Aerospace Grade Lattice Block Structures for High Performance Missile Structures Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-045 Topic Title: Aerospace Grade Lattice Block Structures for High Performance Missile Structures Proposal No.: N091-045-1428 Firm: Transition45 Technologies, Inc. 1963 North Main Street Orange, California 92865-4101 Contact: Edward Chen Phone: (714) 283-2118 Abstract: This SBIR Phase I project evaluates and develops a robust design and affordable manufacturing process for producing aerospace quality and strength lattice block structures (LBS) from high temperature metallic materials that are suitable for Navy missile airframe applications. At the present such a design and production method does not exist. A key benefit for using conventional metals such as superalloys and titanium alloys is that these are established high temperature materials for which designers are comfortable in using given the extensive properties database that exists. High temperature titanium alloys, in particular, are considered a key class of materials that could enable lighter weight missiles. Lattice block structures made using high temperature intermetallics such as titanium aluminides should also be possible with the technology proposed here. The technology to be developed in this work is an extremely flexible yet cost-effective fabrication process that will be applicable for both limited and volume production of missile components. Benefits: Anticipated benefits include high performance, ultra-lightweight yet affordable structural components for various industries and systems. Potential commercial applications include airframe and aero-engine structures and components for weight reduction, spaceframe components including thermal protection systems, armor and structures for automobiles and trucks, corrosion and petrochemical pump and valve components, shipboard structures, furniture, and building structures.
