In the NAL 6m low speed wind tunnel flow field measurements have been carried out by traversing only one yawmeter probe. But it consumes too much time to measure the flow field around a full-scale aircraft model with one probe, so a velocity vector measuring system with 13 asymmetric-wedge type yawmeters was developed in order to survey the flow field around the empennage of the NAL STOL research aircract model. The rotational angle of the 13 probes and the setting angle of this system are automatically controlled following the sequence previously programmed into a mini-computer system. As the principle of measurement used in this system is almost the same as that reported in NAL TR-594, this paper mainly describes the hardware of this system, the control modes, the data reduction, and the data processing. The accuracy of the flow angle measurement turned out to be satisfactory, but measurements of dynamic pressure and static pressure were less accurate. This paper concludes with an example of measurements taken of the flow field around the empennage of the NAL STOL research aircraft model. |
