The combination of underground DC superconductor cables and voltage source converter (VSC) based HVDC terminals operating at moderate DC voltages (approximately +/-200kV) creates a new option for transmitting power over long distances with multiple collection and distribution point, creating a virtual, longdistance, high power DC bus-bar. This combination of technologies has the potential of transmitting 5,000 -10,000MW or more, over distances exceeding 1500 km while exhibiting the lowest power losses of any transmission technology. The system has the potential to be cost competitive with overhead EHV AC and traditional HVDC transmission technologies.

Future aircraft engine development may lead to Advanced Ducted Engines (ADE), which have a bypass ratio significantly higher than present turbofans. The increases in bypass ratio will dictate larger diameter nacelles and an increasing importance of the nacelle aerodynamics and wing integration aerodynamics. A series of isolated wind tunnel tests was therefore designed and conducted by PWA and MTU to investigate inlet, nozzle, and reverser aerodynamics. Additional installed testing was done in cooperation with MBB and BAe. Key features of the tests are noted and significant results are discussed.
