New ground transport system, Ground Effect Transport System (GETS), which has potential for solving the green house problem of the earth by saving fuel to transport because the system is expected to have high lift-to-drag ratio, had been newly proposed, and fundamental investigations needed to develop such transport system has been conducted in university laboratory level. In the present study, some of the essential aerodynamic characteristics of an wing-in-ground effect of the GETS is investigated experimentally. Namely, effect of the tandem wing height from the ground and the wing interference are investigated. The results are compared with the numerical simulation results. It was shown that the effect of the interference of the wings could be ignored when the distance became more than 2.5 times the chord length of the wings. It was also found to be important that the boundary layer of the ground plate should be eliminated in the experimental study of such system that required very small gap between the wing and the ground plate.
