Polyurethane Sandwich Panel Systems for Ship Hull Reinforcement

The Royal New Zealand Navy (RNZN) regularly patrol the waters of the Sub- Antarctic Islands and the Southern Ocean in support of the Department of Conservation and Ministry of Primary Industries. Operation in these waters includes the potential presence and threat from ice, and RNZN Offshore Patrol Vessels are protected against ice with a belt of thicker steel about the waterline. Excessive pitch and roll of vessels can however result in thinner and more vulnerable areas of the hull being exposed to sea ice.

Integration of NZDF Remotely Piloted Aircraft Systems (RPAS) into New Zealand Civil Airspace

Integration of Remotely Piloted Aircraft Systems (RPAS) into civil airspace is a complex problem that is being investigated within New Zealand and internationally. For the New Zealand Defence Force (NZDF) seamless access to civil airspace would enhance RPAS operational capability for military training and non-military tasks, whereas current operational restrictions are likely to limit or preclude the use of RPAS for certain roles.

Impulse Noise Measurement and Assessment In The New Zealand Army: A Scoping Study

The New Zealand Army Landworthiness Authority has recently considered the risk of hearing damage in the NZDF due to impulse noise exposure. The need for a consistent noise database of all in-service weapons was identified, with a view to informing a hearing protection program. This report considers the problem of impulse noise measurement and assessment of noise exposure, with the aim of meeting the requirements of the Health and Safety at Work Act.

DTA Digital Image Correlation Capability

Digital Image Correlation (DIC) is a technique for optically acquiring full-field measurements of the displacement and deformation of a surface. This is achieved by observing the surface as it deforms, typically using one or more conventional monochrome digital cameras, and comparing the surface’s deformed and undeformed states using optical tracking.
