Minimizing hypersonic skin-friction by boundary-layer combustion. The high drag associated with hypersonic flight has been a major obstacle to development of hypersonic aircraft. It is generally accepted that half the drag of hypersonic vehicles will be caused by air friction on the aircraft's skin, due mainly to the turbulent boundary layer which forms on the skin. However, a new method of reducing skin friction, by injecting and burning fuel in the boundary layer, has been discovered. This ....Minimizing hypersonic skin-friction by boundary-layer combustion. The high drag associated with hypersonic flight has been a major obstacle to development of hypersonic aircraft. It is generally accepted that half the drag of hypersonic vehicles will be caused by air friction on the aircraft's skin, due mainly to the turbulent boundary layer which forms on the skin. However, a new method of reducing skin friction, by injecting and burning fuel in the boundary layer, has been discovered. This project is aimed at investigating the range of conditions under which this method will be effective. By this boundary-layer "lubrication" much more efficient hypersonic flight will be possible.Read moreRead less
Enhancing scramjet performance by boundary layer combustion. Australia has developed a strong international reputation over the past 20 years for excellence in research into hypersonic flight technologies. This helps to reinforce the fact that this is a country in which advanced technologies can be conceived and developed. Australian companies and agencies are already collaborating with and are being supported by international organizations to develop further hypersonic flight technologies. Achi ....Enhancing scramjet performance by boundary layer combustion. Australia has developed a strong international reputation over the past 20 years for excellence in research into hypersonic flight technologies. This helps to reinforce the fact that this is a country in which advanced technologies can be conceived and developed. Australian companies and agencies are already collaborating with and are being supported by international organizations to develop further hypersonic flight technologies. Achieving another significant advance in this area by demonstrating significant reductions in frictional drag on hypersonic vehicles will keep us at the forefront of this field and lead to continued international support and collaboration.Read moreRead less

The recent advances in wireless technologies are offering new opportunities for ubiquitous information access in on-board mobile computing. Realising an effective on-board mobile computing infrastructure poses significant technical challenges at both application and data transport layers. Our approach features the integration of techniques from satellite communications, anticipatory transport protocols, and personalised data management systems. The final outcome will be generic techniques and concepts for effective and efficient on-board access to global information sources and services (e.g., weather information, stock quotes, and infotainment). These concepts and techniques will have wider application scope, such as aeronautical, maritime and terrestrial public transport systems.Read moreRead less
