| dc.description | The directional sensitivities of the DISA Type 55P61 crossed-wire probe and DISA Type 55P91 gold-plated triple-wire probe were investigated using a modified calibration set-up with three very accurate orthogonal axes of rotation. The yaw factor k<sub>T</sub> and pitch factor k<sub>N</sub> which account for the cooling effects of tangential and binormal velocity components respectively were determined at different yaw angle a and pitch angle theta at velocities of 6 m s<sup>-1</sup>, 11 m s<sup>-1</sup> and 19 m s<sup>-1</sup>. Based on these measured values, the relative errors in the calculated flow velocity were computed with constant values of k<sub>T</sub> and k<sub>N</sub> at alpha and theta =60 degrees , 90 degrees and k<sub>T</sub>=0, k<sub>N</sub>=1. The effects of k<sub>T</sub> and k<sub>N</sub> cannot be neglected, especially at high alpha and theta . For the DISA Type 55P61 crossed-wire probe, the suitable values are k<sub>T</sub>=0.30 and k<sub>N</sub>=1.14. For the DISA Type 55P91 triple-wire probe, they are k<sub>T</sub>=0.20 and k<sub>N</sub>=1.01. |
