Elliptical nozzles: the shape of silence? This project aims to leverage the aeroacoustic properties of elliptical nozzle geometries to significantly reduce installed jet noise. This project expects to generate new knowledge regarding methods to reduce installed jet noise, a serious problem for the aerospace industry.

This project aims to leverage the aeroacoustic properties of elliptical nozzle geometries to significantly reduce installed jet noise. This project expects to generate new knowledge regarding methods to reduce installed jet noise, a serious problem for the aerospace industry. Regulatory constraints inhibit the implementation of efficiency-increasing configurations but still fail to eliminate public health impacts. Expected outcomes include a set of tools for optimizing nozzle designs capable of significantly reducing installed jet noise. This will provide significant benefits, as jet noise is a serious health issue for the Australian public. This project represents an opportunity to reduce its impact while improving fuel efficiency.Read moreRead less
Powering optimisation of large, energy-efficient multihull vessels, operating at critical speeds. Australia is currently the world leader in the design and construction of large aluminium vessels. The existing fleet of vessels is under pressure from increased fuel prices and regulatory requirements to reduce emissions; this project directly addresses the need to develop new energy-efficient multihull vessels using computations and model testing.
Probabilistic terrorism risk assessment and risk acceptability for infrastructure protection. The risk-based decision-making framework will enable security risks to be quantified and compared in a rational and consistent manner, for a range of terrorist threats to infrastructure and transport systems. This will allow risk mitigation to be maximised leading to optimal security expenditure.
Risk-Based Decision-Making for Terrorism and Infrastructure Security. The project intends to develop stochastic models to predict the likelihood and extent of damages, casualties and other losses from terrorist and military threats. Terrorism, security and defence policy-makers need robust probabilistic risk assessments to prioritise or optimise the protection of buildings and aviation infrastructure, as well as iconic structures and mass gatherings. A key focus of the project is malevolent and ....Risk-Based Decision-Making for Terrorism and Infrastructure Security. The project intends to develop stochastic models to predict the likelihood and extent of damages, casualties and other losses from terrorist and military threats. Terrorism, security and defence policy-makers need robust probabilistic risk assessments to prioritise or optimise the protection of buildings and aviation infrastructure, as well as iconic structures and mass gatherings. A key focus of the project is malevolent and accidental explosive blast loadings on civilian and hardened infrastructure. A quantitative assessment of security risks and risk acceptance criteria would allow the effectiveness of security measures to be assessed to provide cost-effective levels of protection that is acceptable to society.Read moreRead less

Summary
The Future of Urban Routing and Navigation. This project aims to develop new efficient techniques for mixed-initiative routing in large transportation networks. Current state-of-the-art techniques for real-world journey planning take user requirements as input and generate a few proposed journeys as output. However, the most useful decision-support systems are mixed-initiative: the Information Technology (IT) system and user work together to find the best decisions. In the context of journey pla ....The Future of Urban Routing and Navigation. This project aims to develop new efficient techniques for mixed-initiative routing in large transportation networks. Current state-of-the-art techniques for real-world journey planning take user requirements as input and generate a few proposed journeys as output. However, the most useful decision-support systems are mixed-initiative: the Information Technology (IT) system and user work together to find the best decisions. In the context of journey planning, interaction with the user is needed to find the best combination of private, public and active transportation; understand trade-offs between cost, starting time, journey time, convenience and reliability; and react to delays and disruptions. This project aims to develop dynamic decision-support systems that will help travellers reach their destinations cheaper, faster and more conveniently.Read moreRead less
Remote sensing to improve structural efficiency of high-speed catamarans. This project aims to develop a monitoring system to remotely measure ship motions, loads and ride control activity under commercial operations. Data will be analysed using advanced statistical methods to inform evidence-based design to improve both structural efficiency and passenger comfort.

This project aims to develop a monitoring system to remotely measure ship motions, loads and ride control activity under commercial operations. Data will be analysed using advanced statistical methods to inform evidence-based design to improve both structural efficiency and passenger comfort. The research will impact on design rules used worldwide, reducing weight and increasing payload and transport efficiency for this class of vessel. A "Smart” semi-autonomous interface will be developed to provide on-board seakeeping guidance to the ship captain. This technology will have significant benefits such as increased ship safety, vessel longevity and improving passenger comfort for all types of vessels worldwide including high-speed catamarans.Read moreRead less
Fluid-thermal-structural interactions on high-speed aerospace vehicles. Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing. This project will desig ....Fluid-thermal-structural interactions on high-speed aerospace vehicles. Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing. This project will design and perform first-of-kind experiments that reproduce the complex fluid-thermal-structural interactions representative of those experienced by these aircraft and rockets. We will then use these measurements to assess, validate and improve the current state-of-the-art of simulation and modelling approaches for design.Read moreRead less
Understanding multi-scale reinforcement of carbon fibre composites. Addition of nano scale entities, such as nanotubes, on the surface of a carbon fibre forms a bottle-brush like architecture and strengthens fibre-matrix interface. This project will pioneer development of a systematic approach for analysis and design of such multi-scale reinforced composite materials for use in aerospace and civil industries.
