In order to meet requirements of the new generation of aviation aircraft with electromechanical and en- ergy integration, co - simulation of multi - disciplinary coupled system is studied. For unified interfaces of heterogeneous simulation models, simulation data exchange and synchronization scheduling control, key technologies of dis- tributed co- simulation based on Functional Mock- up Interface （FMI） are studied. Firstly, mathematical philoso- phy of co - simulation is established by numerical integration method and analyzed in detail. Secondly, distributed co - simulation architecture based on FMI is built by using distributed and client/server structure. The master algorithm of co - simulation is proposed by integrating processes including the rule of data exchange at communication point and the method of synchronization scheduling control during co - simulation. The flow of co - simulation client and the implementation of the corresponding FMI interfaces are described. Finally, the example from prototype system is giv- en to demonstrate the effectiveness of the master algorithm of distributed co - simulation based on FML
