燃气轮机-可控螺距螺旋桨推进装置并行数字计算机实时仿真

Real-time Simulation of Gas-turbine Driven Controllable-Pitch Propeller Propulsion by Means of Parallel Digital Computers

本文介绍三轴燃气轮机及可控螺距螺旋桨推进装置的实时仿真数学模型，讨论用MIRAGE并行数字仿真工作站进行全数字实时仿真的技术问题。为了保证仿真的实时，并行数字计算机的计算步长与所选计算机数量和对象的复杂程度有关，选取较小步长必须使用较多计算机。

A real-time simulation model for three-shaft gas-turbine driven controllable pitchpropulsion is presented. The technique for digital real-time simulation by means of MIRAGE workstation is discussed. In order to meet the real-time requirements, it was foundthat depending on the complexity of the object, the choice of steplength for parallel computers would determine the number of computers required, the shorter the steplength, themore the number.
