Achieving appreciable thrust for both cruise and accelerating flight in scramjet engines is only half the solution for a viable engine. Equally important, is the design and validation of a vehicle structure capable of withstanding the sustained high thermal loads, and the resulting thermally induced structural stresses.

Scholarships of $35,000 (AUD) are available for PhD students who have achieved Honours 1/High Distinction in their UG program and/or have completed a Masters by Research.
An FRP sandwich structure consists of two high strength composite skins separated by a core material. Inserting a core material between the laminates increases the stiffness of the panel without increasing its weight. FRP sandwich panels are very popular in the aerospace and automotive industries, and various core materials, such as balsa, PVC, PET, honeycomb, are available to satisfy the needs of these industries.
Accelerating hypersonic flight is characterised by rapidly changing flow conditions and high heat loads. To achieve sustained combustion in these engines, fuel injectors must be capable of also rapidly responding to changing flow conditions to ensure efficient and effective fuel delivery is maintained.
Direct Simulation Monte Carlo is a ubiquitous simulation method for low-density flows. It involves statistical simulation of representative populations of molecules in rarefied gas mixtures. The technique can simulate many physical processes very accurately at much less computational expense than direct molecular dynamic modelling.
Copper chrome arsenic (CCA) timber is a major waste that is currently being stockpiled around Australia. The strict environmental restrictions on their disposal means that this stockpile will increase annually. This project looks at optimising the choice of acids for leaching of CCA from the timber, an understanding of the rate processes and chemical equilibrium that determine the extraction efficiency of those elements, and the recovery of the copper, chromium and arsenic from the waste stream.
Wood-cement composites particleboards are made of wood chips combined with a cementitious material. Usually, they are manufactured into panels for use by the construction industry in applications such as walls, roof sheathing and tiles, floor, and sound barriers. They have been around for a very long time. However, it is only in recent years that there is a renewed interest in their use. Indeed, because of their excellent thermos-physical properties these panels are ideal candidates for use in green buildings. They are environmentally friendly because they can sequester carbon within.
This project is part of a much larger vision to measure complexity of projects from subjective views for task and resource allocation purposes. Several competency models have been proposed and used in defence.
The pervasive cyber threat to DoDs, public sector and industry means cyber vulnerability and penetration assessment (CVPA) and testing is no longer an option but rather about managing an acceptable risk of how much testing is enough (Christensen, 2017 & 2015).
