Development of an active noise control system for sleeper seats on large commercial aircraft. Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here.

Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here. Efficiency and robustness problems that affect existing ANC systems will be addressed. A prototype system will be produced for a business class sleeper seat in a wide body aircraft. A second outcome is the establishment of a robust integrated system design procedure that can be used to quickly develop ANC systems for future designs.Read moreRead less

Summary
Integrated silicon carbide nanosensors for monitoring extreme environment. This project aims to develop a highly sensitive and reliable sensing platform for structural health monitoring in harsh environments, encompassing high temperature, corrosion, and shock. These conditions have been posing several technical challenges to sensing and electronic devices. The project elucidates the piezoresistive and thermoresistive effects in silicon carbide nanowires, which are the building blocks of robust ....Integrated silicon carbide nanosensors for monitoring extreme environment. This project aims to develop a highly sensitive and reliable sensing platform for structural health monitoring in harsh environments, encompassing high temperature, corrosion, and shock. These conditions have been posing several technical challenges to sensing and electronic devices. The project elucidates the piezoresistive and thermoresistive effects in silicon carbide nanowires, which are the building blocks of robust mechanical and thermal sensors used in extreme conditions. The findings from this project expect to provide Australia with the cutting-edge expertise necessary for developing next-generation monitoring systems in the extreme environments of the oil/gas transportation, mining, automobile, and space exploration industries.Read moreRead less

Summary
Resolving the mechanics of wall-mounted finite airfoil noise production. Noise from air transportation and wind turbines is a rapidly growing component of environmental noise pollution that must be reduced to improve public health and well-being. A submarine must also have a low acoustic signature to ensure its stealthiness. The common source of noise generation among these technologies is the airfoil, yet we do not understand how they create noise in real, complex environments. This project aim ....Resolving the mechanics of wall-mounted finite airfoil noise production. Noise from air transportation and wind turbines is a rapidly growing component of environmental noise pollution that must be reduced to improve public health and well-being. A submarine must also have a low acoustic signature to ensure its stealthiness. The common source of noise generation among these technologies is the airfoil, yet we do not understand how they create noise in real, complex environments. This project aims to understand how fluid flow interacts with a wall-mounted finite airfoil to produce sound. The project aims to identify the noise producing physics via a novel wind tunnel experiment and numerical study. This enhanced understanding will create better airfoil noise prediction and control strategies in the future.Read moreRead less
Resolving the mechanics of turbulent noise production. This project aims to dramatically develop our capacity to quieten modern transport, energy and defence technologies through a better understanding of how fluid turbulence creates sound. The outcome of the project will be a quieter modern environment leading to improved public health, an improved environment and a more secure nation.

This project aims to establish the first Australian national facility for non-destructive evaluation, consisting of a three-dimensional scanning laser vibrometer, laser shearography, and an optical de-rotator, to enable full-field characterisation of the deformation and damage state of materials and structures. This solution is expected to perform rapid, broad-area scans, characterise dynamic response and wave propagation in human-engineered or natural structures, and diagnose rotating systems. This will enhance experimental capabilities, with uses spanning many industry sectors including aerospace, naval, automotive and medical.Read moreRead less
