Intermittent wind tunnel - Intermittent wind tunnel

…In low-speed and high-speed subsonic wind tunnels, the airflow is created by operating a blower continuously, but in wind tunnels at supersonic speeds and above, the airflow is often created by releasing pressurized air stored in an air tank. The former are called continuous wind tunnels, and the latter are called intermittent wind tunnels. Continuous wind tunnels are divided into two types: a closed-loop type in which the airflow circulates in a closed circuit, and a open-loop type in which the airflow does not circulate. …

*Some of the terminology used to refer to "intermittent wind tunnel" is listed below.

…低速風胴や高速亜音速風胴では送風機を連続的に運転して気流をつくるが，超音速以上の風胴では貯気槽に充てんした高圧空気を放出して気流をつくるものが多い。前者を連続式風胴，後者を間欠式風胴という。連続式風胴は，気流が閉じた回路を循環する回流式と気流が循環しない吹抜け式に分けられる。…
