Master Thesis Report Parameterisation and Reconstruction of the NASA Rotor 67 • Determine the index value of the point at which the change in tangent value between adjacent point reaches the minimum for both the suction and pressure side curve • Using the index values of both the pressure and suction side curves, compute the average tangent values for both the blade metal inlet and outlet angle. With these information, the BM will be able to calculate the initial camberline. Interactively, the steps taken to construct the camberline on the blade modeller is as follows: • Import and plot the original points on the BM • Reorder the points using the selected first and second index values • Specify the location of the suction side of the blade and the points closest to the leading and trailing edge of the blade. Use the ’Extract Main Info’ command to determine the initial cam- berline • Re-plot the ordered points with separate numbering for the pressure and suction side curve respectively. Once the ’Extract Main Info’ command has been initiated, the computed camberline will then appear on the BM interface together with the plotted points. Further manual adjustment of the camberline’s leading edge position, trailing edge position as well as its mid control point are possible on the BM interface. Within the BM, the ’pos LE’ and ’pos TE’ enables minor adjustment away from the selected leading and trailing edge marker. An illustration of the plot of original and re-ordered points are shown in figure 4.4 and 4.5 respectively. The plot of the separately reordered suction and pressure side points as well as the plot of points with initial camberline are shown in figure 4.6 and 4.7. 135 5253 136 54 55 56 56 57 58 5 70 9 60 6 69 1 62 63 51 50 49 48 4 7 46 45 44 43 42 4 410 39 38 37 36 35 28 129 4 −0.028 −0.029 −0.030 −0.031 −0.032 −0.033 144145146 147 143 142 141 140 1 39 138 7 130 131 132 133 137 8 122 123 124 125 −0.028 134 −0.030 −0.032 −0.034 127 1 −0.090 68 6465 126 −0.089 −0.088 −0.087 −0.086 −0.085 −0.084 −0.083 −0.088 −0.086121 −0.084 −0.082 120 119 −0.080 34 118 66 33 67 32 Figure 4.4: Plot of Original Point Coordinates Figure 4.5: Plot of Re-ordered Points Coordinates Before a discussion is made on the fitting algorithm for the pressure and suction side curve, the development of the ordering algorithm will be presented. This algorithm is used earlier when the points are re-ordered for the purpose of reconstructing the camberline and the pressure/suction side curves. From an initial starting point selected by the user, the ordering algorithm is used to find the next adjacent point. In order to find the adjacent point, a tangential line is projected from the current point using the computed discretized axial distance (dx) and its derivative of the previous pair of 117 30 6PDF Image | Aerodynamic Design of the NASA Rotor 67 for Non Uniform Inflow
