ABSTRACT	A low speed wind tunnel test was conducted for the 8.9％ model of the ALFLEX(Automatic Landing Flight Experiment) vehicle.The objectives of the experiment were (1)To clarify the effect of the makeshift sting support on the main flow;(2)to measure the forces and moments acting on the model;(3)to measure the hinge moments acting around the axes of control surfaces;(4)to measure thedetermination of the necessary ability of the actuators which operate the control surfaces,for confirmation of the size and configuration of the speed brakes,and so on.The visualization of the separated flow at the rear part of the model was,along with the surveillance of the boundary layer transition by the hot films,helpful to understand the actual flow behavior of the model.
