Abstract: A control simulation platform is designed for UH-60 helicopter /T700 turbo-shaft engine integrated system numeric simulation. The simulation platform includes two parts:host computer program and slave computer program, and they are both developed by VC++ programming language. Host computer program is composed by UH-60 helicopter and T700 turbo-shaft engine real-time mathematical model, and the slave computer program simulates the embedded engine model and main rotor dynamic model,and carries out a variety of online optimization modes. The two programs above communicate with each other in real time based on TCP/IP protocol, so the transient and state process can be simulated for the integrated helicopter and engine system subjecting to surrounding and control parameters. Simulation results in some optimization control modes are also given throughout the simulation platform, respectively, including those which improve the helicopter traditional performance.The main rotor speed are kept constant or not, and the fast power-tracking mode can improve the helicopter maneuverability. All the simulation results show clearly that the simulation platform can provide an feasible validation in the early stage to implement an new integrated engine /helicopter control system.
