引射器引气与压气机抽气建立加力燃烧室喷口低压条件的综合分析

Comprehensive Analysis of Low Pressure Condition Established with Ejection or Compressor Extraction for Afterburner Nozzle

从建设投资、运行费用、设计、操作、维护等诸多方面对引射器引气与压气机抽气建立加力燃烧室高空模拟试验器喷口低压条件进行全面分析和对比,得出引射器引气方案优于压气机抽气方案。

The low pressure conditions at the afterburner nozzle can be established on the simulated altitude test rig with ejection or compressor extraction. Through comparison and analysis, a conclusion can be obtained that the ejection is better than the compressor extraction. Invest, operation cost, design and maintenance are concerned in the paper.
