摘要
采用CFD技术,对高超声速冲压发动机冷流状态下阻力特性开展了数值模拟研究。对发动机不同部件的阻力大小及不同阻力类型的占比进行了对比分析,为发动机性能预测和评估提供了有效支撑。
Using CFD technology,a numerical simulation study was conducted on internal drag characteristics of scramjet under cold flow conditions.The drag of different parts of the engine and the proportion of different drag types were compared and analyzed,which provides effective support for engine performance prediction and evaluation.
