Purposes of this research are to obtain design data of an engine-nacelle for a USB powered high lift system on a STOL aircraft, which is being developed by the National Aerospace Laboratory. In these design data, structure and strength of the engine-nacelle and conformity between an engine and its engine-nacells are the most important problems. In order to obtain engine operational characteristics for mixing a fan and a core flow, a test was performed using a FJR 710 turbo-fan engine installed in a circular confluent exhaust duct. Test parameters of interest are the length of the mixing zone and the contraction of the mixing nozzle. As a result of this investigation, it has been proved that a power-turbine output decreases with an increase of outlet pressure of the power-turbine due to the mixing. And a clue to a design method to correct engine operational matching characteristics was found.
