Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

This paper will use computational fluid dynamics (CFD) to investigate the effects of a shroud to the thrust and power of a 9.5-inch rotor and 15-inch rotor. The results show that at the same rpm, a shrouded rotor can produce 20% more thrust than a free rotor. | Computational investigation of the effects of a shroud to the aerodynamic characteristics of rotors
