20090173248 | Supercavitating Projectile and Operation Thereof - A method for operating a supercavitating projectile is disclosed. | 07-09-2009 |
20090173249 | Supercavitating Projectile and Operation Thereof - A method for operating a supercavitating projectile is disclosed. | 07-09-2009 |
20110017089 | CAVITY-RUNNING PROJECTILE HAVING A TELESCOPING NOSE - A projectile having a cavity-running mode is provided with a means for changing the diameter of its nose. Based on changed conditions, the diameter of the nose can be actively reduced or increased, as required, to maintain a desired value for the nose-to-body ratio of the projectile. | 01-27-2011 |
20110061554 | Acoustic Shotgun System - 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. | 03-17-2011 |
20110252996 | COUNTER-MINE DART - Some embodiments of the invention provide a dart that contains an HE payload, two time-delay fuses, one providing a relatively longer delay and the other providing a relatively shorter delay and two triggering mechanisms for triggering the fuses. The first triggering mechanism, which triggers on contact with a mine lid, triggers the relatively shorter time-delay fuse. The second mechanism, which triggers on overburdening exposure to water, sand, or soil, triggers the relatively longer time-delay fuse. | 10-20-2011 |
20110297031 | Surface Ship, Deck-Launched Anti-Torpedo Projectile - A surface ship, deck-launched anti-torpedo projectile is disclosed. The projectile has a blunt-end nose to create a cavitating running mode. The nose has a gradual, stepped, right-circular cylindrical or conic geometry. In some embodiments, the projectile includes a plurality of tail fins that are dimensioned and arranged to be within the generalized elliptical cavity that shrouds the projectile in the cavitating running mode. | 12-08-2011 |
20110297032 | CAVITY-ENHANCING FEATURES AND METHODS FOR A CAVITY-RUNNING PROJECTILE - A cavity-enhancing feature and method are disclosed for a projectile that is capable of operating underwater in a cavity-running mode. | 12-08-2011 |
20110308418 | Projectile Having Deployable Fin - A supercavitating projectile is disclosed that has deployable fins. The fins are pivotally coupled to the body of the projectile. The fins have two primary states: stowed within a recess at the surface of the projectile and deployed to a radially-extended position relative to the body of the projectile. The fins deploy as the projectile leaves its launch tube. The fins function as a control surface, interacting with the wall of the vapor cavity in which the supercavitating projectile travels. | 12-22-2011 |
20120012022 | DEVICE AND METHOD FOR WARDING OFF OBJECTS APPROACHING A SHIP UNDER OR ON WATER - A device is provided for warding off objects approaching a ship under or on water by using ammunition bodies to be detonated below the water surface, the device comprising: an ignition device programmable to the water depth at which ignition is to be carried out automatically. In order to selectively ward off objects approaching the ship, in the event of the presumption of a threat, the device may detect both the distance and the direction of the object approaching using an underwater positioning system, and transmitting the data to the actuators of a launching device of an ammunition launcher that is disposed on the ship, and positioned about two axes via a firing guide computer so that, after firing a respective ammunition body, the same strikes the water surface above the object at a precisely predefined region, or at a predetermined distance from the object. | 01-19-2012 |
20120085257 | SUPERCAVITATING PROJECTILE WITH REDUCED-DRAG CONTROL SURFACES - The illustrative embodiment provides bumpers which are roughly shaped like skis that face towards the air-water boundary of the air cavity. When the projectile fishtails and one or more of the bumpers come into contact with the air-water boundary, the water imparts torque and a rebounding force to push the projectile completely back into the air cavity. Furthermore, because the bumpers are shaped roughly like skis and not like knives, the bumpers do not penetrate the water or create unnecessary water drag. | 04-12-2012 |
20120097061 | SUPERCAVITATING PROJECTILE HAVING A MORPHABLE NOSE - A supercavitating projectile having a nose that is capable of morphing its shape or length for extended operating range is disclosed. | 04-26-2012 |
20160102955 | Impeller Cavitation System - A method and apparatus for stopping an impeller-driven watercraft is includes distributing a plurality of submunitions in advance of a path of the impeller-driven watercraft. Each of the submunitions includes a buoyant member, a first end cap, and a second end cap; the second end cap is heavier than the first end cap. A lanyard connects the first end cap to the second end cap, optionally passing through the buoyant member. At least one of the submunitions enters an intake vent of the impeller-driven watercraft and attaches to a blade of an impeller of the impeller-driven watercraft, causing cavitation and imbalance, thereby slowing the impeller-driven watercraft | 04-14-2016 |
