Abstract : Many types of wind tunnels have been proposed for transonic testing of aircraft models at high reynolds numbers. While some form of stored-energy system is needed in order to avoid exorbitant running costs, designs can vary considerably in the extent to which effective use is made of the mass of air stored in the circuit, in the energy input needed between runs, and in the quality of flow in the test section. Some of the most promising designs can be considered as variants of same thermodynamic cycle, and a generalised study has been made of their relative merits.
