A suspending wind-tunnel test for the Automatic Landing Flight Experiment (ALFLEX) was conducted as a part of the research on an unmanned winged reentry vehicle (HOPE). The suspending flight was simulated in the wind-tunnel using a 40 percent scaled model of the ALFLEX vehicle to validate the design of the suspending system and to identify the aerodynamic characteristics of the vehicle for designing a control system. As a result, problems of some elements of the system are identified and a counterplan is considered. It is concluded that the system works well except for these problems, and that there is not much difference between the actual aerodynamic characteristics and the predicted ones used in designing the vehicle. The flight test plan of ALFLEX is then fixed based on these results.
