8 CONCLUSIONS
This paper presents a stage in the development of AT-
OWEC research, which involves the preparation of
physical test models at the Laboratory of Ocean
Structure Hydrodynamics, DOE - ITS. A number of
important aspects that have been explained can
further be summarized as follows:
• The AT-OWEC physical model measures 1 : 10
to the full scale, sized Dh = 400 mm and Hh =
550 mm, made of aluminum material, and has
been designed to meet geometric, kinematic and
dynamic similarities;
• The pitch motion measurement will be carried
out utilizing the gyroscope as primary
instrument, assisted by checking the target
visual tracing recorded through a digital
camera;
• Data acquisition system has been prepared with
appropriate tools to produce outputs that take
into account the appropriate calibration factors;
The results of numerical modelling of pitch moti-
ons have been prepared as data for comparative
studies with the results of the test model, which will
be implemented in the near future.
