POWDER FORM | 5 |
| 20130145949 | END-BURNING PROPELLANT GRAIN WITH AREA-ENHANCED BURNING SURFACE - An end-burning grain of a solid rocket motor or other gas-generating device is supplemented with one or more sticks of high-burn-rate propellant embedded in a matrix of a relatively low-burn-rate propellant. The sticks increase the burning surface area as the grain burns by forming conical indentations in the surface. | 06-13-2013 |
| 20150300789 | Pyrotechnic Gas Generator Component - The invention relates to a pyrotechnic gas generator component including an inlet stage formed by a pyrotechnic detonator composition and an intermediate stage disposed between the inlet stage and an outlet stage formed by at least one gas generator composition, said intermediate stage being formed by a compressed black powder layer. | 10-22-2015 |
| 20090193994 | TAPERED COMPRESSED POWDER CHARGE FOR MUZZLELOADER AND BLACK POWDER FIREARMS - A clean burning premeasured compressed charge for use in black powder firearms as well as cartridges. The premeasured compressed charge is manufactured to have a substantially desired shape which facilitates improved flame propagation by the leading end wall and along the exposed sidewall surfaces of the compressed charge to result in a more complete and rapid burning of the compressed charge both from the leading end wall toward the trailing end wall and also radially inwardly from each one of the four sidewalls toward a center of the premeasured compressed charge. The premeasured compressed charge has a leading end portion and a trailing end portion and the leading end portion is either the same size or a smaller dimension than the trailing end portion. | 08-06-2009 |
| 20140261040 | GENERANT GRAIN ASSEMBLY FORMED OF MULTIPLE SYMMETRIC PIECES - Pressed and segmented gas generant grain assemblies formed from a plurality of symmetric gas generant pieces or segments are disclosed. The symmetric pieces or segments are arranged circumferentially to define a substantially round, segmented body. In certain variations, the symmetric segments are substantially free of polymeric binder and have a high density. The segmented pressed grain assemblies are more robust and less expensive to manufacture, while still exhibiting desired combustion performance. Methods of making such segmented gas generant grain assemblies are also provided. | 09-18-2014 |
| 20140352566 | NITROGLYCERINE-FREE MULTI-PERFORATED HIGH-PERFORMING PROPELLANT SYSTEM - The propulsion system for the acceleration of projectiles is based on a multi-perforated grain propellant and is composed from nitrocellulose, a crystalline energy carrier of a nitramine type and an inert plasticizing additive. The number of perforations is 2 to 6, preferably 4. The propellant grains can have round or polygonic profiles, depending on the number of perforations. The preferred grain geometry is cubic with a rectangular grain profile. The nitramine compound contains a structural element of the general chemical structure formula R—N—NO2, where R is a residual group. The nitramine compound is present in a concentration in the range from 0 to 35% by mass, in particular in the range from 5 to 25% by mass. The nitramine compound is preferably RDX. The inert plasticizing additive is a water-insoluble polyoxo compound, if necessary in combination with a substance containing carboxyl groups. In layers near the surface an increased concentration can be present. The inert plasticizing additive is present in a concentration of 0 to 10% by mass, preferred 0 to 5% by mass. | 12-04-2014 |

| 20100269722 | SUPPORT MEMBER FOR SUPPORTING SHELL, AND METHOD - The invention relates to a support member for supporting a shell into the barrel of a breech-loading weapon, and a method. The support member ( | 10-28-2010 |
| 20100288150 | ARRANGEMENT FOR SUPPORTING SHELL INTO BREECH-LOADING WEAPON BARREL - The invention relates to an arrangement for supporting a shell into the barrel of a breech-loading weapon. The arrangement comprises a support piece ( | 11-18-2010 |

PROPELLENT CHEMICAL CHARGE CONTAINER | 2 |
| 20120097060 | PROGRESSIVE PROPELLANT CHARGE WITH HIGH CHARGE DENSITY - A method for producing propellant charges with progressive combustion characteristic and a higher charge density than previously considered possible to achieve, intended in the first instance for direct-firing barrel weapons such as tank cannons. Combined in the charge are at least two radially perforated propellant tubes, which are arranged in their entirety inside or after one another, and which have at an e-dimension selected in relation to the actual type of propellant and its desired combustion characteristic, combustion or ignition channels, and which have circular outer and inner boundary surfaces, in conjunction with which, before initiation of the charge, at least one of the total number of outer surfaces of these propellant tubes that are available for initiation has been treated with an inhibition, surface treatment or surface intended to delay the propagation of ignition to that surface so that the combustion of the propellant tubes is partially mutually overlapping. | 04-26-2012 |
| 20120132098 | SLEEVE FOR ACCOMMODATING PROPELLANT CHARGE POWDER - The invention relates to a combustible sleeve for accomodating propellant charge powder, to munitions designed using such a sleeve, and to a production method for such sleeves. The sleeve ( | 05-31-2012 |

WADS | 2 |
| 20140366765 | DEGRADABLE SHOTGUN WAD - Herein we describe shotgun shells each having a degradable wad comprising a polyhydroxyalkanoate polymer, as well as methods for ensuring that such wad degrades quickly after landing in an aquatic environment. Plastic, aquatic debris has a negative economic and ecological impact, and thus it is advantageous to use implements that will degrade into environmentally benign compounds. Incorporating a degradable wad into shotgun shells provides an effective, economical solution. Suitable degradable shotgun wads and methods are described herein. | 12-18-2014 |

WITH EXTENDABLE ARMS | 1 |
| 20100162915 | DEPLOYABLE PROJECTILE - A method for protecting a second location against a first projectile fired from a first location at the second location. The method including: firing at least one second projectile toward the first projectile; and increasing a footprint of the second projectile via a deployment from the second projectile to prevent the first projectile from striking the second location. | 07-01-2010 |

BOMB LANCE | 1 |
| 20160187114 | AREA DENIAL SYSTEM - A propelled lance provides a wounding non-lethal anti-opponent action by piercing an enemy's foot or other contacting body part with a lance penetrator. The lance penetrator lodges in the body and further penetration is optionally impeded by an integrated stop device. The lance penetrator optionally inserts an RFID, other identification, tracking, or other payload into the enemy. The lance penetrator provides anti-personnel, anti-vehicle and anti-robot action. | 06-30-2016 |
