Low-speed wind tunnel tests were conducted on four types of joined-wing aircraft models. Various ratios of horizontal tail to wing span were employed (40 percent, 60 percent and 100 percent.), and the leading-edge at the tip of horizontal tail was joined to the trailing-edge of the wing for three configurations. In addition, in one configuration the tips of the horizontal tail and the wing were overlapped using the 100 percent ratio. The horizontal tail has minus 22 deg dihedral and minus 25 deg sweep angles (25 percent chord line). And the main wing has respectively corresponding angles of 10 deg and 40 deg. The results indicated that the area and location of horizontal tail significantly effect the aerodynamic characteristics of the joined-wing aircraft.
