Propulsion/airframe integration (PAI) is one of the key technologies to realize an environmentally friendly and economically viable supersonic transport. Japan Aerospace Exploration Agency has studied engine/nacelle layout to improve cruise efficiency and to reduce sonic boom loudness. For the validation of PAI design, wind tunnel test technique is studied through the joint research with SUBARU CORPORATAION. In this study, ''Thrust-Drag Bookkeeping'' is focused on, and additional drags caused by PAI, such as the spillage drag, are measured. Through supersonic and transonic wind tunnel tests, knowledge on improvement of measurement accuracy was obtained. This report summarizes results obtained in the joint research.
