Research Institution
The nature of lattice fins allows them to be folded close to the weapon's structurewhen not deployed. That opens up the way for internal ordnance carriage, which leadsto the reduction of both flow field drag and radar detection. The high cost oflattice fin fabrication remains an issue. The current manufacturing process resultsin a per fin cost of roughly $2000. This Small Business Innovation Research Phase Iproject demonstrates a novel alternative waste-free process for fabrication oflightweight lattice fins, which enables 12-17 times reduction a cost per fin. Theproposed approach allows fabrication of net-shape fins of different web geometries(including very thin webs), use of different materials: metals, alloys, reinforcedplastics, composites. The process will be developed for stainless steel andcomposite lattice fins with different web thickness. Various candidate materials,including composites that could be viable fin materials will be evaluated and thecost savings associated with the utilization of the most affordable materials andproduction process will be established.It is anticipated that this Phase I program will result in the smallest, lightestlattice fin assemblies possible, consistent with the structural demands of themaneuvering weapon airframe. Viable material and manufacturing process advocated ina proposal will be equally applicable to the production of efficient lattice finsfor a 250-pound class munition, a 2000-lb munition, or any weight class in between.Commercial application includes lightweight metal sandwich panels for vehicle energyabsorbing components, automotive interiors, etc.
