Wind tunnel model in the open measuring section of the RWG

Wind tunnel model in the open measuring section of the RWG
The model is attached to the movable RWG centreboard via a cranked support rod, which enables the angle of attack of 15° to be varied automatically without access to the measuring section. This set-up is typical for carrying out 6-component force measurements in the wind tunnel. The supersonic nozzle can be seen on the left-hand side of the picture.
