A control surface system is particularly well suited to provide improved control for undersea vehicles having integrated motor propulsors (IMP). The control surface system is deployable beyond lateral peripheral dimensions of the IMP and undersea vehicle. A plurality of arc-shaped control elements is disposed in a stowed position in an annular intake recess inside of an annular duct on the undersea vehicle. Struts connect each of the control elements to the annular duct. A deployment device rotates each of the control elements and the struts radially outwardly beyond lateral peripheral dimensions of the vehicle to a fully deployed position. A latching mechanism selectively engages and disengages the struts to hold the control elements in the stowed position and the fully deployed position, respectively. Launch tubes sized for the undersea vehicles can launch undersea vehicles provided with control surface system.

A launch assembly having an elastomeric tube for launching a device is disclosed. To launch the device an outboard end of the tube is movable outwardly along the length of a housing by an extending device, while the inboard end of the tube is restrained by a release mechanism and remains stationary. Thus, as the outboard end moves and the inboard end remains stationary, the elastomeric tube elongates. The tube may be elongated a predetermined amount, at which time the inboard end of the tube is released by the release mechanism. Releasing the inboard end allows it to travel toward the now stationary outboard end with a sufficient velocity to launch the device. The amount of elongation of the tube is related to the amount of possible launch energy. Thus, greater elongation of the tube provides a greater launch velocity, while shorter elongation provides a reduced launch velocity, as desired.

A synthetic muscle comprises an outer layer having an interior filled with a proton containing electrolyte. A first electrode extends into the interior, and a second electrode extends through the interior. The second electrode is attached to the outer layer at two locations. An ion selective microporous membrane extends through the interior along the length of the second electrode and is also attached to the out layer at the two locations. The ion selective membrane is also attached to the second electrode at a plurality of points along its length, defining a plurality of pockets of the ion selective membrane. The ion elective membrane is generally disposed between the two electrodes. The two electrodes are in communication through a power source. Using the power source, an electroosmotic flow is established across the ion exchange membrane from the first electrode to the second electrode, inflating the pockets and constricting the outer layer.

An underwater supercavitating projectile includes means to form ripples on its surrounding cavity so as to provide well-defined disturbances of the cavity boundary. As the ripples move aft of the supercavitating projectile and into the wake behind the advancing projectile, the ripples detach to form a pattern of vapor bubbles in the wake that are distinct in both size and regularity from the typical vapor bubbles formed as the cavity collapses behind the advecting projectile. Sensors record the track of the projectile along its path based on the distinct acoustic signature of the vapor bubbles. Combined with the acoustic echo from a target, the relative distance of the projectile to the target can be determined using methods known in the art. Multiple projectile trajectories are used to increase the ability to resolve the target by adjusting the aiming of the projectiles to reduce the relative distance.

A high velocity acoustic signal producing underwater shotgun system for dispersing a plurality of relatively small supercavitating projectiles over a wide spatial field at long range using the dynamics of cavity collapse for better target localization in underwater mine clearance. A typical supercavitating projectile design is enhanced to produce a two-staged projectile in order to accomplish this innovation. The first stage of the two stage design allows for the long range firing underwater typical of a supercavitating projectile while the second stage permits the coverage of a wide area with a plurality of small supercavitating projectiles just as the first stage projectile reaches its fixed range. A distinctive feature of the radiated noise from a supercavitating projectile contacting a solid object is used in conjunction with the two stage projectile design to provide a system for underwater mine clearance verification. The distinctive noise signal may also be used in conjunction with an underwater targeting system to help identify, localize and track targets as well.

An apparatus that produces a gaseous vapor baffle that isolates an undersea sonar system from acoustic noise. The apparatus allows for craft carrying undersea sonar systems to travel at relatively high speeds while substantially isolating the undersea sonar systems from acoustic noise interference produced by propulsion systems, hull appendages, waves and bubbles. The apparatus has a support strut that has one end that is joined or attached to the hull of a craft. A sonar pod is attached to the other end of the support strut. The support strut has a ventilation duct and a plurality of ventilation ports. A cavitator is attached to the support strut and produces a sheet cavity as the craft travels in the water. Pressurized air or other gases are injected into the ventilation duct which then exit through the ventilation ports and into the sheet cavity. The pressurized air or gas exiting the ventilation ports expands the sheet cavity to form a gaseous vapor baffle that isolates the sonar pod from acoustic noise.

A muzzle break for a gun comprising a baffle, a series of slots in the housing of the muzzle break in which the slots exhaust gas of a pressure wave deflected by the baffle during firing of the gun. A membrane seals the slots for underwater use and is separable by the deflected exhaust gas. Another membrane seals a sabot separation chamber of the muzzle break adjacent to the baffle and in a projectile path from the baffle. The membrane for the separation chamber is detachable by a projectile fired from the gun.

A system for clearing mines and other obstacles is provided. The system mountable to a vehicle which can operate in water and on land, includes a sonar targeting system and an underwater gun system. The underwater gun system is directed by readings from the sonar targeting system and fires underwater munitions to destroy detected mines and obstacles. The pod containing the sonar targeting system and the pod containing the underwater gun system are movable to target in multiple directions with each of the pods deployed at an end of a respective deployment arm.

A sonar system includes a forward looking array which is embedded in a cavitator for generating a gaseous cavity which minimizes hydrodynamic noise resulting from turbulent pressure fluctuations. A marine vessel incorporating the sonar system includes a hull, a hydrofoil suspended beneath the hull by a strut, and a cavitator for generating a laminar flow over the hydrofoil and for creating a cavity for eliminating turbulent flow contact. The cavitator is located at a leading edge area of the hydrofoil. The sonar array is embedded into the cavitator.
