Revival of silicon solar cells for space applications. Development of very thin silicon solar cells for space applications. These space cells will include many of the significant improvements in silicon cells of the last 20 years, which have allowed close to the maximum possible efficiencies and the order of magnitude decrease in cost of terrestrial solar cells. Space cells require good radiation resistance to give good end of life performance. This project will use photovoltaic architectures, p ....Revival of silicon solar cells for space applications. Development of very thin silicon solar cells for space applications. These space cells will include many of the significant improvements in silicon cells of the last 20 years, which have allowed close to the maximum possible efficiencies and the order of magnitude decrease in cost of terrestrial solar cells. Space cells require good radiation resistance to give good end of life performance. This project will use photovoltaic architectures, proven to give high performance for terrestrial cells, to develop ultrathin silicon cells with extreme light trapping and improved radiation tolerance to give high beginning and end of life efficiencies. These cells will be less than 5% of the cost of multijunction cells currently used in space.Read moreRead less
Electron Transpiration Cooling of Hypersonic Vehicles. Future aircraft for flight at hypersonic speeds require sharp leading edges for the best aerodynamic performance. Sharp leading edges incur high heat loads and cannot be adequately cooled with current technologies. The project aim is to investigate novel surface materials that emit electrons when heated. This emission of electrons from the surface can significantly contribute to the cooling of the sharp leading edges. This project is expecte ....Electron Transpiration Cooling of Hypersonic Vehicles. Future aircraft for flight at hypersonic speeds require sharp leading edges for the best aerodynamic performance. Sharp leading edges incur high heat loads and cannot be adequately cooled with current technologies. The project aim is to investigate novel surface materials that emit electrons when heated. This emission of electrons from the surface can significantly contribute to the cooling of the sharp leading edges. This project is expected to deliver new experimental data on novel surface materials exposed to a hypersonic flow environment and computer models that can simulate their cooling effect. This investigation will contribute towards enabling technologies for sustained hypersonic flight by overcoming critical head load limitations.Read moreRead less
Wind Tunnel Testing of a Hypersonic Plasma Engine. This project intends to evaluate an electric engine that is capable of speeds in excess of 10000 km/hr, for access to space and responsive surveillance in our region. The expertise of Lockheed Martin, Lockheed Martin Australia, the University of Qld and DST Group are to be combined to complete experimental and theoretical evaluations of an air-breathing plasma engine that is capable of out-performing rockets and scramjets. US Air Force Research ....Wind Tunnel Testing of a Hypersonic Plasma Engine.

The expertise of Lockheed Martin, Lockheed Martin Australia, the University of Qld and DST Group are to be combined to complete experimental and theoretical evaluations of an air-breathing plasma engine that is capable of out-performing rockets and scramjets. US Air Force Research Laboratory results will also be compared and shared. This project provides opportunities for young Australian researchers to be participate and lead an exciting new field of propulsion. It is anticipated that the program will be the foundations to future flight demonstrations from Woomera, Australia.Read moreRead less
