Experiment on aero-engine altitude simulated pressure distortion

  • 摘要: 鉴于航空发动机高空压力畸变试验的重要性,详细介绍了试验方案,通过插板,进行了航空发动机高空压力畸变试验,获得了基于插板扰流条件下的航空发动机气动稳定性特性,并初步获取了压力畸变、高空低雷诺数、引气和功率分出等关键降稳因子对该发动机稳定性影响的数量关系.压力畸变、高空低雷诺数以及引气、功率分出因素对临界综合畸变指数影响为:高度1km至高度18km,临界综合畸变指数降低了11.11%,高度1km至高度20km,临界综合畸变指数降低了14.69%.为航空发动机高空气动稳定性提供验证平台和试验数据支持.
