Along with the deployment of low Earth orbit satellite constellations for global satellite Internet services, such as Starlink, Ku/Ka/V band microwave signals from space will be available anywhere on Earth 24/7. Utilising the microwave signals, this project aims to investigate a high-resolution cost-effective solution to position and track un-cooperative flying objects, and expects to generate new knowledge in the area of remote sensing and to make Australia the leader in passive flying objects positioning and tracking. This should provide significant benefits, such as enabling new applications for future drone delivery systems or aerial taxi services, and benefiting the air transport industry, the defence industry, and bird conservation.Read moreRead less

This project aims to apply innovative methods developed in Australia to determine the optimal nuclear fusion reactions to synthesise new superheavy elements. As part of a major international collaboration aiming to discover elements 119 and 120, the project leverages our new conceptual approach, unique detector instrumentation and Australia's Heavy Ion Accelerator Facility. Anticipated outcomes include the first direct Australian contribution to the discovery of new elements, improved understanding of nuclear fusion and fission at the limits of nuclear existence, tests of our new theoretical approach to energy dissipation in many-body quantum systems, strengthened international links, and top-level nuclear science and accelerator training.Read moreRead less
The science of scramjet propulsion. This project will study the science of scramjet operation at high Mach numbers and develop the understanding required for operation at such conditions. The outcomes include experimentally validated scramjet models operating at speeds never reached before, and the potential to extend the known flight envelope for air breathing propulsion.
Optomechanical refrigeration of electronic circuits. The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-ef ....Optomechanical refrigeration of electronic circuits.

By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less

Summary
Design optimisation and physical behaviour of fuel injection and mixing for innovative scramjet concepts. Scramjets are a potential game changer for satellite launch and high speed flight. The phenomena that will make or break them are complex, and achieving optimal designs is hugely challenging. This project combines advanced optimisation techniques and flow simulations to find, and understand, optimal fuel injection for innovative scramjet designs.

Hypervelocity Roughness-Induced Laminar-Turbulent Transition for Advanced Scramjet Flow Control. Scramjet technology is set to make air-breathing flight beyond five times the speed of sound a reality. At such speeds, complex aerodynamic phenomena are likely to cause flow separation in the scramjet, hence significantly affecting its operability. This project will establish the applicability of discrete surface micro-roughness elements to induce the laminar-turbulent transition of hypervelocity bo ....Hypervelocity Roughness-Induced Laminar-Turbulent Transition for Advanced Scramjet Flow Control. Scramjet technology is set to make air-breathing flight beyond five times the speed of sound a reality. At such speeds, complex aerodynamic phenomena are likely to cause flow separation in the scramjet, hence significantly affecting its operability. This project will establish the applicability of discrete surface micro-roughness elements to induce the laminar-turbulent transition of hypervelocity boundary layers, with the purpose of energising the surface flow entering the engine so that it can sustain higher adverse pressure gradients without separating. This project will undertake a targeted ground test program to characterise the physical mechanisms of hypervelocity roughness-induced laminar-turbulent transition.Read moreRead less
Flow physics of porous wall fuel injection for scramjet combustion and drag reduction. This project combines world-class Australian scramjet science with German advanced high temperature materials, exploring potentially transformational technology for satellite launch. Australia’s credentials in the international space arena will strengthen, contributing to assured access to the space-based applications upon which we heavily depend.
