摘要: Warhead structures and features are fabricated using direct manufacturing technologies, a method for fabricating bulk warhead structures by sequential and additive deposition of melted feedstock layers. Suitable energy sources for melting the feedstock can be various high energy density technologies including laser, electron beam, plasma arc deposition, and the like. The high energy density in combination with high cooling rates results in structures with homogeneous microstructures. The feedstock can be in the form of wire or powder and is applied to a substrate by introduction to a molten pool on the substrate, accumulating to additively combine with the substrate. The approach provides for warhead structures with singular and combined unique features to include: integral constructions, tailored fragmentation patterns, use of dissimilar materials for special effects, and variable material property constructions for enhanced performance.

摘要: A vehicle is disclosed having a hull with a longitudinal, vertical and lateral axis, the hull further having front end and rear ends and first and second sides. A turbofan engine mounted in said hull, said engine having an exhaust duct. First and second front exhaust nozzles are mounted on the first and second sides of the front end of the hull. First and second rear exhaust nozzles are coupled to the first and second sides of said hull at said rear. All of the exhaust nozzles are rotatable from a vertically downward position to at least a partially horizontal direction and incorporating shudders to adjust the flow rate of exhaust gas from said turbofan engine therethrough. A duct system for coupling the exhaust duct of the turbofan engine to all of the nozzles.
