Modeling and retrofit of certain turbojet

  • The static performance model of certain small turbojet installed in some unmanned-air-vehicle (UAV) was established based on object-oriented component-level aero-engine simulation modules, and its fidelity was verified by data comparison between simulation and original experiment. Whereafter, according to the engine-balance principle, some practical retrofit schemes of redesigning the axial flow compressor were given using the components-matching method under the precondition of maintaining the work-line of the centrifugal compressor and within the limitation of structure-durability and heat-load of the turbojet. The simulation result demonstrates that the retrofit schemes are effective in improving the turbojet-s general performance including thrust and specific fuel consumption (SFC).
