Innovative Non-pyrotechnic Dispersion Device (INDD) Navy SBIR FY2004.2 Sol No.: Navy SBIR FY2004.2 Topic No.: N04-169 Topic Title: Innovative Non-pyrotechnic Dispersion Device (INDD) Proposal No.: N042-169-0 Firm: Mide Technology Corporation 200 Boston Avenue Suite 1000 Medford, Massachusetts 02155-3502 Contact: Marthinus Schoor Phone: (781) 306-0609 Web Site: www.mide.com Abstract: Kinetic energy munitions that dispense and disperse pellets prior to impact are effective against threats on the ground or at sea. Typically, explosives or pyrotechnics also contained within the munition are used to impart a lateral velocity to the pellets. Unfortunately, explosives pose a severe injury risk to our military handlers, and impose high shipping costs associated with hazardous material transport (Class A, B, or C). The Navy desires a safer and cheaper dispersion alternative to the explosives in kinetic energy munitions. Mid� proposes a dispense and dispersion mechanism that leverages the incredibly high energy density characteristics of Shape Memory Alloys (SMA), and the thermal energy already present in the airframe structure. Strain energy in SMA induced by the high munition temperatures can be harnessed, then transferred to the pellets, providing the required lateral velocity for a wide strike footprint. Benefits: Replacing the explosive kinetic energy generation with Shape Memory Alloys results in reduced injury hazard to our military handlers and minimizes expensive transport costs associated with Class A, B, or C materials. The extremely high energy density of SMA's enables a non-pyrotechnic munition to retain overall mission effectiveness (strike footprint) by providing sufficient lateral velocity to the kinetic energy penetrator pellets. Devices that expel high velocity pellets have commercial applications in material fabrication processes including replacement of gas jets in Rapid Solidification Process Tooling, and shotpeening.
