【摘要】 NF 6风洞是我国唯一一座增压连续式跨声速翼型风洞,为了提高实验雷诺数,在设计上还具有喷氮降温的功能。笔者介绍了NF 6风洞马赫数控制系统的组成、特点及运行方式,对转速控制子系统、压缩机静叶角控制子系统、二喉道栅指控制子系统等进行了较为详细的介绍。更多还原

【Abstract】 NF-6 wind tunnel is a pressurized continuous two-dimensional transonic wind tunnel, which is the only one in China. In this paper, the Mach number control system in NF-6 wind tunnel is introduced, especially in detail for the compressor rotary speed control sub-system, the compressor stator vane control sub-system and the second throat control sub-system.更多还原
