The 2 m supersonic wind tunnel is an intermittent blowdown-ejector wind tunnel with a full-steel structure. The general structure and main sections are designed and studied based on the characteristics of this wind tunnel, such as large structural size, multiform operational states, high flow quality, quick test section and model conversion, wide Mach number adjustment range for full flexible nozzles, etc. In the course of design, key components and difficult sections are researched by means of testing and solved with our design experiences. Finite element analysis is widely employed for theoretic calculation. A novel multi-layer sinter-wire mesh is used to reduce the strength of current noises, and flexible nozzles and test sections are incorporated in the design to eliminate step influence and improve flow quality, aero-caster movement technology is adopted to convert test sections and models quickly and steadily. Design rationality is proved by structural parameter static state debug,hydraulic testing, vibration inspection and flow quality detection. Applications of new materials and technology are found to be successful.
