A projectile propulsion system comprises a housing defining a chamber, a propulsive charge including a propulsive charge material loadable into the chamber, a projectile loadable into the chamber proximate to the propulsive charge material, an electric pulse discharge subsystem that provides an electric pulse having a specified pulse amperage for a specified pulse period, a current delivery subsystem electrically connecting the electric pulse discharge subsystem to the chamber to deliver the electric pulse to the propulsive charge material, wherein the specified pulse amperage and the specified pulse period are sufficient to cause at least a portion of the propulsive charge material to generate a propulsive force that is at least partially directed onto the projectile to drive the projectile out of the chamber, and a barrel in fluid communication with the chamber configured to receive the projectile as it is driven from the chamber.
A Lynchpin structure may be combined with one or more additional Lynchpin structures to form a compound Lynchpin propulsion structure. Each Lynchpin structure may include six pentangular areas, and one or more of the pentangular areas may include a propulsion device. The propulsion may be used to propel the compound Lynchpin propulsion structure through or over various media, such as through air, across ground, on or underwater, or through or over other media. The propulsion may include avionic propulsion, ground propulsion, hydrodynamic propulsion, or other types of propulsion. A single type of propulsion device may be used within one or more of the pentangular areas, or diverse types of propulsion may be used to provide various navigational performance or multi-mode operation. Each propulsion device may also include a device to direct the propulsion, such as a single or multi-axis gimble or adjustable aerodynamic control surface.

Collapsible structures may be formed from planar solids. The structures may be comprised of multiple planar objects hingedly connected, where each planar object may include magnetic materials (e.g., magnets, ferromagnetic metals) or electromagnetic materials. Using the magnetic or electromagnetic materials, the connected planar objects may be arranged as a single planar object with multiple layers, or may be arranged as a three-dimensional (3-D) object, where the magnetic or electromagnetic materials may be used to retain the formed 3-D object shape. Application of a current to the electromagnetic materials may cause the collapsible structure to form the 3-D object, and removal of the electric current may cause the collapsible structure to revert to a single planar object. Multiple structures may be combined to form larger structures.
