교육용 초음속 풍동 개발 및 성능검증에 관한 연구

A small size - low priced supersonic wind tunnel of which test section size is 30㎜ by 35.6㎜ and run time is 20sec is developed. This educational supersonic wind tunnel is an intermittent blowdown type with an exchangeable nozzle block. In this study, the proper sized and low priced commercial parts are used to reduce the total cost of supersonic wind tunnel. A nozzle design and small supersonic wind tunnel design process has been established, and it is confirmed that a given supersonic flow field has been obtained and proved by experiment.
