side of the one or more laminate plies, and a second syntactic foam layer on the other side of the one or more laminate plies. One or more laminate plies are between a third outer syntactic foam layer and the first syntactic foam layer and one or more laminate plies are between a fourth inner syntactic foam layer and the second syntactic foam layer. An interior matching layer is adhered to the fourth inner syntactic foam layer.
Claims19
A radome wall structure comprising:
- one or more laminate plies;
- a first syntactic foam layer on one side of the one or more laminate plies;
- a second syntactic foam layer on the other side of the one or more laminate plies;
- a third outer syntactic foam layer;
- one or more laminate plies between the third outer syntactic foam layer and the first syntactic foam layer;
- a fourth inner syntactic foam layer;
- one or more laminate plies between the fourth inner syntactic foam layer and the second syntactic foam layer;
- and
- an interior matching layer on the fourth inner syntactic foam layer.
A radome wall structure comprising:
- a core including:
- one or more laminate plies sandwiched between first and second syntactic foam layers,
- a laminate layer including one or more plies on the first syntactic foam layer, and
- a laminate layer including one or more plies on the second syntactic foam layer;
- an outer syntactic foam matching layer adjacent one side of the core;
- an inner syntactic foam matching layer adjacent the opposite side of the core;
- and
- an interior matching layer adjacent the inner syntactic foam matching layer.
A radome wall structure comprising:
- a ½ wavelength thickness core including layers of syntactic foam and laminate materials;
- inner and outer ¼ wavelength thickness syntactic foam matching layers;
- and
- a ¼ wavelength thickness interior matching layer.
