Current commercially available systems for pulsed gas metal arc welding (GMAW-P) monitor electrical characteristics of the arc and attempt to compensate for process deviations by pulsing current at a ...SBIR Phase I 2006 ArmyDepartment of Defense
IBRs represent a great advance for military aero-engine performance. However increased performance has its price: high manufacturing costs and difficulty with in-service repair. Linear friction we ...SBIR Phase I 2007 Air ForceDepartment of Defense
Integrally Bladed Rotors - IBRs - are an important part of current and future military aeroengines. The use of IBR allows lower weight rotors with decreased drag and improved compressor efficiency. ...SBIR Phase II 2008 Air ForceDepartment of Defense
Machining of titanium parts from wrought stock costs as much as $1000 to $1500 per pound of finished component and has material lead times up to one year. Electron beam deposition, or e-BAM, seeks to ...SBIR Phase I 2009 Air ForceDepartment of Defense
This project proposes the use of non-imaging optical measurement to discern the weld pool oscillations occurring during electron beam deposition, and thereby to infer the weld pool size. By knowing ...SBIR Phase I 2009 Air ForceDepartment of Defense
