Research on coupling system of unmanned helicopter

Unmanned helicopter is used in various fields and tasks with its advantages of low cost and strong survivability. This paper focuses on the application of unmanned helicopter logistics transportation, systematically analyzes the characteristics and modes of unmanned helicopter suspension system, and obtains the coupling system model of unmanned helicopter and suspension system by carefully deriving the dynamic model of unmanned helicopter and suspension system, and then carries out the research on flight dynamic modeling.
