Modeling and analysis of multi-helicopter coordinate system with slung load

  • A generic simulation model of multi-helicopter cooperated system with slung load by using elastic cable has been developed for research on control and avionic instrumentation. Flight dynamic models of each helicopter and payload were developed respectively. Elastic cables were treated as spring/damping systems, and the dynamics of each helicopter and slung loads was tightly coupled by elastic cables'dynamics. Simulation model of helicopter system with slung load was built, and analysis of stability and trim were conducted. The results indicate that slung load obviously affects each helicopter's dynamics properties based on qualitative analysis, and the modeling method is validated and feasible for multi-helicopter system with slung load.
