WebApr 12, 2024 · The influence of the semi-vertex angle of the conical shell on the critical free-stream static pressure is given in Figure 10. It can be observed that with the increase in the semi-vertex angle, the critical free-stream static pressure decreases accordingly. Furthermore, the natural frequency is inversely proportional to the semi-vertex angle.
