Summary:Abstract Vertical wind tunnels play very important role in parachute training, helicopter rotor test, flight experience and other aspects, among which the double returns vertical wind tunnel has spread widely due to its low lose and low running cost. By using innovative structure design and finite element method, the general layout, research on design of supports and important sections are completed. The design part mainly describes glass flight section, integrated fan section, wind speed adjust device, ventilation door and the whole raft foundation structure. The dynamic debugging results show that the double return vertical wind tunnel has rational design, little vibration and high efficiency.
