| 摘 要： | 为使混合排气二元收敛喷管的设计在满足发动机推力性能要求的同时,也具有良好的红外特征信号抑制效果,从固定式混合排气二元收敛喷管的设计要求出发,提出了一套混合排气二元收敛喷管气动与红外隐身综合设计的方法和流程.并通过算例计算验证了该设计方法的可行性.另外,计算结果表明：二元喷管的进口截面位置、喷管总长、出口面积以及出口宽高...

| Abstract: | A design method of two-dimensional convergent nozzle of mixed flow turbofan engine was developed to meet aerodynamic and infrared stealth requirements.The feasibility of the design procedures was verified by numerical simulation.And the results indicate that nozzle inlet section position,nozzle length,throat area and aspect ratio properly play a key role for the required nozzle gross thrust.Choosing a reasonable aspect ratio is important for meeting the infrared stealth requirement. |
