Konstruktion av upprätningssystem för CICLoPE

Sammanfattning

Today there is no way of measuring or simulating turbulent flow in high Reynolds number

environments. The computational power required to simulate these conditions is not expected

to be available for several decades so instead the CICLoPE project aims at solving this

shortage by the construction of a long carbon fiber wind tunnel in which real measurements

can be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 meters

in diameter and 110 meters long, is as straight as possible.

This master thesis treat the design and construction of a device which may be used to align the

tunnel along a reference laser beam. A design is presented which allows the pipe to be aligned

within about a quarter of a millimeter along its entire length. Contents span over several

science fields such as physics, mechanics, control theory and electronics.

The result is a theoretically correct design. Further a first version of a device has been

manufactured which is not a finished product but rather a foundation upon which more

functionality can be built.
