The critical problems preventing a supersonic commercial transport going into service are the creation of sonic boom and poor fuel efficiency caused by large drag, both derived from shock wave. The "supersonic biplane theory" has been proposed to alleviate these problems. Previous research showed supersonic biplane wing can cancel out and reduce shock wave causing these problems. On the other hand, considering takeoff and landing, the low speed characteristics of the supersonic biplane is to be investigated. In this research, two-dimensional test was conducted to measure the lift and profile drag. The values were derived by integrating the static pressure measurements over the wing. Then the obtained results were compared with the computational results.
