摘要： An aerodynamic element (often referred to as a vane or fletching) that is operatively coupled to the nock end (the back) of an arrow that adds significant stability associated with vanes of similar height (referred to as “high profile” in the archery community) without the noise (amplitude and frequency) commonly associated with such vanes while also providing low drag characteristics. The vane has an initial front or leading edge at a shallow initial angle relative to the axis of the arrow. When the vane is mounted at an angle (known as offset or helical) to the axis of the arrow, this front shallow initial angle (and area under it) is utilized as a vortex generator. This vortex mixes and therefore helps balance velocities in the lower pressure, large aft area which is initiated at a point along the leading edge that increases to a steeper angle relative to the initial angle. The top of the vane is parallel to the axis of the arrow for stability as well as sound advantages. The back edge of the vane then angles down at a steep angle in a straight line to help with noise as well as control airflow.

摘要： Applicants have invented a guidance system for guiding a projectile, the projectile having a body portion capable of being spun in a first direction and a nose portion connected to the body portion by a spin control coupling, the nose portion being capable of being spun in a second direction. The nose portion including first and second aerodynamic surfaces fixedly attached to the nose portion and configured and arranged to cause the nose portion to spin in a second direction during projectile flight. The nose portion including third and fourth aerodynamic surfaces fixedly attached to the nose portion, which are configured and arranged such that when the nose portion is spinning the third and fourth aerodynamic surfaces have no net effect on projectile flight, but when the nose portion is despun using the spin control coupling, the third and fourth aerodynamic surfaces induce both a moment and a lateral force to the nose, causing the projectile flight path to change.

摘要： A cylindrical device connected to the nose of a projectile for imparting n to the projectile fired from a non-rifled bore of a cannon. The device has at least two coaxial, adjacent, and integrally connected cylindrical segments of different diameter. The segment having the larger diameter is positioned most rearwardly of the projectile, relative to the nose of the projectile, and the periphery of this segment has circumferentially spaced angled slots for catching air moving past the projectile to spin the projectile. The segment with the smaller diameter attaches the cylindrical device to the aft end of the nose of the projectile and directs the flow of air to and through the angled slots of the segment having the larger diameter.

摘要： An unconventional advanced air-to-surface weapon of monowing configuration, and having a symmetrical, high lift fuselage of lenticular (i.e., biconvex or oblate) cross section, with a width-to-thickness fineness of approximately 2.5. The longitudinal profile is modified Sears-Haack in two dimensions, truncated at the base for a rocket nozzle. The weapon comprises a nose portion modular forebody, a weapon payload portion modular midbody, and an aft boattail modular portion which are combined into one unit that is selectively separable into its modular components when used. A variation of this weapon is also taught which features a semi-lenticular fuselage cross section (i.e., one flat side) and a width-to-thickness fineness of approximately 2.1.

摘要： A gun-fired spin-stabilized projectile of good aerodynamic shape (i.e. with a long forward tapering section) is centered in the gun barrel at its forward end by means of a series of circumferentially spaced apart permanently fixed radially extending projections, and at its rearward end, by means of either the maximum diameter of the projectile body or by means of a driving band mounted on a rear portion of the body. In the latter case, the maximum diameter of the projectile body is slightly less than the diameter lands of the gun and the driving band is constructed in such a manner as to be separated from the body after firing by centrifugal force and air drag.

摘要： A caseless cartridge with a projectile, a propellant, and an ignition source. The ignition source is configured to ignite the propellant in response to an activation of the firearm. The propellant is molded around the projectile and is configured to propel the projectile from the firearm upon ignition. When the firearm is activated, the propellant is consumed, and the projectile and the ignition source are discharged from the firearm. The projectile has a bullet, an ignition housing, and a shaft. The bullet is positioned on a leading end of the projectile, while the ignition housing is positioned on a trailing end opposite the leading end. The shaft extends between the projectile and the ignition housing. The projectile may also have a plurality of fins to stabilize the projectile during flight and a plurality of ignition ports. The ignition source may ignite the propellant through the plurality of ignition ports.

摘要： Projectile guiding assemblies, caps and methods of delivering power for testing and optionally data over spring-mounted fin(s) of the guiding assembly are provided. The guiding assemblies are configured to have continuous electrically conductive path(s) from the fin(s), through the respective spring(s) on which the fin(s) are mounted, and into the electronics module, which may receive power for testing and guiding data from external source(s) over the electrically conductive path(s). In the testing state, cap mechanically secures the fin(s) to contact(s) thereupon to assure continuous power and data transfer, sparing surface area that was previously dedicated to power and data transfer and simplifying these processes, especially under field conditions.
