Aerodynamic forces and moments acting on a flight body in unsteady motion should be analyzed to develop airplanes, rockets, and other flight vehicles, especially for these models in free flight condition. In the past, most of the experiments to know aerodynamic forces and moments acting on a flight vehicle were carried out by a force balance. A rod supporting a body, which is connected to the force balance, has some effects on the airflow around the body. The method with a series of video pictures recording a flight motion will be a strong tool for measurements of aerodynamic forces and moments. On the other hand, it is necessary to install a gauge on a measured object, although the cylinder gauge has been used in the past research, existence of the gauge influences the aerodynamics of the body. In the research, the method applied to an arbitrary configuration body is proposed and the validation was studied.
