摘要： A rear-deploying broadhead for an arrow includes a ferrule, a rear deploying blade, and a spring. The ferrule has a slot that receives the blade, the blade movable axially in the slot between a retracted position and extended position that presents blade edges when penetrating a target. A spring disposed on the shank of the broadhead applies a spring force to the blade when the blade is in the retracted position that maintains the blade in the retracted position during arrow flight.

摘要： A closed, self-contained ballistic apogee detection module for use in a projectile, such as a rocket, mortar round, or artillery round, fuses data from multiple built-in sensors, such as an accelerometer, a magnetometer, and a gyroscope, and processes the data using a microprocessor through a custom quaternion extended Kalman filter to provide accurate state and orientation information about the projectile so as to accurately predict apogee. The module outputs a signal indicating apogee detection or prediction which they projectile uses to initiate fuze arming, targeting control, airbody transformation, maneuvering, flow effector deployment or activation, payload exposure or deployment, and/or other mission activity. Because the system and method of the invention does not rely on external environmental data to detect apogee, it need not use a pressure sensor and can be completely sealed in and closed without requiring access to air from outside the projectile for barometric readings.

摘要： A laser weapon countermeasure device is described. The laser weapon countermeasure device comprises a sealed capsule having a filler disposed therein. The filler comprises either: a reflective particulate metal; or a precursor for a reflective metal or reflective metal alloy. The capsule is configured to burst in air such that the filler disperses into an aerosol. A countermeasure launcher and a vehicle comprising a countermeasure launcher are also described.

摘要： A drive mechanism for actuating a control surface of a vehicle that moves through a fluid medium. The mechanism directly translates the rotational motion provided by an input drive to a control surface that is used to direct the vehicle. The mechanism provides both weight and space savings as well as limits, if not eliminates, backlash. The angled drive mechanism may be particularly suited for use in applications such as UAV/UUV, munitions, and other relatively small platforms.

摘要： A method of making a polymer-coated, lead-free projectile. In an embodiment, the method comprises compressing a lead-free metal powder to form a green core, heating the green core to bond the lead-free metal powder to form a metal compact of desired strength and placing the metal compact into fluidized bed of polymer to bond polymer to the metal compact to form a polymer coated compact. A polymer-coated, lead-free projectile made according to the described method, and a loaded round comprising the polymer-coated, lead-free projectile are also disclosed.

摘要： A system and method for a modular, low lethal projectile is provided. The modular, low lethal projectile system comprises an exterior shell, propellant cartridge, and a projectile assembly. A propellant mounting area is arranged at a rear end of the exterior shell and is offset from a center of the exterior shell. A propellant cartridge is secured within the propellant mounting area. A firing pin of a firearm is configured to strike an edge of a cartridge primer of the propellant cartridge, which ignites a primer material and propellant within the propellant cartridge. The resulting hot, expanding gasses propel the projectile assembly form the firearm, and upon contact with a desired target, the capsule tube of the projectile assembly breaks, distributing an effective compound into the air around the desired target.

摘要： A device is disclosed for deflating a gas cavity about a projectile formed upon entry of the projectile into a liquid. The device can include a wall coupleable with a body operable as a projectile and defining an exterior and an interior space. The wall can be oriented toward a trailing end relative to a leading end defined by the body. The device can also include at least one inlet to facilitate gas flow from the exterior to the interior space. An outlet can facilitate gas flow from the interior space to the exterior and can be oriented toward the trailing end relative to the at least one inlet. Upon entry of the body and the wall into a liquid and formation of a gas cavity about a portion of the body and the wall, the at least one inlet can be located within the gas cavity and the outlet can be located outside the gas cavity, such that gas flows from the exterior through the at least one inlet to the interior space, and from the interior space through the outlet to the exterior to deflate the gas cavity.
