ABSTRACT	One of the purposes of the Automatic Landing Flight Experiment (ALFLEX) is to estimate the aerodynamic characteristics of a vehicle with asult, the differences between the estimated characteristics and the results of the basic wind tunnel test were within the variation. Some other wind tunnel tests, however, showed significantly different results from the flight tests. These differences seemed to be caused by errors of the wind tunnel tests due to, for example, the effect of the supporting device. Although the results of the hanging flights were scattered due to measuremant errors caused by the effects of an umbilical cable, the method will be useful if the problem can be solved such as by using an inner battery.
