DTA Research Anticipates NH90 Arrival

The Defence Technology Agency is part of a research cluster that has won funding for a four year research programme into advanced fibre composite structures. Advanced fibre composite structures will be a feature of the Air Force’s new NH90 helicopters.

Mr Brian Shaw, a Research Engineer in DTA’s Applied Vehicle Systems, says: ‘The fuselage structure of the NH90 is almost entirely made of fibre composites. This includes all of the shell and the majority of the underlying primary and secondary support structure. The rotor blades are also composite. Carbon fibre in particular is used extensively throughout the structure, with the addition of kevlar and e-glass in selected areas. These composite materials provide the NH90 with a light, yet extremely strong structure that is effectively corrosion free and highly resistant to fatigue cracking.

‘DTA is currently building its composites expertise in anticipation of the support it can offer the RNZAF. Its participation in the New Zealand composites cluster (IRL, Air New Zealand, High Modulus and The University of Auckland) provides a unique opportunity to participate in relevant composite research programmes and build relationships with key industry players.’

The research programme aims to expand the knowledge and expertise related to innovative fibre composite structures, and in particular their manufacture and performance. This will be achieved by developing analysis, design, manufacturing and characterisation methods for advanced composite materials and structures.

The research will be managed and implemented by a steering committee, members of which are: The Centre for Advanced Composite Materials at the University of Auckland; Industrial Research Limited, and industry partner High Modulus; Air New Zealand Design Engineering; and the Defence Technology Agency. Each industry partner is contributing to the programme, but the primary funder is the government’s Foundation for Research, Science and Technology’s Research for Industry scheme, which is providing nearly $3 million over the next four years.
