Length variable mast for engineering measurement in wind tunnels as probe carrying arm

摘要

The mast consists of a single step telescopic adjustable conical tube with fixing or securing facilities, part pieces and adapters. The overall length is firstly adjusted coarsely by combining the part pieces and the adapters in steps, then the length can be finely adjusted by a telescopic adjustment. The length of a mast is not varied by a gradual stepwise combination of equidistance part pieces, but by combinations of different length modules (part pieces) permitting variation.
