摘要： When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for recreational shooting, competition shooting, small game hunting, pistol crossbow fishing and pistol crossbow scuba fishing. The main fault of the standard pistol crossbow bolt is they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short pistol crossbow bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, their irretrievability from any commonly used target. Therefore, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Most bolts do not have a nock. it has two FLAT WINGS for elevation stabilizing which creates an accurate and stable bolt flight. No other bolt has this type of flat wings. These features allow this bolt to be easily viewed in flight. This also allows this bolt to be used for competition shooting because these bolts can be easily located, scored and then retrieved from any type competition target. The shaft has a THREADED TIP to accept almost any type metal point.

摘要： A guiding assembly is adapted to be connected to a projectile and comprising a rear main unit adapted to be connected to the front end of the projectile, and a front main unit rotatably connected at its rear end to the front end of the rear main unit. The front main unit is adapted to rotate about a central longitudinal axis. A relative speed control unit is operable between the rear main unit and the front main unit and capable of providing spin braking force to slow the relative speed of rotation of the front main unit. An at least one guiding fin radially extends from the front main unit. The pitch angle of the fin is controllable by a return spring connected to the fin so that the pitch angle of the fin is growing as the aerodynamic pressure on the fin lowers and it is growing smaller as the aerodynamic pressure on the fin gets bigger.
摘要翻译：引导组件适于连接到射弹，并且包括适于连接到射弹前端的后主单元，以及在其后端可转动地连接到后主体前端的前主单元。前主体适于围绕中心纵向轴线旋转。相对速度控制单元可在后主单元和前主单元之间操作并且能够提供旋转制动力以减慢前主单元的相对旋转速度。至少一个引导翅片从前主单元径向延伸。翅片的俯仰角可以通过连接到翅片的复位弹簧来控制，使得当翅片上的空气动力压力降低时翅片的俯仰角度增加，并且随着翅片上的空气动力学压力变大，翅片的俯仰角变小。

摘要： A flechette has a forward body (20) containing its center of gravity which is connected to a tail section (24). The tail section has a pair of fins (24A, 24B) each having a preselected longitudinal angle and radial angle. When the two fins are viewed from the aft of the flechette, the pair of fins demonstrate a S-shaped orientation. The size, shape and orientation of the pair of fins provide aerodynamic stability to the flechette while allowing the flechette to be stacked with like-shaped flechettes. The two-piece assembly of the flechette easily accommodates the use of different density materials for the respective pieces.

摘要： A flechette has a forward section or body (12) containing its center of gravity. A quill (10) is connected to the forward section and is integrally connected to a pair of fins (15A, 15B) each having a longitudinal angle and a radial angle. When the two fins are viewed from the aft of the flechette, the pair of fins demonstrate an S-shaped orientation. The size, shape and orientation of the fins provide aerodynamic stability to the flechette while allowing the flechette to be stacked with like-shaped flechettes in rows and columns or in a radial, circular arrangement. When stacked in rows and columns or in a circular arrangement, each flechette has its nose oriented in the same forward direction.

摘要： An aerodynamic projectile is provided having a shell with an aerodynamic structure and a controlled center of gravity, and which exhibits improved aerodynamics and resulting accuracy, and which is suitable for less lethal uses. The projectile shell has a closed front cavity housing a payload, such as a marking agent, therein. The projectile shell also has an open rear portion to provide access to the open rear cavity, and to decrease the weight of the projectile and appropriately locate the center of gravity. The projectile shell also includes a plurality of fins on a sidewall member to enhance the accuracy of the projectile.

摘要： A projectile and stabilizer therefor are provided. The sliding stabilizer is used instead of fixed or glued tail feathers, vanes or other fletching as a means for stabilizing projectile flight. The invention improves current projectile technology with reduced assembly labor cost, the elimination of bow clearance issues, improved accuracy with the consistent production of the sliding stabilizer, easy replacement of the stabilizer in the field, and improved projectile storage. A sliding stabilizer is designed to slide along the shaft of a projectile and comprises a circumferentially extending wing and a plurality of fins. In use, the stabilizer is positioned at the front of the projectile prior to launch, and the projectile slides quickly through the stabilizer until secured at a stop position at or near the trailing end of the projectile. An annular arrow fletch and arrow stabilizer are also provided. The annular arrow fletch may be used for; stabilizing arrow flight, providing better clearance and functionality then conventional fixed glued tail feathers. A stabilizer may be used with light emitting diode arrow nocks. The stabilizer may improve arrow shaft stabilization technology with reduced assembly labor cost, the elimination of facial and or face mask interference issues providing more clearance, improved accuracy, repeatable production with the consistent injection mold production of the annular arrow fletch, easy replacement of the annular arrow fletch in the field, and improved arrow storage. An annular arrow fletch may incorporate a metallic contact point, which will work with all light emitting nocks. A design of an annular arrow fletch may be affixed to an arrow by an arrow nock and may comprise an annular wing, a central elongated cylindrical cylinder with a cap and a plurality of fins with micro-groves and a metal contact. In use, the annular arrow fletch is affixed at the aft end of the arrow by an arrow nock prior to launch.
