Research on the application of model-based system engineering in the design of bleed air system of high-speed vehicle
In view of the severe thermal load and high electrical load problems faced by the combined power high-speed vehicle,a model-based system engineering method is adopted for the design.The design starts from the new constraints of no shaft power output and high stamping air temperature in stamping mode.Based on the requirements,the logical architecture,physical architecture and component solution of the bleed air system of high-speed vehicle are designed.The system solution consists of core hardware such as air inlet,air-fuel heat exchanger and ram air turbine.The integration verification of the system solution is also carried out,which basically meets the constraints.The results show that the bleed air system solution can meet the energy requirements of high-speed vehicle during the cruise phase.It also shows that the model-based system engineering method can effectively promote the iterative system design and improve the reliability and efficiency of complex system design.
