摘　　要：为满足某型气垫船推进系统的性能指标,开展基于国产化软件平台的机桨匹配算法研究。以某型气垫船的推进系统为对象,建立数学模型,并以基于Modelica语言的国产仿真平台MWorks为基础对该系统进行建模仿真。通过研究变螺距角、变转速时气垫船推进系统的性能,对机桨匹配算法进行优化。仿真结果表明,优化算法可满足螺距角变距时间要求、螺距角稳态误差要求以及燃机机动性能曲线要求,所提出的机桨匹配控制算法满足性能要求,研究结果可为类似气垫船推进系统设计提供借鉴。To meet the performance index of hovercraft propulsion system,a study of enging-propeller matching algorithm based on the domestic software platform is carried out.Taking the propulsion system of hovercraft as object,the mathematical model is established,and the simulation model of the system is carried out on the basis of the domestic simulation platform MWorks of Modelica language.By studying the performance of the propulsion system with variable pitch angle and rotational speed,the algorithm of engine-propeller matching is optimized.The simulation results show that the optimization algorithm can meet the requirements of variable pitch time,steady state error of pitch angle and maneuvering performance curve of gas turbine.The proposed control algorithm satisfies the performance requirement.The results can provide references for the design of the propulsion system for similar hovercrafts.
