Abstract: A projectile propulsion system includes a launch tube, multiphase material, and a pressure barrier member. The launch tube has an interior cavity, the multiphase material disposed therein. The launch tube also has an opening to receive the multiphase material. The pressure barrier member seals the opening while the multiphase material is disposed in the interior cavity of the launch tube so as to allow the launch tube to be pressurized. When the pressure barrier member is broken, a shock wave allows the contents of the interior cavity, such as a projectile, to be expelled from the tube with a high velocity and force.

Abstract: Systems and methods are disclosed relating to a system including a launch tube and a generator connected with the launch tube. The generator uses multiphase materials (MPM) and compressed air to convert kinetic energy of the MPM into electrical energy.

Abstract: A projectile propulsion system includes a launch tube, multiphase material, and a membrane. The launch tube has an interior cavity, the multiphase material disposed therein. The launch tube also has an opening to receive the multiphase material. The membrane seals the opening while the multiphase material is disposed in the interior cavity of the launch tube so as to allow the launch tube to be pressurized. When the membrane is broken, a supersonic wave thrusts the contents of the interior cavity, such as a projectile, outwards with a high velocity and force.
