Embodiment Construction
[0019] This embodiment is a circumferential air injection stabilization device at the trailing edge of an axial flow compressor.
[0020] refer to Figure 1 to Figure 5 . In this embodiment, the stabilizing device for circumferential air injection at the trailing edge of the compressor is characterized in that an applicable air injection device is designed and the main parameters are optimized, so that the air injection effect is optimal. The jet device consists of a suction surface and a pressure surface;
[0021] The two-dimensional coordinates of the axial flow of the suction surface are 0, 0; -3.0229, 1.0806; -4.1305, 2.0129; -4.7016, 2.9021; 3.7778,7.2411;-2.9486,8.0215;0,9;
[0022] The two-dimensional coordinates of the pressure surface profile are 0, 0; -1.8099, 1.0248; -2.9042, 2.1635; -3.4826, 3.3022; 8.9958; -0.7886, 10.134; 0.73215, 10.972; 1.8957, 11.338; 2.4775, 11.4; other points are obtained by spline interpolation to form a spline curve. According to the ...
