Abstract
Tandem-Type WIG is recognized as a suitable layout for Rail-Way-Type WIG transportation system and other WIG crafts, because of its stability performance. Two aerofoil models, each of them having the same configuration are arranged as a tandem shape WIG and tested in the Low Turbulence Wind Tunnel with the fixed ground plate method at The Institute of Fluid Science, Tohoku University. Angle of attack and clearance height between the trailing edge and the ground plate are varied independently. Influence of the existence of forward WIG and the effect of change in it's ground clearance, and angle of attack to the Rear WIG aerodynamic characteristics are reported.
