Title: The engine/airframe interference drag at cruise conditions using propulsion simulation
Abstract: A wind tunnel test procedure is described to determine from the thrust minus drag measurements the aircraft drag and engine/airframe interference drag at cruise conditions. The definitions of the thrust and drag terms in use are given. Engine thrust simulation is provided by a calibrated Turbofan Powered Simulator (TPS). Further the use of a blown nacelle as propulsion simulator is described and compared with the simulation by a TPS. It is concluded that TPS engines are valuable test tools, simulating the aircraft engine closely, but the blown nacelle can not be totally replaced by the TPS nacelle; it will retain its own applications
