摘　　要：建立了UH-60直升机/T700涡轴发动机综合控制数字仿真平台。基于VC++环境开发了包含UH-60直升机/T700涡轴发动机综合实时模型的上位机程序,与运行机载涡轴发动机+旋翼实时模型及在线优化控制模式的下位机程序。两者基于TCP/IP协议实时通讯,可进行模拟实际直/发综合优化控制的数字仿真实验。在该数字仿真环境下,分别给出了提高直升机常规飞行性能的多种优化控制模式仿真、变旋翼转速优化控制以及快速功率跟随控制模式仿真,充分表明该平台可为新一代直/发综合系统的开发研制提供一个可靠的前期数字仿真验证。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.
