Claims6
A solid propellant grain comprising a plurality of layers of encapsulated particulate solid fuel and layers of encapsulated particulate solid oxidizer, said fuel and oxidizer being encapsulated within their respective layers by a matrix comprising polytetrafluoroethylene and a polymeric adhesive, adjacent layers in said grain being bonded together at their confronting surfaces by a polymeric adhesive, and the layers in said grain being so disposed that a layer of oxidizer alternates with a layer of fuel.
A solid propellant grain in essentially tubular form comprising a plurality of layers of encapsulated particulate solid fuel and layers of encapsulated particulate solid oxidizer, said fuel and oxidizer being encapsulated within their respective layers by a matrix comprising polytetrafluoroethylene and a polymeric adhesive, adjacent layers in said grain being bonded together at their confronting surfaces by a polymeric adhesive, and the layers in said grain being so disposed that a layer of oxidizer alternates with a layer of fuel.
