| Abstract: | NF-6 wind tunnel is the first pressurized continuous transonic cryogenic two dimensional wind tunnel in China. The performance of NF-6 wind tunnel depend up on axial compressor to large extent. This paper presents the selection and layout of a wind tunnel compressor for driving NF-6 wind tunnel. For the selected compressor, the torsional vibration of rotor system is analysed. 2 DC motors are connected in series mode to drive the compressor. The synchronization of two motors are ensured by quality control in manufacturing and by a speed feed-back regulation system. A trial operation in Oct, 2003 showed the feasibility of the NF-6 wind tunnel compressor system. |
