Abstract: The actuator system comprises an actuator which includes a cylinder having a first end adapted to receive one or more gas generators and a second end having an opening therethrough. A piston having first and second ends defining the length thereof is movably mounted in the cylinder, dividing the cylinder into first and second variable volume chambers. The piston includes a piston rod attached thereto which extends out through the opening of the second end of the cylinder. An accumulator is coupled by a first passage system to the second variable volume chamber at substantially the second end of the cylinder. A first sequencing system provides for the charging of the accumulator and second chamber after a portion of the stroke. As the piston continues, the gas in the second chamber compresses, building up pressure and slowing the piston down.

Abstract: To brake a sabot accelerated in a launcher of a recoiless rifle tube a mandrel shaped braking sleeve is disposed in the tube and an intermediate space is provided between a tapered surface of the mandrel and the tube into which the material of the front edge of the sabot expanded. In this way when the sabot is accelerated against the mandrel, its front edge slides along the tapered surface, radially outwardly into the intermediate space. This functions to deform and positively stop the movement of the sabot before it leaves the tube.

Abstract: A lightweight, portable, electromagnetic railgun. The invention features a conventional railgun coupled to a magnetic flux compression generator (MFCG) section and an injector section. The conventional railgun has two parallel metallic rails (13,15) with a bullet (25) slidably positioned between them. The bullet is rapidly projected between the rails toward a chosen target when a current flows between the rails (and through the bullet). The MFCG section provides a source of high current to the rails. The MFCG section has a piston (73) which moves between two energized bars (51,53). A magnetic field is created by current flowing in a circuit through the piston, (73) the bars (51,53) and the bullet (25). The associated magnetic flux is rapidly compressed as the piston moves between the bars. Compression of the magnetic flux produces a large current pulse which is coupled to the rails (13,15) to propel the bullet (25).

The upper hull provides the necessary buoyancy to support the vessel with the other hull or hulls flooded with sea water and/or other liquids.

Abstract: An improved sail for sailboards, small sailboats or the like having an efficient airfoil horizontal cross-section. The sail is formed from a sail panel which is wrapped around the mast and extends co-extensively aft away from the mast. An inflatable bag having a sleeve along one side is positioned within the sail panels with the sleeve over the mast. The sleeve is a narrow panel which wraps around the mast inside the sail and has edges substantially parallel to the mast which extend aft along the inside of the sail. The forward edge of the inflatable bag extends between the sleeve panel edges and is secured thereto such that the forward edge of the bag is pressed firmly against the mast when the bag is inflated. This arrangement prevents concave regions from forming immediately behind the mast when the sail is in use, which adversely affect sail performance.
