Abstract: 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.

Abstract: An axial loaded explosive bolt that can repeatedly be used for the purpose of remotely or automatically activating a timely separation of adjoining walls separated by a finite distance by the means of either an explosive charge or activation of a pressurized gas line. The fastener includes two bolts with internal bores that are attached by the means of a two-piece encapsulation connected by an inter-connecting clasp. The fastener assembly employs the use of either a combination of a thermal igniter and a pyrotechnic charge or a pressurized gas line attached to a solenoid valve and pressurized gas storage unit to supply a force sufficient to properly separate the said mechanical fastener assembly.
