The engine tests at the simulated altitude test facility (ATF) are necessary in engine develop?ment. The differences in configuration, technique and the test requirements between high bypass-ratio tur?bofan with separated flow nozzles and low bypass-ratio turbofan were analyzed firstly. Then taking into ac?count the structure and the test capability of a new ATF in China, the technical research requirements for high bypass-ratio turbofan engine with separated flow nozzles test at this ATF were offered, and the techni?cal problems that should be resolved before the first ATF test were also confirmed. It would be helpful for the analysis of technical research requirements on the other new-type engine test at the ATF.
