Institution National Aerospace Laboratory NLR Date 1982-02-28 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 Subject Windtunnel apparatusWindtunnel modelsInterference dragEngine airframe integrationAircraft modelsCruising flightThrust measurementsWind tunnel testsProcedures exhaust flow simulationPropulsion system performanNacellesComparisonTurbofan engines To reference this document use: http://resolver.tudelft.nl/uuid:54500ca8-e6ab-438e-b3e7-983102c690ca Publisher Nationaal Lucht- en Ruimtevaartlaboratorium Access restriction Campus only Source NLR-TR 82012 U Part of collection Aerospace Engineering Reports Document type report Rights (c)1982 National Aerospace Laboratory NLR Files PDF NLR_TR_82012_U.pdf 12.13 MB Close viewer /islandora/object/uuid:54500ca8-e6ab-438e-b3e7-983102c690ca/datastream/OBJ/view
