Abstract: A printed structure including a plurality of overlying layers of elongate polymeric filaments stacked on a surface of a substrate. The elongate polymeric filaments are stacked on each other along their lengths to form a liquid impermeable, self-supporting wall. The liquid impermeable self-supporting wall forms a wall angle of about 30° to about 90° with respect to a plane of the surface of the substrate.

Abstract: A safe and reliable multi-component projectile enables cost effective manufacturing and assembly of the projectile. Major components of the projectile are joined by a plurality of shear pins interfacing with scalloped geometry of the components. The components are then held together by forcibly joining them using a hybrid annular-cantilevered snap fit joint. The tooth and groove arrangement exists where the teeth are at the end of a spring-leaf like feature of one of the mating parts and the groove is located on the opposite mating part.

Abstract: The present invention is a pyrotechnic time delay system that is improved over prior-art designs. Specifically, the system described herein comprises at least one delay element. The delay element or delay elements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.

Abstract: A modular constructed, standardized test device for simulating a spin stabilized projectile which is fired from a barrel having rifling grooves, comprised of the bolted together, keyed to transfer spin, modular components of replaceable rotating band, replaceable front end and back end, and filler sections for further simulation of other components. The front end has an interior recessed area which allows for a selective integration of a threaded fuze or an aerodynamic, electronic, or other structure and the rear end has a crimp groove for selective attachment of a cartridge case, and aerodynamic or other structure to mimic the rear geometry of a projectile for testing purposes.

Abstract: Method of fabricating a dummy practice ammunition round to dynamically match behavior of an existing live ammunition round during manually cycling of the action, or other demonstration. A dummy practice ammunition round of identical contour is formed, having a center of gravity (mass) in the same position as on the existing live ammunition round. Weight is matched by removing or omitting material through coring into the case head of the round or by hollowing it out.

Abstract: A 40 millimeter (mm) projectile is capable of deploying a payload out of the rear of the projectile. The projectile carries the payload an extended distance from the muzzle and then disperses the payload after a command is provided to the projectile. The projectile includes a proximity fuze which allows it to sense a target and disperse the payload at a given distance from the target. Alternatively, a time-based fuze or radio frequency (RF) based fuze may be employed instead. The payload may be used against a variety of targets, such as personnel, vehicle or aerial targets. In addition, the projectile could be used as a training device for proximity, preprogrammed or RF-controlled fuzed projectiles.

Abstract: A modular shelter system includes a floor panel having a first curved surface along a lateral edge on a top side of the floor panel and a first inside surface located inside of the first curved surface. The modular shelter system additionally includes a wall panel having a second curved surface along a bottom end of the wall panel, wherein the second curved surface is configured to rotate relative to the first curved surface, and wherein the second curved surface is configured to mate with the first curved surface. The wall panel further has a second inside surface located inside of the second curved surface, wherein the second inside surface is configured to mate with the first inside surface when the wall panel is erected over the floor panel.
