摘　　要：导向器是航空发动机的重要部件,喉道面积作为其关键参数直接影响发动机动力性能。针对导向器喉道面积现有测量方法效率低、喉道面积估计不准的问题,提出了导向器三维测点处理与喉道面积精确计算的新方法,并在多联叶片导向器样件上开展了该方法与三坐标测量计算方法的对比实验。实验结果表明,所提方法得到的喉道面积更精确,且多次测量计算结果具有较高的一致性。Turbine nozzles were crucial components in aircraft engines,and the throat area was a key parameter that directly affected the engine s power performance.In response to the issues of low efficiency and inaccurate estimation in existing measurement methods for the throat area,a new method for three-dimensional measurement point processing and accurate calculation of the throat area for aircraft turbine nozzles was proposed.Comparative experiments between the proposed method and the CMM method were conducted on a multi-blade turbine nozzle sample.The experimental results show that the throat areas obtained by the proposed method are more accurate,and the results of multiple measurements and calculations have high consistency.
