ABSTRACT	The longitudinal aerodynamic characteristics of tapered annular wings(TAWs)were numerically simulated by extending the equations of the quasi-vortex lattice method(QVLM)for planar wings.Wind-tunnel experiments using two thin-wing models were also conducted to obtain the longitudinal and lateral characteristics of the TAW.The longitudinal aerodynamic characteristics of the experimental and calculational results were compared.As a result,the agreement was good except the drag coefficient.
