Study of compression ratio distribution in two-stage series turbocharged aircraft piston engine

  • 摘要: 针对某款航空活塞发动机建立仿真建模,并通过实验验证了模型的准确性和适用性;根据匹配要求,进行了增压器选型分析。考虑不同飞行高度中冷器效率和各部分流动阻力变化的前提下,以增压压气机耗功最小为优化目标研究了在全飞行高度运行工况下不同压比分配对发动机增压性能的影响,探究了最适压比分配规律,以此为依据总结出一套基于实验制定二级增压压比分配方案的方法,使二级增压器能全工况运行在高效率区且保持7%以上安全裕度,为基于安全性的二级涡轮增压航空活塞发动机的研制奠定了基础。
