摘　　要：通过对F-135发动机结构与短距起飞/垂直降落原理的分析,基于simulink仿真平台建立了由三轴承喷管、升力风扇和滚转喷管组成的发动机数学模型。将各部件推力在地面坐标系中进行分解,并结合机体当前姿态,利用simulink中的6DOF工具,建立了飞/发一体化模型;采用单一变量原则,分别通过调节发动机转速和飞行高度,对发动机动力模型各部件推力进行仿真验证,并将三轴承喷管推力仿真结果与外文文献中推力数据进行对比,最大误差仅为1.85%,验证了发动机动力模型的有效性;通过对机体位置和姿态进行仿真,验证了飞/发一体化模型的有效性。Through the analysis of the F-135 engine structure and the principle of short takeoff/vertical landing,based on the Simulink simulation platform,an engine mathematical model consisting of a three-bearing swivel duct,a shaft-driven lift fan and a rolling nozzle was established.The thrust of each component was decomposed in the ground coordinate system,and combined with the current attitude of the fuselage,the 6 DOF tool in Simulink was used to establish an aircraft/engine integrated model.Using the single variable principle,by adjusting the engine speed,the thrust of each component of the engine power model was simulated and verified.By adjusting the flying height,the three-bearing nozzle thrust was simulated,and the simulation results were compared with the thrust data in foreign literature.The maximum error was only 1.85%,which verified the effectiveness of the engine power model;The simulation of the position and attitude verifies the effectiveness of the integrated flying/fading model.
