New Technology

Moreover, plans are being formulated for the implementation of a variety
of tests of large structures, including tests of large-sized panels related to
the development of commercial passenger aircraft, research and
development related to eco-wing technology, which is being promoted by
JAXA, and research and development into design technology for
high-strain, lightweight, composite constructions. We expect this testing
machine to play an even greater role in the testing of a variety of
large-scale partial structures in the aerospace field.
As a final note, I would like to express my gratitude toward all the
personnel from Shimadzu who were very helpful in getting this testing
machine installed.
