Aiming to the issue of difficulty in carrying out joint simulation resulting from different degree of complexity of models and different modeling tools for each subsystem at UAV design stage.This paper puts forward a kind of joint simulation method of air vehicle heterogeneous model based on FMI(Functional MockupInterface)standard.By taking the model of the flight dynamics and engine model of a certain type of UAV,FMI interface models for all subsystems are generated and MatLab Simulink software is adopted to achieve joint integration and transfer of subsystem models so that the efficiency of joint simulation of heterogeneous model is effectively improved.The research result can be referred to for engineering practice of UAV joint simulation.
